all my years of diving both civilian and military I have never heard of a diver being snatched off one by a shark. With 4 of us on the boat I see no problem finding some one to operate the vessel(s)
Looks pretty cool Charles. I'd add a GPS unit to the rig. I'm fairly confident that GPS units don't work underwater... However, if you had an antenna that was on a float that stayed above water... It'd be real easy to "mark" your waypoint when you found something you wanted to check out later.

Haven't started on it yet. It's bad you retire to have more time to dive and search and for some reason the small part time business you started several years ago takes up most of your time. This winter I seem to be spending 2 to 3 days a week in the water working on boats and the other couple of days repairing the drysuites to get back in the water. Well after the holidays things are going to change and I'm going to be doing more important things.........MDing.........diving for fun.... searching....diving for fun.....MDing.......fishing.....Diving for fun......searching you know the things guys have to do ...
I have seen some like Sea scanner (figure 14 in the plains) on ebay from time to time. I would like one with a small plexi glass windshield. Something else I was thinking of. Since boat to tow communications will be expensive I was thinking of "traffic light communications" Something a long the lines of a 3 way toggle switch water proofed ( have done several for U/W lights) Power line ran up the tow cable. On board a small panel with Red and Green lights. Diver hits switch to signal go or stop. Easy to move from boat to boat.

All Types Of Treasure Hunting
Re: Another Shipwreck search tool (revisited)
I dont think the hydrospeeder is being made anymore,thier web site is gone.right now. im just getting parts for the one im making,but im also building a ROV i have everything i need to build it,just have to find some time to put it all together,the frame is done so far,but i have a 26 foot ocean boat im working on plus a 20 foot mini Rv,the RV will come in handy for all those trips to the beaches,i will be able to stay as long as i want,in any kind of weather,even hurricanes should i paint it black or camo?
Millions of dollars of Spanish treasure await those who would dare brave the eye of the hurricane.
I think one could modify a DPV (like the one Fisheye pictured), with a quick release (similar to those used in gliders). The DPV pilot could then fly the DPV using the concept described in the documents that Charles posted. The DPV can be maneuvered in the pitch and roll axis while under tow ((similar to the two axis control system used on my Weedhopper ultralight). The only control surfaces on that are the rudder and elevator). Charles idea of some type of Christmas tree lighting system would be ideal and cost effective. This way the boat can be stopped or slowed to create some slack in the line prior to release, also keeping the recovery boat on station (this will be important to the DPV pilot). The DPV pilot just has to pull the handle to disconnect the line from the Recovery/Tow vessel to investigate any possible wreckage sighted on the bottom. This would also allow the DPV more bottom time, as you would not be using the motors and batteries until you disconnect from the tow vessel.
Now we just need to install a magnetometer under the DPV, and we can do two searches on each leg of the search grid. Should the magnetometer register a hit, the recovery vessel can come to a full stop, allowing the DPV pilot to remain tethered to the boat and attempt to pin point the source of the mag hit.
I don't see why you couldn't as long as there is no ferrous metal close for it to bang off of. There is a company (I'll see if I can find their web site again) that builds a hand held magnetometer for underwater use by diver's.
