Your compass has 3 graduations:
- A 5-cm graduated ruler
- A 1:25,000 scale
- A 1:50,000 scale
It will enable you to make measurements on your map and thus work on reading scales.
You will find a declination scale within the capsule.
The magnetic declination is the difference in angle between magnetic north and the geographical north on your map.
Find the value of this declination in your country on the internet.
Why use a wide needle?
When designing this compass, we chose a wide needle to enable a more accurate and intuitive visual alignment between the needle and the grid lines on the map.
For greater security and peace of mind, the neck strap comes with an opening system if snatched.
Oil bath - yes or no?
Rest assured: all Geonaute compasses are filled with viscous oil to ensure optimal performance.
