Review on Brunton F TRUARC15 TruArc 15 Compass by Ron Houston

I've compared this compass to several others and for some reason it reads 2.5 degrees east of magnetic north. I know it sounds crazy but it's true. I not only checked several other compasses, but several locations to avoid magnetic anomalies. I even asked some friends to check it out too. Now the mystery is why? It's just a magnetic needle. Some smart people still don't understand why. The rest of the design is desirable but doesn't read properly. I don't have to recommend it for that.
