HARDWARE VARIATIONS AND COMPATIBILITY
The 6205s2 Bathymetry & Side Scan System contains both standard and proprietary hardware. At times,
EdgeTech may change the standard components due to their availability or performance improvements.
Although the component manufacturers and their models and styles may change from unit to unit,
replacement parts will generally be interchangeable.
EdgeTech will make every effort to see that replacement components are interchangeable and use the
same software drivers (if applicable). At times, however, direct replacements may not exist. EdgeTech will
provide the necessary drivers with the replacement part when this happens.
EdgeTech may also change certain hardware per customer requirements. Therefore, portions of this
manual, such as parts lists and test features, are subject to change. These sections should be used for
reference only. When changes are made that affect system operation, they will be explicitly noted. Also,
some options and features may not be active in the customer's unit at the time of delivery. Upgrades will
be made available when these features are implemented.

RETURNED MATERIAL AUTHORIZATION
Prior to returning any equipment to EdgeTech, a Returned Material Authorization (RMA) Number must
be obtained from CUSTOMER SERVICE.
RMA Purpose
The RMA Number identifies returned equipment when it arrives at our receiving dock and enables tracking
while at our facility. Refer to the RMA number on all documentation and correspondences.

Although rugged, these cases are not intended to be used as shipping
containers, and the delicate internal components could be damaged.
Shipping in this manner will void any warranties.
NOTE: All shipping charges shall be the customer's responsibility, unless
under warranty, as EdgeTech will pay for return shipping.

1.0 OVERVIEW
The EdgeTech 6205s2 is a fully integrated swath bathymetry and dual-frequency side-scan sonar system
that uses multiple receive elements and one discrete transmit element to produce real-time high
resolution, side-scan imagery, and three-dimensional maps of the seafloor. The 6205s2 overcomes the
limitations of multibeam echo sounders (MBES) and interferometric systems in shallow water using
EdgeTech’s unique Multi-Phase Echo Sounder (MPES) Technology. This hybrid approach combines
beamforming and phase discrimination techniques to determine each sounding along the seafloor. With
the integration of EdgeTech’s Full Spectrum® CHIRP technology, the 6205s2 exceeds IHO SP-44, NOAA,
and USACE specifications for feature detection and bathymetric point data uncertainty.
EdgeTech’s MPES technology enables the 6205s2 to produce a wider and cleaner swath (over 200°) than
current technologies, resulting in superior coverage enabling faster and safer survey completion. In
addition, the 6205s2 concurrently rejects multipath effects, reverberation, and acoustic noise commonly
encountered in shallow water environments.
The 6205s2 provides simultaneous dual-frequency side scan sonar, operating at 520/850kHz,
850/1600kHz, or 520/1600 kHz. The bathymetry operates at either 520kHz or 850kHz.
Additionally, EdgeTech’s latest 2205 Electronics and Modular Arrays are utilized in the 6205s2, resulting
in an extremely lightweight design required for shallow water applications and vessels of opportunity. The
2205 electronics and arrays are mounted onto a streamlined body deployed over the bow or side or
underneath a crewed or uncrewed survey vessel. Sonar data is transferred from the transceiver to the
processing unit onboard via an Ethernet network interface.
The 6205s2 system and its available integrations offer a powerful and versatile acquisition system suitable
for many different survey applications. It includes an integrated sound velocity sensor. It interfaces with
most third-party acquisition and processing software packages, standard DGPS/RTK GNSS systems,
heading, motion, sound velocity profilers, and INS.
The 6205s2 key features include:
•Next-generation MPES technology
•Unrivaled swath coverage in shallow water, when compared to other single head systems
•Swath sectors of up to 200°
•Co-registered dual-frequency side scan and single-frequency bathymetry
•Superior multipath rejection
•IHO SP-44 Special Order compliant
•Equidistant and equiangular soundings output options
•Comes with EdgeTech’s Discover Bathymetric Sonar Control Software
•Motion tolerant side scan
•Optional integrated OEM RTK GNSS aided INS unit
•Optional EdgeTech 3400-OTS-based sub-bottom profiler kit that integrates sub-bottom data with
6205s2 bathymetry and side scan data.

1.1 Applications
The 6205s2 next-generation Swath Bathymetry & Side Scan Sonar has many potential applications, a few
of which include:
•Shallow Water Hydrographic Surveys
•Benthic Habitat Mapping
•Nautical Charting
•Military Rapid Environmental Assessments (REA)
•Route Surveys
•Dredging Operations
•Marine Debris Search
•Port & Harbor Security
1.2 6205s2 Configuration Options
There are four configuration option choices to be made:
•Which frequency pair is required?
•Would you like a rack-mounted topside or a custom integrated stack interface unit?
•Whether or not to have the OEM integrated RTK GNSS aided INS unit?
•Would you like to have the 3400-OTS-based Sub-Bottom Profiler Kit?
1.2.1 Frequency Options
The 6205s2 is available in the following standard frequency configurations:
•520 / 850 kHz Dual Frequency Side Scan with 520 kHz Bathymetry Data
•520 / 850 kHz Dual Frequency Side Scan with 850 kHz Bathymetry Data
•520 / 1600 kHz Dual Frequency Side Scan with 520 kHz Bathymetry Data
•850 / 1600 kHz Dual Frequency Side Scan with 850 kHz Bathymetry Data
1.2.2 OEM RTK GNSS Aided INS Unit
The 6205s2 requires data from a third-party peripheral time/position/heading/motion sensor. This sensor
can be COTS (commercial off-the-shelf). The sensor can be integrated as separate components to the
6205s2, or it can be an OEM unit where the GNSS processor is integrated inside the rackmount topside,
and the IMU is integrated inside the sonar head unit.
NOTE: When the 6205s2 includes the OEM Integrated RTK GNSS aided
INS unit, there is no need to use the RS-232 or LAN ports to receive data
from peripheral GNSS/Heading/Motion sensors.
