A POWERFUL SOLUTION
Compass® Personal Voltage and Current Detector

Compass® is a light weight non-contact high voltage and current detector. Its advanced notification system is designed to quickly warn the user of the presence of voltage and current on a work site.

Once a field is detected, users are notified of the approximate distance and direction of the energized source. Compass will detect both overhead and underground high voltage sources.

  • Proximity Awareness of Danger
  • 360° Directional Alerts
  • Adaptive Sensing/New Baseline
  • Notifies 5x OSHA MAD
  • Customizable Management Setting
  • Easy-to-Apply Hardhat Attachment

Proximity Alerts
Rate and intensity of alerts increase as the user gets closer to danger.

Auto-Adaptive Sensitivity
Initializes in highest-sensitivity mode. Issues alert based on positive changes in the electric and magnetic field indicating an approaching energized surface. Briefly issues full notifications then adjusts to the current environment to eliminate further redundant nuisance alerts. Regains sensitivity as a ​threat gets farther away from the user.

Autonomous, Recurring Sensor Self-Test
The hourly self-test verifies that the sensors are operating correctly and accurately. Tests are done in the background to prevent any nuisance to the user. A heads-up-display will provide notification if the product is defective or is not working correctly.

Flexible Power System
The Compass™ personal voltage and current detector comes with a built-in rechargeable lithium-ion battery and uses a common 5V USB 2.0 Micro B charge point access. Compass™ has a 3-day battery life (non-frequent alerts), 12-hour battery life in rigorous activity (frequent alerts), charges in 1.5 hours, and has an easy-to-check battery life monitor. Typical battery life is 3-5 years before the reduction in charge capacity depending on use. 

Compass™ wearable voltage detector comes equipped with power-saving features such as automatically turning off when inactive (no motion) for 5 minutes. When threats are not detected, power functions are reduced to save battery.

Ideal Form factor
Compass™ wearable voltage detector is ergonomic and efficient. It’s small, low-profile housing clips underneath the hard hat brim out of direct line-of-sight of the user. The unit weighs 2 ounces and is 90 x 30 x 10 [mm] in dimension.

Industrial-Grade Durability
Operating Temperature: -29° C to 60° C (-20° F to 140° F)
Water Resistant: IEC IP6X (safe when exposed to heavy rain)
Physical Shock Certification
Military-grade components
