The SP-100D Surface Buddy PhoneÞ is designed. State-of-the-art Digital Signal processing circuitry (DSP - known as "Software DefinedRadio") has been incorporated ensuring great performance and clarity.

The user simply places the SP-100D 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-100D Surface Buddy Phone.
The SP100D Surface 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 utilized. You can monitor and talk to divers while the action is happening.
