7. Ensure the rope and/or cable grips are being used as the tension member and no strain is being placed on the connectors of the cable. 8. If a cable and rope are being used, it is beneficial to tape or cable tie them together every few meters. Tow Fish User Guide April 2020...
4. Place the Tow Fish in the water maintaining control over the towline. 5. To adjust the Tow Fish depth, have the vessel slowly transiting and pay out the rope to a desired length (anticipate 5:1, rope length to depth ratio).
Find an X (cross) on the cable where you will begin an under-over pattern, under the first X cross and over the next cross continuing until returning to the first X to connect the cable tie. Tow Fish User Guide April 2020...
13. This length should ideally be less than the depth of the water to ensure the tow fish will not be dragged along or hit the bottom damaging the equipment.
