The Silvan Arc Jet series redefines your thinking about competition compasses. The compass features a new 2.0 needle that is more stable and reliable. The new Arc Wing design adds extra support and stability, and the compass has a detachable thumb plate that allows the user to choose whether they want their thumb to have direct contact with the map. The package includes two different thumb straps (soft and firm), as well as scale stickers that you can optionally stick to the board. The Arc Jet S model has a fixed needle case.

This model is suitable for both left and right-handed users. A magnifying glass is available as an accessory.
