Overview
The Compass Series family includes three SKUs: Compass Core, Compass Pro, and Compass Pro IS. They share the same physical envelope (3.0" × 1.4" × 0.9", IP-67 enclosure) but differ in voltage-range coverage, sensitivity granularity, environmental ratings, and battery chemistry. Procedures and firmware packages are model- and hardware-version-specific — confirm the model before applying any guide.
At-a-glance comparison
| Capability | Compass Core | Compass Pro | Compass Pro IS |
|---|---|---|---|
| Weight | 0.95 oz (27 g) | 1.02 oz (29 g) | 1.02 oz (29 g) |
| Operating temperature | -20 °C to 60 °C | -20 °C to 60 °C | -20 °C to 50 °C |
| Battery | Li-Po 3.7 V / 250 mAh | Li-Po 3.7 V / 250 mAh | Li-ion 3.7 V / 85 mAh |
| Typical battery life | ~6 days (48+ hrs) | ~6 days (48+ hrs) | ~2 days (16+ hrs) |
| Voltage ranges | Medium only | Low / Medium / High | Low / Medium / High (no Low settings 8–11) |
| Voltage sensitivity levels | 2 (settings 6 and 11) | 11 + Smart Adaptive + Alert Disable | 11 + Smart Adaptive + Alert Disable |
| Current sensitivity levels | 1 (setting 11) | 11 + Smart Adaptive + Alert Disable | 11 + Smart Adaptive + Alert Disable |
| Smart Adaptive Mode | Not available | Yes | Yes |
| Hazardous-location ratings | — | — | UL / CSA / IEC 60079-0 and 60079-11 (see Pro IS Annex) |
Charging is the same across the family: typically 1.5 hours to 100% from a USB source delivering at least 5 V / 0.5 A; charging temperature 0 °C to 45 °C.
Compass Core
Entry-level model with reduced sensitivity granularity and the Medium voltage range only. No High Voltage Range and no Smart Adaptive Mode. If a procedure references "all 11 sensitivity settings" or Smart Adaptive, it does not apply to Core.
Compass Pro
Full sensitivity range (1–11), Smart Adaptive Mode, Alert Disable, and all three voltage ranges: Low (120 V AC – 2.4 kV AC), Medium (2.4 kV – 34.5 kV), High (34 kV – 500 kV). Voltage range is selected in Navigator Mobile, not on the device.
Compass Pro IS
Intrinsically safe variant carrying UL 60079-0 / 60079-11 / 61010-1, CSA C22.2 #60079-0 / 60079-11 / 61010-1-12, and IEC 60079-0 / 60079-11 ratings. Operating temperature is reduced to -20 °C to 50 °C, the battery is smaller (Li-ion 3.7 V / 85 mAh, ~2 days of typical use), and the Low Voltage Range omits sensitivity settings 8, 9, 10, and 11. The Compass Pro IS Annex is the authoritative document for hazardous-location use.
High Voltage Range generations
Pro and Pro IS High Voltage Range behavior changed in 2025. Devices identified in Navigator Mobile as V4 and prior use first-generation tuning; V5+ uses second-generation tuning with extended detection distances. Compass Pro IS units are all V5+. Compass Pro 60 Hz units (M03006) built before week 28 of 2025 are first-generation; Pro 50 Hz units (M03008) built before week 26 of 2025 are first-generation. The split matters when comparing field experience across older and newer hardware in the same crew.
