Instrument Bottom Mounts
Diver-serviceable aluminum BTM-AL50 tripods for deploying ADCPs and other instruments in shallow ocean waters, rivers and coastal areas.
Description
The BTM-AL50 bottom mounts are designed for ADCP deployment in shallow ocean waters, rivers and coastal areas where the larger trawl-resistant mounts are not required. The diver-serviceable tripods accept an ADCP and battery canister and can be modified for CTD, wave/tide gauge, velocimeter or other instruments.

- 5000 series aluminum with galvanically isolated fasteners and zinc anodes
- Double-axis UHMW polyethylene gimbal keeps the ADCP vertical
