MicronGemini multibeam sonar - Tritech

The MicronGemini is the latest addition to the Tritech’s Micron and Gemini product families. It is incredibly compact and light-weight, offering a cost-effective solution for obstacle avoidance and navigation of small ROVs/AUVs. 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.
