Compass Personal Voltage & Current Detector


Compass™ is a smart, innovative, life-saving device that detects energized sources and warns users long before they are in danger of being electrocuted. It alerts users of their proximity to a threat and then informs them of the direction of the source. Its intelligent design allows it to be configured to best provide protection within the environment of almost any work situation. It is the first of its kind.

Compass™ is engineered to attach easily to the underside brim of any standard hard hat. Positioned within the user’s peripherals, it provides ease of use and functionality. This strategic placement allows it to provide a 360° detection area around the user. Once a threat is detected, Compass™ immediately provides the user with both audible and visual notifications.

LineStar is the EXCLUSIVE dealer for the compass in Canada.
