I'm looking for a portable Humminbird 215 fishfinder - the one with the suction cup transducer. Does anyone know of a store around the Cleveland area that might carry these? I've alread check Gander Mtn and Dick's, with no luck. I just received the non-portable one, but really don't want to mount the transducer to the boat. I'm afraid that when I beach the boat, I'll screw up the transducer. I was going to mount it to my electric trolling motor, but the mount I bought won't work.
