The Ocean Technology System (OTS) RX-100-D2-A Buddy Phone is a receive only unit designed as an acoustic underwater listening device to be used with all Buddy Phone or Aquacom transceivers within range and on the same frequency. To use the OTS RX-100-D2-A Buddy Phone, the diver simply attaches the RX-100-D2-A to his or her own face mask by positioning the phone right over the ear and is ready to go. When the diver enters the water, the RX-100 powers up and cycles to the receive mode only - ready to only receive messages. The OTS RX-100-D2-A Buddy Phone has a new squelch which only allows signals at a specified strength over a threshold to be played over the speaker. This helps decrease bubble and marine biological noise. The OTS RX-100-D2-A is the most powerful tool an instructor or underwater tour guide can use. It allows verbal communications helping the new diver feel more secure.
