OK trying to understand the issue. 10lbs of lead puts you headdown but 11lbs does not?

First do a weight check. You do this at the end of the dive and empty the tank to 500psi.

Once you have done a weight check mess with your trim if necessary. If you are head down you can move your tank down (closer to your feet). If that is not enough you can move weight so some (maybe 3lbs) is on your feet.

You seem to have odd trim issues and strange weight issues in general. So what BC are you diving and how big is the wing? How do you know if you are trapping air as it sounds like you are at the bottom of the BC.

BTW add a few extra lbs if you think you are trapping air. A lot of new divers think that diving light is macho, but you are much better off being a couple lbs heavy. That way trapping air is not a big deal and you will get better with time.

Hi
I saw that you mentioned creative ways to trap air. I recently bought a hera bcd and I am having to put it on once in the water as we are shore diving and cant carry my tank due to a knee operation I find that while diving I feel too light when I come back to about 20ft I hear bubbles escaping not from my release valves but somewhere else. When I had 10 lbs of weight I felt like I was being tipped on my head while diving at 30 feet or more. I have never had this problem and I always return with my tank at 1400psi. I am very confused as to what I am doing wrong
If you can shed some light I would love it. I went to 11lbs and the tipping seams to have stopped. This happens when my bcd has no air in it
