Drive-By Voltage Indicator!
Don't Chase Faults Without It.
VoltWitch is an innovative drive-by voltage indicator that is installed in a line truck or utility vehicle like a radar detector. Instead of sensing radar signals, the VoltWitch senses energized overhead power lines.
The VoltWitch is ideal for trouble calls when you need to know if a line is energized or dead without leaving your vehicle.
Since the electric field surrounding an overhead power line propagates at the speed of light, it does not matter if the VoltWitch is traveling at 6 or 60 miles per hour to detect and display the presence of voltage.
The VoltWitch is also effective in emergency vehicles that need to know if an energized overhead power line is nearby.
