REED Instruments Continuity Tester

This continuity tester is capable of checking circuits for continuity and identifying cables and wires up to 10,000 ft. (3,000 m) in length. Bright visual (bi-color LEDs) and loud audible (beeper) indicators allow wire ends to be tested in noisy environments. The R5300 is used by professional electricians, alarm/cable installers and in home audio installations.
