The DACS uses OCEANEARS underwater speaker technology to allow divers to communicate without the need to wear a receiver.
All surrounding divers within range will hear the VOICE transmissions. The system is simple and utilizes the following:
(1) KIRBY MORGAN Full Face Mask with waterproof microphone
(2) Power amplifier, transformer and 12 VDC battery installed in waterproof PVC Housing mounted on side of tank with pony bottle mount.
(3) PUSH to TALK SWITCH -- Unit only consumes power when PUSH to TALK is pressed to power up the system.
(4) OCEANEARS Underwater Speaker to project voice transmissions into the water.
