you can shoot a helix ice fishing transducer straight through the hull of a canoe, jump the sensitivity up a couple points and youre ready to rock.
This is what I do.
I make a little donut with some ductseal putty on the floor of the canoe, fill it with water and drop the ice ducer in it.
When I'm done the trip the duct seal comes out to be used another time.
