RX-100 Buddy Phone®

STX-100 Buddy Phone® 

BUDDY PHONE® ULTRASONIC TRANSCEIVER SXT-100 BUDDY PHONE®

  • The XT-100 Buddy Phone® transceiver has been specifically designed as an underwater acoustic telephone for the Sport Diver. It is a buddy system providing moderate range and clear diver-to-diver voice communications. With an optional surface station, diver-to-surface and/or surface-to-diver communications are available.
  • The XT-100 Buddy Phone® includes the following: electronic module with earphone and transducer, HM-2 silicone mouth mask, uniquely designed flood able microphone (installed in the HM-2), comfortable silicone head strap, easy adjustment buckles and users manual.
  • The XT-100 comes installed on the HM-2 head strap. The user simply removes the bite mouth piece from their 2nd stage regulator and replaces it with the HM-2 mouth mask. Install a 9 volt battery and don the HM-2. The user then adjusts the straps to fit and dons their face mask.
  • Once in the water, the unit automatically turns ON and goes into the receive mode. Any Buddy Phone® or Aquacom® signal ,within range and on the same frequency, will be heard. To transmit, simply depress the patented push-to-talk control located on the HM-2. As long as the button is depressed, the XT-100 is transmitting. All other Buddy Phones® within range and on the same frequency will receive the message.
  • Buddy Phone® was designed as a diver-to-diver, "Buddy System". The depth capability is within the range of safe scuba diving standards.
  • RX-100 Buddy Phone® is a RECEIVE ONLY unit. It is designed to be used with standard scuba equipment. It simply attaches to the existing face mask strap and positioned over the ear. It is powered by a single 9 volt battery.
  • The RX-100 Buddy Phone® will monitor communications from all single sideband, Aquacom® and/or Buddy Phone® transceivers within range and on the same frequency.
  • RX-100 Buddy Phone® is a great tool for instructors, tour guides, directing photography, or just sharing with a friend.
  • The STX-100 Buddy Phone® Surface Station is a multi channel surface station designed to operate with all ultrasonic transceivers operating on the same frequency (i.e. SSB-2001, SSB-2010, MKII-BUDS, XT-100, RX-100, etc.).
  • STX-100 is dependable and manufactured to the highest standards. You can compare this unit to any surface station on the market. It will match or exceed all others! It operates on standard Alkaline "C" cell batteries, offers front panel Squelch, and lots more. The only small thing about it, is the price!

 MKII BUDDY PHONE® - INTERSPIRO FULL-FACE MASK

  • MKII Buddy Phone® and the Interspiro full-face mask (FFM) is a perfect combination. The Interspiro FFM is used by Military, Commercial, and Scientific professionals as well as Search & Recovery teams around the world. It is also popular with many "Technical" divers.
  • The high quality 2nd stage regulator was proven to be one of the best in recent U.S. Navy tests. It is a demand type regulator. On demand, the air flow travels across the face lens keeping it defogged. The air flow also cools your face before it enters the comfortable oral nasal cavity. Since you have no regulator in your mouth, jaw fatigue is completely eliminated. The ability to breath through your nose alleviates dry mouth. We offer the MKII-BUDS installed in a GOLD, silicone FFM standard. However, the Buddy Phone can be purchased separately and configured for virtually any style FFM.
  • The oral nasal cavity is the perfect place for our specially designed, high quality, diver microphone. A port located on the front of the FFM allows microphone positioning in front of the users mouth ensuring clear communication. The Buddy Phone® transceiver mounts nicely on the side of the Interspiro FFM.
  • The combination of high quality communications and one of the finest full-face masks available, ensures virtually the highest intelligibility possible.

    SSB-2010 & CDK-6 Surface Accessory Kit

 

 The Aquacom® SSB-2010, SSB-1001B and SSB-2001 can easily be converted to a portable surface station allowing surface-to-diver and/or diver-to-surface communications. The CDK-6 consists of a high grade headset with boom microphone, a Hi-Use connector and 55' of transducer cable.

To make the conversion you simply connect the headset with boom microphone to one of the above transceiver's Hi-use connector. Step two is to disconnect the transducer from the transceiver. The transducer is connected to the 55' transducer cable. The other end of the transducer cable is connected to a transceiver. The transducer cable will override the transceivers water activation switch and the unit will power up. Lower the transducer into the water and you are in business. Additional transducer cable is available from your local dealer if necessary.

The CDK-6 uses a custom-made headset with boom microphone. The microphone can be positioned at virtually any angle. The microphone element is noise canceling and can easily be replaced.

The SSB-2010/2001/1001B gives you the option of utilizing itas a portable surface station or diver transceiver. The best of both worlds!
