OTS Buddy Phone D2 in-water transceivers for full face mask

OTS Buddy Phone D2

Using "digital signal processing" (DSP) techniques, the Buddy Phone produces uncompromised voice clarity. The Buddy Phone® D2 differs from our standard Buddy Phone in that it is digitally controlled and has fantastic features such as: a voice menu to guide you adjust your volume, switch from channel A to channel B, or put the Buddy Phone in continuous voice transmission mode.

Voice menu: when you dive with a D2 Buddy Phone, you will hear the voice system say "Buddy Phone ON, frequency A (B), channel one (four), volume high (medium, low)", depending on the previous dive. Settings. Changing a setting is easy and can be done underwater. Press the Push-To-Talk (PTT) button three times quickly, and hold the third press until you hear "main menu - volume, channel, continuous transmission". When you hear the main menu selections, simply press the PTT to select one of the choices. The unit will make the selection and return to receive mode. If you do not make a selection after the menu repeats twice, the D2 Buddy Phone exits the main selection menu and returns to receive mode (see the operator's manual for a more detailed explanation - note: the continuous transmission mode allows the user to talk, hands free. This has been requested by many filmmakers and scientists who talk to the camera often).

Overall, this D2 friends phone is state-of-the-art and OTS technology at its best.
