RE: Depth Finder
Vexilar FL-8, I have 3 of them. One on my boat and 2 we take ice fishing. Got my first one about 15+ years ago. Works awsome and yes you can clamp it to the trolling motor, have to build a bracket though. Cant buy the fl-8 anymor but you can pick one up on ebay for probly 100$ bill.
