With a 120° field of view and a fast update rate of 30Hz, the Gemini 720is is ideal for poor visibility environments.

The Gemini 720is is supplied with Seanet Pro, Tritech’s data acquisition and logging software, which offers users the ability to network and operate the sonar along with a range of other Tritech sensors from a single software interface.

The Gemini standalone software also provides users with additional control over the Gemini 720is and can be upgraded to Gemini SeaTec to provide a variety of target classification and tracking capabilities. The capability to record

data in a range of digital video formats and output screen shots for review comes as standard.
