Description

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. Its 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 Helmet 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 data acquisition and logging software – Seanet Pro – which offers users the capability to operate multiple Tritech sensors using a single software program.
