Who we are

Located in Great Yarmouth, UK, GeoAcoustics Ltd is a leading manufacturer of high-quality sonar equipment for bathymetry, side scan and sub-bottom profiling applications

GeoAcoustics was founded in 1978 as ORE Ltd. as a leasing operation of offshore research equipment, which included Side Scan, Profiling, SBL/LBL positioning and Acoustic Telemetry systems. 

In 1983 it was bought by Ferranti Industrial Electronics Ltd’s becoming part of the Offshore Industries Group and renamed Ferranti ORE Ltd.

 In 1991 it returned into private ownership and was renamed GeoAcoustics Ltd.  

In 2008 it was purchased by Kongsberg Maritime AS, operating in the Sensors and Robotics division and renamed Kongsberg GeoAcoustics Ltd

Following divestment from Kongsberg in December 2020, GeoAcoustics once again returned to independent ownership following a management buyout.

Side Scan Sonar

The Pulsar has been specifically designed for simple deployment and intuitive operation, capturing high resolution images of the seabed using a rugged tow fish which can be easily operated with a water-protected deck unit and a portable cable hand reel. The Pulsar operates within a 550KHz to 1MHz frequency with selectable FM and CW pulses, allowing the user to optimise the configuration to the survey task, making it ideal for applications such as search and recovery operations, object detection and identification, inspection of underwater structures, and marine archaeology.
