  6. Magnetic North Pole The magnetic and geographic North poles are not the same! The magnetic NP is moving from the Canadian to the Russian Arctic at a rate of 40 miles a year The Earth’s Magnetic Field

  7. The red needle on a compass points to Magnetic North

  8. Parts of a Compass

  9. YouTube - Taking a Compass Bearing Setting a compass bearing

  10. 1. Line up the side of the base plate with the direction you are interested in on the map 1. Reading a bearing from a map

  11. 2. Turn the compass wheel until “N” and the red orienting lines on the base of the wheel are parallel with the blue grid lines on the map. • Read the grid bearing on the main central red direction of travel line on the compass 2. Set the Grid bearing on the compass

  12. For GRID to MAGADD! At the moment in this part of the country you add 2 degrees 3. Convert the Grid bearing to a Magnetic bearing(because a compass points to Mag north, not grid north) so if the Grid bearing is 277° the Magnetic bearing will be 277°+2º=279º Now turn the dial so that it reads 279º

  13. Direction of Travel Arrow 4. Remove the compass from the map, hold it level in front of you so the compass needle is free to turn. Turn your body until the red compass needle (magnetic north) lines up with the red orienting arrow on the base. Using the direction of travel arrow, sight a distant landmark and move towards it. 4. Follow the Magnetic bearing

  14. From 333 047 to 342 046 • From 319 076 to 324 086 • From 315 036 to 324 042 Now try taking these Grid bearings and try pointing towards the Magnetic bearing. As well as finding the bearings for your route cards, estimate the distances to the nearest 0.1 km (remember 1 blue grid square is 1km or 1000m wide)

  15. From 333 047 to 342 046 • From 319 076 to 324 086 • From 315 036 to 324 042 Answers
