The Vexilar Transducer Support Arm makes it easy to hang your transducer in position for more precise sonar. The Vexilar transducer arm fits any Vexilar pack with a rod holder and quickly attaches to your pack. Plus, the support arm floats, so you won't lose the arm underwater if it accidentally comes off. Ideal for serious ice anglers, the Vexilar Transducer Support Arm allows you to hang your ice transducer rather than use the float.
