John Smith - 03 Jul 2004 22:45 GMT I'm considering the introductory dive less at catalina island next time I'm there.
It's desribed as classroom followed with a closely supervised dive.
Any reason not to do this?

Rudy Benner - 03 Jul 2004 22:53 GMT Good idea, however, you can take the time to do a little pre-study of the principles of scuba. Any dive shop will have a book. Some knowledge of the inherit hazards cannot do you any harm.
Have fun.

I like reading. I like minimizing the unknown as much as I enjoy a good surprise now and then. In fact, I'm out the door right now to my nearest dive shop for a book.

Catalina is not the same as a nice comfy warm water tropical location.
And even THOSE "resort course" divers are exposed to hazards that they are not aware of.
The training and supervision on these dives is far below what is needed to safely dive.
To put it another way....
There were 17 deaths on Scuba in the month of June.
TWO of those were OW students doing their checkout dives. They had been through the "full" (cough) 4 days of classroom training and "full" (cough) 4 confined water dives AND 4 open water training dives. These divers were one dive away from having their OW cards and being turned loose to the world and to any cattle boat that would allow them on board. You could be buddied up with one of them.
Two didn't get that card.
Those in the same classes that did are the ones that worry me.

I was talking with some non-divers (but travellers) tonight. They have friends that got their training on the boat on the way out to the site and then went to 40' or so. Everyone (the non-divers that is) kept trying to tell me that it wasn't that big a deal because no one hat gone very deep.
By the time, our convo had concluded . . .I believe they had a more clear picture of what is what.

Of course, I survived the dives with a SEVERE case of middle ear barotrauma that took several weeks to heal.

Jammer especially is the leader of a sect of divers around here who demean and threaten with death everyone who doesn't dive *exactly* the way they do (and for everyone else listening, I mean "a.sholes," not "DIR"). No one really pays attention to them, trust me.
Have a healthy respect for the water, pay good attention during the classroom session, do a little pre-studying and you'll be all set.
Don't hold your breath, ever, even if your regulator is gone.
Don't go up too fast.
Don't go down too far
You'll be fine, and if you have fun, consider taking a real SCUBA course. It's a blast. And it's really quite easy and safe.

I don't speak for him, but I am fairly certain that Jammer doesn't give a tinkers cuss about how or what you do.
All he is trying to do (and is) is make people think for themselves.

Do not: stop breathing too long, go too deep, stay too long, ascend too fast, ascend to altitude too soon afterward. Almost everything is detail or corollary.

I don't want to get between anyone in this pissing match; I just want some replies to the idea of an introductory scuba dive while I'm in Catalina. Fortunately, I've received two contrasting views on this question.
This brief back and forth between posters has given me a pretty good idea of questions I might want to ask when I get there; before I sign on for a dive.
Finally, this is just a rhetorical question, how can I know if I'm THAT interested if I don't get my feet wet? An intro dive (short duration, shallow, and supervised) seems like a good way to find out whether I want to spend time and money on an expensive activity that I THINK I'm interested in.
Thanks for sharing your views!

> Finally, this is just a rhetorical question, how can I know if I'm THAT > interested if I don't get my feet wet? Well, for me, I was a bit like you. I'd been thinking of it for years but didn't get around to taking any lessons.
I went on a vacation to Mexico. While there, we went on a tour that included a snorkel at Shel Ha. I quickly realized that it just wasn't enough for me. Within days of my return home, I signed up for lessons. It was one of the best things I've ever done in my life.
For years prior, I was really into snow skiing. I went every weekend as soon as the season started and easily half of my annual vacations were spent skiing. Eventually, I took up sailboarding too. Once I got into that, I was hooked.
Since I've taken up diving, as much fun as my other activities were, I'm no longer interested in skiing or sailboarding.

> Thanks for sharing your views! You will certainly get "views" here and mine should be quite clear. Take a full course, you will be better able to decide if diving is right for you. What you are planning might be enough to give you a clue, but if it doesn't go well, you'll never know for sure if diving was the right choice for you.

An open water class doesn't cost that much more than the intro class.
IIRC, my resort course, 2 dives, in Grand Cayman was about $120. My OW class was $150, including equipment rental.
Time was really the only investment.

You won't know if you don't just dive in, literally. Ignore the BS that flies around this place and go enjoy your intro dive -- they're pretty safe. If the bug bites you, then get into a certification program, keep an open mind, read, learn, and ask questions -- don't take everything you're told as gospel. Above all, dive, dive, dive. Every dive is (should be) a learning experience. Enjoy yourself.

