Quick Answer
To determine True North using a compass, turn the compass until the directional arrow points towards the magnetic needle, which should be aligned with the magnetic north. The bezel or rotating ring should be set to the current magnetic declination for your location, and the compass should be held level and away from any metal objects.
Setting Your Compass
To set your compass, hold it level in your non-dominant hand, with the directional arrow pointing towards the magnetic north. For most countries, the magnetic declination is close to zero, but it can be significant in areas near the magnetic poles. Check your local magnetic declination by consulting a map or compass manufacturer’s website.
Finding True North
Once your compass is set, rotate the bezel until the magnetic needle aligns with the directional arrow. The bezel should be set to the magnetic declination for your location. This will give you a reading that is close to True North. However, for precise navigation, it’s essential to know the exact magnetic declination for your location.
Tips for Using a Compass in the Field
When using a compass in the field, always hold it level and away from any metal objects, such as your belt buckle or watch. Avoid using a compass near power lines, generators, or other sources of electromagnetic interference. It’s also essential to know the correct magnetic declination for your location and to regularly update it, as it can change over time.
