Tritech releases dual frequency Gemini sonar

9 September 2019

Tritech International has released the Gemini 1200ik dual frequency multibeam imaging sonar, the latest addition to its Gemini range.

The 350m depth-rated Gemini 1200ik offers the ability to switch between low and high frequency depending on user requirements. The 720kHz low frequency setting is designed for target identification and obstacle avoidance at long range, whilst the 1200kHz high frequency setting offers extremely detailed multibeam images, ideal for inspection at close range.

Frequency switching can either be set to happen automatically at a specific range or manually triggered. The system has the unique ability to maintain a 120° field of view across both frequencies, ensuring the target remains in view when operating at high frequency and at short range.

Significant engineering development enables this sonar to offer a 2.4mm range resolution, as well as an effective angular resolution of only 0.12°.
