I am looking for a second fish finder for my boat. I have a bottomline HR master on my console. I find myself having a hard time seeing it from the back of the boat when I'm trolling. I want to get a second, less expensive finder for the back of the boat. I am looking for something that would work well in the salt, fishing from 0-250 feet. I want something "bare bones", since my other finder does everything.... Any experiences, or advise that will help me find one? Or maybe you have a used one you want to get rid of... let me know.

Thanks.
