GeoAcoustics launches new low-voltage boomer at Oceanology International 2026

PRESS RELEASE

9th March 2026 – For Immediate Release

ExCeL London, UK: Sonar manufacturer GeoAcoustics Ltd has expanded its sub-bottom profiler portfolio with the launch of GeoPulse LF 101, a new low-voltage boomer system. GeoPulse LF 101 makes its industry debut this week at Oceanology International 2026 at ExCeL London (stand P400), introducing one of the lowest-voltage boomer sub-bottom profilers currently available to the marine geophysical sector.

Designed as a safe and practical solution for marine seismic survey, GeoPulse LF 101 operates up to a maximum of 1000 V DC, substantially lower than traditional boomer systems that can run at up to 4000 V. This lower voltage architecture supports improved handling safety and simplifies vessel integration, particularly on smaller platforms. A compact, portable energy source and lightweight cable reduce mobilisation demands, enabling efficient deployment for diverse applications including subsea construction, in addition to wind farm, cable route and infrastructure surveys.

The launch expands GeoAcoustics’ existing sub-bottom profiler range, complementing the GeoPulse 2 and GeoPulse Compact systems by introducing lower-frequency capability for deeper penetration in more challenging ground conditions. Together, the portfolio provides surveyors with a coherent toolkit spanning high-resolution shallow work through to deeper geophysical investigation. The company also draws on extensive experience in deep-water systems as the OEM for Kongsberg Maritime’s TOPAS sub-bottom profilers, bringing proven signal integrity and engineering discipline into this new boomer platform.

Richard Dowdeswell, CCO at GeoAcoustics, says: “GeoPulse LF 101 reflects a very deliberate approach to product development. We have taken established boomer principles and re-engineered them around safety, practicality and data quality. By lowering the operating voltage and simplifying deployment, we are giving survey teams a system that is easier to mobilise and safer to operate, without compromising performance. It is a natural addition to our sub-bottom range and an important step in broadening our geophysical capability.”

Visitors to stand P400 can see GeoPulse LF 101 alongside the company’s full hydroacoustic technology portfolio, including a new multibeam echosounder and side scan sonars, as the company continues to expand its offering for marine, offshore energy and geotechnical applications.
