I got a spare if you want it Derrick. It'll cost 5 bucks or 2 beers. Your choice.

part # 72023015 (for the 1.5") and 72023016 (for the 1")
I've seen mounts made out of PVC but this is the wedge mount from hobie.

Awesome sin coast! How about i see your 2 beers an raise it a shot of crown

Im ordering the lowrance elite 4 kit for it now so i can just clip it on

I use the same thing as pictured above.

Ordered the lowrance elite 4 gps yesterday lol...supposed to be here next Thursday. And it better be! Or else I'll still be using the crappy old Lowrance @ forebay.

I love my elite except of at gs6 where it didnt turn off when i hit it an it drained my battery an fished blind lol

I original did the same; but then thought about "what if I wanted to use a sail", so I ended up mounting the fishfinder on the kayak rail using a Scotty flush mount and the Scotty Fishfinder bracket. it brings the fishfinder a little bit closer to me; making it easier to see and reach. Plus I use the Ram ball now for my "vanity" camera (gopro)...

The kit for the elite comes with a 1" ball mount for the yak if i wanna move it closer to in sure ill use em both just depending how much im messin with it
