Design and Build Quality
Cammenga Tritium Compass 3H
The Cammenga 3H is built like a tank, with a powder-coated aluminum frame designed to withstand the harshest conditions. Its lensatic design is straightforward, prioritizing functionality over flash. Weighing more than the Suunto (exact weight not specified in the provided data), it feels solid and rugged, ideal for military and survival applications. The compass is available in Olive Drab, blending seamlessly into tactical or outdoor settings.
Suunto MC-2 G Mirror Compass
The Suunto MC-2 is lighter at 75g (2.65 oz) and more compact, measuring 65 x 101 x 18 mm. Its plastic bezel and baseplate design prioritize portability without sacrificing durability. The mirror compass design includes a sighting mechanism, making it ideal for precise bearings in mountainous or complex terrains. The sleek, modern aesthetic appeals to outdoor enthusiasts who value both form and function.
Winner: Cammenga for rugged, heavy-duty build; Suunto for lightweight portability.
Key Features
Cammenga Tritium Compass 3H
- Tritium Illumination: Equipped with 7 Tritium micro-lights that provide continuous, self-powered illumination for over 12 years—no batteries or recharging needed. Perfect for low-light or nighttime navigation.
- Non-Liquid Filled Needle: Uses a copper induction-damping ring for quick, stable needle settling without the risk of liquid leaks, ensuring reliability in extreme temperatures (-50°F to 150°F).
- Accuracy: Offers precision within ±40 mils, suitable for military-grade navigation.
- Accessories: Includes a pouch, lanyard, instruction booklet, and clam-shell case for easy carry and protection.
Suunto MC-2 G Mirror Compass
- Globally Balanced Needle: Features a jewel-bearing needle balanced for global use, eliminating the need for separate northern/southern hemisphere models. The needle has a 20-degree tilt margin for easier readings in varied magnetic zones.
- Mirror and Sighting Features: The mirror, sighting hole, and notch allow for precise bearings, while a magnifying lens aids in map reading. A clinometer measures slopes, ideal for mountaineers assessing avalanche risks.
- Low-Light Usability: Luminescent markings enhance visibility in dim conditions, though they rely on ambient light exposure for glow, unlike Cammenga’s self-powered Tritium.
- Additional Tools: Includes metric UTM scales, an inch ruler, and a detachable snap-lock lanyard with a wristlock for secure carrying. A declination correction tool is also provided.
- Accessories: Comes with a lanyard, declination correction tool, and quick guide.
Winner: Suunto for its versatile feature set, including the clinometer and global needle balance, ideal for diverse outdoor activities. Cammenga excels in self-powered illumination and simplicity.
Durability and Environmental Performance
Cammenga Tritium Compass 3H
The Cammenga is designed for extreme conditions:
- Shockproof and damage-resistant for rough handling.
- Waterproof to considerable depths and sandproof for desert environments.
- Temperature Range: Performs flawlessly from -50°F to 150°F, unaffected by temperature changes due to its non-liquid filled design.
This compass is battle-tested, making it a go-to for survivalists and military personnel who need a tool that won’t fail in harsh environments.
Suunto MC-2 G Mirror Compass
While the Suunto is also built for tough conditions, its plastic construction may not match the Cammenga’s rugged aluminum frame. However, it’s still highly durable:
- Liquid-filled capsule ensures stable needle operation but may be less reliable in extreme cold compared to Cammenga’s non-liquid design.
- Designed for Challenging Terrains: The clinometer and sighting features make it ideal for mountainous environments, though no specific temperature range or waterproof rating is provided in the data.
Winner: Cammenga for superior durability and extreme condition performance.
Usability
Cammenga Tritium Compass 3H
The lensatic design of the Cammenga is intuitive for those familiar with military-style navigation. Its Tritium illumination ensures readability in complete darkness, a critical feature for night operations. However, it lacks advanced features like a clinometer or magnifying lens, which may limit its versatility for complex navigation tasks like mountaineering.
Suunto MC-2 G Mirror Compass
The Suunto’s mirror compass design is more versatile for technical navigation. The sighting mirror, clinometer, and magnifying lens make it ideal for precise bearings and map work, especially in mountainous or forested areas. The globally balanced needle eliminates the need to choose a hemisphere-specific model, making it more user-friendly for global travelers. However, its luminescent markings require prior light exposure, which could be a drawback in prolonged darkness compared to Cammenga’s Tritium.
Winner: Suunto for technical navigation and versatility; Cammenga for simplicity and low-light reliability.
Price and Value
- Cammenga Tritium Compass 3H: At $109.20, it’s pricier but offers military-grade durability and self-powered illumination, making it a worthwhile investment for those prioritizing reliability in extreme conditions.
- Suunto MC-2 G Mirror Compass: At $92.00, it’s more affordable and packed with features like the clinometer and global needle balance, offering excellent value for mountaineers and frequent hikers.
Winner: Suunto for better value due to its lower price and broader feature set, though Cammenga justifies its cost for specialized users needing extreme durability.

- You’re a military professional, survivalist, or outdoor enthusiast needing a battle-tested, ultra-durable compass.
- You prioritize self-powered illumination for nighttime or low-light navigation.

Final Verdict
Both the Cammenga Tritium Compass 3H and Suunto MC-2 G Mirror Compass are exceptional tools, but they cater to different needs. The Cammenga is the go-to for those who demand military-grade durability and reliability in extreme conditions, with its self-powered Tritium illumination being a standout feature. The Suunto, however, offers a more versatile and feature-rich experience for mountaineers and technical navigators, with its clinometer, global needle balance, and sighting capabilities—all at a lower price point.
Ultimately, your choice depends on your specific needs: Cammenga for rugged simplicity and reliability, or Suunto for precision and versatility. Whichever you choose, both compasses are built to guide you through the wild with confidence.
