The Tritech Gemini 720i sonar provides real-time, crisp imagery of the underwater scene ahead, making Gemini the ideal technology for subsea sonar vision for obstacle avoidance or search & rescue (SAR) operations.

The sonar head weighs just over 1 kg in water and is designed to be easily integrated onto the VideoRay Pro 4 ROV platform.  It features a 720kHz operating frequency, a 120º field of view (FOV), and state of the art processing electronics, including an integrated sound velocity sensor which assists in providing the sharpest image possible with accurate ranging.  The Gemini 720i is also supplied with Gemini's standalone software that works alongside the VideoRay Pro 4 Cockpit software.

Typical VideoRay ROV / Gemini sonar applications are:

 

  • ROV navigation
  • Search & Rescue (SAR)
  • Obstacle avoidance
  • Target recognition
  • Salvage operations
  • Subsea monitoring & inspection

An Integration Skid is required to operate the Gemini Imaging Sonar from the VideoRay Pro 4 ROV platform.  This skid, which provides buoyancy and holds the sonar head and communication electronics, mounts to the ROV in seconds so it can be added quickly when needed or taken off when visibility is good.  All Pro 4 configurations including an imaging sonar are delivered with an Integration Package containing the skid mount and all necessary cables and software.

The Tritech Gemini sonar is not optimized for use on Pro 3 E, S, XE, GTO or lower VideoRay ROV.

Open Enrollment Certified VideoRay Training is available for the Tritech Gemini sonar and is included with any VideoRay Pro 4 ROV configuration containing a Gemini sonar system.
