I'll tell you one thing, when the hatch is closed 
  and you can't hardly hear a thing from above, it gets your attention.  
  But, when you see the water close over top of you and it continually gets 
  darker as your drifting downward, it really sets you on edge, even though you 
  know it's not THAT deep.  ;-)  The more I dove it, the more I calmed 
  down.  The first time, it was years of imagination coming to 
  REALITY.  :-)
   
  All went well.  We dove and returned several 
  times.  
  I'll have a full account of the day posted 
  soon.
   
  Thanks for all the help from the PSUBS 
  community.
