Transducer Arm
thingiverse
(DISCLAIMER: Ignore the markup signs on the thumbnail image, this was a gift for my father. The two attached files DO NOT have this writing on them.) These two pieces join together (Via one 1/16 bolt) to create a transducer arm for your ice fishing sonar. It has about an 8-inch reach and is pretty strong. It has two counter-sink holes for a nut on both jointed parts.
