USM MegaTower OTS Sonar Mount
Sonar Mount for 14 ft Z-Poles
Description
The Universal Sonar Mount (USM) MegaTower OTS Sonar Mount is a modular mount for repeatable, accurate alignment of a sonar head to a boat. It is made primarily from hard coat anodised marine-grade aluminium. The datasheet describes the MegaTower as a large-scale version of the HighTower, designed to withstand high working torque loads.
The USM MegaTower is recommended for systems with Z-Pole lengths up to 14 ft and bearing loads up to 200 lbs. A vertical lead-screw mechanism called the Shear Block Tower engages and disengages the Z-Pole and also serves as a breakaway safety feature in the event of a collision. Actuation lifts the sonar head to a position substantially parallel to the boat's deck, and the Z-Pole can be locked in the fore or aft position while the vessel is transiting.
On the USM MegaTower, yaw, pitch and X-Pole reach are adjusted inboard, Z-Pole depth can be indexed on the fly, and settings can be preserved and reproduced. USM offers Offset Lookup Tables to identify offset values for a specific configuration. Further listed features are calibrated Z-Pole breakaway, mechanically constrained and fully repeatable mounting options, complete electrical isolation of the sonar equipment, quick-release handles and portable flyaway travel cases.
