excellent info! i got the monitor mounted on a piece of plastic  with velcro so its easily moveable to either seat of the canoe or other canoes. all you need it a 4" x 2" strip of the hooks side of velcro and you are ready to go. i plan to make a streamlined piece for the transducer mount as well, although that isnt going as smoothly as i had hoped. im struggling to design the bracket to be thick enough to securely hold the screws, but also thin and streamlined enough to eliminate most of the drag. the suction cup unit has quite a large plastic piece used to secure the cup so im leaning away from that plan.
