Some variables with which you must be aware are:
Proximity devices are supposed to detect the existence of electricity
Some proximity devices will detect only alternating current (AC) -
not direct current (DC).
Some devices detect radio frequency (RF) energy - others do not.
Most proximity devices simply provide a signal (audible, visual, or
both ) for the operator - the signal must not be ignored.
Sometimes the sensing portion of the proximity devices becomes
confused by complex or differing arrays of power lines/sources.
Plan ahead and plainly mark a safe route before traveling under power lines.
