Iceman's portable Fish finder

[Iceman]

How does the entire unit mount onto the yak? Does it have a ram mount on the bottom of the battery case to keep it in place?

1" RAM Ball on the bottom is the best I have come up with. I swap it between Hobies using wedge mount in the sail mast fitting. For other kayaks just add the Yakattak track.

Here is my original, I have used this one for a couple years with different head units.
