The Gemini 1200id is built on the same robust platform as the industry standard Gemini 720is sonar. It features a wide 120° horizontal field of view when operating at both 720 kHz and 1,200 kHz acoustic frequencies and offers improved attenuation of waterborne electrical noise for optimal imaging performance.

An integrated speed-of-sound sensor ensures that targets are displayed to a high degree of positional accuracy. CHIRP processing provides improved target separation over longer ranges.

The 1200id is fully compatible with Tritech’s software package, Genesis. This ensures improved user interaction and allows for control of multiple Tritech products from within one software package. Software development kits (SDKs) are also available for Windows and Linux operating systems.

Bruce Hardy, Sales and Marketing Director, commented: “We are really pleased to bring the new dual frequency Gemini 1200id to market. Having listened to our customers’ requests for higher definition and enhanced target resolution, we believe the new 12,00 kHz acoustic frequency will provide just that, along with Tritech’s reputation for quality and reliability, backed by our 3-year guarantee.”

Unrivaled Imaging Performance

The Gemini 1200id employs a completely in-house developed analog front-end solution that incorporates fully differential receiver channels for enhanced acoustic reception. Internal electronic circuits have been optimized and, where necessary, additional filtering exclusively employed to minimize self-generated noise. The sonar also actively attenuates external waterborne noise from other subsea equipment in the vicinity of the sonar. These enhancements enable the Gemini 1200id to produce sonar images displaying sharp and bright acoustic returns on a noise-reduced background, resulting in crisp sonar images of impressive clarity.

Asim Azad, Hardware Engineering Manager, commented: “With its ultra-low-noise differential analog front-end supporting a wide dynamic range optimized for sonar imaging applications, and with its ability to actively attenuate waterborne electrical noise from other subsea equipment, the Gemini 1200id provides work class ROV operators the clarity and confidence necessary for mission-critical operations.”
