I am working with an affordable handlheld sonar device that should be able to detect lost model submarines in up to 25 feet of water. Just have begun testing so nothing conclusive yet, but will keep you up to date... Hopefully will have some data and results by December. Dr Dave

DrDave,
I am very
DrDave,
I am very interested in sonar stuff as well,
made a few hydrophones myself (with help from
the Net).
what device are you using ? a fishfinder ?
if not, would you please tell me the device (and price) ? -
I think we would all
I think we would all be interested in a way to retrieve one of our lost and expensive toys.
Further details appreciated.Comment

I used to work for
I used to work for the Minerals Management Service conducting side scan sonar surveys in the Gulf of Mexico. This equipment of course was very expensive and I realize beyond the scope of this thread. However I just wanted to comment on how detailed the capabilities were. If the side scan sonar were set to high resolution you could actually see the spokes in a bicycle tire on the sea bottom. Onetime we had to go look for a very small oil leak from a pipeline. Since the bubbles of oil rising to the surface differ in density from the water a sonar echo was possible showing the column of oil rising to the surface. This leak was very small but did produce a persistent but localized oil slick on the surface. We could pinpoint the leak with our side scan sonar and GPS equipment. This was several years ago and I'm sure that some of this technology has probably now been incorporated into less expensive fish finders? I think though that even a small side scan sonar would still be too expensive.Comment

I'm pleased to see some
I'm pleased to see some thought being applied to the problem and it is nice to know that they will be available "real soon".
However if you are "intending" to lose your submarine tomorrow have a look at my Pinger and hydrophone technology.
Available now and already with 2 submarines saved over the last 18 months!
No more dissolving sweets, aspirins and little floats!
