Fishfinder Setup for Kayak Fishing

It's winter and it's cold, one dream of summer and sea.
Thought it a good time to get my fishfinder setup ready for December's kayak fishing.
Had the fishfinder last December already but struggeled to keep everything together (battery, wires, sensor and display)

Started with a piece of Marineply wood.
Cut some holes for a ratched strap that will secure everything to the kayak again in the end.

Then secured the frame of the Display to the wood with screws.

The battery you want to keep as dry as possible, so I took a watertight plastic container to use as housing.The holes that were drilled for the cable and screws was just big enough for a tight fit.

Then secured the plastic container to it's place on the wood with 2 srews.

Houston we have power !

Now to add the sensor. Would like to keep everything together. Hmmmmm . . . . . .
Came up with this:

Folded in and out:

Everything in a convenient carry option:
