Arc JET SpectraThis Silva compass is an optimal thumb compass for orienteers.
The Arc-series is built on the Silva Jet 2.0 needle. The needle has been designed to provide great balance between speed and stability.
The thumb baseplate is designed with a cut-out to provide contact between thumb and map, and an attachable thumb plate for those who prefer the more classic thumb grip. Simply slide it on/off to the baseplate with a simple click, try it out and see what you like the best.
Furthermore, the thumb bands are easy to adjust and come in two versions, a soft and a firm band. They are both included in the package and are rubberized at the inside for optimal friction – making sure the compass stays in place and fits comfortably on your hand.
