At ROV HIRE Australia we utilise the Kongsberg M3 Sonar

The M3 Sonar is a 2D multibeam system with imaging and profiling capabilities. The M3 Sonar provides high-resolution and easy to interpret images by combining the rapid refresh rate of conventional multibeam sonar with image quality comparable to a single-beam sonar.

Detection of small objects out to 150 meters combined with a 120° to 140° field of view allows the operator to see the complete underwater picture in real-time. Vertical Accuracy compliance can be met over the full ±60° sector for Order 1 surveys and to at least ±55° for Special Order Special Order target detection (1m cube) is met to 20m and Order 1A target detection (2m cube) is maintained to 40m.
