The SP-100 Surface Buddy Phone® transceiver was designed to operate with all single sideband acoustic underwater devices within range and on the same frequency. The user simply places the SP-100 Buddy Phone® in a secure area, lowers the 35' transducer cable in the water, turns the power On and talks via a hand held microphone. All divers and/or other surface stations within range and the same frequency will receive the message. When any other persons within range and on the same frequency talks, the voice will be heard from the front panel speaker of the SP-100.

The SP-100 Buddy Phone® is compact and operates on 8 AA Alkaline batteries ensuring hours of fun. For those who require extreme long life, two battery packs (16 AA) batteries can be utilzed. You can monitor and talk to divers while the action is happening. A must for all dive boats and/or dive operations.

  • Designed with State-of-the-art Digital Signal Processing circuitry ensuring great performance and clarity
  • Front Panel speaker allows any persons within range and on the same frequency to be heard loud and clear
