Product Portfolio

Bathymetric Sonar
Optimised for shallow water bathymetry and backscatter acquisition, GeoAcoustics’ interferometric systems provide a cost-effective alternative to traditional multibeam sonars. The flagship GeoSwath 4 delivers simultaneous depth and side scan data with AI-powered, real-time quality control and ultra-wide swath coverage. Its compact transducers and flexible mounting options suit both crewed and uncrewed surface vessels. Applications include hydrographic surveying, port and harbour mapping, environmental monitoring, and inland waterway surveys.

Side Scan Sonar
The compact GeoScan 2491 and GeoScan 2361 are durable towfish systems offering high-resolution dual-frequency imagery. Designed for both offshore and inland environments, they support marine infrastructure inspection, object detection, habitat mapping, search and recovery, and archaeological work.

Sub-Bottom Profiling
GeoPulse 2 leads the range of digital parametric sub-bottom profilers, providing high-resolution sediment characterisation and object detection in complex geology with minimal acoustic footprint. GeoPulse Compact offers a flexible alternative that balances penetration and resolution for geotechnical, archaeological, pipeline route, and dredging surveys. These systems are valued for clarity, durability, and repeatable results across a wide range of conditions.

Field-Proven Reliability
GeoAcoustics systems operate in varied environments, from Arctic fjords to equatorial deltas. They support hydrography, marine science, offshore energy, defence, and coastal engineering. All systems are designed for straightforward deployment, low power consumption, and compatibility with digital workflows and widely used survey software.

A Legacy of Innovation
Originally established as Offshore Research Equipment (ORE) Ltd, GeoAcoustics has evolved through key technological shifts, from analogue telemetry in the 1980s to AI-enabled, autonomous platform-ready solutions today. Since returning to independent ownership in 2020, the company has invested in product development, sustainability, and automation technologies to support the future of ocean and inland water surveying.
