Suunto MC-2 Compass Review (and Giveaway)

After finishing another Wilderness Navigation Course today for the Appalachian Mountain Club in Pinkham Notch I decided it was finally time I post a review on the one piece of equipment I have carried in the mountains for over two decades. My compass, the Sunnto MC-2.

The compass is the 2nd piece of equipment listed in the often referred to “Ten Essentials” and is a must for anyone heading to the mountains for a bit of adventure. A great gear list for hiking & backpacking can be found here on

Since this piece of equipment is so important it’s wise to put a little thought into your choice. For the money, I have not found a more fully functional compass that can do as much as the Sunnto MC-2 anywhere, which is why I have happily replaced mine three times in the last 20 years when I misplaced (or loaned) it to someone and never got it back.

Without getting into the intricacies of accurate map & compass work I want to call out exactly what sets this compass apart in the field.

Sighting Mirror

How important is a sighting mirror? Depending on the range to your target the sighting mirror can play a significant role in accurate bearing reading. It allows you to hold the compass at eye level and arms length and still read the information given on the dial/bezel. Two “sights” are present, a higher “gun notch” and a level gap below the mirror, so you have better accuracy based on relative elevation to your target. I find I can get a bearing 3-4 degrees more accurately with this style than a regular “base-plate” type compass. In my lectures I compare the accuracy of this style compass to a rifle aimed from the shoulder vs. a pistol fired from the hip. A sighting mirror is more accurate hands down. It also has the added benefit of being an excellent signal mirror for search and rescue aircraft and allows me to easily put my prescription contacts in on multi-day trips!

Extended Baseplate

While technically an off-shoot of the sighting mirror the fact that a fully opened Sunnto MC-2 can cover 7 inches across a map makes it really convenient for taking bearings and plotting location with known points (re-section & triangulation). These skills, when used with smaller base-plate compasses, often involve estimation, map folding, or the use of a straight edge to get an accurate reading. With the Sunnto MC-2 plotting on a map is simple.

Large clear dial


The orienteering lines are highly visible under the bezel/dial, making accurate measurement possible from any north-south lines on the map or along the edge of the map.

A clinometer measures slope angle. This is extremely important for those travelling in avalanche terrain as a difference of 5 degrees of slope can often mean the difference between a slope being stable  or unstable. Savvy mountain travelers in avalanche terrain are constantly checking slope angle, and to do so accurately one needs a clinometer. The Sunnto MC-2 has one built in that can function on the slope like the photo above, or in conjunction with the sighting mirror while looking up or down a slope.

The above photo of me measuring slope angle was coincidentally taken moments before a human triggered size-able avalanche caught 5 people on Mount Washington. One of the people caught is just disappearing out of the safer area we where at before the incident occurred. My write up of this incident is here.

Adjustable Declination

The Sunnto MC-2, like many top tier compasses, allows one to set the magnetic declination for the area of operation. I am not going to dive into a detailed conversation on declination in a gear review but simply put this is a solid feature for a vast majority of recreationalists and mountain professionals. There are many professionals out there that feel it is almost required. Since I teach courses to people with various pre-owned compasses my personal opinion is if one truly wants to understand solid map & compass work one needs to be able to navigate with an adjustable or non-adjustable compass. That being said, the fact it is an option on this compass is win-win, I just choose not to use it.

Magnifying glass

A small feature, but helpful none-the-less! This feature really helps when decoding small print & icons on a faded map!

1:24k and 1:62500 scales

The Sunnto MC-2  has two distance scales along the side calibrated to the two most popular USGS map scales. Combined with the included lanyard it should be quite easy to accurate estimate distances on your maps.

In case you want some manufacture specifications here they are:

  • High grade steel needle with jewel bearing
  • Balanced for northern hemisphere
  • Adjustable declination correction
  • Liquid filled capsule for stable operation
  • Mirror for sighting bearings and signaling
  • Sighting hole and notch for accurate bearings
  • Non-luminescent bezel
  • Clinometer
  • Luminescent markings for working in low light
  • Metric scales and inch ruler
  • Baseplate with magnifying lens
  • Detachable snap-lock lanyard with wristlock. Easy to detach for working with the map
  • Suunto limited lifetime warranty
  • Made in Finland
There is little improvement to suggest on such a well crafted piece of outdoor gear. For global travel Suunto does offer a slightly more expensive global version but for anyone staying in the northern hemisphere you can pick this compass up at a great price on Amazon right here. Using that link will help support this blog and earn you karma and increased karma means less chance of getting lost*.

    Hoping to win this, but if I don’t I’ll be purchasing one. Today’s Wilderness Navigation 101 course was a blast! As a newbie to hiking (a year now), it was awesome to go off trail with a sense of confidence because we had learned the basics of compass and map usage. I’d brought a military-grade compass with me, which we agreed would survive a mortar hit and probably be useful in detecting ground fire with great accuracy, but the compass was useless for setting a course with a map. Looking forward to a tool that I can actually put to use in New England!

    If I was ever lost in the woods or on a mountain top in the worst weather conditions you can imagine I would want to be with David Lottmann. I came to this conclusion after I took a course called Wilderness Navigation 101 through AMC taught by Dave. His knowledge of navigating safely through the outdoors is incredible and I feel fortunate that I was able to take his class. I will be looking for more classes taught by him. Regarding the class, I knew somewhat on how to use a compass, but after the class that included a really cool bush whack I feel much more comfortable, knowlegible or maybe the word is empowered with my new abilities using and reading a compass and the other navigation tricks David taught us. But of course I will not forget to give Mother Nature great respect. Anyone looking to enhance their abilities in the great outdoors should take this and other courses taught by Dave.

    Best regards,
    Andrew Papalegis

    It was through your class that I learned my compass was useless! Still need a good one🙂

      Well you might just win one through this contest! And if you don’t there’s usually a low priced one at the links I provided in the review!

    Hi Dave,

    Nice to hear you are encouraging people to you such a high-quality compass. Suunto makes about the best compass for backcountry users!
    I teach wilderness navigation for the Mazamas mountaineering club in Portland Oregon. I have a mac Keynote presentation, converted to PDF, that I call the wilderness navigation challenge, that is an instructional series of questions and answers about key navigation skills. It would be great if you can have a look at this and get back to me with your feedback. I’ve shared it with several other navigation instructors recently, and it made some helpful suggestions. It is a PDF file on my shared Google Drive, and you can see a link to it from the Mazamas website below.
    Please let me know what you think, and feel free to share it with anyone else you know that might find it useful. > resources > navigation training
