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.
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.
