Recover the price in no time!!!
Do you like to change batteries? Do you need any transmission when nobody is home? Or at sleeping time? No, it's just a battery waste. 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.
All the components are Military Specs, the best and precise ones on the market. It's a piece of art design !
