The M3 Sonar® HF is a high-frequency multibeam sonar with both imaging and

profiling modes. It’s image resolution is double that of the original M3 Sonar.

When your mission depends on identifying small features and

targets with absolute confidence, high-frequency sonar makes all

the difference. Operating at frequencies ranging from 700 kHz for

extended range up to 1400 kHz for ultra-high resolution close-up

work, the M3 Sonar HF delivers centimeter-level feature detection

that reveals details invisible to traditional bathymetric surveys.

High-frequency operation means sharper images, clearer

target definition, and the ability to distinguish features that lower

frequencies simply miss. Whether you’re conducting infrastructure

inspections, search and recovery operations, archaeological surveys,

or detailed seafloor mapping, the superior resolution of high

frequency sonar transforms how you see the underwater world.
