I have always considered Rodales to be among the most prostituted and
deceitful of all scuba magazines, in gear discussions.

Congratulations to Bob Evans!

Hi Dan,

            How are you?( I am Casey, the guy who ask about split fins &
strong current : )
            I have bought a Cressi Gara 3000 but I couldn't find a pair of
free diving fins for my girl friend because her feet are too small without
size. Anyway, have you try one of those force fin, are they good enough to
swim against current? Thanks.

Hi Casey,
Good choice on the fins for you. How are you liking them ?

Your girlfriend may be able to use a larger bootie, available from freedive
catalogs or custom wetsuit makers like "Aquatic Wetsuits". The freedive fin
neoprene socks are available up to 5mm and even 6 mm, which means a size 6
women's foot may fit nicely into a size 40 (European) freedive fin.
My girlfriend Sandra has size 7 feet, and uses one or 2 pairs of white
athletic socks--and a 2 mm neoprene sock ( the kind diveshops usually sell).
This has her very happy with her size 40 ( American size 8 men's) Picasso
Black Team freedive fins.

The athletic socks can work pretty well, if you can get past the look ;-)

Force Fins.....I have tried them extensively. I would say much better than
Twinjets or other split fins, but not as good as "real" freedive fins.
The way I see Force fins, is that Bob Evans has created many different
models of fins, and each one is best used by a person with a given level of
fitness--or lack of fitness. This was a very smart thing for Bob to do,
since divers come in MANY different fitness levels...... The original Force
Fin is best for the diver who has a heart condition, is morbidly obese, and
is in general, at a very low level of fitness. There are MANY divers like
this, even many instructors. But Force fin  has many other models that allow
"more water" to be pushed with each kick ( and with progressively better
levels of fitness, this is highly desirable) , and as you go to their more
advanced models, they do have some fins that can allow even a diver with
"elite level fitness",  to feel he or she is not at a disadvantage ( which
is how this same diver would feel with twin jets or Apollos on,  in a cross
current in Boynton).

I still like freedive fins best, but some of the Force Fins are much better
than most other fins on the market. Fit will not be a problem with them, and
they are very easy to use. You will need to get her the most advanced
model--the ones with the biggest fin surface. They have a new model now
which is very much like a freedive fin--you might try this one.

Hello Dan,

                First time when I used the Cressi 3000 I felt hard to kick
( I use Tusa split fins before ) compare with my old fins and it seems I
wasn't able to move as quick as my friends who used normal paddle fins. But
after 4 to 5 dives , I get used to them and no one could keep up with me
anymore!!! Gas consumption it just about the same now ( at the beggining it
consume more gas) , now couple of my friends are planning to buy freedives
fins, I really should thank you for all the kind advices, thanks Dan.

Casey,
Glad you like the fins. As you get more used to them, and concentrate on the
big amplitude, slow kicks, your air consumption should go down alot. A big
kick, a long glide, and you can do what other divers can't --conserve energy
by coasting. This is one reason I like ultra streamlined gear like Halcyon,
so I can get a really good glide between kicks.

You know Dan, the reason you like free diving fins isn't just their surface
area. Its the same reason I like Original Force Fins when diving in a
current.

When someone kicks a pair of free diving fins, the angle of the blade
relevant to the direction of travel stays oriented to best take advantage of
the water flow. Their simply too long to pull perpendicular to the direction
of travel. The design of the Force Fin blade, as well as the design of the
other fins in our portfolio that you do like keep properly oriented to your
direction of travel too.

Susanne,
After trying your more advanced Force Fins, I have come to the realization
that they represent an entirely different way to push yourself through the
water. For many people, this may be a better way than with traditional fins.
For the subset of the population which is highly fit, and who can quickly
feel comfortable with the large amplitude, slow frequency kick style you use
with freediving fins, I still believe this is the best way to go---and a way
Force fin can evolve into, with its own freediving fin, as Bob has
demonstrated with prototypes.
For people who do not find it natural to use a large amplitude, slow
frequency kicks, and prefer instead a more rapid, low amplitude flutter, the
Force fin offerings, in their advanced fins, are outstanding.

I still hate the idea of the original Force fin, because it caters to a
person with such low muscle power and low fitness---by way of its
requirement for very rapid turnover and very little thrust result--but with
almost no torque required----this is a fin ideal for a 400 pound person, who
might be better off watching TV and eating Pizza and ice cream with Coca
cola. Maybe I am exagerating too much here, but I still see this as a crutch
for someone who should become more fit, rather than re-shape the world into
their own conception  of lazyness. Your other models begin to raise the
fitness bar with their capabilities, allowing normal divers to match their
fitness with a model ideal for them by Force fin.  No one else in the Fin
world, other than a few tiny freedive fin companies the average consumer
will never hear of or find,  have been smart enough to do that, and for
this, I commend you guys.

As to the perpendicular to current issue....... it sounds good, but the
"high end" freedive fin   "alternative" benefit, is that you can go through
the dive making one big push, followed by a huge long glide, then one more
big push, then one more long glide----a streamlined diver can have awesome
air consumption from this type of mechanics, since it allows a very low
heart rate at an averaged speed normal to most divers---this the result of
much gliding. I could keep my heart rate in the low 60's, with most divers
at their comfortable pace, using a fin like the Omer C4.  And there are some
divers I could dive with where I could stay in the high 50's. My resting
pulse is 48 to 50bpm, and my max heart rate is 204, aerobic zone is 157 to
188, just to put this low heart rate at diving pace in perspective. The low
heart rate from very low kick turnover, translates into very slow breathing
and very low air consumption. If I use trashed fins, like my old pair of
Omer Tuna Comps, the efficiency is so low that they are not terribly
competitive in this example. Their is a requirement that the fin retains its
optimal flex charicteristics, and can "return" power optimally after each
kick.
This is the basic concept freedivers enjoy to perform breath hold dives--the
kick and glide, utilizing a very low heart rate ( which allows long periods
between breaths if required by a freediver--for the scuba diver, it just
allows a much smaller demand for air).

