The magnifier is cut, bent and the surface treated in Sweden. It is designed to fit all thumb compasses of the major brands in the sport.
The material is aluminum so it becomes both durable, lightweight and comfortable to handle. All parts are made of material that is non-magnetic.
Are you orientated with a classic “plank”? No problem, the magnifier is designed to fit directly on the thumb of your compass-free hand with only a elastic band.
