I just got a little flat-back canoe yesterday and I have a Lowrance Mark5 ordered to go on it. Since it's a flat-back canoe I was planning on mounting the transducer on the transom. This one has what looks like a small flat area for mounting one fabricated into it. But I thought I'd ask some folks that have a lot more experience than I do (which is absolutely none).

I've included a picture of the transom (the flat part is on the upper left as you look at the pic). It looks like it would mount nicely there, I'm just wondering if I should maybe just mount it to the 30/30 TM I'm putting on it instead so that I don't have to worry about damaging the transducer when I'm loading/unloading the canoe on top of my car etc.
