I now own a 14 ft john boat. I would like to use some sort of portable graph for it. I do not want to put a full size battery in boat due to weight. What are you guys using? I thought about just using my Marcum ice package but then I'd have to rig the transducer somehow so it doesn't sway. What else is out there that you guys use? Something cheap and basic. Really just want depth. thanks
