Silva Arc Jet Thumb Compass - High-Performance Orienteering

When you’re moving at full tilt through a technical trail or competing in a local orienteering meet, your compass should be an extension of your hand, not a distraction. Designed specifically for the left thumb—keeping your dominant right hand free for map work or clearing brush—the Silva Arc Jet is built for pure speed. Featuring the legendary Silva Jet 2.0 needle, it offers unmatched settling speed and stability, meaning the needle stays rock-solid even while you’re at a full run. The clean, fixed-capsule design and cut-out baseplate allow for direct thumb-to-map contact, giving you a tactile feel for your route. Whether you’re a seasoned pro or a first-time racer, this is the tool you need when every second counts.

• Left-Hand Orientation: Designed to be worn on the left thumb, allowing right-handed navigators to keep their dominant hand free for clearing terrain or using a magnifier.
• Silva Jet 2.0 Needle: Engineered for the perfect balance of speed and stability, providing world-class settling time so you can read your heading instantly while in motion.
• Arc Wing Design: The reworked baseplate provides extra support and stability for your thumb, ensuring the compass stays level and secure during high-intensity efforts.
• Direct Map Contact: A unique cut-out in the baseplate allows your thumb to touch the map directly, improving your tactile connection and map-reading accuracy.
• Customizable Grip: Includes an attachable thumb plate for a more traditional grip, plus both soft and firm rubberized thumb bands to ensure a perfect, non-slip fit.
• Adaptable Map Scales: Comes with four scale stickers (1:15k, 1:10k, 1:7.5k, 1:4k) that can be easily attached to the baseplate for quick distance measurements.
