Tritech Micron Gemini 720s

Description

It is an obvious choice for the applications where size and weight are critical, but a small mechanical scanning sonar does not offer the required real-time imaging.

MicronGemini 720s is powered with Tritech’s robust hardware and state-of-the-art signal processing algorithms. The system operates at 720 kHz and offers an effective angular resolution of 0.7° and a range resolution of 8mm. In addition to its impressive compact dimensions, it has integrated sensors for depth and temperature and an optional AHRS for bearing, roll and pitch.

The MicronGemini 720s is also integrated into Tritech’s flagship Diver Mounted Display (DMD) system. The DMD enables divers to identify targets and navigate zero visibility water using a head-mounted sonar making the MicronGemini an excellent addition to this system given its small form factor and light weight.
