An elongate probe of at least 2 feet in length for alerting a user to the presence of electrical energy includes an antenna to sense radiated electrical energy and an indicator to alert a user when activated. Circuitry determines when the sensed electrical energy meets a user adjustable threshold and activates the indicator when the sensed electrical energy meets the user adjustable threshold. An adjustor allows for selecting the user adjustable threshold.
