The distance of the AC Hot Stick of which it can detect simply depends on how high the voltage is and how large of an area is exposed, and not covered by any shields that may be grounded. For example a "hot" 7500v overhead power line can be picked up from approximately 60 metres away, however a vehicle in contact with 12vac can be detected from approximately 2.5 metres.
The setting of the AC HotStick detection mode on the unit also will vary the detection range. AC Hot Stick uses an audible beep and visual LED which will increase in rate or decrease whether the user gets closer or further from the voltage source.
