Protect your mirrored baseplate compass! This silicone base/case has been sold only with our TruArc20 for many years, and we decided to also make it available as a separate item to purchase. It also fits our TruArc 15/15-Glow and our GeoLite, but does not come with these models. It's a great way to protect the baseplate of any of our mirrored compasses since the lid already protects their tops. This helps avoid baseplate wear and tear while these compasses are in your backpack and can even be left on during use, prolonging the life of the baseplate markings. The case also forms a perfect place to store Quick Reference Card Sets, Grain Size Cards, Topo Buddy Cards, or anything that is thin and card-sized... Made in the USA. NOTE: The Silicone Compass Case comes with the TruArc 20 and 20-Glow models already. This case when sold separately comes with a cool TruArc sticker inside!
