Suunto M3 Global Compass
Includes a Free Grid Reference Tool and 1.1m Paracord Lanyard!
The Suunto M3 has been my mainstay compass for the last 8 years, I have used it everywhere from crossing Lake Fryxell in the Antarctic, to the extreme heat of the Makgadikgadi Pans in the Kalahari Desert and in Mountain Rescue, this is the only compass that Scott and I use.
I first experienced using the M3 whilst working with the Norrlandsflyg Search & Rescue Team, in Uppsala, Sweden. It was a freezing January night and the first thing that impressed me about the M3 was the luminosity of the needle, base-bars, bezel and index marker; far superior to any other compass I had ever used. The brightness and clear markings made it very easy to align the orienting lines with the compass needle, when taking a bearing and the large serrations on the bezel meant I did not have to take my gloves off to use it – a real bonus! Plus the Adjustable Declination Scale had been set to automatically account for the local Magnetic Grid Angle, eliminating the need to keep making allowances for it – a really neat idea.
Choose the Suunto M3 if you only intend to navigate in the Northern Hemisphere, or choose this 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.
- Global Balancing System
- Serrated bezel ring
- Jewel bearing
- Adjustable declination correction scale
- Base plate with anti-slip rubber pads and rounded edges
- Baseplate with magnifying lens
- Easy-to-read luminous markings help to use the compass in dark conditions
- Romer scales for grid references using 1:24 000 / 1:25 000 & 1:50 000 scale maps
- Ruler graduated in centimeters and millimeters
- Built in gravity operated Clinometer to measure slope angle – used to determine where you are on a hill and predict avalanche risk.
Suunto M3 Global 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, 1:24 000 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).
5. Luminous Base Marks
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 Mark
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. Anti Slip Rubber Pads
Allows the compass to grip the map whilst taking a bearing, making it less likely to slip thus helps keeps bearings more accurate.
10. Magnifying Lens
Ideal to check up-close those tricky little features printed on your map.
11. Clinometer Needle
To measure slope angle – used to determine where you are on a hill and predict avalanche risk.
With practice it is possible to take bearings of features using a baseplate compass to an accuracy of ±4°.
