It works very well if you are correctly weighted. However, if you are overweighted, then you wind up with too much air in your suit, possibly leading to the legs up uncontrolled ascent situation. The other issue is that it is uncomfortable the surface - especially if you are an instructor, or in some other situation that requires spending a significant of time there. The part that most people dislike is the neck squeeze.

I think the bit where I started sinking back down into the Atlantic was a bit scary. I was thinking that if ditching gear does not work, then I will hit bottom again at 100', turn over, and then be able to release the weight belt. I was also thinking that this was unlikely to work, and even if it did, was almost certain to get me to the chamber. > Did you train yourself? Mostly. Every dive I try to learn something. Think of it as putting something into a backpack. Each dive, I add something to the back pack. Then when the day comes when you need it, you have a full back pack. (Thanks to Steve Bielenda for this analogy.) Of course, I have taken a few courses over the years. I love to show my Federation for Underwater Activities in Israel/CMAS ** card. Some people are interested. Sometimes people say "Oh cool, you learnt in Israel too!", and we get talking. Sometimes newbie store types get a little uncomfortable, until I reassure them that it is a real card, and here is the PADI AOW card that I got along the way to getting this card. Who knows, one day maybe I will finish off the DM - the instructor and I only have to get out on the same boat on the same day some time. I am proud of my IANTD Nitrox card. I am prouder still of my CPR for Professional Rescuers and First Aid cards. But I do not think that any course, or any card, can do more than open the gateway for you. Most of your learning has to be in the real world, no matter what the subject. > Because you're making basic mistakes that > can kill you. Like, why are you diving with doubles with no BC?
