OTS MKII-Buddy Phone

The patented MKII-BUD Buddy Phone transceiver has an acoustic underwater telephone originally designed for professional Search & Rescue Teams. It is US Navy Approved and being used by many Government divers around the world. The MKII-BUD is configured for the all styles of Interspiro (IS) full face mask (FFM). Although it is still used with Search & Rescue Teams and Militaries commands, the Sport and Movie Industry are quickly standardizing on it. MKII BUD is well known throughout the world as the highest quality underwater communications system available.

MKII-BUD uses ultrasonic upper single sideband for transmission. The MKII-BUD Buddy Phone comes complete with a IS cover plate with Push-to-talk button, a patented HotMic (studio-quality, waterproof microphone), and the main transceiver.

How does it work? When the diver enters the water, the MKII-BUD/S powers up and cycles to the receive mode - ready to receive a message. When the diver/s want to transmit, they simply depress the PTT button located on the IS cover plate and talk. All divers and/or surface stations within range and on the same frequency will hear the message.

The MKII Buddy Phone has a nominal range of 164' to 1,640' (50M to 500m) depending on sea conditions and noise levels. Its transmitter output power is 0.5 watts PEP and standard frequency (PEP) recall & tone is A (channel 1) 32.768 kHz USB and B (channel 4) 31.250 kHz. The audio band width is 300 to 3,000 Hz and has an automatic gain control greater than 80 dB. The earphones and transducer are ceramic. It is powered by an alkaline 9V battery (not included). Includes an owner's manual.
