I have a pirrana max. Works great. I have used others and they worked well too.
Suggestion: Don't get fancy when mounting the transducer. Just make a small circular dam on the floor of the boat, canoe, kayak ect. The cam can be as simple as a 1/4" high wall of masking tape or caulk. Drip some water from the paddle into the dam, 1/8" deep and then place the transducer in the puddle. This works fine through plastic, fiberglass, aluminum, etc. In a powerboat, just sit the transducer in the bilge-water. For a more permanent setup, Secure a piece of 4" PVC pipe to the deck with some sort of caulk.
The only type of constuction this won't work with is some sort of double hull or balsa core hull.
