High Resolution and Domed Sonar Heads, 1071 / 1171

KONGSBERG is recognized as a leader in single-beam scanned sonar, developing systems with the highest quality and highest resolution on the market. It is feature-packed, and continuously being developed to meet the stringent requirements of the ever-changing subsea industry.

We manufacture two types of single-beam sonar heads within the 1071 and 1171 Series, both high resolution and domed. Each type of head has a wide range of product options and configurations to suit different applications, including Marine Engineering and Site Inspection, Search and Recovery, Underwater Vehicle Instrumentation and Surveillance.

High Resolution Sonar Heads

  • Narrower horizontal beam pattern and smaller angular resolution
  • Exposed transducer
  • Increased power output
  • Superior image quality
  • Requires MS1000 processing software to operate equipment and process data

1171 Series High-Resolution Scanning Sonar Heads

  • Telemetry: RS 485/RS 232
  • Operating Depth: 650 m to 11,000 m

Domed Sonar Heads

  • Transducers are protected within an oil-filled, pressure compensating dome (low maintenance)
  • Compact and lightweight, designed for deep sea ocean applications
  • Commonly used on ROV / AUV applications
  • Requires MS1000 processing software to operate equipment and process data
