An object locating system (10) usable by an intended user (11) for locating an object (44), the object locating system (10) comprising: a first transmitter-receiver unit (12) including a first unit transmitter (100) for selectively transmitting at least one of a first search signal and a second search signal, a first unit receiver (102) for receiving a third search signal and a first unit signaling element (104) operatively coupled to the first unit receiver (102) for issuing a first alarm perceptible by the intended user (11) when the third search signal is received by the first unit receiver (102); a second transmitter-receiver unit (14) including a second unit transmitter (100) for selectively transmitting at least one of the first search signal and the third search signal, a second unit receiver (102) for receiving the second search signal and a second unit signaling element (104) operatively coupled to the second unit receiver (102) for issuing a second alarm perceptible by the intended user (11) when the second search signal is received by the second unit receiver (102); a receiver unit (116) including a third unit receiver (106) for receiving the first search signal and a third unit signaling element (108) operatively coupled to the third unit receiver (106) for issuing a third alarm perceptible by the intended user when the first search signal is received by the third unit receiver (106). The first transmitter-receiver unit (12) is configured and sized to be wearable by the intended user (11) and the receiver unit (16) is securable to the object (44). The first and second transmitter-receiver units (12 and 14) are usable by the intended user (11) to locate each other and are each usable by the intended user (11) to locate the receiver unit (16).
