Adjustable declination is the reason the MC-2 is our top pick, and it is the feature most shoppers do not know to look for. Magnetic declination — the angle between magnetic north and true north — can run past 15 degrees in the Pacific Northwest, which is more than enough to put you on the wrong side of a ridge. A small key on the lanyard lets you dial your local variation into the compass once; after that, every bearing you read is a true bearing, with no arithmetic to do in the rain. That is the difference between a compass you consult and one you trust.
The rest of the instrument backs it up. The mirrored lid has a sighting notch and a hole, so you line the hairline up on a landmark and read the bearing in the reflection — we found that steadier than holding a baseplate at eye level, and the mirror doubles as a signal mirror if you ever need one. Suunto balances the needle for global use, so it will not drag when you travel, and there is a clinometer for slope angles. It is made in Finland on a composite body and weighs 4 ounces.
What you accept for that is a learning curve. Our first few attempts had the sighting line and the reflection fighting each other, and the bearing came out crooked until we got the eye position right; a few rounds on a familiar landmark sorted it. The composite body keeps the weight down, though it does not feel as dense in the hand as the metal lensatic compasses here.
Small details matter on a navigation tool. The lanyard has a wrist lock, so you can let the compass hang while you fold a map on a windy ridge without watching it slide off your wrist.
Pros
- Adjustable declination ends the mental arithmetic
- Mirror sighting gives a steadier bearing
- Needle balanced for global use
- Wrist-lock lanyard keeps it on your hand
Cons
- Luminous dial needs charging before night use
- Long body at nearly 5 inches
Buy the MC-2 if you want one compass that gives a correct bearing anywhere without mental math, in a pack you already carry.
