So does anyone have experience with this particular transducer mount? I think these guys are in Canada, eh?

No experience, but it looks like it could work.

It looks pretty interesting. Less bulky and possibly easier to use than the ram mount. I suspect you could tape the magnet inside the hull so you don't always have to reach in to mount it. Would love to hear if anyone has tried it. I am tempted to go ahead and order it.

Edit: I was about ready to submit my order but there is a $16 S&H charge on top of the $86 for the mount itself. The S&H charge seemed excessive so I cancelled. Might change my mind later but $102 total is pretty high for a few magnets and connectors.

I completely agree! I cancelled my order when I saw that 20% shipping premium. All I could figure is that it is Canada, but still ...

shouldn't be to hard to replicate with some really good magnets and a trip to the hardware store.

Talked to them about shipping and that "is their cost" coming from Canada. Now I am shifting over to the RAM idea (since I am already deep into that system). http://www.rammount.com/products/kayak/transducer --- now trying to figure out which mount for a Humminbird Helix 5 transducer with sidescan? Stepping off into rocket science ... and possibly a death spiral.

Thanks for the info. It probably would have felt better if the product was priced slightly higher with a lower shipping charge, but $16 shipping was a shocker. I already have the ram mount so spending over $100 to get something else seems foolish but being a fool has not often gotten in my way in the past. I may spring for it eventually because it seems less bulky on the side of the kayak and when I take it off the kayak, the ram mount and transducer is clumsier to transport and store.

Will post a review if I do spring for it.
