Quote: Doesn't anyone just stick the transducer to the outside of the hull with a suction cup? I think there are plenty of ways to mount them BUT since you mentioned them being cumbersome mounted outside canoe, I think you answered your own question. If you were going in and just base-camping NO portaging then whatever is the quickest/easiest is what I would go for. The last thing you need on that 33 day trip is something snagging on portage or something you have to mount/dismount on portages. I'd figure a way to mount it ONCE and forget it.

Well, just playing devils advocate, I don't think a transducer stuck on the outside of the hull would be particularly cumbersome. Also, it clearly wouldn't be staying there for the duration of the trip, it would be stuck on when I'm ready to seriously fish then removed when portaging or simply traveling and not fishing. It's not that difficult to stick a suction cup on the side of the hull and remove it.  :)

But everyone seems to be a big fan of mounting it semi permanently inside the hull. I can see the advantages. I do really like your idea of using a small jar with a lid.  :)
