Compass Pro Wearable Voltage Detector

Detection and emergency response from one device.

The full connected wearable voltage detector. One 22-setting scale covers 120 V to 500 kV with both adaptive modes, and falls, impacts, arc flash, and SOS go straight to your response team through Navigator.

Compass Pro voltage coverage

Voltage coverage

Compass Pro detects 120 V – 500 kV AC on a single sensitivity scale, with no separate voltage ranges to select.

Where Compass Pro fits

Compass Pro is what most organizations standardize on when they want prevention and response from one device. Crews get detection in their peripheral vision; safety leaders get emergency events with location routed into Navigator instead of a phone tree.

What Compass Pro does

120 V to 500 kV, one scale

One device follows a worker from a service call to a transmission structure, with no voltage range to select.

Direction, not just proximity

The corner LEDs sweep toward the source, then both ends of the bar flash once the worker is facing it, accurate to roughly ±20°.

Current detection in blue

The same escalation pattern in blue, across 11 current settings. With the handheld adapter, it also traces conductors inside walls.

Emergency events, raised and cancellable

Impacts, falls above 6 ft (1.8 m), and arc flash raise an event automatically, with 30 seconds for the worker to cancel a false alarm. Holding SOS for 3 seconds raises one manually.

Adaptive alerting

Work Zone Adaptive holds the zone you set. Smart Adaptive tracks the ambient field. Transit covers moves between sites. Crews are not choosing between nuisance alerts and silence.

Compass Pro specifications

Compass Series is intended as a secondary voltage detection method only. It supplements, and never replaces, a qualified electrical safety program, permits, lockout/tagout, and PPE. Always test against a known voltage and current source before field use.

Detection ranges and sensitivity

Voltage coverage120 V AC – 500 kV AC
Sensitivity scale22 settings across the full span
Adaptive modesSmart Adaptive and Work Zone Adaptive
  • Voltage and current are configured separately. Voltage runs all 22 settings and current runs 11. Both support the adaptive modes and Alert Disable.
  • A setting means the same thing on every connected device and every hardware generation, so crews can compare readings directly.
  • Sensitivity can be changed on the device with the MAIN button or in Navigator Mobile.
  • Max Alert distance is approximately 60% of First Alert distance. A First Alert at 10 ft (3.0 m) corresponds to a Max Alert near 6 ft (1.8 m).
  • Admins can lock specific options through Compass Pro Configurations in Navigator Console. Applied configurations take effect once the user acknowledges them in Navigator Mobile.

Detection is affected by extreme humidity, materials that shield electromagnetic fields, brisk walking speed, and three-phase systems that can cancel fields in certain areas. Warning distances also vary with the conductor’s exposed surface area, its elevation above ground, and its proximity to other grounded conductive objects.

Part numbers

Part numberDescription
M01012Compass Pro kit, 60 Hz
M01009Compass Pro kit, 50 Hz

Compass Pro ships as a kit in 50 Hz and 60 Hz variants. Match the SKU to your grid frequency. Frequency is built into the detection tuning and is not a field-changeable setting.

The event reaches someone who can act on it.

An impact, a fall, an arc flash, or a 3-second SOS hold opens an emergency event in Navigator with the worker’s location on the map. Safety leaders see it on the web console, and responders get it on the phone, without anyone working down a call list.

Fits how your crews already work.

Hard hat brim as standard, plus non-brimmed helmet, Petzl Vertex, IDRA 2, adhesive, and SECRA-1 adapters, and hot stick, wrist, and collapsible handheld options.

Compass Pro questions, answered

What voltage can Compass Pro detect?

Compass Pro covers 120 V AC to 500 kV AC. Following the Consolidated Range Release, that span is covered by one 22-setting sensitivity scale, so there is no longer a Low, Medium, or High voltage range to select in Navigator Mobile.

What is the difference between Compass Pro and Compass Core?

Both cover 120 V to 500 kV AC. Compass Core has two voltage sensitivity settings, one current setting, and no adaptive modes. Compass Pro runs the full 22-setting scale with both adaptive modes and Alert Disable. Both share the same enclosure and battery.

Does Compass Pro require a subscription?

Voltage and current detection work without one. Emergency events on Compass Pro require an active Navigator Respond subscription. Respond is the Navigator tier that includes the emergency response system (ERS). Without it, Compass Pro detects hazards but does not raise, send or coordinate emergency events.

How long does the Compass Pro battery last?

The 3.7 V / 250 mAh Li-Po cell runs about six days (48+ hours of use) per charge and recharges to full in about 1.5 hours from a USB source delivering at least 5 V / 0.5 A. Battery life varies with how many alerts the device generates.

What triggers an emergency event on Compass Pro?

Downward impacts severe enough to cause a concussion, falls greater than 6 ft (1.8 m), and light characteristics consistent with an injury-level arc flash all create events automatically. Automatic events run a 30-second countdown the worker can cancel before the event is sent. Holding the SOS button for 3 seconds creates one manually. No motion for 60 seconds after an event elevates it to worker-down.

What do the V4 and V5+ hardware versions mean?

Detection at the top of the voltage span was retuned in 2025. Units identified as V4 and earlier use first-generation tuning; V5+ uses second-generation tuning with extended detection distances. Sensitivity settings themselves now mean the same thing on every generation, so the hardware version affects detection distance rather than how a setting reads. Check it on the Navigator Mobile Tools tab.

Which Compass Pro part number should I order?

Order M01012 for 60 Hz systems and M01009 for 50 Hz systems. Grid frequency is built into the detection tuning, so it cannot be changed in the field.
