Quick Answer
A good survival compass for long-distance hikes is one that is precise, durable, and reliable, with a clear dial and luminous markings for low-light visibility, magnetic declination adjustment, and a stable base plate.
Key Features of a Good Survival Compass
When selecting a survival compass, consider the following essential features: a precise magnetic needle that can be adjusted for magnetic declination, a clear and legible dial with luminous markings, and a sturdy base plate that can withstand rough handling. A base plate with a ruler or protractor can be useful for measuring angles or drawing maps.
Compass Calibration and Maintenance
To ensure accuracy, calibrate your compass before use by magnetically aligning the needle and checking the direction-of-travel arrow against a known reference point. This should be done at least once a week. Additionally, clean and dry your compass regularly to prevent damage from moisture or debris. Consider using a compass with a rotating bezel to make adjustments easier.
Additional Considerations
In addition to accuracy and durability, consider the environmental conditions in which your compass will be used. For example, a compass with a waterproof or water-resistant housing can withstand exposure to rain or immersion in water. A compass with a built-in clinometer or altimeter can also provide additional information about terrain and elevation.
