Since 1978, GeoAcoustics has been manufacturing high end sonar equipment for side scan, bathymetry and sub-bottom profiling applications.
Side-Scan Sonar – Pulsar
Pulsar Side-Scan Sonar acquires high resolution acoustic images of the seabed. The pulsar is easily operated using the water protected deck unitand a small cable hand reel. A portable electric winch is also an available option. Some of the key features include:
- Portable and rugged towfish
- Easy deployment and intuitive operation
- Compact and water protected deck unit
- Frequency of 550 kHz – 1000 kHz
- Wide bandwidth FM and CW pulses
- Integrated GPS module
- Tow cable on hand reel and deck cable
- Dedicated acquisition and processing software
Geoswath4 Multibeam Echosounder
The GeoSwath 4 and GeoSwath 4R provides efficient and simultaneous swath bathymetry and side scan seabed mapping. The accuracy of the Geoswath 4 has been shown to exceed the IHO standards for hydrographic surveys. Some of the key features include:
- Ultra high resolution swath bathymetry
- Co-registered geo-referenced side scan
- Frequency versions: 125, 250, 500 kHz
- Up to 12 times water depth coverage
- 240 degree view angle
- Dual transducer set up with versatile mounting options
- Full software solution included
Sub Bottom Profiler – GeoPulse
The GeoPulse is the industry standard sub-bottom profiler system in the survey community. Additionally, the GeoPulse Pipeliner offers a solution to the problem of detecting buried pipelines. The GeoPulse has established itself as a market leader due to it’s reliability, ruggedness, ease of operation and flexibility. Some of the key features include:
- Selectable transmit frequency of 2-12 kHz
- Over the side, towed, or hull mounted deployment
- Reliable, proven, and easy to use
Sub Bottom Profiler – GeoPulse
The GeoPulse compact and GeoPulse Compact (Towed) is a high performance digital sub-bottom profiler. The user can choose waveforms in the frequency band of 2-18kHz, which allows the optimization of resolution and sub-seafloor penetration. Some of the key features include:
- Only 11% of the power requirements of previous systems
- Low noise
- Massive oversampling of the RAW signals (800kHz)
- Advanced FPGA based decimation and processing
- Over 100db of noise free dynamic range
GeoRGE Diagnostic Kit
The GeoRGE Diagnostic Kit was developed to simplify the process of fault finding. This kit helps determine whether a fault lies within the GeoSwath deck unit, the transducer cables, or the transducers themselves. The kit can be used with:
- GeoSwath plus deck unit
- GeoSwath plus compact
- GeoSwath plus ROV
- All transducer cables
