EMS Electronic Sounder

The standard Clifford & Snell sounder is equipped with a VHF radio transmitter - for regular reporting purpose but receives command signals from the controller on the more powerful UHF 459 MHz frequency. This reduces the signal time by ensuring more direct communications. 
Audibility is 96 dBA at 1 metre. With auto-shut off (adjustable) pre-programmed for 30 minutes.

Radio sounders can be supplied in weather-resistant housing.
