Tritech’s Gemini multibeam imaging sonar provides users with real-time, crisp imagery for applications including obstacle avoidance, target detection and close-range inspection.

Now with the latest electronics Tritech presents the next generation Gemini 720is imaging sonar.

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 720 kHz 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).

GEMINI 720ik


The Gemini 720ik is the latest generation from Tritech’s renowned multibeam sonar range and is ideal for small ROVs and shallow water operations.

At 1m range, this product offers a world-class 97Hz update rate for video-like imagery. Target tracking algorithms developed by SeeByte are embedded within the Gemini software as standard.

A real-time, high frequency imaging solution, the Gemini 720ik operates at 720kHz and combined with Tritech’s advanced processing electronics, it produces images of outstanding clarity, benefiting from 512 beams which results in a 0.25° effective angular resolution.

The Gemini 720ik has been developed specifically for shallow water operations with low power consumption and Compressed High Intensity Radar Pulse (CHIRP) processing for greater definition at long range. The product also has an integrated Velocity of Sound (VoS) sensor to ensure extremely accurate imaging and measurement. The Gemini 720ik is supplied with Seanet Pro, Tritech’s data acquisition and logging software, which offers users the ability to operate a number of Tritech sensors using this single software program.

A stand-alone Gemini software package provides users with a range of additional software features. This software can be upgraded to Gemini SeaTec for target identification, classification and tracking. The capability to record data in a range of digital video formats and output screen shots for review comes as standard.
