side imaging sonar issue

If that statement about voltage is true I'm going to be pissed. They told me I could run the ff on a 10amp battery and there is no way it's holding that voltage very long. I really hate technology honestly, what a part n in the ass. I just want to fish and now I spend money on this crap and have to fiddle with it forever to try to get my worth out of it.

Thanks a lot jimmy, I'll test/try the things you say. Appreciate the info.
