Whether you're teaching orienteering skills deep in the wilderness or your own backyard, the Silva Education Kit provides everything needed, besides an appropriate topographic map, for a single instructor and 24 students to navigate solely with a compass and map. This portable compass clinic comes in a rugged carrying case for safe transport. Silva Polaris compasses, compass instructions, and Read This, or Get Lost brochures are provided for 24 pupils. Each Polaris compass features a rotating bezel for locking in your bearing, with a declination scale for adjusting between magnetic and true geodetic north. There's also inch and millimeter rulers, with a scale that corresponds to common 1:24,000 topographic maps. The instructor receives a Silva Explorer compass that's similar to the Polaris compass, except it features a built in magnifier for reading map details, as well as a 110 mile scale for both 1:24,000 and 1:62,500 topographic maps. As with the Polaris compass, there's an inch ruler. An attached lanyard makes for easy carrying around your neck. Moreover, the instructor receives a Teaching Orienteering guide, as well as a Be Expert with Map Compass paperback.
