Compass

Magnetic navigation instrument for finding direction without batteries or signal. The most reliable navigation tool that exists.

Why It Matters

GPS devices run out of battery. Phone signals disappear in remote areas. A compass always works. Combined with a map, it’s the foundation of outdoor navigation that has guided people for centuries. In poor visibility — fog, darkness, whiteouts — a compass may be your only way to navigate safely.

Features to Look For

Baseplate design
A clear baseplate with ruler markings lets you take bearings directly from a map.
Luminous markings
Glow-in-the-dark cardinal points for navigation in low light.
Declination adjustment
Lets you compensate for the difference between magnetic and true north.

Common Mistakes

Holding near metal objects
Zips, phones, and knives deflect the needle. Hold the compass well away from metal.
Not practising before you need it
Learn to take a bearing in your local park, not when you’re lost on a mountain.
