Ideas anyone?

[sthrngold07]

I'm going to attempt to build an underwater devise to help me in a search to find a vessel(ship?) that sank years ago.My question is this...What type of lighting will work the best for me?I'm going to have cameras inside the devise and it'll prob. be boat-towed or remote controlled possibly.The place I believe through researching,it's in a river and the depth I'm still unsure of,I'm going to say is probably 60-100ft. deep and will be murky/muddy waters.I'm just needing advise on what type lights will be the best for getting the best video-type pictures.?.I hope this makes some understandable since and ANY kinda ideas,info,and or help would be much appreciated!

Muddy, murky water? It doesn't sound like using a camera is going to be a good option unless you have some clearer water to work with. I can speak from experience with this. I live in Beaufort, SC and the rivers here are dark and murky and at best we get 1-2' of vis. Maybe a little more in the winter. I understand you are in the upstate of SC right?

I have an ROV with lights and camera and believe me, you cant see crap if there is no vis.

Would a sidescan or magnetometer not be a better choice to help pinpoint your tragets?

I agree with Robert; use remote sensing instruments to find your target, then the ROV camera to confirm.

Ahoy!!!

I remember last year when I helped Jason to replace the prop of our boat in the marina where the water is murky. The prop is what? maybe only 18 inches below the surface. I had a big a$$ flash light and still I only had about 4 inches of vis.
In my humble opinion I don't believe towing an ROV is the best way to find a target in murky, muddy waters. I would take Rob's and Don's advice and use a mag to find the target and if the target is buried under the mud which chances are then use a sub-bottom profiler to figure out how deep it is.

All the best,

Is it a large target? Wood or metal hull? Do you know the length of the ship you are looking for? Do you know if the bottom is silt? I agree with the others here and would say that if you have a large target especially metal a mag is by far your best bet. Side scan could be very effective if your looking for a large target that may be protruding from the river bed.
