combined sidescan


The Seaprobe DT Combined Sidescan & Sub-Bottom System is a field-proven deep tow system which collects sidescan sonar and sub-bottom profiler data for a wide range of applications in water depths up to 2500m.

The SeaProbe DT is a fully integrated combined sidescan and sub-bottom system and is fitted with a 100/340kHz dual simultaneous frequency sidescan which provides a combination of high resolution and extended range performance. A high power sub-bottom profiler with adjustable frequency output offers increased penetration with impressive resolution imagery.

The SeaProbe DT Towfish is a digital and extremely robust platform designed for hydrodynamic stability for improved tow performance in challenging conditions. The Multilink System provides a high bandwidth digital telemetry link over a single coaxial cable of up to 6000m in length for two-way communication between the topside and the SeaProbe DT. The system also supports a transparent communications link for additional sensors such as magnetometer, gradiometer, USBL responder, sound velocity and INS to provide a versatile survey tool.

The Multilink Sonar Processor is a powerful workstation running the new MonitorPlus data acquisition and replay software. The software provides enhanced display of the sidescan and sub-bottom data, along with an extensive range of online QC features, including a choice of recording formats to support direct compatibility to industry standard post-processing software suites.
