This was my experience when I switched to my harness system. By then I had a few seasons of experience so I overcame it quickly but those first few times it was quite disconcerting until I realized what I was doing to myself. Thanks for reminding me of this, I totally forgot about this happening and I don't want to put my young, already apprehensive son in this position right from the start. I'll let him make that choice later on when he's more experienced. I had to make a similar decision when it came to deciding where to take him for his open water dives. Blue Grotto or ocean boat dives.Students tend not to know how to moderate inflation on the surface and typically max out the BC.
With a jacket, this lets them ride higher and feel more secure. With a back inflate it leads to instability and pitching forward.
It's easily addressed by an instructor who knows the issue but what if he/she is dealing with another student and the back inflate student has to manage the issue on their own? Nuances of inflation and buoyancy control are easily forgotten when you feel insecure. Releasing air when you feel like you are drowning is counterintuitive and a student can easily dump too much air.
So again, I'd like to be more clear on exactly what is the real difference between a standard jacket style, back inflation, BC/W and hybrid BCD.
