Silva Arc Jet Spectra

Arc Jet S is a high-performance thumb compass with a clearer, low-obstruction capsule and the Spectra speed-dial graphics that make fast, accurate navigation feel intuitive. Choose left or right-hand configuration to match your grip. 

At its core is the Silva Jet 2.0 needle inside a redesigned capsule - engineered for rapid settling and rock-steady tracking at race pace, and proven by elite orienteers during development. The result is quick readings, excellent stability, and superb map visibility when you're moving hard. 

Make it yours: the thumb baseplate includes a cut-out for direct thumb-to-map contact plus a clip-on thumb plate if you prefer a classic grip. Two adjustable thumb bands (soft and firm) are included, each with an inner rubberised surface for secure, comfortable fit. Add the stick-on map scales to the baseplate for easy distance measuring: 1:15k, 1:10k, or 1:4k.

Spectra speed dial simplifies the Silva 1-2-3 method - memorise the number the needle indicates after step 2, then keep the needle on that number and go. The clock-like markings are easy to read at a glance, helping you stay precise at high speed.

Want even more detail at pace? Pair Arc Jet S with the Arc Zoom magnifier (optional), which snaps neatly onto the baseplate for faster, clearer map reading when every second counts.