I am still anxious to try the  Force Fin freediving fin---whenever they
finally become available !!!!

Dan,

Phew! How do you get those measurements at depth? And I said that I found
free diving fins elegant.

When this whole mess landed me in the hospital, I maintained an oxygen
absorption level of 98%. That means my cardiovascular system is in very good
shape. My personal preference is the Original Force Fin. I don't recommend
them for every customer who calls. Like you, Bob as of late is preferring
his Excellerating Force Fins.

I find the customers who are happiest scuba diving with the Original Force
Fin are either those in poor shape as you choose to pigeonhole, or those of
an elite level -- the two extremes. We make plenty of Force Fin variations
for those in between.

With respect to elite divers and swimmers, we find that they use cues other
than the resistence or drag of their fins -- your fitness workload, Dan --
as their measurement of forward momentum. An elite swimmer is going to feel
more comfortable with a swimmers kick. They can measure their forward
momentum or the thrust output of their fin blade by how they're moving, not
by how they are working.

I personally believe that kicking your fin should be easy. When scuba diving
there are too many other things to enjoy and consider than how to kick your
fins. A low amplitude, wide stride kick is an adaptation of your kick for
your fins, just as a frog kick is an adaptation for optimizing Jet Fins.
Sure you can be very efficient once adapted, but why suggest that everyone
go through the process?

Love ya,

Force Fins were great when I lived in St Thomas, because they were better
than bare feet for doing boat surveys, replacing zinks, etc,
and you could walk on the dock with them on and go from boat to boat.

Hi Suzanne,
Careful, someone will repeat this as saying you like freediving fins :-
As to the measurement of HR, I have a Polar 720i heart rate
monitor---awesome gadget, I bought it for cycling, but its good to 60 feet
deep and will download to my PC afterward.

Ahhh, lets use the experience of forward speed through the water--as
measured by how fast the bottom goes by....that does not make me sound so
myopic ;-)

And in my last post, I did allude to this---I am aware some people will be
comfortable with the big amplitude kicks, and some will not.

My take on this is very different.  The slower, longer kick is the standard
which most of us learned long before fins were particularly efficient.
Anything else, including a more rapid kick characteristic of the split fins
and, apparently the Force Fins, is an adaptation to the fin's different
functional aspects.  In my personal opinion, your question below is a good
one, but applied to the wrong fin.

> Sure you can be very efficient once adapted, but why suggest that everyone

Regarding Jet Fins, the frog kick is not an adaptation of otimizing them.
It is an adaptation for preventing them, or any other fin, from silting out
confined spaces.  The frog kick is not an optimal method of propulsion
except where silt is an issue.

Lee
Force Fin - 15 Nov 2003 19:30 GMT
Lee,

Kicks taught in the industry have always evolved relative to the fins sold
in the industry. A low amplitude, wide stride kick was the standard kick
taught when we first started our business in 1983. I think the best sellers
then were the Jet, Rocket or Power Plana. With these boards you have to use
a low amplitude, wide stride kick or oxygen deplete. The same is true with
free diving fins, but they keep a better angle relative to your direction of
travel than these other fins when you use this kick.

Most fins, and I'm talking fins in general, are pretty flexible nowadays.
As such, the kick can be streamlined without oxygen depleting unless you
have to really go for it. I think that has led to a practice to let divers
kick more comfortably during instruction and concentrate more on other
things, unless you have a student that is having problems kicking in
general. Most divers are flutter kicking, or close to it these days.

The exception is us old salts that learned to dive when the Jet, Rocket,
Plana Power or even UDT Duck foot was the industry standard, or a few years
thereafter while the instruction caught up with fin design changes. We're a
minority now. And, if you are an old salt, you are comfortable enough in the
water to make changes and adaptations if you care to take the time to make
your diving easier.

Likewise, most of those involved in the cave diving standardization process
were diving Jet Fins or various clones that were popular at that time.  As
such, they developed kicking techniques that limited silting when using
those fins. Isn't the best fin for cave diving the Jet Fin? Cave divers are
an influential market elite, so manufacturers design fins to work well with
the frog kick. Its a kick loop.

With different fins, there are different techniques that may work as well or
maybe even better, if those fins are used instead. Does that mean you
shouldn't frog kick with Jet Fins. Of course not. It just means that being
open minded and letting technique expand with design evolution isn't wrong
either.

We are not going to go into the "swim against current" issue again, are we?

Boys and girls, listen: Fins do not care whether there is a current or no.
They do not know!
   If  your fin(s) push you through the water at, say, 3 knots in still
water (assuming the same type of leg motion throughout) they are still going
to push you through the water at 3 knots if there is a current running. But,
if you are heading straight into a 3 knot current your headway will be zero!
   You/yourself/your body are still moving through the water at 3 knots.
The idea that some type of fins suddenly forget how to work when the ocean
is moving is absurd...the fins do not know.
   Notice here how I am not mentioning any type of fin over another? If a
certain type of fin works for you then by all means I think you should
obtain it and use it. Some types of fins work well, but they require a
tri-athletes strength and endurance to keep them up into any type of speed
range, plus they are as comfortable as hiking uphill in wooden clogs. Other
types of fins give good speed and require less effort, allowing you to use
them at higher speeds for longer distances. And they are comfy to wear. And
just like underwear not everyone agrees on the same type or brand. (yes,
there are people out there that insist a fin be uncomfortable or high-effort
to be considered a manly fin. Just like my grandmother insisted that nothing
that is good for you can taste good.*)
   FINS DO NOT SUDDENLY CHANGE THE WAY THEY WORK IF THE WATER IS IN MOTION.
THERE IS NO EASTER BUNNY.

