Default RE: Stopped submerged and level control

It will function as a fishes swim bladder. It is partialy filled with air at neutral. To dive deflate it at any rate from slow to as guick as 3 seconds.
It would only need a open ended vertical cylinder with the cuff at the top.

NO WATER ever enters the cuff or pump. Strictly air bellows action action moving water out the bottom.
