Why it works:
Dual inclinometers are the critical feature for snow safety professionals and mountaineers — slope angle measurement is essential for avalanche risk assessment, and having both a vial and lid inclinometer provides redundancy and flexibility in how you measure. 8-hour luminescence means the compass is fully functional before sunrise and after sunset without a headlamp. The TruArc Global Needle works on any continent without the needle drag that affects hemisphere-specific compasses.
Ideal for: Search and rescue teams, snow safety professionals, mountaineers, and serious backcountry navigators who need the most capable compass available. See also the TruArc 10 (BRU037) for a lighter adventure racing option.