An intro dive (short duration, > shallow, and supervised) seems like a good way to find out whether I > want to spend time and money on an expensive activity that I THINK I'm > interested in. If you think you're interested then you almost certainly will be interested when you get around to it. I suppose you could go diving and decide you don't like it, but the more likely problem would be having issues with breathing while underwater rather than thinking diving is boring. You might be able to find out if you have any problems with the breathing underwater part of it for free at a dive shop that offers an introductory pool session. Assuming everything goes well, it would probably be completely safe to spend the few hundred bucks that is the upper limit for a basic OW course and mask, fins and snorkel.
My humble opinion is that resort courses are usually quite safe, but I'm sure there are rare exceptions. Arguably, the riskiest part of a resort course will be a too-rapid ascent. Sure, you might just out and out drown, but while almost nobody drowns on a resort course, almost everybody has poor buoyancy control. In nice warm tropical water, where you don't have a wetsuit, poor buoyancy probably means that you have a bit of trouble maintaining a consistent depth and swim with a bit of an up or down angle to maintain your depth. In the cold waters off of California, OTOH, you'll be wearing a nice, fat neoprene wetsuit, which will increase the buoyancy issues. At the surface it will take perhaps 15 pounds of lead to sink the suit (not counting what it takes to sink you), but at 40 feet the suit will compress, making you several pounds heavy. To overcome the heavyness (negative buoyancy) you'll have to put some air in the BC, and each time you ascend or descend a bit that air, and the bubbles in the neoprene, will expand or contract, changing your buoyancy. When you ascend to the surface that expanding air can potentially result in a runaway ascent, making a cold water resort course more likely to be dangerous than a warm water one. If that happens, the air that's inside you will also expand, and can potentially cause any of several unpleasant things to happen. That scenario is one of the reasons that instructors tend to overweight students. They'd rather have you work a bit to not sink as an alternative to a rapid ascent. As long as you vent most of the air before ascending, and stay a bit heavy, it's hard to get out of control, though you'll probably still pop up the last few feet a bit fast. As was said earlier, keep breathing so any expanding air simply goes out your mouth.
You'd almost certainly be safer taking a real OW course first, but the risks on the resort course are really quite small.

> You'd almost certainly be safer taking a real OW course first, but the > risks on the resort course are really quite small. You have touched on one of the questions I'd like an answer to. I would like to know that I can physically tolerate diving. Your suggestion to find a dive shop that offers an introductory pool session is great. I'm not sure that 8 feet is going to tell me anything about diving tolerance, since I already know I can sit at the bottom of a pool, but it's a start.
I appreciate all the safety concern expressed by this ng; I try to convey the same message re: boating.
Again, thanks to everyone for the constructive ideas.

I may not have been clear enough the first time around, depending on your meaning about sitting on the bottom. Virtually everybody is capable of physically/physiologically tolerating diving. Some portion of the people who try diving will be unable to psychologically tolerate it. Of perhaps 10 people in the pool session of the resort course that I took, one was simply unable to put his face in the water and breathe from the regulator. That only takes 6 inches of water to find out. With perseverance he could probably have managed, but with no real investment in the outcome he found it easy enough to simply make different plans for the afternoon. In my wife's OW class 1 of about 6 students hada great deal of difficulty with some of the early skills. I forget the details, but she either had trouble breathing from the reg at all or had trouble doing so with her mask off.
In my resort course the guy who bailed lost nothing but the 2 hours of classroom time, since we were at a Sandals Resort and hadn't specifically paid for the course. It would suck to lay out $100 and then find out 5 minutes into the pool session that you weren't going to get what you paid for. Assuming the outfit you want to do the resort course with runs OW classes, you could probably get a chance to just breathe from a reg when they're having one of their regular pool sessions. Alternatively, you might find a shop that is running an afternoon intro to attract students, and spend 30 minutes laying on the bottom of the pool and have to be dragged out, like one of my friends did.

This is what is generally called a "Resort Course", or a "Discover SCUBA" experience. Opinions vary as to the safety of these programs -- probably because some dive operators may use this type of course as a way to attract divers without giving proper instruction.
I have no idea what the dive operator at Cataline Island offers. I suggest you ask to meet the instructor who will conduct the class. His/her attitude is about the only way you can judget the safety of the particular offering before hand.
My wife and I started SCUBA with an excellent Resourt Course at UNEXSO in Lucaya, Freeport, Bahamas. Others have had or seen less desirable experiences.
