1 1.2 Main System Components
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.
1.3 4125-P Portable Topside Processor
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.
