Model EM -Underwater Monitor - Diver Sled
A new hybrid system combines Aqua Survey-modified EM-61 high-powered Tx/Rx coils, Aqua Survey underwater monitors and Geonics’ EM-61 consoles with precision positioning/tracking equipment. Combining new with proven equipment brings the detection force of state-of-the-art high-powered Geonics equipment to the seafloor. It provides the diver real-time target response data, the ability to follow monitor-displayed survey lanes and the ability to view completed survey lanes.
Precision positioning the EM Diver Sled in the shallows is accomplished with a mast-mounted GPS antenna. In deeper waters a submersible USBL system is utilized to precisely position the receiver coil. Survey lanes can also be established from the placement of underwater control point monuments and the use of guide lines.
Aqua Survey has extensive experience utilizing EM-61-based EM Diver Sled technology on both sand and mud bottoms. Aqua Survey will provide diver-training in the use of the system.
