The Cammenga Model 27 offers an economical alternative to tritium models while maintaining military-grade reliability. The phosphorescent markings charge quickly from any external light source (flashlight, sunlight, or ambient light) and glow in the dark for nighttime navigation. Unlike tritium, which requires no charging but is more expensive, the phosphorescent version gives you the same rugged construction and precision at a lower price point. You can identify it by the 'Phosphorescent' stamp on the back. It's ideal for budget-conscious preppers, scouts, and hikers who want authentic military specs without the premium cost.

The Cammenga Model 27 uses a copper induction dampening system that slows the compass needle's rotation electromagnetically—no liquids required. This is crucial because liquid-filled compasses can freeze in extreme cold, leak over time, or develop bubbles that affect accuracy. The liquidless design ensures reliable performance across a wide temperature range, from desert heat to arctic conditions. This makes it superior for tactical use, winter mountaineering, or any scenario where equipment failure isn't an option.

Absolutely. The Model 27 features dual-scale dial graduations in both degrees (0-360°) and mils (0-6400), making it versatile for civilian orienteering and military land navigation. The magnifying lens allows precise reading of the dial, while the sight wire enables accurate azimuth shooting to distant landmarks. Whether you're plotting a course on a USGS topo map or navigating a competitive orienteering event, the lensatic design and dual scales give you professional-grade accuracy. It's the same compass trusted by U.S. military personnel for decades.

Your Cammenga Model 27 comes complete with a protective carrying pouch, lanyard, and belt clip—everything you need for versatile transport. Attach the belt clip to your pack strap or tactical vest for quick access, use the lanyard to wear it around your neck during active navigation, or store it in the pouch to protect it from impacts when not in use. The waterproof aluminum housing withstands harsh field conditions, and at just 0.45 lbs, it won't weigh you down on long treks. Made in the USA with military-spec durability.

After a brief exposure to external light (30 seconds to a few minutes from a flashlight or sunlight), the phosphorescent markings on the Cammenga Model 27 will glow brightly for the first 30-60 minutes, then gradually dim over several hours. For best results during nighttime navigation, periodically recharge the markings with your headlamp or flashlight. This gives you enough luminosity to take accurate bearings in total darkness without draining batteries or relying on electronic devices—perfect for stealth operations, power-outage scenarios, or multi-day backcountry trips where you need a non-battery navigation backup.
