Underwater communication system
EAR MICROPHONE
Sea to Sky Dive Technologies
Includes two bone conduction earphones, two earphone holders, waterproof microphone and VOX / Push to talk switch. Divelink's VOX (Voice-activated) system automatically isolates human speech from bubbles and ambient noise, and effectively activates only when the diver speaks. When no one is transmitting, the unit is silent. Our competitors offer "VOX" systems that are actually noise activated resulting in time-consuming calibrations and considerable unwanted noise invariably making it necessary to use a PTT (push-to-talk) button in order to transmit.
