Spectra speed dial

The Arc Jet S has an updated, more clean version of the original Silva Spectra System and it is developed to simplify your orienteering. The Spectra speed dial consists of reference markings and numbers on the capsule. You just need to memorize the number that the needle is pointing at after completing step 2 of the Silva 1-2-3 system and the sighting line will guide you in the right direction as long as the needle stays pointing at that number. Designed like a clock, the speed dial is easy to read and memorize and enables you to move faster and more accurately while orienteering. No matter if you are an elite or leisure orienteer, the Spectra speed dial will help you stay on the right course at high speed while reducing mistakes.
