Mechanical compasses have been working as the navigator since several thousands of years. Still today magnetic compass is environmentally friendly, cheap and the most reliable tool when choosing the course. The oldest Suunto field compasses, which are still in use, are manufactured in 1938. A high quality field compass hardly needs any other service than washing in fresh water from time to time. The compass works without any external power supply. The compass gets its power from nature – from the magnetic north pole.
