Hi Everyone,

The other day I had my first diving experience, and I had some questions that I wanted to ask. I think I may have witnessed a very bad safety lapse, but I'm not sure.

I'm at a vacation spot, and I decided I wanted to try diving, so I signed up for a "discover SCUBA" session at a shop that had excellent reviews everywhere I looked. When we got into the pool I freaked out when I saw the bubbles and I started hyperventilating. I felt like I wasn't getting enough air and had to get out. After a couple more of those, I decided to skip it and let the instructor deal with the other three students. After they were done, the instructor had a nice talk with me and told me that I should at least try once more with the skills, and that if I didn't like it after that I could quit if I wanted to. I did it, felt much better, and could easily do all the skills. For some reason, the buoyancy skill came very easily to me (and I had no problems with buoyancy at all in the open water dives). After that, the instructor talked to me again and told me that the open water dives would be much easier than this, and that if I was going to have troubles it would be near the surface and that she would be there for me all the time. She was absolutely right, and the first dive was amazing--except for the fact that I inadvertently touched a fire coral.

The problem came with the second dive. It began great--we even saw a bull shark. But then, about half an hour into the dive I see the instructor graving another student and giving us the thumbs up. We want up without stopping at 15 feet at all (which we did in the first dive). After we surfaced, I saw that the instructor and the photographer were exchanging looks and trying to talk to each other. The student was asking whether she had breathed too hard, so I asked how much air she had left: 40 (I don't remember the units--is it psi or bar?). All the rest of us had more than 100. From what I gathered afterwards, the crew in the boat did not change the air tube appropriately, of perhaps at all.

I realized that this was a problem with the other student as much as with the crew and with the instructor--I checked how much air I had before getting into the water. But my questions are: was this dangerous? And how bad is it that we skipped the safety stop?
 
Safety stop is not a requirement. Skipping it for 40 bar seems a bit unnecessary but I'm not an instructor. 40 bar is roughly 580 psi so it's getting to the point of "back on the boat with 500 psi" common practice but far from dangerously low, especially for shallow depths I'd expect on a discover scuba.

I personally don't see any safety concerns at all and it actually sounds like you had a conscientious instructor who did a good job of getting you comfortable in the pool before putting you in open water, and who thumbed the dive properly when someone started to get a little low on air rather than sharing air with the newbie.

Overall, I'd classify yours as a good experience, not a bad one.
 
Thanks a lot for your reply. It was a great experience, and I definitely want to get certified now. I was just a bit concerned about what happened on the second dive, but what you say makes sense.
 
One should always check their air supply before every dive. NO question about it. As for a safety stop, on a discover scuba dive I suspect you did not go much deeper than 10 meteres and the stop was not a critical omission. Now that you have gotten the "scuba bug," I suggest you go through proper certification training, to become an active and safe diver.

How deep did you go for discover scuba? I thought it was max 40 feet. 30 minute dive at 40 feet no big deal on the safety stop. If the diver got in with low air pressure to start that would be my bigger concern. The instructor especially with discover scuba should be giving the setup a pre-dive check.
 
40 (I don't remember the units--is it psi or bar?). All the rest of us had more than 100.

The unit should be bar. If it was PSI- all of you were dangerously low.
However, 40 bar isn't quite 'freak out' range, so I'm not sure why the instructor skipped the safety stop if you had one planned.


Glad you were able to get over your pool problems and enjoy the dives. I had a pretty terrible confined water experience (though mine related more to freaking out over them taking my air away from me) but it was totally worth sticking with it to get certified and do some real dives.
 
You've described why I like Discover Scuba as an introduction to diving (as it was for me too). You had close individual attention from a perceptive instructor, and overcame beginner's nervousness and hyperventilation in shallow water, with someone right there to explain things and take time to try it again with you (since not faced with a boatfull of students and a deadline).

Sorry about the fire coral. And the second-dive early-surface order taught you the big lesson early--anyone can call off a dive at any time, for any reason--especially the instructor!! And the problem wasn't yours, your air consumption was better. Second big lesson, as stated earlier--always check your own air, breathing, and gauge before the jump-in.

Now you know you can overcome mild panic through knowledge and experience, and you want to go ahead with diving.

Many criticize Discover Scuba. I don't (unless one instructor takes on too many students, that is--mine was 1:1)
 
Thanks everyone. I will definitely get certified now. I did not know that people criticized Discover scuba (not surprising, since I didn't know anything about Scuba until very recently).

I guess I should clarify, though, that what happened was that the student got into the water with a low tank. *That* is what gave me pause.
 
It wasn't TERRIBLY low if she still had 40b after 30 minutes. I did understand that was your concern, btw.

I agree with others, not sure why you all skipped the safety stop, BUT - absolutely I would not be concerned given the depths you were diving at, for 30 minutes.

Welcome to the underwater world! Glad you stuck with it!

If the instructor was having to deal with a problem and get another student to the surface, it makes sense that she brought everyone up together and skipped the optional safety stop. She couldn't be in two places at one time.
