Good advice KF.  Thanks.  With the silicone mount it is relatively easy to change the location of the transducer as it peels off with little effort.  I think I'll move it under the bow seat.  I should mention that my canoe doesn't have a gel coat on the inside so to make the surface smoother I first laid down a thin coat of epoxy.  Here's a decent video for installation.    (You need to Login or Register
