Transducer install. - Kayak Fishing Adventures on Big Water’s Edge

Lowrance has transducers that will "shoot through" a kayak hull, but they are not the ones that come with the Elite 3 and 4 fishfinders. Those transducers have to be in the water outside of the hull.

If you use the search function on this site you will find tons and tons of info!

But in a nutshell, from what I've read, if the transducer is mounted correctly, a plastic kayak hull has little appreciable effect on the ducer's function.

The ducer needs to mounted correctly though. There can be no air gaps/voids between the ducer and the kayak hull.

The glue, plumber's putty, etc, that you mention above, not only attach the ducer to the kayak hull, but also, when done correctly, completely fill the space between the ducer and the hull such that there are no air voids/bubbles/etc.
