The underwater vehicle industry (UVI) has grown steadily since the 1980s, when Mesotech introduced their original 971 Scanning Sonar which quickly became an industry staple. For a variety of reasons, the use of remotely operated vehicles (ROV's) and autonomous underwater vehicles (AUV's) is preferred for many subsea applications. Kongsberg Mesotech continues to supply the industry with superior products including scanning sonar, multibeam sonar and altimeters.

Imaging and profiling sonar are both used on underwater vehicles. Imaging sonar is used for visual interpretation and uses a fan-shaped acoustic beam to scan a specified area or target. Profiling sonar is primarily used for quantitative measurements where a narrow, conically shaped beam generates a single point for each ping.

Single-beam scanning sonar

  • Two versions of single-beam sonar heads: high-resolution and domed
  • Range of products available with depth ratings from 650 to 11,000 metres
  • Variety of frequencies and feature configurations available
  • Reliable and low maintenance systems
  • Requires MS1000 software to operate sonar and process data

M3 multibeam sonar

  • Combines the high refresh rate of a conventional multibeam sonar with image quality comparable to a single-beam sonar
  • True zoom windows that enable target evaluation while continuing to operate ROV
  • Close range viewing capability and long-range obstacle avoidance capability
  • Real-time imaging
  • Two versions: 500m depth rating and 4000m depth rating
  • Requires M3 software to operate equipment and process data

To M3 Multibeam Sonar information



  • Primarily used on underwater vehicles to determine height above the seabed
  • Designed for deep ocean applications with some models rated to 11,000 meters
  • Range of models and frequencies available to suit different specifications
  • Designed to operate in stand-alone mode or connected to the MS1000 processing software
