Well, I did my five dives Friday, at Perch Lake, and Saturday at Lake
Wazee.  Friday night I did my underwater navigation, search and
recovery and underwater naturalist.

I found counting kicks to be far more like working out.  I think I set
a speed record on my first couple of navigation skills.  I had a hard
time not trying to kick as hard as I possibly could and I also would
exhale hard at the top of every kick, like I was doing reps in the
squat.  I have the whole explosive lifting thing so ingrained in me
that counting kicks was equal to counting reps in the gym and I wanted
to do them all that way.  But, I did the skills rather well for the
most part.  And, I mellowed out at the end.  Plus I learned that it is
better to just glance at the compass every now and again instead of
looking at it constantly.  The compass is also good for turns and it's
best to rely mostly on natural navigation.  I might also try to come
up with a way of calculating distance without counting kicks.

Search and recovery was interesting.  Again, I swam patterns and I got
to use a lift bag.  My instructor explained how to use it properly and
the things that one must look out for.  He had me get the bag buoyant
(we had about 30 pounds of weight on a weight belt as the recovery
object) and then had me release some of the air through the vent to
demonstrate just how quickly it would drop back to the bottom as it
descended.  I then lifted it and guided it up slowly to the surface
and then swam it into shore.

Then, we did the underwater naturalist.  I can see that my instructor
is really into that sort of thing.  Probably because he does that sort
of thing for a living, at least for part of his living.  I felt like I
was in a high school biology class.  He was very knowledgeable about
lake biology and especially the plant life and how exotic species
affect a lake's ecosystem.  I thought it would be kind of boring but
it was extremely informative.

So then I head down to Black River Falls to Lake Wazee for my deep
dive and the most fun dive yet, the DPV dive (give me a hell yeah!).
We went down to just below 60 feet to make it an official deep dive.
Hell, I wanted to go way deeper but I think my instructor didn't like
the 42 degree water.  I did a math problem on a slate and then we
started back up the wall.  We did our safety stop in about 15 feet of
water where a bunch of fish cribs are conveniently located.  How cool.
We seen some monster small mouth and some decent size sunnies.  We
actually did more like a 5-10 minute safety stop because the scenery
was so neat and the water was so warm at that depth.

Last but not least was the diver propulsion vehicles.  My instructor
has a pair of scuba pro DPVs that aren't sold any more due to their
price ($2000 a piece).  We whipped all over that flooded mine, zipping
through trees and along the walls.  I've got to get me one!  We did
that, put the machines up on shore and continued the dive, checking
out all the fish.
