Adjusting the declination on your BRUNTON TruArc 5 Compass ensures accurate navigation. Here's how: First, place your thumb in the center of the liquid-filled vial and pinch the vial with your forefinger at the bottom, through the opening in the center of the base. Next, keep the rotating dial steady with your other hand. Twist the liquid-filled vial within the outer dial until the red hash mark at the tail of your magnetized needle aligns with your specific declination setting. This setting is determined by your geographical location. Once set, the BRUNTON TruArc 5 Compass automatically compensates for declination, helping you find your way with precision.
