I picked up a Humminbird Helix 9 MEGA this spring, and would like to use it ice fishing this winter. I'd like to use the mapping feature while driving the four-wheeler, and then bring it into a flip-over shack once I've found a spot I'd like to try for awhile. I've got limited space on the front rack of my four-wheeler, as the ice auger takes up a decent portion of it. Has anyone built a fairly compact shuttle for a Helix 9? I've got it setup in my boat right now using a RAM ball mount - thinking maybe I can get away with putting another one on the front four-wheeler rack and just use a portable power source like a DeWalt battery adaptor. When I find where I want to fish, I'll just take the Helix off the ball mount and tighten it down onto another ball on some sort of shuttle.
Does anyone else do something similar to this? Definitely open to suggestions.
