HARDWARE VARIATIONS AND COMPATIBILITY
The 2300/2300B Combined Sonar System contains standard and proprietary hardware. At times,
EdgeTech may change the standard components due to their availability or performance improvements.
Although the component manufacturers—along with 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. When this
happens, EdgeTech will provide the necessary drivers with the replacement part.
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.
Contact EDGETECH CUSTOMER SERVICE with any questions relating to compatibility.

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.
All returned materials must be shipped prepaid. Freight collect shipments will not be accepted. All
equipment should be adequately insured for shipping, but equipment belonging to EdgeTech must be
insured for full value.
If there is more than one item per consignment, include a packing with the shipment. An invoice can
double as a packing slip only when the contents are clearly numbered and identified on the invoice.
CAUTION! Never attempt to ship a portable topside in its rack mount case
alone. 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 2300 system combines EdgeTech's highly
successful line of side scan sonar and sub-
bottom profiler into one fully integrated
system. The 2300 tri-frequency side scan
system provides surveyors a choice of
operating any two of three frequencies
simultaneously using EdgeTech’s proven Full
Spectrum™CHIRP technology to provide
crisp, high-resolution side scan imagery. The
sub-bottom system incorporates up to four
deep-penetrating low-frequency DW-106 (1-
10kHz) transducers coupled with a PVDF
hydrophone receiver that provides excellent
sub-bottom receive sensitivity and directivity.
The 2300B system incorporates the
230/540/850 kHz side scan, sub-bottom profiler, and EdgeTech’s 540 kHz MPES Bathymetry. The Multi-
Phase Echo Sounder (MPES) produces real-time, high-resolution, three-dimensional (3D) seafloor maps
while providing co-registered simultaneous dual-frequency side-scan imagery. Additional 2300 system
features include a telemetry multiplexer, Discover software sub-bottom refection coefficient calculation,
built-in heading, pitch and roll sensors, and a rear magnetometer shackle mount. System options include
an integrated remote head USBL beacon, a mount for a customer-supplied Doppler Velocity Log (DVL),
and a magnetometer interface.

1.1 Key Features
The 2300 is a fully integrated deep-water capable side-scan and sub-bottom system that supports many
options.
Tri-Frequency Side Scan Sonar:A standard 2300 side-scan configuration is either a 120/410/850 kHz or
230/540/850 kHz that can operate any two frequencies simultaneously. The system frequency choice can
be instantly reconfigured, allowing the operator to react and optimize range and resolutions to changing
survey conditions and use the system in multiple roles.

Sub-Bottom Sonar: The 2300 system has enhanced sub-bottom profiling capabilities with multiple low-
frequency transducers and a PVDF receiver. The system mounts multiple transmit transducers in a 4 x 1-
10 kHz configuration, providing improved directionality and the ability to focus power where needed. 200-
Watt amplifiers drive each transducer and utilize wideband, Gaussian, and optional quadratic pulses that
emphasize the lower end of the frequency spectrum over a wideband pulse. The PVDF receive panel
provides 2D directionality and improved sensitivity over simple line arrays.
