Transducers are just getting bigger and bigger it seems, so this has that extra clamping power when you have something like the total scan/ 3D scan transducers from Lowrance, or even the Garmin GT52-HW. If you have a thick walled kayak or canoe, this is transducer mount for you. Even if you have a smaller transducer but you just want to be assured you can move even faster in the water; this is a fantastic option!