R Beard,
There actually "is" an issue with side currents, if the fins in question are
of the Split Fin variety. While the split fins can achieve decent speed in a
straight line--in either no current or  straight against a good current,
this is not always enough.

Here in South Florida, we have long reef lines which parallel the shore,
about 2 to 3 miles out. This goes on for about 50 miles or so. The reef
crown is less than 100 yards across on much of this--in some places wider,
in some narrower.  A typical dive profile could be dropping on the offshore
facing side of the reef, where it may be 90 feet deep, doing a drift along
it for 5 to 10 minutes or so, then coming up to the crown at 37 to 50 feet,
crossing it and then spending another 30 to 40 minutes on the inshore facing
reef  --which will vary from 45 to 60 feet deep in the sand at the bottom of
the ledge.

In crossing the reef, split fin wearers typically have problems keeping up
with divers wearing traditional fins, particularly on days when the current
is really flying.  My girlfriend and I have had to literally drag a couple
of split fin wearing divers across the reef, in order for them to make the
crossing--this same couple had been fine on dives like this,  prior to their
unfortunate purchase of their fancy new split fins. My girlfriend was able
to pull her huge dual strobe camera AND the female diver from this couple,
all the way across the reef, using her freedive fins--the woman she pulled
just could not make headway on her own.  I had no camera to push, and found
no difficulty in dragging the woman's husband across.

There are also days when the current does not just run with the reef, but
heads out at a 45 degree angle to it, forcing the divers to deal with a
constant side current. This is the place split fin wearers suffer, and this
idea is part of what I was referring to in the earlier post.

Their is actually some physics to this, and the place I originally heard it
was from Bob Evans of Force fins. Since I have seen this empirically
demonstrated time and time again, the explanation Bob has would seem to be
born out. Hopefully he will see this thread and share it with the NG.

Dan Volker

You obviously missed out on the split fin thread a few weeks ago - I
went into this concept and explained the science behind why you are
wrong.  Logic would make it seem like your argument is correct, however
fluid dynamics are not relativistic - meaning that water moving at 3
knots will have certain physical properties regardless of whether you
are moving with the current (i.e. you "see" 0 knots), moving against the
current, or moving perpendicular to the current.  The most important of
these is the Reynolds number.

The Reynolds number is a number you can calculate based on certain
properties of a fluid - notably the fluids viscosity (resistance to
flow), temperature, and most importantly, velocity.  As the velocity of
the fluid (in our case water) increases so does the Reynolds number.
Once the Reynolds number becomes equal to or greater than 30 water flow
will become turbulent - and turbulent flow kills the efficiency of splits.

For splits to work properly you need what is termed laminar flow -
smooth, non-turbuent flow of the water.  As you kick split fins you'll
get water flowing faster over one face of the fin then the other.  This
creates lower pressure on one side of the fin then the other
(differential pressure), providing thrust.  This is the same concept
that airplane wings use to fly.  As soon as turbulence forms you loose
the smooth flow, you loose differential pressure, and so you loose
thrust.  That's the catch - when you kick you make the water move, which
will increase the Reynolds number of the water surrounding your fin.  If
the Reynolds number increases past 30 you'll generate turbulence and you
will not generate thrust.  Now if you are in resting water the water has
a reynolds number of zero, but water moving at 3 knots has a Reynolds
number approaching 12 - meaning in your example of a three knot current
your fins have, in essence, already "lost" about 1/2 of their potential
thrust.

So, in fact, you fins do "know" if the water around them is moving.

If you'd like to know more (or don't trust me) you can read up on these
things yourself - fluid dynamics is the area of physics which rule fin
function.  But that's a large area, the main things you want to read on
are: differential pressure (or airplane wings), laminar flow, turbulent
flow, and the Reynolds number.

Science is a bitch...

Critical Reynolds number is usually quoted as 2000.  Where did the 30
come from?

Reynolds number is the product of velocity and characteristic size,
divided by kinematic viscosity.  Unfortunately the kinematic viscosity
of water is about 1.E-6 m^2/s.  So if we assume a velocity of only 1 m/s
and a characteristic length of 0.1 m (representing fin width), this
gives a Reynolds number around 100,000.  It's not clear to me how any
fin could operate in a laminar flow regime.

Characteristic length should be the thickness of the fin; analogous to
flow around wings, spheres, cylinders, you name it.

However, even at a fin thickness of 1 mm (too thin) would give a Re=1000.
That's still not laminar flow; at most the transition zone between
laminar and turbulent.
Force Fin - 16 Nov 2003 01:03 GMT
If I'm not mistaken, the transition happens at about 11" or a couple of
inches forward of the foot pocket on most fins. Just where you see it.

Convention in my field (immunology).  Because blood flow tends to have
very high reynolds numbers associated with it it's become common in my
field to talk about these things scaled down by a factor of ten (i.e. 30
= 3000).  I have no idea why we do this - it's been going on since
before I was born, ad causes no end of headaches when we want things
like software designed, but it's the way we do things.  I approximated
the number of 30 (3000) to factor in the effects of solutes and
particulate in sea water.

