Hey Mike,


Thanks for the info on the sonar signal passing through aluminum. Interesting, that the search beam can function when "shot" at a layer of metal; I'd have thought the ultrasonic beam would reflect. Shows what I know.

This is great news for those many thousands of people who own aluminum canoes. I hope they read your post, above.

Maybe some others will weigh in with results they've had while using "shoot through" rigs on yet other kinds of boat hulls.

What would be wonderful is if the basic rig works on EVERY kind of boat hull. I just have doubts this will be the case, especially with the sandwich hulls. (I'd love to be wrong, though!)
