The Hot Stick has four (4) operational settings: Off, High, Low, and Front focused.
The HIGH setting increases the sensitivity and will alert the user sooner of the presence of an electrical hazard. As the voltage levels increase the device will begin alerting sooner as well.
While utilizing the Front focused setting, the device narrows the receiving area to the front focal area allowing to pinpoint the source.

The red striped area of the Hot Stick indicates the sensing section of the tool. The distance from a potential source at which the tool will begin to alert depends on several factors:
The setting mode of the switch
The magnitude of the AC voltage
The distance of the source
Possible shielding of potential sources
The size of the area where the AC voltage appears to be coming from, i.e., Wire(s) making contact with a metal building versus wire(s) making contact with a vehicle will provide different readings due to surface area that is energized.
