RE: [PSUBS-MAILIST] Sonar Testing

Jay,
 
  I do not know how experienced the divers were that these guys were using, but the body was eventually found snagged in an underwater tree remnant. This would have been a serious problem for any tethered ROV or submarine as the entire lake was formed by an earthen damn without removing the wooded area where the lake itself was formed. The fish seemed to like this idea.
   Nice information to know about...This purpose would not be my idea of a reason to go diving...yuck!

David,

A practical note here.  Rescue divers if properly deployed will have a better chance in finding a body than the typical ambient or 1-atms. PSUB due to the fact that we have no navigation system.  The divers can use line searches (divers spread out along a line swimming forward) or spiral searches using a rope to insure that 120% of the area is covered.  Sidescan sonar would be the more proper resource to find a body.

Alan,
 
  I have chosen this submarine type for several reasons. First, cost. I have a very limited budget that looks to be further squeezed as time moves on. Second is simplicity. Should I make a serious flaw in calculations, exiting the thing should be much easier. And third, In this state I have yet to find what most would consider deep water. I have a very demanding public and hydrodynamics can be much more streamlined in an ambient.
  Some day I will attempt a 1ATM but not at the present time. I seem to be providing some good benefit to those who have already taken the plunge with this sonar research. This is enough to remove me from life's troubles for a spell. Books don't do it for me, I need hands on stuff.
  It took the local rescue squad five days to recover the body of a drowned man...imagine the anguish his family must have been going thru at the time...a submarine or even a small ROV could have been of great help in this case.
  Anyway, something simple, small, and easy to transport and deploy is what I am attempting to achieve. A moments silence hidden from the rest of the world in command of a submarine, even if for a short time. content and at peace and at home below the water. A dreamer come home.