I'm just quoting what I've read about splits fins - which supposedly
work more like an airplane wing then a conventional fin (which functions
via displacement).  In order for a wing to work with any degree of
efficiency it must have laminar (or at least minimal turbulence) over
the wing surface.  Perhaps the answer to your question lies in boundary
effects - Im not sure about the "real" world, but in blood flow boundary
effects play a huge role in mediating how blood flows - including
allowing smooth flow where, in theory, it should be completely
turbulent.  Of course the cross section of a blood vesicle is tiny, the
ones I usually look at are in the range of 10-50um, so these effects may
have minimal impact on a fins function.

Bryan,

According to the marketing splits act like an airplane wing. In practice,
turbulence occurs when the inner flaps transition between opened up (when
you are kicking forward) and opened down (when you are pulling your leg
back), with the more flexible models (Apollo Biofin, for example).

The stiffer splits (Atomic Aquatic, for example) don't open down. They act
more like a traditional fin when you pull your leg back up. Some of the
turbulence is released, so it occurs about half way down the blade, instead
of just forward of the foot pocket as is the case with traditional fins.

Not sure what TUSA was up to curving the fins downward. It moves the
turbulence right back to just past the foot pocket and the curve. The
turbulence is so dramatic, they can suck off your foot backwards if you kick
real hard.

Scubapro lost the effect by releasing the flow of water through the vents,
much of it flows away from the blade instead of down toward the trailing
edge, much as it does when you kick hard and open any of them wide. Scubapro
are masters at marketing though. The kept a consistent image with the Jet
Fin.

Don't get me wrong. They all work, but they are generating turbulence
consistent with your math.

To keep things simple, I'm talking straight line course. When Bob gets back
from the Dive Show in Birmingham, UK, we'll see if he'll volunteer what goes
on with fins confronting sideways flow.

Rodale's dropped off my sub list long ago, before the surface of the
Earth had cooled.  Immersed, Diver, and Dive Training are worth
reading, anyway.
Just tried a pair of Force Fin Pros on a trip to Cayman Brac last
week.  Liked them a lot for boat dives--they were great, very
controllable for pottering about the reefs, and exploring the
Tibbetts, but I finally had to buy a pair of long fins locally to do
the shore dives I wanted (they were Beuchat Activas, which I found
acceptable).   The Force Fins just weren't moving me through the water
well enough for those 300 yard surface swims out to the wall,
especially since the weather was crap for the whole two damned weeks
and there were honkin' big waves (by CB standards) on both sides of
the island...viz was lousy too, but I'm not here to whine about my
trip (well, maybe a bit).
I found it interesting that my SAC stayed steady at around 0.5 for
both fins.  I really expected to see a difference one way or the
other.
Anyway, if Rodales trashed Force Fins, I must politely disagree with
them, even though it's not the rec.scuba way.

Toren,

Long fins do surface swim well. When you get a chance you might want to
try a pair of Excellerating Force Fins for your long surface swims. The
blade is narrow near the foot, so it easily holds in the water. It
widens to a flexible trailing edge for maximum thrust. With tapered side
edges and vortex generators to prevent turbulent flow as the water moves
down the blade.

Rodale didn't exactly trash Force Fins. It was a lot more complex.

In short, they made statements we felt were defamatory. They had no data
or documentation to support results of fin tests on our Force Fin or
Extra Force Fin products. They used our "Force Fin" trademark on their
website to redirect readers to web pages soliciting licenses to Nature's
Wings Patents; pages that said nothing about Force Fin products.
Nature's Wings paid their ScubaLab Director and author of the articles
for four years of fin testing. Rodale was holding out to the public that
they were objective and unbiased. They offered a $10,000 award to anyone
who could find any editorial that contains lies, misrepresentations or
other distortions as proof of bias. We submitted our proof and they
refused to pay.

The link and articles on the Force Fin products are no longer on their
website. A $9,000 settlement was reached on the $10,000 award.

The story was covered by our local Santa Barbara News Press. It was
picked up by CDNN who posted it here and started this thread.

Bob's putting it through the paces a bit longer. He's exclusively supplying
Jean Michel Cousteau and his team of divers at Oceans Futures Society. Once
we've got enough mileage in enough conditions, we'll release it in general.

We'll be auctioning pairs that have been on various expeditions signed by
the expedition members, including Jean Michel Cousteau and Bob Evans as a

Hi Susanne,
These are the ones....I got to try a prototype of these...I liked them, but
I need a pair with longer and stiffer blades. Even at the max setting they
were too soft for someone who is used to competition level freedive fins (
but of course, this would "not"  be 99% of scuba divers ;-)
I've used Esclapez Blue fins before, which used to be their softest
model--the one used by freedivers planning to be in the water for 8 hours
straight for a long contest----since I don't generally dive more than 3
hours, the spaghetti feel of the blue fins bothered me. Esclapez also made
the green fin ( quite a bit stiffer), and the black fins ( a great deal
stiffer). The greens were aimed more at deeper freediving for a shorter
duration--like 4 hours, and the blacks for 100 foot deep drops for maybe an
hour or 2. The black fins came closest for me, in providing me a comfortable
"push" platform, which I felt great using for up to 3 hours ( actual
duration of each fin use  is still individualized to each person).
If a person matched their own muscle and aerobic fitness, with a model too
stiff for them, then cramping prior to the desired max duration would
probably occur.

