Default Sonar

I know there are a ton of folks on this board that use sonar for fish finding, but I would like to find some place or sombody that wants to use other features, kind of hobbyist sonar geeks, and here's why.

The beginning of the season a friend and I were returning home down the Potomac from up near Washington DC. I was in the channel, but my friend was over near the Maryland shore, when he hit a tree trunk. Doing about 50 at the time, it totally ripped out the Bravo Drive. Needless to say, the first thing was rescue ops, and I got all onboard and his 24 foot Maxum to safety. I also marked the spot where he came to rest on my GPS. OK so I know with in about 50 yards where the outdrive is located, and the depth is only 7 feet. But, I cannot find it and it doesn't show up on my fishfinder.

That's when I became interested in hobby type side scan sonar, something I can plug into my laptop and display the results on the screen. Anybody got any ideas?

I think you efforts will be better spent getting a vidio camera on a cable. At 7' you see it on the bottom.

If you had one of the Humminbird 987 Side Imaging (i.e. Side Scan sonar) units you probably could find it on the bottom. However, they are a little pricey, not exactly 'hobby'.

I have never been in that body of water to know how turbid the water is, but maybe an underwater camera may work, also.

It is extremely muddy, so much so, that you cannot see your hand next to your knees...
I'm kinda looking for someone with a 4 foot long piece of 2 inch PVC that has a 100 dollar transducer about a foot from the front. Some stabilizing fins or a coffee can at the tail and an eye bolt for towing near the front. (Totally off the top of my head, but I'm in visionary mode today)

With today's laptop horsepower, someone ought to be able to gen up something like this?

How 'bout renting a side scan system (with either a hull mounted or pole mounted stave)? There are rental places for hydrographic survey and I am certain you rent a really nice set-up for a few days. Good luck!
