i've heard they can shoot through the hull of a canoe? is it true? Purchased a new Humminbird and can't wait to use it in the BWCA!

I've used my vexilar through the bottom of my kevlar on a local lake just for depth and bottom composition. Worked just fine, found some brush piles too. You just have to find a way to keep a puddle of water under the transducer so the sound waves have a path to the water. I was going to try silly putty or something similar to make a little temporary pool for it to sit in. I rarely use a sounder in the canoe so I don't want anything permanent and the vex is too heavy for a suction cup.

Put a ring of silicone a little bigger than the transducer and fill with water. It'll shoot through and you can remove the silicone easily later.

There always seems to be a little pool of water between my Kevlar ribs. I just put the transducer in that spot and it shoots through and reads just fine.

T-I know you have a vexilar bwca locator. Question for you: does it matter what direct the transducer is facing? I've always just used the suction cup and mounted it on the outside of the hull in the stern, but I like the idea of keeping it on the floor and I think I recall reading somewhere on this site that the direction matters.

i have mine mounted on the bottom of my kayak. I used marine goop, but that is a more permanent way to put it on, if you plan on leaving it you can do this. Mine is a new lowrance unit, it works well for bottom compositionand depth as said before, but it is useless for water temperature for obvious reasons. It will finally read close to the actual temp after several hours of being in the water...

I have heard the same thing. I just have it sitting with the correct direction facing forward, but I know I have kicked it by accident and it was then facing sideways or backwards and I couldn't tell a difference in performance before I noticed it had moved.

Thanks, T. At least with it in the boat, it won't be flopping around in the water after the suction cup has come undone!

A kayaker in Austrailia posted one of the best methods for a non permanent wet mount transducer installation for shooting through kevlar work on kayakfishingdownunder.com:

Non permanent wet mount transducer installation

1) buy a cheap closed cell foam kiddie floatation vest device (< $10 swimoutlet.com)The vest contains 4 layers of foam ...enough to make 8 transducer mounts.
2) place the transducer on the foam, trace around it and cut the shape out with a sharp knife. You want a snug fit.
3)find a suitable mounting location. I think it best to mount under front seat and where there is no reinforcement ribbing to interrupt transducer signal
4)Apply a thin but solid bead of adhesive on underside of foam, completely circling the transducer hole cutout. Want to make sure the transducer cut out will hold water. I haven't installed mine yet but I think clear silicone would work. Any other ideas for a what type of adhesive would hold foam to kevlar? I would also place something heavy on top of foam cutout and silicon to get tight bond.
5)After 24 hour drying time ...place a large cup of water in transducer hole cutout and then push in your transducer. Accordingly, the water will displace all air between the hull and the transducer. You are ready to fish.

Many mount the transducer directly to the floor of their kevlar canoe and find it works well. Some find that their signal gets distorted because of air bubbles in the silicon adhesive. I feel it best to use the method described up above. It is not permanent and you should never have a distorted signal.

I have always used a suction cup transducer setup ... but when I was paddling across lakes it would slow me down and many times get in the way when I was landing big fish. I can't wait to try out my new wet mount thru the hull setup.

Good fishin'

This is exactly what I have done for my transducer reading through my cedar strip hull. I just used some foam from those insulating foam sheets you use on your basement or shop floor. That stuff has a million uses! It was very easy. Used silicone, so it would be no probs to remove it if I ever want to. I have a pic of it somewhere, I'll post it if I find it.
