The Z-Pole Stabilizer works with all USM Foil Z-Poles and is encouraged to be used when equipping your vessel with a Z-Pole of considerable length and/or a sonar head of considerable mass. It serves as a second tie-in point which significantly reduces Z-Pole flex while preserving the functionality of the Shear Tower, X-Pole Reach and Foil Clamp Yawadjustability. The Stabilizer Arm stows quickly and easily using a magnetic latch, allowing for inboard operation.
