Name: DC45-2A-2B North Arrow
Color: Army Green
Material: aluminum alloy shell, plastic, kerosene, magnet, etc.
Open size: 146X58X28mm Reduced size: 77x58x28mm
●American north arrow features: pointing north, orientation, positioning, distance measurement, slope measurement (pitch angle), azimuth measurement, mapping ruler, magnifying glass, etc.;
●Damp dial: Conducive to the stability of the pointer, more suitable for sports and rugged environments (slowly turn when pointing, not insensitive);
●Dial: The scale is accurate and clear, the inner circle is 360-degree azimuth division, the outer circle is 64-00 dense division system, the dial has a magnifying glass, you can see the scale more clearly;
●1: 25000m coordinate ladder: It is convenient to measure the distance between two points on the map, and it is also a powerful tool for operations on the geometric method map;
●The arrow indicates the N pole (North Pole): It is the marking method for most north arrows.
Precautions:
1. Use in a horizontal state to ensure accuracy as much as possible;
2. In order to avoid confusion of the magnetic needle, please keep a certain distance from the barbed wire and objects containing magnetism during use;
3. Do not hit the object with the surveying ruler, so as not to affect the measurement accuracy;
4. The disk surface and lens should be kept smooth and clean, do not wipe with dirty cloth or hands;
5. It should be closed when not in use and placed away from ferromagnetic materials to avoid loss of magnetism.
