MARK Compass Skills
The baseplate compass is the most reliable navigation tool you can carry. Unlike GPS, it never runs out of battery, loses signal, or fails in cold weather.
A standard baseplate compass is all you need for UK hill walking (common brands are Silva, Brunton, or Suunto).
How to Take a Bearing
Step by Step
- Place the compass on the map with the direction of travel arrow pointing toward your destination.
- Rotate the bezel housing until the orienting lines align with the north–south grid lines on the map (red north arrow pointing up).
- Hold the compass in front of you and turn your body until the red magnetic needle sits inside the orienting arrow.
- You’re now facing your target.
Trust It in the Mist
In mist or darkness, trust the compass over your instinct. The human brain easily walks in circles without visual references.
Magnetic Variation
Magnetic variation in the UK is currently small and easterly — around 0 degrees in the south-east rising to 2–3 degrees east in north-west Scotland, and it shifts slightly every year. It’s negligible for most practical navigation, but always check the declination diagram on your map to be exact.
MX Summary: A compass is the one navigation tool that never lets you down. Learn to take a bearing, and trust it when the world shrinks to a few metres of visibility.
