Attention orienteers, especially those with smaller hands or who are left-handed!

This is the Silva Arc Jet C S compass, a compact version of the popular Arc Jet S model.

It's designed specifically as a 'thumb compass' for the sport of orienteering, where you need to navigate quickly with a map in one hand.

The 'C' stands for compact, meaning it has a smaller thumb plate (the part you put your thumb through) which is more comfortable for people with smaller hands.

The 'S' indicates it has the 'Spectra' speed dial system on the capsule.

The 'Left' means it's configured for left-handed use (the bearing numbers are oriented for easy reading when worn on your left thumb).

Despite the smaller plate, it has the same high-performance 'Silva Jet 2.0' needle and the same sized capsule as the full-size model, so you're not sacrificing accuracy.

The Spectra speed dial is a brilliant system that simplifies navigation at high speed – you basically memorize a number the needle points to and follow a sighting line, rather than meticulously aligning the needle with north every time.

It's a tool for serious orienteers who want to move fast and reduce mistakes.

You can also get an optional 'Arc Zoom C' magnifier that clips onto the baseplate for detailed map reading.

If you're into competitive orienteering and find standard thumb compasses a bit bulky, or if you're left-handed and have struggled to find a good compass, this Silva Arc Jet C S Left model is a precision instrument built for speed and comfort.

It's all about shaving seconds off your time in the forest.
