SAFEGUARD Compass, Personal Voltage & Current Detector

COMPASS® from Safeguard Equipment is a personal voltage & current detector that senses exposed electricity and alerts the user long before they are in danger of being electrocuted. This life-saving device displays the distance and direction of the threat, and it’s the only personal detection device that can sense current.

The Safeguard COMPASS® mounts under the brim of any standard hard hat within the user’s peripheral vision. This strategic placement allows it to provide 360° detection around the user. When a threat is detected, COMPASS® immediately provides the user with both audible and visual notifications.

SAFEGUARD Compass, Personal Voltage & Current Detector


COMPASS® alerts users to any change in nearby electric and magnetic fields. It features seven levels of sensitivity as well as Smart Adaptive mode, which adjusts to its current environment to eliminate redundant alerts and then resume if the user moves closer to the energized source.


The COMPASS® personal voltage and current detector comes with a built-in rechargeable lithium-ion battery and uses a common 5V Micro-USB charge point. COMPASS® has a 10-day battery life, charges in 1.5 hours, and has a typical life of 3-5 years before any reduction in charge capacity.


COMPASS® is IP 67 water-resistant and can operate at any temperature from -20° C (-4° F) to 60° C (140° F). It’s made with polycarbonate ABS material with UV resistance additives. In addition all COMPASS® devices include up to a 1-year warranty.


COMPASS® self-tests its sensor accuracy multiple times per hour. Tests are done in the background to prevent any nuisance to the user, and the heads-up-display will provide immediate notification if any issues are detected.


COMPASS® is designed to be ergonomic, efficient, and intuitive with a slim low-profile housing that clips underneath the brim of any hard hat and provides LED alerts that are bright & distinct without impeding the user’s direct line of sight.
