M3 Sonar HF

Multibeam sonar

The M3 Sonar HF is a high-frequency sonar with imaging and profiling modes. It is an impressive upgrade to the original M3 Sonar, with an all-titanium construction and two-hundred percent higher resolution.

Distortion-free images over a 140° sector

Delivering superior image quality and coverage, the M3 Sonar HF provides high-quality distortion-free images over a 140° sector, reducing the time it takes to search for and locate targets. This versatile multibeam sonar offers both imaging and profiling capabilities.


Imaging data gathered from the M3 Sonar HF is high resolution, with cm-level feature detection capabilities that can be exported to a GeoTiff image. Features can be detected in imagery data that are not apparent in traditional bathymetric data. In addition, using the M3 Sonar HF with a third-party software driver, such as SoundTiles software, provides automatically-mosaiced images.

Bathymetric data

The M3 Sonar HF also provides excellent bathymetric data at very low cost. For profiling, using this sonar with HYPACK Hysweep provides 3D point-cloud data.
