Blueprint Subsea

The Oculus M1200d multibeam sonar from Blueprint Subsea is an excellent sensor helping the operator navigate, identify objects and increase situational awareness under the surface.
The sensor is especially useful when diving in murky waters, for search and rescue missions, or for jobs where you cannot rely on a camera solely to locate your target of interest.
The integration with the Blueye X3 ROV enables the operator to adjust the sonar vertically from -30° to 30° directly from the Blueye app.
Operating frequency: 1.2MHz / 2.1MHz
Range: 40m / 10m
Horizontal Aperture: 130° / 60°
Vertical Aperture: 20° / 12°
