[PSUBS-MAILIST] Gamma test dive

[hank pronk via Personal_Submersibles]

Jim,
I wondered about that also, but why does it happen suddenly at a deeper depth.  Maybe a coincidence, also my co2 level was a bit on the high side, (3200ppm)  I need to get a proper O2 meter, mine crapped out.

 Hank,
 How you stopping and hovering. Are you weighted to  neutral
 buoyancy?Are you riding the bubble? Doesn't Gamma use
 forward motion and a dive plain for depth control?

  Today I dove Gamma to 95
 feet in
  Kimbasket Lake (bush Harbour)  the
 visibility was
  awful.
 
 Maybe 2 feet at best.  Big mystery though, when I dive
  to 95 feet, in a 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?  
  On a positive note, I can stop in
 the water Colum at any
  depth and hover.  I
 can surface and stop at ten feet
  and
 hover.
