OK this is making more sense now. So your pinger is on a shot line and should it somehow break free, the shot is still hanging,then you could follow it as it drifts? and presumably set up your own upline/markers nearby and now the boat, the divers and pinger are all somewhat on the same page. that seems reasonable, especially if you are all scootering. Intact wrecks are nice, id like to dive more of them, but I cant afford to travel much. Most of what we have here has been wire dragged, and then depth charged to smithereens. No reels while swimming is a no brainer, i would think line and props dont mix. There was one booth at DEMA that had all the usn spec ops contract stuff, the sdv,the compass board, the underwater gps/sat nav/keyboard transmitter, and a pinger/direction finder, that was like 3k per unit and minimum order was a dozen or something. Again, if this proves viable,please let us know. regards, Al Marvelli Ingemar Lundgren wrote: > Let me clarify what i intend to use a pinger for.
