HeliCom™ dive control unscrambler
The Divex HeliCom™ dive control helium speech unscrambler is designed for helium speech communication with three divers and the bell environment.
A front panel loudspeaker allows the diver's speech to be audible to the diving supervisor, independently of his headset, in all modes of operation. An on/off switch allows the loudspeaker to be switched off as required.
