Electronics for a Jon Boat

[Luke at Gouldsboro]

I was thinking of getting a Humminbird 140c portable fishin buddy, because its easy to take on and off, and i usually slide my boat down a sandy ramp, so a sonar mount on the bottom would probably tear off. Any suggestions for my Jon Boat electronics?

I've done it for many years and I just used a trolling motor mounted transducer with a quality sonar unit.
