Inside the triangle is your approximate current location. You should now have three lines drawn on your map, creating a small triangle where they cross one another. You can mark places in the Maps app with pins to help you find those places later. Repeat the steps you took to obtain a single back bearing for all three features you can see. It is possible to use just two features, but this will severely affect the accuracy of your pinpointing. The three features should be spread out, ideally with 120º between each (for example, one in front of you, one if you look over your right shoulder and the other over your left shoulder). If there are no man-made features use natural features such as the crests of hills, but be careful with trees and water, as these can change size and shape over time, making it easy to mis-identify them.

Where the line crosses the track you are on is your approximate current location. If possible, draw a line along the base plate. Ask: How easy or difficult would it be to pinpoint a location on a globe. Now carefully slide the compass across the map so one of the edges of the base plate crosses the feature you spotted on the landscape on the map. map and find the lines running across and up and. Line the orienting lines up with the eastings (the grid lines running north–south) on your map. The magnetic variation is currently 0º to 5º throughout Great Britain (this amount changes annually, so check your OS map to work out the most current value).
