1. [Optical Observation] Data can be read directly. The vertical baseline of optical observation improves accuracy and reduces errors. 2. [Fluorescent Design] The bright pink magnetic compass pointer allows you to read data when absorbing light in a dark environment. Sufficient sunlight. It is also a goniometer that can measure height and inclination. 3. [Multifunctional Metal Cover] The 360° foldable floating compass scale and the 360° adjustable lens prism are shock - proof and waterproof. 4. [Engineering Metal (High - Strength)] Suitable for use in extreme weather conditions and suitable for outdoor activities such as camping, mountain climbing, boating, exploration, hunting, hiking, and geology. Scale units on both sides: inches and centimeters. 5. Color: Military green. 6. Material: Metal. 7. Product size: Approximately 11 * 8 * 4 cm. 8. Product weight: Approximately 175 g. 9. Packaging list: 1x Compass, 1x English user manual. 10. Notes: - The compass should not be too close to the magnetic field, otherwise it will affect the pointer. - The light effect is related to fluorescent powder, fluorescent lamps, etc. Under natural light, the longer the irradiation time, the brighter the light display. Matte finish has no fluorescent effect. 11. Instructions for Use: - [Usage Conditions] 1. The product should be placed horizontally or held in the hand, and the direction and scale should be read as soon as the pointer or turntable is placed. 2. When testing the accuracy of the compass, place the products separately so that the distance between the compasses is greater than 20 cm and the distance from strongly magnetic products is greater than 30 cm to avoid magnetic interaction. 3. When using, keep away from magnets, mobile phones, metal objects, objects with strong magnetic fields or currents, otherwise it will affect the alignment of the compass and reduce its sensitivity. 4. Do not place the compass in direct sunlight or throw it away, or scratch the compass surface with sharp objects. - [Usage Method] 1. Please read the above usage terms first. 2. The turntable compass can directly read the scale of the turntable. 3. If you are using a turntable with an arrow, cover the end of the turntable. The red (there are also other colors, you need to ask which end is north before purchasing) and the "N" on the bottom dial can be used to read the direction. 12. [Note] If the product's environmental temperature reaches the maximum or minimum temperature specified above for a long time, it may cause the product label to deform, the body to crack, oil leakage, etc. Do not press the product during assembly, and do not change the appearance and structure of the product. 13. [Interview] - Place it in a ventilated and dry place, avoiding direct sunlight. - After use, pack it in a flannel bag to avoid scratching the compass surface. - If the surface is dirty, wipe it with a soft cloth to make it smooth. - Store it away from magnetic or current - carrying objects to avoid demagnetization.
