In this post we will learn how to determine our location on the map using any compass and a map protractor. But first let’s review Part 1, with a little different spin so the concepts will start to become clearer.
Part 1 discussed the many steps needed to read a bearing on a map using a typical baseplate compass. It also discussed how many fewer steps were needed to read a bearing using a map protractor. In both cases, we are adjusting our compass by compensating for variance between Grid North and Magnetic North on the compass. The only difference being that using a map protractor requires the user to truly understand how magnetic north relates to the map so the bearing can be adjusted using 3rd grade math.
In Part 1, we described how to take a bearing from a map using a map protractor and transferring it to a compass utilizing the
EAST IS LEAST, WEST IS BEST method.

I am going to show you how to navigate quicker and more accurately with a map and any compass, by using a map protractor.
Few subjects elicit more debates among hikers and backpackers than the subject of map and compass. Nowadays the subject includes GPS units, smart phones, base plate compass vs. fixed compass vs. lensatic compass, what map to use, etc. Then there is the fact electronic solutions (GPS and smart phones) can fail or end up with a dead battery. Many of the electronic persuasion carry and map and compass as a backup, which means duplicate items to do the same task, meaning unnecessary weight. Some of the backup maps and compasses in use are less than optimal and in a no-shit-need-to-have situation might be poor options (think button sized compass and a large scale general map).
We need to keep in mind that the goal of using a map and compass is to always know where you are, not figure out your location because you are lost. Of course, with practice you can use a map and compass to figure out your location if you do get lost.
Most backpackers bring a map and compass whether or not they know how to really use it. One piece of navigation equipment I rarely see in use by backpackers is a map protractor. In this post the protractor will be presented as a serious tool that backpackers may want to consider, and for those who have used and then abandoned a map protractor, perhaps a re-visit might be worthwhile.
