The OCEAN REEF GSM G.divers wireless underwater transceiver is designed to enhance safety and enjoyment during training, guided dives, and group outings. Lightweight and powerful, it offers single-channel "push-to-talk" communication with a claimed range of 200 to 250 m in calm water and a battery life of approximately 30 hours in reception mode.
Compatible with the same frequency as other OCEAN REEF devices (and most wireless systems on the market), the GSM G.divers operates with a 9V alkaline battery and includes a low battery alarm (beeps every 30 seconds) for peace of mind underwater.
For installation on the extension frame, the NACS™ (Neptune Adjustable Communication Support) system is required and sold separately.
