Tritech Gemini 1200ik Multibeam Imaging Sonar

Tritech Gemini 1200ik Multibeam Imaging Sonar operates at two acoustic frequencies, 720 kHz for long range target detection, and 1200 kHz for enhanced high-resolution imaging

The Tritech Gemini 1200ik multibeam imaging sonar is a powerful addition to the popular Gemini range. The multibeam imaging sonar offers two operational frequencies with the ability to switch between low and high frequency dependent on the user’s requirement. 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. Switching frequencies can be set to automatically switch over at a specific range or done manually.

Gemini 1200ik | High resolution, dual-frequency imaging multibeam

The Tritech Gemini 1200ik multibeam sonar operates at two acoustic frequencies, 720kHz for long range target detection, and 1200KHz for enhanced high resolution imaging at shorter ranges. Switching between acoustic frequencies is done either manually or automatically at a range set by the user.

- Software development kit available

Unique to the 1200ik is the ability to maintain a 120° field of view when operating at high frequency. This allows the target of interest to remain within view at all times, even when the target is in the nearfield. CHIRP processing ensures that the Gemini 1200ik can provide high-resolution imaging at longer ranges,while the integrated VOS sensor ensures the image is displayed at a high degree of accuracy.Operating  to a depth of 350m, the Gemini 1200ik can be used on a range of small to mid-size vehicles, as well as installed on larger vehicles operating in shallow water.

The Gemini 1200ik is fully compatible with Tritech’s software package, Genesis, which improves userinteraction and allows control of a number of Tritech sensors from within one software package. With the same physical size and identical interface connection, the Gemini 1200ik can be swapped out with any 720ik which is already installed, providing an easy upgrade path to higher resolution imaging.
