Map tools, navigation tricks, and outdoor safety tips all in one.

As experts in the navigation field, Brunton created this lightweight and durable reference card set that can help you better explore, whether in the front country or backcountry.  

This set was created to be used with any map and compass and also stows neatly in the rubber foot of the TruArc 20 (not included). They contain essential references and tips and techniques for efficient and safe wilderness travel.  Our cards can help you calculate and determine distance, location, and slope on a variety of topo maps and will give you many of the basic tools and concepts that can help you make better decisions outdoors. Waterproof, durable, and lightweight cards can handle exposure to any type of weather.

Since 1894, Brunton has set the gold standard in precision equipment for field-based professionals and outdoor enthusiasts. This long heritage of innovation, reliability, and quality has a rich history deeply rooted in the Mountain West where the brand continues to thrive to this day.
