3.7.1 Connecting and Attaching the Tow Cable to the Towfish
While a Kevlar cable supplied by EdgeTech can support the weight of the towfish, to increase the life of
the tow cable it is recommended to tow the tow fish using a suitable rope or cable to support the weight
of the tow fish. For shallow water surveys, a tow rope with a working load of 2,000 lbs. or more and a
breaking strength of at least 6,000 lbs. can be used to tow the towfish. It should also have an eyelet for
attaching to the shackle on the tow bridle of the towfish. A safety grip should also be used to strain relieve
the tow cable. For deeper surveys, and armored cable should be used to tow the towfish.
To connect and attach the tow cable to the towfish:
1. Verify that the tow cable is not connected to the 2000 topside computer.
2. Verify that the tow cable connector on the towfish and the mating female connector on the tow
cable are free of corrosion or dirt. If dirty, clean with an alcohol wipe.
3. Apply a thin film of silicone grease to the pins of the tow cable connector on the towfish.
4. Mate the connectors by pressing them firmly together. Do not wiggle the connectors.
5. Secure the connector locking sleeve.
6. Attach the eyelet of the tow rope and the loop of the safety grip to the shackle on the towing arm
and secure the shackle bolt with seizing wire or a tie wrap.
7. Secure the tow cable to the tow bridle and properly stress relieve the connection and splice.
