The transmitter is attached to the object, an in use, transmits radio frequency signal multi-directionally, while the receiver wirelessly detects the signal. The receiver has a directional reception area such that the signal strength received is maximum when the angle between the transmitter and the reception area is about zero degree. Upon determining the direction of the transmitter, the user may further move the receiver in the same direction to locate the transmitter and the object. Indicators such as LEDS and buzzers are provided to indicate signal strength. The rotation of the receiver in two or three dimensions is automated.
