Tritech Gemini 720is
The Gemini 720is operates at 720kHz and this combined with Tritech’s state-of-the-art processing electronics, produces images of superb clarity in harsh and deep water applications.
Description
The 720is is a key product in Tritech’s renowned multibeam sonar range and offers a realtime, high frequency imaging solution. The Gemini 720is operates at 720kHz and this combined with Tritech’s state-of-the-art processing electronics, produces images of superb clarity in harsh and deep water applications.
Features
- 720kHz operating frequency
- CHIRP processing
- Wide 120° field of view
- Real-time updates for video like imagery
- Integrated velocimeter for accurate ranging
Benefits
- Near field focusing
- 4mm / 0.2in range resolution
- Clear wide angle field of view
- Suitable for low visibility environments
- Easier interpretation of sonar imagery
With 120° field of view and a fast update rate, the Gemini 720is is ideal for poor visibility environments. The Gemini 720is is supplied with Genesis, Tritech’s data acquisition and logging software, which offers users the ability to network and operate the sonar along with a range of other Tritech sensors from a single software interface.
The Genesis software offers additional features such as target tracking and already allows you to run a number of other Tritech sensors alongside your Gemini 720is such as MicronNav 200 USBL tracking system and Mechanical scanning sonars.
