Can a transducer read through the bottom of a Kevlar canoe? I have a newer garmin striker specifically.

Thanks.

My garmin striker does. I've found good results with a little putty to hold half a handful of water and the hardware - works just fine keeping it in the canoe. Great fishing finder...hope you catch a lot!

I use a small sandwich sized baggie with water and transducer in it….works well….if your hull has foam ribs or insert, transducer won’t read thru those….

Got a picture of the set-up you can share?

I've got a small homemade mount for the Garmin unit and my battery pack, but have had some troubles with various ways to mount my transducer arm.

I literally just put a little water in the bottom and it works great. ...and I mean a little water. Just scoop a little with my hand. that is it. If it falls over then I just set it back up. Shoots through with NO problem.

Hi YaMarVa,

So I looked for a pic catching a fish to see if I could find the garmin on the bottom of the canoe. No luck. I guess I don't catch enough fish!

But I did do a search on this site and found a thread with a couple of options. There is a picture of the putty mount. I also like the sandwich bag suggestion from Jatfomike and will give that a try. The other solution, explained and pictured in the thread, is to use a small piece of foam.

Hope this helps.

Yetijedi, thanks for sharing your info and the link to the other thread. This is exactly what I’m looking for.

With the putty method, are they talking plumber's putty or something else?

Probably electrical duct seal. I don't know, just a guess.

Yes, plumber's putty. Here's what I used.

I used duct seal. Just roll it out a bit then make a circle and mash the edges down to the hull. Fill with water. Works good.

When using the duct seal you don't even need the water. I ball it up to get the air pockets out then flatten it onto the bottom of the canoe. I then mash the transducer into the duct seal, embedding it without any air trapped underneath. Mine stays there for the entire trip and works fine.
The last couple seasons though I have gone to a small detachable platform that holds a rod holder, fish finder and a Scotty mount for the transducer arm. The depth and fish readings are the same but now I get water temps.

I took a 4" PVC pipe coupling and clamped a piece of plastic bag across one end with a hose clamp. Dip 1/2" of water, place it out of the way in the canoe bottom and set the transducer in the cup. Easy, clean, effective and removable.
