With a 120-degree field of view (10 degree tilt) and a fast update rate of 30Hz, the Gemini 720is sonar is ideal for poor visibility environments. Gemini 720is features a 720kHz operating frequency and an integrated sound velocity sensor to assist in providing the sharpest image possible, with accurate ranging. Redesigned for ease of install onto a variety of ROVs, AUVs and other underwater platforms, the Gemini 720is operates through Ethernet or VDSL communications.
The sonar's compact size means that it can also be deployed using a pole-mount assembly (customer supplied). A standalone Genesis software package is available which offers users a tailored control and display interface including a click and track function and engineering measurement tools.
