GEMINI 1200ik Dual frequency multibeam imaging sonar

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.

The Gemini 1200ik multibeam imaging sonar is the latest addition to the popular Gemini range. The multibeam imaging sonar offers two operational frequencies with the ability to switch between low and high frequency dependant on the user’s requirement. The 720 kHz low frequency setting is designed for target identification and obstacle avoidance at long range, whilst the 1200 kHz 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.

Unique to the Gemini1200ik is the ability to maintain a 120° field of view across both frequencies: something not previously seen in any of the Gemini Multibeam imaging sonars and ensuring the target remains in view when operating at high frequency and at short range. 

Significant engineering development has resulted in this latest Gemini imaging sonar offering an impressive 2.4mm range resolution as well as an effective angular resolution of only 0.12°.

Used in conjunction with the Diver Mounted Display it also provides divers with real-time imaging in low-visibility conditions via a high-resolution diver display.

Unique to the 1200ik is the ability to maintain a 120° field of view when operating at both frequencies. This allows the target of interest to remain within view at all times, even when the target is in the nearfield.
