I'm in my 3rd pool class of OW cert and I had trouble removing my BC underwater. I got it off of my left shoulder and reached around with my right hand to guide the tank over to my right thigh and I got off balance and almost floated to the top without my BC. I grabbed my instructor's arm for a second, then was able to regain my balance and put the BC back on at depth. But, I want to know if there is some easy trick that I am missing out. My instructor told us to hold the right shoulder strap with my left hand once it was out of the BC and I think I forgot to do that. Any hints?
