Will be using this in the kayak. Will let you know how it does. Looks like a very easy install. No tubes and such.
Scan right thru the hull of the kayak.

Gander Mountain had them on sale for $179. Originally like $299. YOu can find them on the internet for like $229.
I think our store still has like 3 of them.

Pretty sure it is being phased out(aren't they all).

Plus it has a hard mount for boats. Just what the Doctor ordered!
