Description

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 previously.

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.
