A measuring device measures distances via a thin retractable wire with a removable head. Distance is calculated and displayed on a very bright, large LED or other type screen. As the wire is extended, a microprocessor calculates the distance and displays it on its screen. The digital measuring device comprises a housing, a very thin extendable wire, cable or tape, a rotating spool, (from which the wire extends then automatically retracts to), a sensor which measures the amount of wire extended, a microprocessor, a tiny flash drive or other type of memory storage, a microphone/speaker, a large (size of unit) mono or duo chromatic or other type of display screen (LED) and a few buttons and/or a menu driven interface which control functionally. A plurality of removable heads may be attached to the wire for performing different measuring functions.
