Fish Finder Xducer
Do I really need a through-hull xducer or will most transom mount types work through the kayak hull?

When kayak fishermen talk about 'thru-hull' they generally mean that the transducer is transmitting through the hull. I have never seen anybody use a real thru-hull transducer on a kayak. You wouldn't want the transducer hard-mounted on the underside of the hull, as it could be damaged when landing. The most common kayak mounting method is to use an adhesive to secure a transducer to the inside of the hull. This method protects the transducer and still provides acceptable sonar performance.

I just installed a Humminbird unit on my Revo. Bought the exterior mount transom type transducer and am using it inside the yak. They sell pucks but they aren't necessary as long as you mount the transducer pointed in the right direction.
The external units mounted internally are what most everybody I know use. I was told that if you get bubbles in your adhesive, it can adversely affect the performance of the transducer and give poor readings on your FF so I set up a water bath made from some closed cell foam and clamp the transducer to the mast post. I get great readings: |

Thanks for the help guys. I was able to thing the unit I wanted with the choice of xducer so I took the one that transmitts through hull. I'll let you know how it works out.

After years of re-glueing the transducer because of bubbles or poor signal I was pretty fed up with that method. I tried the water system as mentioned above and I think I may not have to fix it for a long time. I used a slice of wide pool noodle and carved out the shape of the puck, cutting a groove on each side for air and water to escape, and glued it down to the yak. Just pour in an ounce of water and put the puck in. It fits snug and tight and no bubbles because of the grooves. Crytal clear signal and maintenance free.
