cool_hardware52:This can occur if the diver is overweighted, and not using a crotch strap. If the diver is properly weighted he only needs a small puff of gas in the wing.
How does a small puff of gas behind your head and shoulders push you anywhere?
If over weighted the diver will often fill the wing quite full. Now there is gas down around your waist or even lower. Push you forward? You bet.
The key here, like most things in scuba, is use the gear correctly.

True, however in this case I'm not over weighted and the particular BC I'm using (seaquest Raider) was reviewed by diver magazine and the person testing it also said "I found that, however I installed the weights, I was tipped dangerously head-down under water." The full review is here http://www.divernet.com/equipment/1002divertests.htm
Now, I've noticed the same thing with even a small "puff of gas" but not to the extreme the tester in the article did and I think he might be exxagerating a wee bit. It is a great back inflate BC but this is one of the characteristics that I've noticed with this one and others I have spoken to have noticed to some degree in others they have used. I posted "may" and "might" simply to let the original poster know that he "may" experience this as well when chosing his equipment.
