What Happens If You Drop Your Compass in Water?

Question

Accepted Answer

Water Damage and Corrosion Water damage and corrosion are the primary concerns when a compass is submerged in water. Magnetic compasses, in particular, are susceptible to corrosion, as the ferromagnetic materials used in their construction react with water. This can lead to a weakening of the magnetic field, causing the compass needle to become inaccurate or even stick. The extent of the damage depends on the duration and depth of the submersion, as well as the type of compass and materials used. As a general rule, a compass submerged in water for more than 30 seconds may experience significant damage.
Desiccation and Drying If you’re able to retrieve your compass quickly, you may still be able to salvage it by drying it out. However, this process requires great care, as moisture can seep into the compass’s mechanisms and cause further damage. To dry your compass, gently pat it with a soft cloth or paper towel, and then place it in a warm, dry environment, away from direct sunlight. Avoid using heat sources, such as hair dryers or ovens, as this can cause the internal mechanisms to warp or crack. It’s essential to dry your compass slowly and carefully to prevent further damage.
Restoration and Maintenance If your compass has been severely damaged, it may require professional repair or replacement. In some cases, you can clean and maintain your compass to prevent future damage. Regularly inspect your compass for signs of wear and tear, and store it in a dry, secure location when not in use. Clean your compass with a soft cloth and mild soap solution, and apply a thin layer of silicone-based lubricant to the pivot point to keep it running smoothly. By taking these precautions, you can extend the lifespan of your compass and ensure it remains a reliable navigation tool.
