The RX-100 Buddy Phone® Receive Only unit is designed as an acoustic underwater listening device to be used with all Buddy Phone® or Aquacom® transceivers within range and on the same frequency. The diver simply attaches the RX-100 to his own face mask and is ready to go. When the diver enters the water, the RX-100 powers up and cycles to the receive mode—ready to receive a message.

The RX-100 is the most powerful tool an Instructor or Tour Guide can use. It allows verbal communications helping the new diver feel more secure.

The RX-100 is compatible with all OTS through water communications systems (surface and diver) and receives on Channel 1.