Freedive fin companies have used this "mission oriented" model selection for
many years now..They don't say this model is for weak divers, and this one
is for highly fit divers--at least not for their standard models, of which
their will typically be 2 to 4 stiffness choices ( and of course, the
stiffer ones will be harder to load with muscle effort, and will then
"unload" much more forcefully, pushing the freediver faster and further
through the water from each single kick).  The freedive manufacturers that
offer elite competition fins, "will" sometimes suggest that their top elite
fins "are only" for elite level athletes, as these will be tuned for someone
doing 1 hour or less duration, very deep freediving, and this will be aimed
at people who have adapted to very rigorous aerobic and weight based
training---or just a huge amount of time in the water kicking freedive fins
every day :-)

The interesting thing is that companies like Scubapro, Mares, and the other
large scuba fin manufacturers, ignore the REALITY that this categorization
used by the freedive mfg's for duration use, is IDEAL for scuba use, as it
is an optimal way to help a person match their fitness with the flex
characteristics of a fin.   Bob Evans and Force Fin have actually done this,
but kept  the fitness characterizations "out of" the marketing, instead
positioning the progressively more aggressive fins as being for more
"advanced" divers.
Perhaps you guys are right, in that the scuba world is offended by fitness,
or suggestions that a diver should have it--and with this in mind, linking
the potential of the fins to a person who spends more time diving, might
well be the "safest" way to market this range of potentials. Personally, I
think you could let the dive shops in on this, and they could help "push"
the stiffer, more aggressive models on the people who are clearly more fit.
This is something I have NOT seen at local dive shops. And the complication
for this of course, is that a huge percentage of dive shops, are populated
with ego-challenged, doughnut eating divemaster and instructor types---and
these people combine poor fitness with macho mentalities---they would find
it tough to tell a diver that they should try an advanced fin if it is "too
advanced" for the divemaster/instructor. And the whole system starts to
break down, as the poor fitness levels and big egos destroy good advice.
Luckily their are good shops, good instructors, and even good coffee servers
:-) , but there are not enough of them ;-)

The new fin you guys have adds a particularly cool dimension, in that it
allows a diver to actually increase or decrease the stiffness and push level
per kick, while in the water on a dive. As great as this feature is, for the
reasons talked about above, you really do need a version of this fin which
starts at the  stiffest level of your existing fin, and goes far beyond.
This would be needed at the very least, for the elite competitive
freediving community. Certainly there are scuba divers which could enjoy
this as well.
If you guys want to be able to bump chests with the Omer C4's, or equivalent
state of the art freedive fins, then this is the path I'm hoping you will
take. Please relay this to Bob, in a nice way :-)

The Force Fin has for many, many years been offered in different durometers,
or stiffness, Original, Pro and Tan Delta.  With some of Bob Evans' new
fins, that Dan has tried, you can change the stiffness and/or blade dynamics
of the same blade while you are underwater and underway.

Bob and Mary,
You've brought up a point that I should explain more about---the issue about
good and bad dive shops.
Just so people know where I am coming from, in comments like the one I made
and that  you took issue with, let me explain this.

In South Florida, we have a huge number of dive shops---I don't know where
you guys are from, but we probably have as many dive shops as you do Burger
Kings.  Most of the dive shops are forced to offer $99 instruction in their
window, and to use automobile industry style advertising ( i.e., misleading)
in order to get divers to visit---divers with all the choices in shops, and
all the SALES advertised, are under a powerful motivating force to have zero
loyalty to a local shop. This would be about the money.

But then, you look at the differences between the shops, and there are a few
shops who really do have good divers working at them, and these good divers
want to share their experiences with the people coming into the shops. And
when you find  a shop like this, they are worth paying a little more
sometimes, because they won't push the wrong gear to you, just so that the
shop can make a buck. The shops like this can do a great deal to help you in
finding the gear that is best for you ( as opposed to the gear that is best
for the shop to sell).

Anyway, you have huge numbers of the first example--the bad shops, and much
smaller numbers of the good shops.

If you ARE a good shop, then my comments should help you, because I want
divers to realize what a good resource "good shops" are, and to have some
loyalty to them---going with really good advice over trying to save a few
cents ( and potentially wasting several hundred dollars or more on the wrong
gear).

Brand new divers are often completely unaware of the degree of bad advice,
coming out of the Bad Shops.  They need to hear the real story from the
people they meet who have been diving long enough to distinguish the
difference. And even divers who have been diving for several years, may need
help finding their first "good shop", because they might never have
accidentally visited one, due to the large numbers of bad ones in their
vicinity.

Maybe we should start a thread on all the good things a shop should be known
for, and all the bad things you can see in some shops--that they should be
"called on" :-)

Regards,
Dan V

This is hugely "worker" related. There have been guys and girls working in
shops, throughout the last 15 years, that I have seen make the shops that
they worked in great shops--in the sense we are now talking about.  There
was a time that Force E on Blue Heron near the bridge was good, but not
having been there in the last 2 years, I would not have any "expectations"
above the average for it today.

Brownies Southport, about 3 years ago, had some good people working in it,
and they had some great equipment--and they would even let people demo
gear--this made them a great shop....but the people I am talking about are
not there now, and I have no idea what the caliber of present workers there
now would be.

I could point out BAD shops much more easily. SunSports on Forest Hills blvd
in West Palm jumps to mind immediately.

