About Oculus M-Series

Oculus M-Series sonar heads provide a 130-degree horizontal aperture and model-specific frequencies from 375 kilohertz to three megahertz. Operators can trade long-range detection against finer image resolution, with catalogue ranges extending to 200 metres and image updates reaching 40 hertz.

The compact aluminium units are rated to 500 metres and connect through Ethernet, while titanium MT and MD variants extend operation to 1,000 and 4,000 metres. Integrated pressure and temperature sensing supports sound-speed correction. The family mounts on inspection ROVs, work-class vehicles, AUVs and diver systems for navigation, structure inspection and target identification.

Timeline

  • Blueye integrates Blueprint Subsea Oculus multibeam sonar with X3 ROV

    2025-01-09 - Capability - Blueye published a January 9, 2025 integration article for Oculus multibeam sonar on the Blueye X3 ROV. The article describes Blueprint Subsea Oculus sonar as a high-end sensor integrated mechanically and in the Blueye App. The integration gives Blueprint Subsea a concrete ROV platform reference for low-visibility navigation and underwater inspection.
