they wont shoot thru alum. hull. if it is fiberglass you would have to epoxy it in.
Went to Allegany St. Park Red House Lake this morning caught several gils one crappie 10.5 inches. Fishing 18' of water fish were at 8' to 14'. Used a 1/16 oz. jig and curly tail. Tried my new showdown troller and it worked great, can use transducer right thru bottom of canoe. Will work good ice fishing this coming season. I have the bigger showdown and pleased with it, it replaced my vex. which always worked good. I prefer the Showdown over the vex but that is just me.

I guess I didn't explain I was using it it a Old Town Fiberglass canoe, used it Friday just set the puck in the bottotm and shot thru no problem. Seeing it is only portable it is limited to those uses. Works good. I have a Garmin on the bigger boat.
