SPECIFICATIONS

Name: North Needle
Color:  Green
Materials: Plastic shell, kerosene magnet, etc
Open size: 146X58X28mm Equivalent size: 77x58x28mm

Characteristics of American compass: pointing north, orientation, positioning, distance measurement, slope measurement (elevation angle), azimuth measurement, surveying ruler, magnifying glass, etc;
Damping dial: conducive to the stability of the pointer, more suitable for sports and rugged environments (slowly rotating when pointing, not insensitive);
Dial: The scale is accurate and clear, with a 360 degree azimuth angle division on the inner ring and a 64-00 precision division on the outer ring. The dial has a magnifying glass for a clearer view of the scale;
25000 meter coordinate ruler: convenient for measuring the distance between two points on a map, and also a powerful tool for geometric method mapping operations;
The arrow represents the N pole (North Pole), which is the annotation method for the majority of compasses.

matters needing attention:
1. Use in a horizontal state to ensure accuracy as much as possible;
2.To avoid confusion of the magnetic needle, please keep a certain distance from the wire mesh and objects containing magnetism when using it;
3. Do not use a surveying ruler to strike objects to avoid affecting measurement accuracy;
4. The disc and lens should be kept smooth and clean, and should not be wiped with dirty cloth or hands;



When not in use, it should be closed and placed away from ferromagnetic materials to avoid loss of magnetism
