Comms Rope

What it does

Braided 4-core Communications Rope for Diving Applications

Image Gallery


The C-Tecnics super-flexible, low diameter, comms rope is ideal for commercial divers using full-face masks such as AGA Divator masks. The comms rope is interwoven is such a way that the strain is not put on the 4 communication wire but onto the rope, reducing the breakage potential of the comms wires. The rope also provides extra safety as a recovery line with a breaking strain of 650kg and also used to communicate with the surface using pull signals. The comms rope can be terminated with any electrical connector, but is normally stocked with the ‘marsh marine style’ of 4 pin connector.
