I am looking for a hands free, non-PTT that can listen and talk to surface and other divers. Where do I look?
Hello Fleet, all the communication units are the PTT. If there was no PTT then everyone would only hear you. At this time no manufacture makes a hands free version of the underwater communication. Now if you are only looking to listen and not have the option to talk you could use the: http://www.scuba.com/scuba-gear-168/027690/Ocean-Reef-GSM-Dual-Channel-Communication-Unit.html.
OR033135 - Ocean Reef Alpha Pro X-Divers Underwater Communication Unit
Waterproof piezoelectric speaker
Full duplex system
Audio/video recall button
By adding an additional surface/diver cable and underwater unit, the Alpha Pro X-DIVERS may communicate with two
divers at the same time. It is also possible for the surface to switch between each of the divers.
(Possible configurations: surface/diver 1, surface/diver 2, surface/diver 1/diver 2. If the unit is set for surface/
diver 1/diver 2, the two divers would also be able to communicate with each other.)
