[hank pronk via Personal_Submersibles]

The altimeter reading increased by 500 feet. That is the  pressure drop I meant.

 matter of 5 min the pressure inside drops by 500 feet.  The
 pressure stays right on perfect until I go deeper.  My
 theory, the water is glacier fed, very cold at depth causing
 the temp inside the sub to drop, creating negative
 pressure.  Could that be it?  Vance, did that happen in
 the north sea?
