Do you like to change batteries? Do you need any transmission when nobody is home or at sleeping time? No, it's just a waste of battery and money. This professional transmitter preserves the battery for long time, as the current on "standby" is about 0.8mA - almost nothing!!! When someone begins to speak, the transmitter begins to transmit. A special audio filter make it more sensitive than ever to human voices. A small LED added so you can know when it transmits and for frequency adjustment if needed.
All the components are Military Specs, the best and precise ones on the market. It's a piece of art design !
