OVERVIEW
The EdgeTech 2050-DSS (Deep Side Scan Sonar and Sub-Bottom Profiler) is a fully integrated tri-frequency
side scan and sub-bottom system that is particularly useful in conducting high-resolution sub-bottom
surveys close to the seabed. The system’s hydrodynamic towfish configuration options are currently a 2-
16 kHz sub-bottom profiler that utilizes a polyvinylidene fluoride (PVDF) panel receive hydrophone that
provides excellent sub-bottom receive sensitivity and directivity. The 2050-DSS system comes with either
a 120/410/850 kHz or a 230/540/850 kHz side scan sonar array using EdgeTech’s proven CHIRP technology
to provide crisp, high-resolution side scan imagery. The system is controlled, data is collected and
processed by a topside Starmux IV Digital link and an EdgeTech Discover Software enabled computer. The
2050-DSS can be integrated with auxiliary sensors such as a magnetometer, depth sensor, altitude sensor,
and a USBL responder. The system can also be integrated with an ROV (Remotely Operated Vehicle) with
a mounting kit.

Key Features
Fully Integrated Turn-Key System:
The system comes delivered to customer specifications with minimal
setup and configuration.
Tri-Frequency Side Scan Sonar:
The
standard 2050-DSS configurations
are either a 120/410/850 kHz or
230/540/850 kHz array that can
operate any two frequencies
simultaneously. The system
frequency choice can be
reconfigured instantly, allowing the
operator to react and optimize range
and resolutions to changing survey
conditions and to use the system in
multiple roles.
Sub-Bottom Profiler:
The 2050-DSS
system has enhanced sub-bottom
profiling capabilities with a low-
frequency transducer and a PVDF
receiver. Mounted within the system
is a single 2-16 kHz transducer that provides improved directionality and the ability to focus power where
needed. The PVDF receive panel provides 2D directionality and improved sensitivity over simple line
arrays.
Reflection Coefficient Calculation:
The Discover 2050 Software shipped with the 2050 system provides
reflection coefficient calculation to help with bottom sediment composition identification.
