4125 Series Applications
S
The EdgeTech 4125 Series Dual-frequency Side Scan Sonar System is a frequency-modulated (FM), dualfrequency, side scan sonar that uses EdgeTech’s proprietary Full Spectrum “chirp” technology to generate
high-resolution, side scan imagery at longer ranges than conventional continuous-wave (CW) systems.
The system is designed primarily for search and recovery operations, along with surveys in shallow water.
The 4125 Series is available in two, dual simultaneous frequency configurations depending on the
application: 400/900 kHz and 600/1600 kHz. For shallow water survey applications, the 400/900-kHz
frequency set is the best choice, as it provides an ideal combination of range and resolution. For ultrahigh resolution imagery at shorter ranges, the 600/1600 kHz set is the recommended choice.
In both configurations, the frequencies are transmitted as linearly-swept, wide-band, high energy acoustic
pulses, and the received echoes are processed into high signal-to-noise (SNR) images that can be directly
displayed as shades of gray or color on a computer monitor. The SNR images can also be printed on a
continuous feed thermal printer, or stored in real time onto a large capacity hard drive and archived onto
a DVD.
Applications for the 4125 Series Dual-frequency Side Scan Sonar System are many, including:
x Hydrographic surveys
x Geological surveys
x Search and recovery
x Channel conditioning/clearance surveys
x Bridge, pier, and harbor wall inspections
x Hull inspections
x Port security
x Archaeological surveys

4125-P Portable Topside Processor
Figure 1-1: Readying the Towfish for Deployment
1
The 4125 Series Dual-frequency Side Scan Sonar System is composed a 4125-P Portable Topside Processor,
a 4125 Tow Vehicle (commonly called a Towfish), and a tow cable. These components are shown in Figure
1 2.
In addition, the tow vehicle is available with or without the additional telemetry option, which enables
the use of longer tow cables. Without the additional telemetry option, tow cables up to 150 meters in
length can be used. With the additional telemetry option, the system will perform with cable lengths up
to 600 meters. Contact EdgeTech Customer Service for the specific cable types.
The 4125-P Portable Topside Processor is shown in Figure 1-2. It provides power and downlink telemetry
to the tow vehicle for sonar control and receives uplink side scan data, sensor data, and status information
from the tow vehicle for processing, storage, and display.
The topside unit includes a laptop computer with Windows 7 and the EdgeTech DISCOVER 4125 Side Scan
Sonar software preinstalled. DISCOVER 4125 provides control, storage, and display of the sonar data. The
data can be stored in XTF and JSF formats.
4125 SIDE SCAN SONAR SYSTEM 0004823_REV_C

1.4
Tow Vehicle
The 4125-P Portable Topside Processor interfaces with the tow vehicle either over a direct 10/100BaseT
connection or, with the additional telemetry option, over a 10BaseT connection that uses very high bit
rate digital subscriber line (VDSL) modems. The topside unit also interfaces with a global positioning
system (GPS) over a USB to serial or RS-232 serial interface.
The topside processor integrates tow vehicle and DC power supplies, an ETHERNET switch, a wireless
router, and, with the additional telemetry option, an VDSL modem, all housed within a single, compact,
rugged, water-tight (when closed) Pelican Storm Case. It runs on either AC or DC power, and interfaces
with the laptop computer over a wired or wireless 10/100BaseT ETHERNET connection. The computer can
be stored inside the enclosure when not in use.
CAUTION!
Never attempt to use the portable topside’s storm case as a shipping
container. Doing so could void warranties and/or result in system
damage.
1
The 4125 Tow Vehicle is available with a choice of 400/900 kHz or 600/1600 kHz operating frequencies,
and with or without the additional telemetry option. It contains the sonar transducer arrays and the
electronics required to transmit and receive the sonar signals; to receive the downlink commands from
the topside processor; and to provide the uplink side scan data, sensor data, and status information to
the topside processor.
The electronics are contained inside a single, lightweight stainless steel, 200-meter depth-rated housing,
comprising the aft section of the tow vehicle. The forward section is flooded and includes both the port
and starboard transducer arrays. A single O-ring sealed end cap is attached to each end of the housing to
seal it, and the forward end cap contains bulkhead connectors for connecting to the transducer arrays. An
adapter cable also connects to this end cap.
The cable snakes through a hole in the transducer array section and includes an inline connector for
connecting to the tow cable. The tow vehicle interfaces with the topside processor either over a
10/100BaseT ETHERNET connection, or (with the additional telemetry option only) over a 10BaseT
connection that uses VDSL modems in both the tow vehicle and the topside processor.
The tow vehicle is also equipped with four stabilizer fins, a stainless steel nose for hydrodynamic balance,
and two convenient carrying handles. A towing arm is rigidly mounted to a tow point on the top of the
tow vehicle housing adjacent to the tow cable connector. The tow cable attaches to a shackle on the
towing arm.
Additional mounting holes are provided on the tow point should it be necessary to reposition the towing
arm forward or aft to adjust the balance of the tow vehicle. The towing arm also includes a safety release
1-4
mechanism, which causes a shear pin to release the tow point should the tow vehicle hit an obstruction
or become snagged. If this happens, the tow vehicle will rotate nose down, and a safety cable, which is
attached from the tow point to the rear of the tow vehicle, will pull the tow vehicle over the obstruction
or through the snag, stern first.

The 4125 Series Dual-frequency Side Scan Sonar System includes a 50-meter tow cable, terminated at
both ends. The tow cable is used both to connect to the tow vehicle, and to tow it behind the survey
vessel. Tow cables are available as either a Kevlar-reinforced six conductor or an RG-58 coax cable, which
includes a single conductor and a shield.
The coax cable is used only for systems that include the additional telemetry option. Up to 150 meters of
6 conductor cable or 600 meters of coax cable can be used. Contact EdgeTech Customer Service for
available cable lengths other than the supplied 50-meter cable. A cable grip is also included for attaching
the tow cable to a shackle on the towing arm of the tow vehicle.
Optional equipment that can be installed and used with a 4125 Series Dual-frequency Side Scan Sonar
System includes:
x Additional telemetry (specified when ordering tow vehicle)
x Keel Weight Kit (p/n 0008464)
x Depressor Wing Kit (p/n 0007860)
x HullScan Kit, W/O Telemetry (p/n 0008478)
x HullScan Kit, W/ Telemetry (p/n 0008477)
x Over the Side Mount (p/n 0007633)
The additional telemetry option increases the maximum
length tow cable that can be used from 150 meters to 600
meters by using VDSL modems to establish the
communications link between the tow vehicle and the
topside processor instead of a direct ETHERNET connection.
Contact EdgeTech Customer Service for the specific cable
types.
The Depressor Wing Kit provides a depressor wing (shown in Figure 1-3) that can be attached to the tow
vehicle, allowing it to be towed deeper and faster without increasing the length of tow cable in the water.
The depressor wing attaches to the top of the tow vehicle and pushes it deeper by exerting a downward
force on the tow vehicle as it moves through the water. A safety cable with a shear pin mechanism is
attached to prevent loss of the wing should it become snagged.

The Keel Weight Kit provides an additional 15 lbs. of weight to the tow vehicle.
Two HullScan Kits are available, W/O Telemetry and W/ Telemetry. Each of these kits enables a tow vehicle
to be inverted such that the transducer arrays are angled upward instead of downward. In this
configuration the tow vehicle can be used to scan the hulls of ships. The HullScan W/O Telemetry kit is for
tow vehicles that do not have the additional telemetry option. The HullScan W/ is for those that do.
This option allows the towfish to be mounted on a pole for shallow water survey or for vertical imaging.
