4125 SIDE SCAN SONAR SYSTEM 0004823_REV_C
1
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.
