The rim of this wheel extends all the way to your horizon. With compass in hand, imagine you're at the hub of a gigantic wagon wheel. Now that you're back, let's pick up again by looking at. We'll get back together in a few minutes. Be sure to watch the video about declination. Take some time now to visit that page and come to understand this concept thoroughly. You can't learn how to use a compass effectively without understanding the ins and outs of declination. Land navigators call this difference " magnetic declination," which is covered on the page just highlighted. In most places on the earth there is a difference between magnetic north and true north, that is the direction to the true geographic North Pole.
Allowed to float freely, a compass needle aligns itself with the earth's magnetic field, making one end of it appear to point to magnetic north. Without those cues, it's hard for us to know up from down, much less north from south or east from west.Īn important cue for us can be the compass needle, which is merely a magnetized piece of metal suspended in some way so it can float freely. Some animals may have it, but we two-legged, big-brained creatures are dependent on cues from our surroundings to find our way. The main reason you as a land navigator need to learn to use a compass is because we humans have no built-in sense of direction. The purpose of a compass is to orient you with regard to direction. Rather watch and learn than read and learn? In my online video-based land-navigation course, you'll learn to use an orienteering compass and a lensatic compass.
But get the stuff down on this page before you leave.
The pages related to the use of those compasses branch off of this page, and are hyperlinked below. This page sets the stage for you then to go on to learn specifically how to use both the orienteering compass and the lensatic compass. This section's purpose is to help you learn how to use a compass for effective land navigation. Using a Map and Compass in Florida's Big Cypress Swamp
