Tritech International Limited is a high-technology business dedicated to providing the most reliable imaging and ancillary equipment for use in underwater applications. Tritech operates in many professional underwater markets, including; Defence, Energy, Engineering, Survey, and Underwater Vehicles.


Product Summary

Tritech remains an industry leader in the provision of sensors and tools for ROV and AUV markets, a reputation achieved from over 25 years of delivering expertise through key products such as the Super SeaKing mechanically scanning sonar (shown above), the industry-standard for obstacle avoidance and the renowned Gemini 720i sonar, for real-time multibeam imaging with a fast update rate.


The StarFish range has gained worldwide recognition as the most compact and affordable towed side scan sonars for the professional underwater survey industry.

The unique shape of the StarFish systems dramatically improves the stability of the sonar, as well as the quality of the images it produces. Using advanced digital CHIRP (Compressed High Intensity Radar Pulse) acoustic techniques, the StarFish systems offer better range resolution compared to conventional, fixed-frequency side scan sonars.
