Kongsberg Mesotech M3 Sonar: Multibeam Sonar Head

Availability: Ex-Rental Sale, Rental, Sale

Unique Group offers Kongsberg Mesotech M3 Multibeam Sonar Head which is the latest in multibeam sonar technology. The head which contains both imaging and profiling transducers, has a rapid refresh rate and the ability to configure complex pulses, making it ideal for a variety of applications.


It is used to generate high-resolution images that are easy to interpret due to its combination of a conventional multibeam sonar with image quality comparable to a single beam sonar.

The Multibeam sonar works similarly to a standard bottom long-range sonar, but instead of creating a single image, it generates up to 10,000 individual images, which are then merged on the boat’s console to create a final high-quality image of the area.

High-performance sonar head with a 16.8 kHz bandwidth that is densely packed.

Cost-effective and time-saving.

A simple-to-use touch-screen control is also available.