Lee, since I have not had to buy much in the way of gear for quite some time
now, I really can't say who is working where, and which shops are good
because of this. But this would be an excellent thread----

-----   The search for the Best Dive Shop in South Florida.
Criteria: Best personnel in shop ( good divers who have knowledge and desire
to "HELP" customers over just making sales)
               Best program for allowing customers to gain familiarity with
gear--Demo Program type of approach
               Best Instructors
               Best shop at matching "Divers" to "Dive Boats"     (
advanced divers never sent to boat full of novices, rambos sent to boats
with other Rambos, Photographers sent to boats with other Photogs, i.e.,
some sense in putting people together)
               Best Equipment selection ( still requires being good at
matching gear to each individual and caring about this).

Lee, what do you think should be added to this ?

None of the Force E shops are particularly convenient for me.  I've found a
couple of employees in them that I liked, but more than I didn't.  I'm not
real fond of the idea of having a repair shop at a remote location, but it
makes sense for them.  I kind of like to know and speak with my techs first
hand.  On the other hand, they did as good a job on my regulators as anybody
has and did both my USD Monitor I computers cheaper than anybody else I
could find.  I'm a bit biased in favor of chain since I know Skip
personally.  I used to do QA for him.  I'd go into various shops looking for
just the kinds of things you mention.  Sometimes I found them, sometimes I
didn't.  Skip heard about it either way.  In return, I got a discount on
whatever I purchased, but the biggest incentive was helping improve the
shops in the area.  Any shop that cares enough to implement such a program,
is more likely to be the kind of shop we all like to find.  Force E is near
the top of my list even though I don't visit them often . . . or maybe
because I don't visit them often.  It's easier to maintain quality once it's
in place, but even then, it's not automatic.

The Diver's Den that used to be on University, just a bit south of 595 was
one of my favorite stores.  The people there were the kind you like to find,
experienced, knowledgeable and honest.  They're the ones that turned me away
from some much more expensive fins and on to Mares Avante fins.  Like
everybody else, they had some good deals and some not so good ones.  I
bought three complete regulators and assorted attachments from them without
problem or complaint.  Theresa closed that shop long ago and Smitty, the
shop salesman I liked most, took up selling BMW cars.  Go figure.  Maybe
there is an honest car salesman in the world after all.  I don't use the
shop that took over the location, Diver's Cove, because I know the story
behind the transition and do not think that they treated Theresa as honestly
as I would have liked.  Dishonesty will kill my business faster than
anything else and, until I find out differently from a reliable source, my
opinion is that the new owner was dishonest.

Brownies still has some good people, but they're they're hardly likely to
direct anybody away from anything with the name Halcyon on it and they're
more than a little biased toward GUE.  The link between the shop, Halcyon,
EE and GUE is just a bit too close for me to be comfortable recommending
them to somebody that does not know exactly what they want and why.  I'm
also not fond of "fair trade pricing", something that they are more likely
to follow than unaffiliated shops.  More importantly to my business, their
fill and service prices are high and the last few fills they did for me were
not even close to what they were supposed to be.  I'm not sure who was
responsible.  I've heard that there's one person there that seems to believe
he knows how to do partial pressure fills that, in fact, does not, but I
don't have a name to tie to the problem.  I'm reasonably sure it's not any
of those I routinely talk with.  Regardless, fills that are significantly
off, are not acceptable from a shop so technical in focus.

Mark, at Fill Express, is currently on my list of good guys.  So far, he's
not tried to direct me to anything in particular and his fills are spot on
and quite reasonably priced.  I can thank Bullshark for turning me on to
this operation and they get as much support as I can give them.  I want this
shop to do well.  For now, it's right on the top of my list.  I've never
felt pressured and and information I get there has always left me feeling
confident that it was good and unbiased.

I buy quite a bit of my stuff from Diver's Outlet.  I used to visit their
shop in Florida City on each trip to the Keys.  I'm more likely to shop at
their Sawgrass store these days.  I like the people and I like the prices.
One of the things I like the most, may make them less desirable for some.
They don't know as much about diving as people in most other shops I've
frequented, but they have always been honest about it.  They'll give me the
line the manufacturers give them, but have never tried to convince me they
knew something they didn't.  Honesty will always rank higher with me than
experience, but the two are close to equally important when I'm trying to
expand my knowledge into new areas.

I'm in much the same position.  I still buy stuff once in a while, but I'm
past the point where I do much more than price shop.  Most of the time, I
know what I want and, for some things, know where I'll buy it.  Some of the
time, I pay higher prices for the convenience of going home with what I
want, sometimes, I pay more attention to prices.  It just depends on my mood
at the time.

By your own admission, Susanne, it was not an "award". The $9,000, which was
$1,000 less than you sued for on that complaint, was the award.

And you failed on four other major points. Why don't you admit that you filed a

Force Fin - 21 Nov 2003 03:21 GMT
Your interpretation is wrong. The case was never heard on its merits. The
settlement was negotiated in Court, not to avoid Court. Here are the facts.
Judge for yourself.

On October 15, 2001, Bob Evans Designs, Inc., makers of the Force Fin, filed
a
Complaint against Rodale, Inc., Publishers of Rodale's Scuba Diving
Magazine,
alleging Defamation, Trade Libel, Intentional Interference of Prospective
Business Advantage, Unfair Competition and Breach of Contract.

A summary of facts supporting the allegations are as follows:

In articles published in Rodale's Scuba Diving statements were made implying
that Bob Evans Designs, Inc. was doing something wrong in marketing their
Split Foil Force Fin without license from Nature's Wings. Rodale had been
previously notified by Bob Evans Designs, Inc. that the technology and
design
of its Split Foil Force Fin are found in its own patents that predate the
others.

