I have multiple kayaks. Each kayak has it’s application. When I was selecting a fish finder, my primary requirement was mobility. I needed a solution that that I could quickly move between kayaks: battery, unit, and transducer. The most challenging part was the transducer. I chose the Ram Mounts Transducer Arm.

The Ram Mounts Transducer Arm comes with a straight aluminum rod. You need to put a 90 degree bend at the right point on this rod. Bending a 90 degree angle into the straight aluminum rod is easy, if you have a jig! Download and print my jig template. Cut out the template and trace it onto a scrap piece of wood (e.g. 1.5″ W x 3.5″ H x 3″ L). Cut along the lines via band saw or jig saw. (Wear eye protection!). Drill a 0.5″ hole via power drill through the center of the jig.

Secure the Ram Mounts 1″ ball and clamp to your kayak’s gear track. Insert the aluminum rod into the clamp. Pass the jig through the aluminum rod. With a Sharpie, mark the aluminum rod at the end of the jig. Remove the aluminum rod and jig from the clamp.

Secure the jig to a work bench via clamp. Adjust the aluminum rod until the Sharpie mark is aligned with the edge of the jig. Gradually bend the aluminum rod.

Mount a stock piece of wood on the other side of the rod. Gradually bend the rod in the opposite direction to form a 90 degree angle.

Attach the bent aluminum arm to the Ram Mounts clamp on your kayak’s gear track. Insert the plastic sleeve onto the aluminum arm. Secure the transducer housing to the end of the aluminum arm.

The RAM Mounts Transducer Arm provides me with maximum mobility. When I need maximum speed on the water, I rotate the arm until it’s parallel to the water. Great product! Perhaps some day it will come with it’s own jig to bend the aluminum rod.
