The Suunto A‑30 NH USGS Compass is a precision navigation tool engineered for reliable map work and outdoor travel in varied conditions. Measuring approximately 4.75 inches in length, the compass features a highly stable, polarity‑change‑resistant needle housed in a liquid‑filled capsule for smooth, accurate readings. A built‑in protractor with orienting lines supports precise map navigation, while the fixed declination correction scale allows for consistent adjustments without recalibration during use.

Additional functional elements include a magnifying lens for detailed map reading and luminescent markings for improved visibility in low‑light environments. Red metric scales enhance readability and accuracy when plotting routes. Lightweight at approximately 0.16 pounds, the compass is compact and easy to pack for hiking, orienteering, and field navigation. Manufactured in Finland, the A‑30 NH combines durable construction with practical features, delivering dependable performance for users who require accurate, non‑electronic navigation in outdoor settings.
