Finding Your Way Without Map or Compass. Harold Gatty

Finding Your Way Without Map or Compass. Harold Gatty
During his remarkable lifetime, Harold Gatty became one of the world's great navigators (in 1931, he and Wiley Post flew around the world in a record-breaking eight days) and, to the benefit of posterity, recorded in this book much of his accumulated knowledge about pathfinding both on land and at sea. Applying methods used by primitive peoples and early explorers, the author shows how to determine location, study wind directions and reflections in the sky, even how to use the senses of smell and hearing to find your way in the wilderness, in a desert, in snow-covered areas, and on the ocean. By observing birds and other animals, weather patterns, vegetation, shifting sands, patterns of snow fields, and the positions of the sun, moon, and stars, would-be explorers can learn to estimate distances and find their way without having to rely on a map or a compass. The wealth of valuable data and advice in this volume ? much of it unavailable elsewhere ? makes it indispensable for hikers, bikers, scouts, sailors, and outdoorsmen ? all those who might find themselves stranded or lost in an unfamiliar area. Through careful study of this book and its lessons, pathfinders can learn to interpret signs in the natural world to find their way in almost any kind of terrain.

What is a Global Needle?

Before you can fully understand a "Global Needle", you must understand a few basic principles of a compass. In order to get an accurate reading from a compass, the compass needle needs to be "balanced" in the capsule, so it does not drag on the top or bottom of the capsule. But, because the horizontal and vertical components of the earth's magnetic field vary considerably in different locations, a compass needle that "balances" perfect in North America will drag or stick in South America. As a result of these magnetic variances, the compass industry has divided the earth into 5 "zones", as identified in the map below. All of the standard compasses sold at The Compass Store are balanced for zone 1 (since most of our sales are in North America).
...
But, what if you're not a world traveler? Why would you want a global needle? Well, the global needle's unique ability to handle tilts up to 20 degrees makes it perfect for hikers that don't want to break their stride. Not having to level the compass exactly makes it easier to take an accurate reading while you're still moving along the trail.
