Hi,
I could just be way out in left field here but it sounds like you guys might be able to straighten me out. If you get a comercially made side scan sonar, what are the limitations on depth of water it could be used in? I want to try to find a wreck in water that is only 3 to 5 feet deep. It seems that most units seem to be rated to work in a minimal depth that is deeper than that. I read on this forum yesterday where people say you drag the fish near the bottom, hence the need for an extremely durable tow fish. If this is the case:
1) Why would it matter that the water would have to have a minimal depth to work?
2) On many pictures of scans, especially on Sture's site, they appear to be pictures of wrecks that would appear to be pictures looking down from 200feet above the wreck. Why would this be if the fish is pulled near the bottom of the ocean.
I always assumed that SSS wouldn't work for my application since you wouldn't be high enough to get a picture of the complete wreck but it would sound like that isn't the case, however, it seems from what I have read so far that the depth of the water still seems to make a difference. Can someone clear this up for me, I know I'm missing something here. If I could build something that would work in 3-5ft of water, I would be much more motivated in regards to this project.
Thanks,
Charles
