Why use a compass on the thumb?
There are a number of advantages to thumb carrying as soon as you start running while reading your map and compass.
It is easy to read the map and compass simultaneously, since the compass is always in contact with the map.
In addition, you can avoid the risk of getting snagged on a branch you face with a traditional cord and, if you fall, carrying a thumb compass means you can keep both hands free!
Rapid and stable needle:
A stable needle will allow you to read your compass while running and thus stay on course!
This stability is due to the special construction of the 'pivoting' needle.
In addition, a transparent stability disc reduces the unwanted vibrations of the needle, thus making it easy to read while running.
Lastly, the powerful magnet you can see under the needle enables a rapid reaction time.
Left or right thumb?
In general, right-handers prefer a LEFT-thumb compass and left-handers prefer a RIGHT-thumb compass; they can thus keep their stronger hand free to move branches aside, keep their balance or carry an electronic pointer to validate the control points.

Graduations: learn to do mental calculations!
The arrow at the top of the compass can help you find your position more quickly and easily on the map. The arrow is also graduated (3 cm), so you can quickly gauge the distances you will need to travel.
"So, 2 cm on the map, at a scale of 1:15,000, means 30,000 cm, so 300 m! You need to be good at doing sums in your head!"
Oil bath - yes or no?
Rest assured: all Geonaute compasses are filled with viscous oil to ensure optimal performance.
Balancing: can I use my compass all over the world?
This compass is balanced for use in the Northern Hemisphere.
Near the equator, or in the Southern Hemisphere, our compass will continue to indicate north, but its stability will be affected.
Our tips to ensure your compass lasts
Keep your compass in a place that is neither hot nor cold. Avoid excessively high or low temperatures and changes in pressure: high altitudes in the mountains or transport in the hold of an aeroplane.
After use, store the compass in the small, soft pouch provided to protect it from scratches.
