The Wire Tracker™ Wire Tracer by Sperry Instruments extends a much needed improvement to a classic wire installation tester. This tone and probe kit has a variety of integrated adapter cables that are neatly hidden away when not in use, ensuring they will not be lost or damaged. The probe can also be nestled within the unit when not in use, completing a very secure instrument. Unlike many other similar products, the sensitivity of the receiver probe is adjustable for the ultimate accuracy in identifying individual wires.

Fragile tip

  • Easy To Use
  • Many Test Leads


  • Flimsy Construction
  • Not A Very Strong Signal

Best Uses

    I do a lot of ethernet and phone wiring and need to tone out lines all the time. I purchased one of these units and the tip broke off within 3 months. I thought it was just a simple production error so I purchased another one to replace the broken one. Three months later the tip broke off THAT one! I won't be purchasing another one and am questioning the quality of Sperry overall.
