The guide needle must be held horizontally, and stay away from the various items listed below, so that the magnetic needle should be chaotic: the guide should be 10 meters away from the wire mesh, the high -voltage line is 55 meters, the car and the aircraft are 20 meters, and the magnetic container contains 10 meters.Essence
Use the compass to explore the steps where you are now:
① Make the actual terrain and map direction consistent.
② Find two visible targets on the map.
③ Pay the line (or long side) of the compass towards one of the targets
④ Find the circle with the arrow number and pointer (north).
⑤ Do not change the direction of the circle to place it in the north position of the map.
⑥ The long -sided tip of the compass matches the target on the map.
When the arrow of the circle and the magnetic North Line extended line draw a straight line.
⑧ For the same method for another goal.The staggered part of the two lines is the current location.
Use the compass to explore the direction of advancement
① Make the line (long side) of the straight line of the current position and destination.
② The arrow and magnetic North Line of the circle are parallel (the arrow is on the top of the map).
③ Take the compass from the map and hold it in front of the body.
④ Turn your body until the arrow and pointer overlap.
⑤ The direction of overlapping the line is equal to the target direction of the map.
