Martindale VT3 is a non-contact voltage and magnetic indication from 200 V to 1000 V. Accurately detects the presence of AC voltages in wall sockets, wires and cables, circuit breakers and electrical panels. Eliminates any potential danger of working on a live circuit.

A red light illuminates the tip and the unit gives an audible signal when AC volts are detected. A green light illuminates to show the presence of a magnetic field. Ergonomic design with safe, non-slip finger grip. Easy to use and small enough to fit in your pocket.
