I am wanting to get a fish finder for my driftboat but not sure what i should do. I dont want to mount a transducer on the bottom of the boat because it will just get tore up. The boat is aluminum so would a through hull one work or what about a suction cup one. Also have seen trolling motor mounted ones. Any help or advice on good affordable finders and how to mount it. Thanks !

I don't have one but I know one of those "Fishin Buddys" would be perfect for a DB. Portable & runs on "C" batteries. You can look sideways with those things too.
