Tritech Gemini 720IM SONAR

World’s smallest multibeam sonar

The Gemini 720im fuses Tritech’s Gemini multibeam technology 
with Tritech’s Micron technology to create the world’s smallest 
multibeam imaging sonar.

Having a 90° horizontal field of view and 50m range, with an 
update rate up to 20Hz, the Gemini 720im brings real-time 
imaging to places where multibeam was never possible before.

With incredibly compact dimensions the Gemini 720im can 
be used in applications where size is critical. This makes the 
Gemini 720im ideally suited for micro ROV/AUVs in addition 
to applications where space is restricted or weight is critical, 
including diver helmet and pole mounted applications such as 
Search and Recovery (SAR) operations
