Silva Arc Jet OMC Compass

The Arc Jet OMC is the wrist compass in the Arc Jet-series. It has the Silva Jet 2.0 high performance needle with unmatched needle stability and the Spectra speed dial graphics on the capsule.

The OMC is attached to the wrist, which means you have both hands free while orienteering. Silva wrist compasses are appreciated by MTB orienteers and adventure racers around the world since it provides the same speed and performance as thumb compasses but enable navigation also while biking, kayaking, etcetera. Similar to a watch, the Arc Jet OMC can be used on either your left or your right wrist depending on your preference.

The wrist bands are easy to adjust and are rubberized at the inside for optimal friction – making sure the compass stays in place and fits comfortably on your hand.

Spectra speed dial
The Arc Jet OMC 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.
