When you are shopping around for a kayak fish finder, you will eventually think about what you are going to do about mounting your transducer.
Can You Mount A Regular Transom Mount Transducer Inside A Kayak Hull?
The answer is pretty simple – yes, you can! Since kayaks are made of plastic, the transducer is able to shoot the beam through the plastic into the water without much disturbance. So for a kayak, you don’t always need to buy a portable fish finder that comes with a suction cup transducer.
Choices in portable models are pretty limited when it comes to features and technology, so sometimes it’s better to just get a regular fish finder that you can mount onto your kayak with a little bit of DIY work.

SONAR is sound, and sound travels very nicely through solids – so plastic won’t mess up the signal.
To mount a transducer inside a kayak hull, you need to first prepare the area and clean it with some rubbing alcohol or spirit. Any dust particles or dirt that gets in may cause problems.
Once the area has been cleaned, apply a generous amount of marine goop or silicon and stick the transducer in it. Once the silicone sets, the transducer will be fixed, and you are good to go!
When applying the goop or silicone, MAKE SURE that there are no air bubbles trapped inside! SONAR waves get messed up if they hit air, so you won’t see a good return on your screen.
There are lots of variations for mounting the transducer in a kayak this way – some people like to make a “well” or a “frame” out of plastic or foam and fit the transducer in it to give it a little bit more support:
