Review on 🧭 Unlock Your Orientation with the Brunton TruArc10 Baseplate Compass by Gerald Hill

Brunton's TruArc 10 is a bit disappointing. While capable of amazing accuracy, I'm convinced that whoever designed certain aspects of this compass never really needed to use it. To function properly as a ground plane compass, the body must be clear, with red lines on the underside that align with the map's north-south grid lines when the body is rotated to obtain map bearings. The underside of the compass case is covered with a white sticker and the only reference lines are on the numbered part of the compass dial. This makes fine adjustment extremely slow. The worst is the declination correction. I spent almost 45 minutes making this adjustment and I had to settle for a half degree offset because it was the closest I could get. Anyone who has developed this adaptation to the declination must examine his head. This compass really needs an adjustable declination that is gear driven. The compass needle works flawlessly and the 1 to 24,000 Roamer proved accurate and easy to use. The one degree bearing resolution is excellent for a compass of this size. One of the features a good ground plane compass should have is a built in magnifying glass to help you read contour lines from a topographical map. TruArc 10 does not have this feature, although there is a small magnifying bubble to make reading the bearing easier. It's also a little frustrating to only have a straight edge for determining bearings from a topographical map, only the right side is straight. It could have been a great compass if you put a little more thought into it.
