Gemini 720ik

The Gemini 720ik is a real-time, high-frequency multibeam imaging sonar. Utilising Tritech’s advanced processing electronics, at 1m range the sonar offers a world-class 97Hz update rate to produce high-quality, video-like imagery. This compact multibeam imaging sonar has been specifically developed for shallow water operations; with low power consumption and Compressed High-Intensity Radar Pulse (CHIRP) processing for greater definition at long range.

The Gemini 720ik reduced size and weight, and proven reliable performance makes it the ideal sonar for use on ROVs for navigation, obstacle avoidance and target recognition as well as diver operations. Used in conjunction with the Diver Mounted Display it also provides divers with real-time imaging in low-visibility conditions via a high-resolution diver display.

The Gemini 720ik sonar is supplied with Tritech’s Genesis software which offers users the capability to operate multiple Tritech sensors using a single software program.


The Gemini 1200ik is a dual frequency version of the Gemini 720ik. The operating frequencies are 720kHz and 1200kHz for close inspection.
