A handheld tester that measures cable length (up to roughly 100,000 feet / 30km) and low resistance by sending a pulse down the conductor and calculating distance from the reflection. It offers 20 built-in cable-type presets plus 8 user-programmable slots to match different wire gauges and insulation types, a large backlit LCD with switchable feet/meter readout, and a fold-out kickstand for bench use. Ships with test leads, a reference copper rod, and a carrying case.