Rodale, Inc. reported tests of Force Fin products as independent, objective
and unbiased, when in fact no data or documentation existed to support
results
of fin tests on the Force Fin or Extra Force Fin. Nature's Wings paid the
then-Director of Rodale's ScubaLab and author of the articles for
approximately four years of fin tests. Some of the tests were developed by
Nature's Wings.

Rodale, Inc. used the  "Force Fin" trademark on their website to redirect
readers to web pages soliciting licenses to Nature's Wings patents; pages
that
said nothing about Force Fin products.

Rodale, Inc. offered a $10,000 award to anyone who could find any editorial
that contains lies, misrepresentations or other distortions as proof of
bias.
Bob Evans Designs, Inc. submitted their proof. Rodale, Inc. refused to pay.

Statements surrounding the settlement circulated by Rodale leave out the
fact
that the case was never heard on its merits. On February 14, 2003, the
Honorable John F. Walter, United States District Judge granted Rodale's
Motion
for Summary Judgment finding  "that Bob Evans' [first four causes of action]
all arise out of alledgedly defamatory statements made by Rodale and
distributed to the public over one year prior to Bob Evans filing its
complaint,... and are barred by California CCP $340(c)'s one year statute of
limitations."

In September 2003, members of the dive industry rallied to the support of
Bob
Evans Designs, Inc. and emailed their demand that Rodale remove the
allegedly
unfair link.  Rodale responded by removing the link and all articles
referencing Force Fin products.

On October 13, 2003, before the Honorable Thomas P. Anderle, Judge, Superior
Court of the County of Santa Barbara, a Court negotiated settlement was
reached. In attendance for Bob Evans Designs, Inc. were its Officers, Robert
B. Evans and Susanne E. Chess. In attendance for Rodale, Inc. was its
Advertising Director, Debbie Edwards. Attorneys for each party were also
present. A $9,000 settlement
was reached on the $10,000 award.

Statements made by Dane Farnum, Publisher, Rodale's Scuba Diving regarding
the
suit conclude with the statement that  "Rodale's Scuba Diving will continue
to
publish the only comparative scuba equipment evaluations available in the
United States." The evaluations are not characterized as  "independent",
"objective" or  "unbiased".

Truth prevailed and that's a win for everyone.

That's a lot of stuff to analyze.  It is tough to separate out what
was said by the "court" and what is being said by you or other Force
representatives, but at the end you wrote...

...."Statements made by Dane Farnum, Publisher, Rodale's Scuba Diving

to

The statement above appears to be of your own words, not that of a
finding of the court.  Did the court find at any point that Rodale's
evaluations were "biased", "non-objective" and "dependant"- whatever
that means.  Apparently the court did find Rodale's didn't submit
evidence they weren't (if I read your comments correctly), but the
court didn't state that they were.

The only things I could find as aggrieveing towards Force in your
statement below is their use of the "allegedly unfair" link (which
indeed does sound unfair), which they did later remove, and the
comment about the marketing of the Split Foil Force.

I haven't read the huge 120+ response long thread below, but I have
seen this and threads with someone with apparent links to Force
involved on several other message boards.  Sounds like sour grapes to
me.

Let's face it.  I read the initial Rodale's report on split fins, they
reported at the time they had been trying to get Force fins submitted
for reviews for years, and only bought them after Apollo presented a
pair of their own fins for review and tests.  Force fins apparently
tested superior to all fins in the test, except the split fins from
Apollo.  The market jumped for those which placed at the top of
Rodale's test results...not the one which would have likely topped the
test in previous years if they had only submitted their product for
tests... Opportunites lost, perhaps Force would have cleaned up if
only they had participated willingly in previous years.

The problem is that you can't really have true objectivity when you
insist that vendors donate their products for review:  this element
alone creates a source of a bias (BTW, hadn't ScubaPro also been a
'decliner' for years?).

Afterall, if every Tom, Dick and Harry with a webpage (a public presence
as an independent, unbiased evaluator), the world's manufacturers would
clearly go out of business providing free 'evaluation' goods to all of
them, instead of making each of these businesses pay their own way.

From a business perspective, let's face realities here:  to buy a dozen
pairs of fins for a test would run less than $2K.  

That's too much for Tom/Dick/Harry, but for Rodale's, that's a drop in
the bucket:  a recent Audit Bureau of Circulations report, Rodale's
Scuba Diving had a monthly paid circulation of 186,000 and a total
readership of more than 1 million (BTW, they also report that Scuba
Diving readers have an average household income of $121,000).

So to spend an extra $2K for review gear for each and every issue works
out to a per-magazine cost of 13 cents/year, or 2 cents per reader-year.

Considering that it costs them significantly more than this to mail out
each "subscription will lapse 6 [5, 4, 3] months from now" reminder, it
is quite transparent where their business priorities really lie.

This does not wash.  The fact is, products that are highly rated by any
testing agency sell better than those that are not.  It is not at all clear
that the world's manufacturers would suffer any adverse financial effect at
all.  What is clear is that those that submitted the best products would
gain market share at the expense of those that could not, or would not
compete.  I don't see the downside.

It's not an extra $2k, is it?  Fins are one of many items the company tests.
They test BCDs, regulators, knives, lights, just about everything you can
think of related to diving and a lot of things that aren't all that closely
related.

I view it akin to paying off some gossip rag editor to either put your
client in his column... or the opposite.

No SCUBA mag (including Bin Ladinson's Blundercurrent) is above taking
advertiser's money. There are no saints.

Give gear too SDM? Then to everybody else- or be prepared to suffer the fate
offered by the "Union of SCUBA Divers" (or similar to  whatever that deal
Denninger is working on).

