Use the compass on a flat surface or by holding your hand steady. Keep it away from magnetic fields (phones, speakers, magnets, electrical devices, etc.), as they may affect measurement accuracy. Ensure the needle moves freely during use. When determining direction, hold the compass at chest level and keep it level. Do not drop it, as impact may affect measurement accuracy. Although it is waterproof, do not expose it to water for long periods. Keep it out of the reach of children; it is not a toy. Use a dry or slightly damp soft cloth for cleaning; avoid chemical cleaning products. For long-term storage, keep it in a dry place away from moisture. Compass
