Feb 2, 2023 · The invention of the compass was a significant milestone in human history. Prior to its introduction, seafaring was a perilous endeavor, as sailors relied on stars, landmarks, and rough estimations to chart their course. However, with the compass, sailors gained a reliable tool that allowed them to determine their direction accurately.

The basics of compass usage are surprisingly simple and can be mastered quickly; and once learned they will certainly become an invaluable skill for any hiker, mountaineer, back country skier or suchlike outdoor enthusiast. However, if you are anything like most of us, chances are you have been packing a compass around for years, on your outdoor ad...
Let’s begin our introduction to compasses by taking a look at a standard, modern day, orienteering compass, and identifying its parts. As figure 1 shows an orienteering compass typically consists of three main parts: a magnetic needle, a revolving compass housing, and a transparent base plate. The magnetic needles north end is painted red and its s...
Before beginning to use a compass one should familiarize himself with basic directions and their degree readings. The four cardinal points are all 90 degrees apart, with East being at 90 degrees, South at 180 degrees, West at 270 degrees, and North at 360 degrees (or zero degrees). Identifying the degrees by 45 degree increments gives us the eight ...
One of the most important uses of a compass is taking, and following a bearing. A bearing is the direction from one spot to another, measured in degrees, from the reference line of north; in other words it’s one of the 360 degrees of the compass rose. To take a bearing hold the compass in front of you with the direction of travel arrow pointing at ...
A compass needle is influenced by the earth’s magnetic field which causes it to line up with magnetic north. Maps, on the other hand, are typically oriented to the North Pole (which is truth north). The difference between these two norths is called declination, and must be accounted for when using your compass in conjunction with a map. There are p...
As learned in the declination section, magnetic needles are affected by the horizontal direction of the Earth’s magnetic field. Bearing that in mind you might not find it surprising to learn that they are also affected by the vertical pull as well. You see, the closer you get to the magnetic north pole (located near Bathurst Island in Northern Cana...
It was mentioned early that one of the most important uses of a compass is for taking and following bearings. Equally important is using a compass to pinpoint your exact location on a topographic map. If you can look at a map and determine a line you are on, such as a road, hiking trail, or mountain ridge, you can pinpoint your location with only o...
Understanding Maps: To be truly strong at orienteering and navigation, one must become very familiar with maps, and the abundance of information they contain. Unfortunately, it would require a separate article to fairly explain maps, but it’s still worth looking at some map basics here. Know the scale of your map. All maps list their scales in the ...
Estimating Remaining Daylight: If you can see the sun and the horizon you can estimate the remaining daylight time. To do so, hold your hand up so it appears that your pointer finger is just touch the bottom of the sun. Then count the number of finger widths to the horizon. Each finger is worth about 15 minutes of time. For example, if you can fit ...
In summary, a compass is an invaluable tool that every outdoors enthusiast should understand how to use. Two of its main uses are to measure bearings, and to pinpoint locations. When working with bearings one needs to be aware of declination and how that causes map bearings and magnetic (field) bearings to differ. Remember it’s simply a matter of s...
Sep 24, 2024 · A compass is a device that indicates direction. It is one of the most important instruments used for navigation. Magnetic compasses are the best-known type of compass. While the design and construction of the magnetic compass have changed significantly over the centuries, the concept of how it works remains the same.

A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers.
Four Main Compass Directions (Cardinal Points): North (N) – This points to the North Pole and is usually shown at the top of maps. South (S) – Opposite to north, pointing towards the South Pole. East (E) – To the right of north; it’s the direction where the sun rises. West (W) – Opposite east, to the left of north, where the sun sets.

At night, place two sticks in the ground lined up with the North Star, with the taller one to the north of the shorter. Set your compass dial at 360, and point the direction of travel arrow north at the longer stick. Look at the compass needle, and note the difference between its bearing and true north, the difference is declination.
