The GeoScan 2491 is a simultaneous dual-band,
high-definition Side Scan Sonar designed for a
diverse range of survey applications. Operating at
400 kHz and 900 kHz with a 60 kHz bandwidth,
the GeoScan 2491 is designed for end-users that
need the best image resolution.

The GeoScan 2491 uses ultra-short pulses and
pulse compression technology for improved range
resolution across track and image resolution. A
dynamic variable aperture focusing system
improves resolution at shorter ranges and quality at
longer ranges, and an automated image equalisation
system enhances contrast and definition.

The GeoScan 2491 contains an embedded pitch,
roll & heading sensor, and a pressure sensor for
depth measurement. Ideal for underwater
infrastructure inspections, pipeline surveys,
emergency response, archaeology, marine pasture
assessments, and environmental monitoring, it
delivers precise, high-resolution data in demanding
conditions.
