Search & Rescue

OTS offers a complete line of Full Face Masks (FFMs), through-water transceivers, hard wire communications units, and support items designed to meet the needs of the Public Safety Diver.

When determining whether or not the diver should use hard wire or through-water communications, consider the following:

  • Hard wire communications is the highest quality, most intelligible form of communications. Signals are transmitted via 2 or 4 wires securely housed inside of a braided nylon rope.
  • While distances of through-water communications have exceeded 6 km, it is highly dependent on sea conditions, underwater obstacles, and turbidity. Hard wire distance is limited to the length of ComRope being used.
  • Full Face Masks configured with Earphone/Microphone assemblies can be used with either hard wire and/or through-water communications units.
