Durability and Environmental Resistance
A good field compass should be built to withstand the elements. Consider waterproof, shockproof, and sandproof construction, especially if you plan on using it in harsh conditions. Materials like rugged aluminum alloy or military-grade plastics offer superior longevity.
Illumination for Low Light
If you anticipate navigating in low-light or nighttime conditions, features like Tritium micro lights or fluorescent dial markings are essential. These allow you to take readings without relying on an external light source.
Additional Navigational Features
Depending on your activity, features like a clinometer for measuring slopes, UTM scales for map plotting, a magnifying glass for map details, or adjustable declination can significantly enhance your navigational capabilities.
Portability and Ease of Use
For most users, a compact and lightweight design is preferable. Features like a lanyard or a built-in carabiner can ensure quick access. Simplicity is key for recreational users, while advanced users might prefer more complex tools.
Who Should Buy What
For serious backcountry navigation and map work, the Suunto MC-2 NH or Eyeskey Multifunctional with its clinometer are top choices. If self-powered, long-lasting illumination is paramount, the Cammenga 3H Tritium is unmatched. Beginners and scouts will find the Suunto A-10 or Orienteering Compass Advanced simple and effective.
What To Avoid
Avoid compasses with sticky or slow-moving needles, or those that are not clearly marked for easy reading. Also, be mindful of compasses balanced only for a specific hemisphere if you travel widely. Cheap plastic construction might not hold up to rigorous use.
How These Products Compare
While all these compasses aim to guide you, they differ significantly in features and intended use. Military-grade options like the Cammenga offer extreme durability and unique illumination, while recreational models focus on simplicity and map-reading aids. Advanced tools like the Eyeskey add terrain measurement capabilities.
Understanding Declination Adjustments
When choosing a field compass, pay attention to its declination adjustment feature. This allows you to correct for the difference between magnetic north and true north, which is vital for accurate map work. Not all compasses offer this, so if you plan on serious backcountry navigation, look for models with adjustable declination.
Frequently Asked Questions
What is a lensatic compass and is it better for hiking?
A lensatic compass uses a sighting lens and a prism to provide very accurate bearing readings. While excellent for precision, they can be bulkier than simple baseplate compasses. For general hiking, a good baseplate compass is often sufficient, but a lensatic model offers enhanced accuracy for critical navigation.
How do I adjust the declination on my compass?
Declination adjustment allows you to correct for the difference between magnetic north and true north. Most compasses with this feature have a small screw or dial on the side or back. You’ll need to know your local magnetic declination (available from online sources or maps) and set the compass accordingly to ensure accurate readings relative to true north.
What does 'global balancing' mean for a compass?
Global balancing means the compass needle is designed to function accurately across different magnetic zones of the Earth. Standard compasses are often balanced for specific hemispheres (Northern or Southern). A globally balanced compass is ideal if you travel frequently or need a single compass for worldwide use.
Are Tritium compasses worth the extra cost?
Tritium compasses, like the Cammenga 3H, offer self-powered illumination that lasts for over a decade without batteries. If you frequently operate in complete darkness or prioritize ultimate reliability in remote, power-limited situations, the investment can be very worthwhile. For casual use, other luminous options may suffice.
