Silva Thumbcompass ARC Jet S
A new compass with a super stable needle and a very fast settling speed, which was developed in collaboration with Tove Alexanderson and the Swedish national team. The compass case is stiff and cannot be moved. This new can from Silva is made in such a way that it should no longer draw air bubbles. This compass is produced in such a way that you can orientate yourself on the gray-white shades and the numbers from 1 to 12. This is the successor to the legendary Spectra system (orientation by color). But with the new system based on numbers and gray and white levels, it should be even easier than before. Because before that, the colors on the compass always interfered with orientation and confusions and errors occurred during orientation. With this new system, that should no longer happen. In addition, the compass is equipped with the new thumb plate that can be used open or closed. This makes the compass a compass for everyone.
After the first tests, the compass is faster and better than the Str8. The specialty of this new compass is that the thumb plate can be changed from open to closed thumb plate. In addition, the ARC JET S is more manageable and clearer than the previous thumb plates from Silva. The compass is very handy, lies well and comfortably on the thumb and is very clear, so that only a fraction is covered by the map.
Arc Jet S is your compass if you are looking for a powerful thumb compass with the well-known Spectra graduation on the compass socket. The Spectra pattern consists of reference marks and numbers to make orienteering easier. This compass has all the high-end features you need for fast navigation while running, and is available in left and right versions, depending on your needs.
The Arc series is based on the Silva Jet 2.0 needle and a revised design of the compass box. The new needle is designed to ensure the perfect balance between speed and stability. It has been tested by elite orienteers throughout the development process. The combination of the new compass socket and the Jet 2.0 needle offers you a compass with first-class performance in terms of speed and settling time, transparency and unmatched needle stability.
Customize your Arc Jet S.
The thumb base has a unique design with a cutout that provides perfect thumb-to-card contact and a clip-on thumb plate for those who prefer the more classic thumb grip. Slide the thumb plate onto the base plate with a simple click, try out which way of carrying you like best. In addition, the thumb straps are easy to adjust and come in two versions, a soft and a tight strap. They are both included in the scope of delivery and are rubberized on the inside to ensure an optimal fit. So the compass holds reliably and lies comfortably in your hand.
If you want to use map rulers to easily measure distances on the orienteering map, simply stick one of the supplied scale stickers to the base plate. The Arc Jet compass comes with four different scales; 1: 15k, 1: 10k, 1: 7.5k or 1: 4k.
Spectra navigation ring
The Arc Jet S has a modern, updated version of the well-known Silva Spectra system and was developed to make orienteering easier. The Spectra division consists of reference marks and numbers on the compass box. All you have to do is remember the number that the needle points to after completing Step 2 of the Silva 1-2-3 system. The line of sight will guide you in the right direction as long as the needle is pointing at that number.
The Spectra graduation is designed like a clock, easy to read and easy to remember, and it allows you to move faster and more precisely during orienteering. Regardless of whether you are an elite or recreational orienteer, the Spectra division helps you stay on the right course at high speed and reduce errors.
When every second counts
Combine the Arc Jet Compass with the Arc Zoom Magnifier as an optional accessory. The zoom magnifying glass can easily be attached to the base plate of your thumb compass and helps you read the map faster and more precisely - perfect when every second counts. Due to the functional design, the zoom magnifier is well integrated into the compass.
