Like the AT-2004, the Amprobe AT-2005 Wire Tracer traces live wires buried or hidden behind walls up to 13 feet (4 m) thick without interrupting power.
However, the AT-2005 electrical wire tracer also includes a battery booster that strengthens the signal for more accurately tracing opens and finding wires in walls. The AT-2005 is used for quickly locating breakers, broken wires, neutrals, grounds, shorts and pinpointing ground faults.
