M3 Sonar HF

Multibeam sonar

Skip to content

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.

High-resolution

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.
