ROV SYSTEMS & PRODUCTSS ¯ Tritech’s New Gemini Sonar ¯ Tritech International

Subsea imaging technology provider Tritech International has launched a new dual frequency Gemini 1200id sonar, said to offer higher resolution imaging for work class remotely op- erated vehicles (ROVs).

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