V-Watch™ Personal Voltage Detectors

V-Watch personal voltage detectors by HDE (HD Electric Company)

The V-Watch alerts you to the presence of electric fields around electrical equipment. Provides another level of safety for line crews, storm restoration workers, first responders and all users who work close to electrical equipment.


  • Audible and visual alarms. Increase in frequency the closer the user gets to energized equipment.
  • Typical V-Watch initial warning distance is about 7 feet (2.13 m) from a 4kVAC conductor. Warning distance increases with higher voltages.
  • It comes with an electrically screened cover that blocks the electric fields when the personal voltage detector is not being used.
  • Low battery indicator.
  • Field replaceable 9V battery.
  • Rugged protective housing.
  • Built-in self test.
  • Lightweight.
