When an item is lost, just press its corresponding button on the portable radio-frequency transmitter base and carry it from room to room. The receiver disc flashes and beeps with varied cadence when the base gets within 40 feet of the wayward item. The base comes with a magnetic mounting bracket that attaches to a metal surface, such as a refrigerator or a filing cabinet. The base unit itself will start beeping if it hasn't been returned to the bracket within six minutes. Cool!
