Basic tube setup, with transducer shaft mounted to the left rear, behind the rod rack.
The transducer shaft is secured with a bungee cord, top and bottom, and rotates around the tube for protection when launching or beaching.
The transducer unit is screwed to a "T" connector on the bottom end of a 1/2" PVC shaft.
A piece of bungee cord is looped to fit over the "T" connector at the top of the transducer shaft.
The bungee cord is knotted around the shaft at the bottom, just above the transducer.
The transducer shaft is easily rotated down after launching, and rotated up before beaching, to prevent damage by rocks, etc.
The system easily converts to ice fishing, by adding a couple of lateral supports in the holes of the top T connector, to prevent the shaft from going down the ice hole.
A waterproof and insulated two compartment picnic bag works great to hold both the sonar system and assorted lure boxes, etc. The battery goes in the front, wrapped with a towel for extra insulation.
The two stabilizer pieces are not glued into the connector, so they can be easily taken down for transport in the bag.
When moving, or leaving, everything stows neatly in the picnic bag.
So far I have not had the new unit on the water, but have been favorably impressed by the reviews. With the "Fast Track" (real time) split screen graph system on the left, along with conventional fish marks, it seems to be an ideal combo unit for both tubing and ice fishing.
The price is right...only $149 at either Sportsmans or Cabelas. It has a lot of features for the money. Not a high end unit, but it puts out a lot of info at 1500 watts, so it will not suck your battery dry after a couple of hours.
