The Oculus M series multibeam sonars are a new generation of compact imaging sonar, designed for use across a wide variety of underwater applications. Their small form factor makes them ideally suited for deployment onto micro-sized platforms, while their rugged construction also makes them an excellent choice for larger work-class vehicles and subsea infrastructure.
Model variations
M370s
With a 200m range capability, this sonar is a cost effective alternative to traditional mechanically scanned sonars, typically being used for long range navigation and situational awareness.
M750d
A general purpose dual-frequency 750kHz/1.2MHz sonar offering up to 120 metre range capability for navigation and high resolution imagery for near field target identification.
M1200d
Offering the highest resolution in the M series range, the dual frequency 1.2MHz/2MHz M1200d may be used for specialised inspection tasks where image quality is critical with ranges of up to 40 metres.
