Great Yarmouth, UK: GeoAcoustics Ltd will debut a new Side Scan Sonar range at Ocean Business 2025 next week, marking a major addition to its extensive hydroacoustic technology portfolio.
Designed to deliver superior visualisation for diverse marine survey applications, the GeoScan range currently features two models, both offering simultaneous broadband dual frequency operation and advanced sonar processing features.
The GeoScan 2361 operates at 300 kHz and 600 kHz to maximise range performance, while the GeoScan 2491 runs at 400 kHz and 900 kHz to deliver even higher image resolution. Both include a fast 60 kHz update rate, CW and Chirp pulse options, no near-field blurring, and a maximum operating depth of 300 metres.
“GeoScan is a significant addition to our product offering,” said Richard Dowdeswell, Chief Commercial Officer at GeoAcoustics. “It reflects our commitment to continuous innovation and builds on the long success of our Side Scan Sonar system to deliver even more detail, clarity, and flexibility in real-world conditions.”
GeoScan features high-definition capabilities that combines ultra-short pulses and pulse compression to enhance image resolution and range definition. A dynamic variable aperture focusing system enables higher resolution at shorter ranges and improved image quality at longer ranges, while an automated image equalisation function ensures high contrast across different seafloor types.
Both models include integrated pitch, roll, heading and pressure sensors for precise navigation and depth measurement, helping users to collect accurate, high-resolution data in the most demanding underwater environments.
Typical applications for the GeoScan family include Search and Recovery (SAR), hydrographic surveying, object detection and identification, inspection and engineering support, and marine geology and archaeology.
With more than four decades developing industry-standard bathymetric sonar, sub-bottom profiler and side scan sonar systems, GeoAcoustics continues to support a global user base through a trusted network of over 50 partners covering more than 70 countries.
Visitor to Ocean Business can see the GeoScan system alongside GeoAcoustics’ latest bathymetric sonar and sub-bottom profiler technology at Ocean Business 2025, on Stand H4.
