I'm in the same boat. Been certified since '95 but only gone diving once in '99 before moving to Guam. Finally have my own gear and plan on going out a couple times a week for the next 2-3 hundred years. My wife and I took a scuba tune-up class a couple of months ago, and we just took the peak performance buoyancy class. Boy do I have a long way to go!
I'm a little confused. On the second dive, when I dumped the air in my bc and exhaled to descend, that was the last time I had air in my bc until I inflated it again upon surfacing at the end of the dive. All minor adjustments were made by breathing. If I wanted to descend or ascend more than a few few feet I would just fin there nice and lazy like. Toward the end of the dive I found that I had to exhale really hard if I wanted to drop a little bit, and and I started getting nervous that the only way to keep from rocketing to the surface was to go inverted and kick down. Didn't happen though. I even checked again after surfacing to see if I could descend on exhale and I could although I had to blow out hard to do it..
my initial weight check was with full tank so I added 5 lbs per my instructor, then after finally surfacing check it again and my instructor suggested another pound and I opted for2'just for balance sake.
After all this long winded narrative my question- is it normal to use no air in your bc submerging to surfacing? I seem to remember being told that the deeper you went, the more you would have to add air to stay neutral, then dump as you ascended ( by finning up, of course). I thought it was kinda fun making depth changes just by breathing. Am I just being a dumb newbie?
