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 towfish, and to tow it behind the survey vessel.
Tow cable is a RG58 coax cable which includes a single conductor and shield.
Up to 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 towfish.