Until Consumer Reports recognizes what a broad market SCUBA divers
represent, and that their readership's SCUBA gear buying habits make any
sense... we're stuck with what we've got.

If left to their own devices (ie: no input from the store employee of the
store that they first stumbled into) most buyers would buy the brand with
the most L.E.D.'s or silkscreened sharks on them.

And pink snorkels.

I agree with the upsides of "free advertising", but all advertising is
subject to the laws of diminishing returns.  

My point was that if you have an oversaturation of reviewers who want a
free sample, a manufacturer is going to go broke sending out freebies
that will never generate enough return to pay for themselves.

It was $2K/month, and while I did base this based on a fin test, it
wasn't my intent to claim this as "THE" correct number.  

My point is that after you distribute whatever additional cost you want
to use across the subcription base, you end up with a small number.

A small number that is negligible, particularly in the context of the
relevent customer demographics (Rodale's Scuba Diving readers' average
household income is $120,000 per year).  When the potential individual
consumer share cost is extremely negligible and easily absorbed, all of
the publisher's excuses for not buying the gear is lame.

The *Equipment Test* issues are the highest rack sellers each year (kind of
like SI's Swim Suit issue, though obviously not at those production levels).
One would think any added cost to purchase the equipment to be tested would
be covered, at minimum, a number of times over by the uptick in rack sales
and resulting advertisement price points.

No misinterpretation. You guys sued for defamation, but gee, how much defaming
could have gone on if you waited wayyyyyyyy past the statute of limitations to
sue? How much irreparable damage to your economic benefit could there have
possibly been, unless you expect us to believe that you had to scrape enough
sales together to pay a lawyer?

In short, you decided to file a frivolous lawsuit well after the fact, and the
judge said no way Jose.

Face it, Susanne, you trolled Rodale's, and got your hand bit.

For gear, the only way you can really expect good information, is to find
shops that will let you demo gear on dives. In snow skiing, this is the way
things are done--skiers "expect" to be able to demo critical gear like boots
and skiis. But in diving, the consumer is so hoodwinked by the manufacturers
and shops, that they don't realize that they "ought" to be able to try gear
before getting stuck with it.
Find a shop carrying the gear you are interested in, and try to talk them
into a demo with credit card deposit--the credit card deposit for if you
ruin something.
And it would be worth paying significantly more than a normal "rental" fee,
for the chance to find out if some particular gear is as good as you have
heard--or as good as it "looks" :-)

Or, find a buddy who has the gear you are interested in, and see if you can
try their stuff.  Blind faith in manufacturers and dive shops has gotten us
garbage like twin jets and $80 snorkels.  Rodales just looked at the whoring
going on already, and tried to become better liars. I think they succeeded.

And there is always rec.scuba for opinions----and for something more
meaningful, try to dive with someone from rec.scuba who has the equipment
you are interested in, and who will let you try it. This might be your best
tool.

Frequently, in skiing, such demos are FREE.  You just have to be there when
the truck is full of the skis, boots, etc.

Personally, I think this is one of the best options available, particularly
if your buddy is one of the many regular divers in a group like this.  Most
of us have a range of equipment that allows us to support others without any
real burden.  Just a couple of weeks ago, a friend of mine was in town
without his equipment.  We wanted to go diving and in less than an hour, I
had put together a setup comparable to what he normally used, wing, plate,
long hose and necklaced alternate and all . . . without giving up any of the
equipment I normally use myself.

Yep.  Within all the bullshit that goes on here, there really is some good
information.  You just have to ask and be astute enough to see it when it
comes by.

Why do you think I asked about Conshelf Supremes, I've got the option of
buying a second hand Conshelf so asked.

And since a number here use it, there can't be much far wrong with them,
even if they're not exactly the ultimate best.

As usual, I agree with Dan 100%!

I have found that most shops will let a regular customer try gear. Other
shops will charge a rental fee, applicable to the gear if you buy. But
you always have to ask.

Interesting point, but when I buy ski gear, I've read up on all the new
developments and techniques in gear making, and then go to my local ski shop,
look at the lines, and decide what I'm going to try out. Then I rent those in
demo model, and try those out.

I did the same thing with dive gear. I assume I'm not alone. An LDS should let
you test out gear you want to buy, at least a demo model. But you'll note, I
still want to be informed before I go and rent.

Right, and the ski shop "demo rental" model is a good one to apply. Some shops
do this. At least in the States.

One more reason I put little faith in the Dive shops and MFG's for fair gear
reviews----since there are virtually no "Demos" going on out there, its very
hard for the dive consumer to find out when they are fed BS. In snow skiing,
if a boot manufacturer made an amazing claim, skiers would demo the product
right away, and the backlash from deceitful reviews would be nasty...

Thanks for this opportunity :-)

Split fins come to mind.....Worse still, do you remember Bondage Wings :-)
How about head mounted dive lights--they look great in an ad, but if you are
on a night dive with them, and try to get eye contact with your buddy--as
you SHOULD, you blind him :-)

Really? When I want ski gear, I go to a mountain and look for the
Manufacturer's Reps vans parked at the bottom. That way, I get to try each
ski on the same snow and day. Snow varies, dives vary- the ocean doesn't.

Irrelevant for the true point of this discussion, but maybe that's why your
skiing hasn't improved :)

I think that's relevant for a mask or fins. I'm with Volker on the fin
issue.

At this point, I can simply look at a BC and tell if it will work for me.
For a newbie, even a "test dive" wouldn't tell them a thing.

Read Rodale's for a year and you've read every article of interest
at least once.  And then it repeats.   You do much better here - at
least the FAQs are free.
