Two powerful modes in one tool

Mode I turns the unit into a Power Circuit Probe Tester with four working modes: AC/DC Voltage, Resistance, and Diode checks. It clearly indicates live status and which side of the circuit you are on, without external power banks. It can be powered by cigarette lighter or vehicle battery, so you can work while parked or on the go.

• Powered by cigarette lighter or vehicle battery
• No external battery needed for the main mode

Breaker finder and non-destructive wire tracing

Switch to Mode II to locate breaker points, open connections, and wires without damaging insulation. Works across cars, SUVs, trucks, boats, RVs, and more, with DC voltages from 6 to 42V.
