Suunto M3 NH Compass for the Northern Hemisphere

Includes a Free Grid Reference Tool and 1.1m Paracord Lanyard!

Unlike Lyle, I rarely get to visit the Southern Hemisphere; even leaving my beloved Scotland is difficult for me 😉 So when Lyle brought back the M3 GLOBAL and asked if I wanted to try it I was reluctant. Not just that I really do not need a global compass, moreover, that I was very happy with my Silva Expedition Type 4 that I have used for years. We were on a training exercise with the team, Tweed Valley Mountain Rescue, that involved navigation at night, above St Mary’s Loch in the Southern Uplands of Scotland. The first thing that struck me was the luminosity of the bezel and compass needle, much brighter and clearer than my Silva and it came into its own when I donned my gloves.

That week I bought the less expensive model, the M3, balanced for the northern hemisphere (all compasses need balancing for different regions, with the exception of the M3 GLOBAL). This is genuinely the best compass I have ever used and I am never without in mountain rescue.

Choose the Suunto M3 NH if you only intend to navigate in the Northern Hemisphere, or choose the Suunto M3 Global if you are going to navigate anywhere in the world (including Western Europe) as it is balanced to work across the globe; otherwise these compasses are identical except for the clinometer on Global model.

Suunto M3 Northern Hemisphere Features

Suunto M3 Northern Hemisphere Features

1. The Baseplate
The mounting of the compass with anti-slip rubber pads, a ruler in centimetres plus scale rulers for measuring distance on map sizes 1:50 000, 1:25 000, 1:20 000 and 1:15 000.

2. Luminous Compass Needle
A one-zone magnetic needle that pivots on a jewel bearing and is surrounded by liquid so it can rotate freely and smoothly: the red end always points to magnetic north.

3. Luminous Serrated Bezel Ring
A rotating bezel which has the cardinal points and the azimuth of 360° marked on it in 2° increments. 4 orienting lines Rotate with the bezel and designed to be aligned with the map grid (the blue lines that run top to bottom of your map).

4. Orienting Lines
Rotate with the bezel and designed to be aligned with the map grid (the blue lines that run top to bottom of your map).

5. Luminous Base Dots
Need to be aligned with the compass needle (red north) to take a bearing (which can then be read on the index triangle).

6. Luminous Index Triangle
This is where you read the bearing.

7. Direction of Travel Arrow
shows the direction that you want to travel along or the bearing you are taking.

8. Adjustable Correction Scale
Can be set to automatically correct for magnetic declination.

9. Stencil Holes
Allows you to accurately make marks on your map with a grease pencil.

10. Magnifying Lens
Ideal to check up-close those tricky little features printed on your map

With practice it is possible to take bearings of features using a baseplate compass to an accuracy of ±4°.
