I bought a Jon boat to fish some the local electric motor only lakes, wanting to know, amid the myriad of options out there what’s a good lcr to get.  I don’t want to go overboard money wise and hoping to find something used.  
 

I guess I’d be best to have one where the transducer attaches to the trolling motor (will be in the front)?

Check out a Hummingbird Fishing Buddy portable depth finder.  Several different price levels, depending on what you want.  I have an old one that I keep specifically for those times when I've got to fish out of some rental Jon boat or some one else's Jon boat and they don't have a depth finder.

Thanks, my good fortune that my brother just found one cleaning out his garage!
