The XL is USM's gargantuan mount, designed to be used on large vessels and barge ships. This model is recommended for systems with Z-Pole lengths up to 25', bearing loads up to 300lbs.
Just like the Compact, Hightower, and Megatower, the XL uses a vertical lead-screw mechanism called the Shear Block Tower to engage and disengage the Z-Pole, also serving as a breakaway safety feature in the event of a collision.
SHEAR BLOCK TOWER

- Safe and audible release of sonar apparatus during collision or snag with submerged hazard
- Vertical lead screw engagement helps make raising & lowering the sonar easy
