This Product Spotlight focuses on DeepWater Buoyancy’s shallow water Instrument Bottom Mounts.

Instrument Bottom Mounts
DeepWater Buoyancy’s BTM-AL50 bottom mounts are designed for ADCP deployment in shallow ocean waters, rivers, coastal areas, and anywhere else where the size and remote recoverability of the AL-200 and AL-500 TRBM are not required.
These rugged diver-serviceable tripods come ready to accept your ADCP and battery canister, and can be modified to fit CTD, wave / tide gauge, velocimeter or other instrumentation.
BTM-AL50’s are manufactured using 5000 series aluminum, galvanically-isolated fasteners, and are fitted with zinc anodes for superior corrosion resistance. The double axis gimbal keeps your ADCP oriented to vertical after deployment and is manufactured using ultra-high molecular weight polyethylene to deter marine growth.
The units' three foot pads are supplied with through holes for ballast or for spiking, depending on your application. Standard (10lb/4.5kg) urethane-coated ballasts are provided for each of the three legs. Additional ballast is available upon request.

BTM-AL50-A
This traditional welded unit can be deployed by diver or lowered to the seafloor by line from small vessels. Instrumentation is easily accessible for battery change out or maintenance.

BTM-AL50-B
Like the traditional unit in all other ways, this robust bottom mount is collapsible for ease of transportation and lower shipping costs. The pinned and bolted design makes for a quick and easy assembly. A brace kit is also available for additional stability with increased payloads.
