A portable electronic price label locator (24) which uses signal strengths associated with signals from the electronic price label (18 or 19). The locator includes a keypad 54 to input information identifying the label to be located, and three spaced RF sensors (70) to receive signals from the label. From the relative strengths of the received signals processing circuitry (60) determines the direction to the electronic price label, which is displayed on a display (62) as an arrow pointing right or left.
