Why jump in the water and then float around?

[John_B]

The problem isn't what's taught in PPB, the problem is it should be taught in OW.

:applause:

I nominate Walter's post for "SB Post of the Year"! Maybe even "SB Post of the Decade"!

This is really a stretch. Let's assume I take an extra breath or two upon entry. You've popped much more than a couple extra breaths into your BC. Unless you orally inflated it, you've shortened your dive even more.

Walter, as you did not ask, how would you know? But had you, if I inflate my vest, I orally inflate it. And I take one or a partial breath on entry. However, the fact that your breathing and heart rate increase when hitting cool or cold water is a very studies fact... If you need some help finding the information..I know you will choke on this, but how about asking (rather than assuming you know everything)

How are you going to do that with an inflated BC?

This was about getting air out of your suit, so lets see.. you are vertical in the water, with only your head out..gee, the suit is completely underwater... that's how.

Last check is on the boat. I avoid having the DM touch my valve. When it does happen, I reach back and check it myself.

If you must know, he did it during the dive briefing - once, and only once. They do a strap your gear and all go at once entry off the sides.

I agree, but none of this has anything to do with inflating my BC before getting into the water.

This thread isn't about rapid descents, but if you'd like to start one, feel free.

If you want to get out of the way of others.. get down quickly... it does. After all, just going down right away does not prevent someone from jumping on you. What if they think you are headed down and just jump?

Don't do guided dives, grab your buddy and go.

Walter, you need to get out in the real world, there are a lot of places that do not allow someone to "grab your buddy and go". Actually, if one counts, would be willing to bet that there are more that don't, than do. In many countries, there are laws preventing you from doing that (are you telling people to break the law?). I know.... "Then I would not dive there".

Regarding all the terrible and bad things that can happen on the surface, they are just as rare as the ones that can happen without being on the surface on an entry. But conditions vary... boats vary... rules vary. Having one answer for every condition.. well, shows a terrible lack of proper training.

a moment an the surface can calm the nerves of a trainee just to know you are their . seniors can do hot dive if nessary and conditions are favorable

From the dive boat operator perspective, a guy jumps in and floats, signals OK then descends...all on board know he is okay. Next guy jumps in and goes right under...he may be okay, or he may be a "mud dart"...but no one on the boat know...

Your call...

Puff, I didn't assume I know everything, in fact, I threw out the possibility you orally inflate your BC (although it is pretty rare). How much does your breathing rate increase? How cold does the water have to be? How long does it last? I sincerely hope your answers show a significant difference in breathing at a relatively warm temperature and that it lasts for a fairly long time, so your point will actually be relevent. Of course, you'd also need to sit on the surface until the breathing returns to normal for it to actually matter. In my experience, people either don't sit on the surface long enough to over come this problem or the increased breathing doesn't last long enough to effect dive duration. Which is it? I'm eager to learn.

Sorry Puff, my mistake, I framed the question in a totally wrong manner, Please forgive me, I'll give it another shot. So you have air in your suit, you are floating at the surface dumping the air from the suit before you descend. How does having air in your BC assist you with this task?

If you must know, he did it during the dive briefing - once, and only once. They do a strap your gear and all go at once entry off the sides.

Sorry, but I totally missed your point, please explain.

If you want to get out of the way of others.. get down quickly... it does. After all, just going down right away does not prevent someone from jumping on you. What if they think you are headed down and just jump?

Are you under the impression you have a choice of either moving away from the entry point on the surface or descending right at the entry point? I move away from the entry point rapidly, usually underwater, but sometimes on the surface. It's not either/or.

In many countries, there are laws preventing you from doing that (are you telling people to break the law?).

What countries? I hear it is now illegal to dive without a guide in Cozumel. Please tell me of others. I don't travel as much as I'd like, but I do travel. I've never encountered a problem with avoiding guided dives, although I must admit it's been many years since I dived Cozumel. Even diving in the Soviet Union no one suggested I had to have a guide and we know how they were known for their love of freedom.

Who has suggested refusing to signal the boat crew? Last time I checked, the OK signal was forming a circle with your arm by touching your hand to the top of your head. I've never heard of an inflated BC being part of the signal.

Yeah. That's what I was thinking while I was taking it. But even if PADI deemed it too "complicated" for a brand new diver, a next best solution would be to make it mandatory for AOW, like deep diving and navigation are.

 

[Walter]

It's not too complicated, it simply takes too much time to actually teach people to dive. Take too much time and you can't certify enough of them and the profits drop.

I'm not sure that's it. People pay up front, both for books (the major dive agencies are, primarily, publishing companies) and for certification.

I think it has at least something to do with teaching people just enough to get them wanting to take more classes.

Teaching a student everything he/she needs to know takes away many residual profits.

"Sell a man a fish, and he'll soon get hungry and buy another. Teach a man to fish, and he'll never need pay you again." Or something like that.

Your point is you are either someone who is unconcerned with ethics and the truth or someone who doesn't understand how to use quotes. I assumed the second, now I fear I may have been mistaken.

Ethics? Truth? Understanding the use quotes? You sir, are very uptight. Go relax and just ignore my posts. Happy diving to you.
