Suunto M-3 Global Sighting Compass, Adjustable Declination, Clinometer
The Suunto M-3 Global is the baseplate compass serious navigators reach for: a fast, jewel-bearing needle balanced to work anywhere in the world, adjustable declination so you can stop doing mental math, and a clinometer for judging slopes. It is light enough to forget about until you need it.

How it compares
Most compasses are balanced for one region and can drag or stick elsewhere. The Global needle works anywhere. If you want a sighting mirror for more precise bearings and signaling, the Suunto MC-2 Global adds one; the M-3 Global is lighter and flatter.
What owners and reviewers say
“The M-3G hits the sweetspot for extensive compass users.” Andrew Skurka
“The compass can be used anywhere in the world and the needle will remain steady when horizontal.” Chris Townsend, The Great Outdoors
Questions people ask
Do I need the Global version in North America?
Not strictly, but the Global needle settles faster and stays accurate when the compass is not perfectly level, and it keeps working if you travel to another part of the world.
How do I set the declination?
Look up the declination for your area on your map or online, then turn the adjustment with the small tool so the orienting arrow is offset by that amount. After that, bearings read true without mental math.
Do I need a mirror compass?
No. A baseplate compass like the M-3 is accurate for most navigation. A mirror model such as the MC-2 adds precision for long sightings and doubles as a signal mirror.
