Take your seabed surveys into an exciting new era. KATFISH provides Ultra High Definition imagery and 3D bathymetry to enable real-time seabed mapping at extremely long ranges.

KATFISH acquires over 3 billion pixels per 3km2 per hour of area coverage rate. That’s 30 times more detail than conventional side scan sonar. Advanced algorithms perform thousands of adjustments per second to ensure every pixel displays data with incredible clarity.

KATFISH is engineered using our innovative and proven Synthetic Aperture Sonar technology - now deployed in over 10 countries by leading military and commercial operators.

KATFISH provides the industry’s highest resolution seabed pixels at the lowest cost.
