The Tempo 200EP-G is the tone probe techs standardize on: pair it with any tone generator and identify wires and cables without making metallic contact with the conductor. High gain (30dB nominal) and a powerful speaker pull the tone out of congested bundles and noisy equipment rooms, while the adjustable volume/sensitivity control narrows the field to the one pair you are hunting.

Field-smart details are everywhere: a resistive carbon-fiber plastic tip prevents accidental shorts while probing, the recessed spring-loaded button controls power and the high-power LED flashlight for working behind furniture and inside dim racks, and the audio-shock-protected 3.5mm headset jack saves your hearing on hot circuits. Recessed terminal ports accept a handset connection, and a single 9V battery runs about 50 hours.
