The Silva® Polaris® Base Plate compass is an instrument for the advanced orienteer as well as novices to map-and-compass work.

  • Clear base plate with inch, millimeter and 1:24,000 scales, makes it easy to read a map, set bearings, and plan a trip
  • Features 2° graduation lines with large numerals at every 20° for easy reading of bearings
  • Red and black orientation lines facilitate establishing your position on, or setting your course from, a map; scales help determine distances
  • Large sighting arrow helps you set your course across the land; large bezel and ergonomic design make it easy to hold and use
  • Fixed declination scale accomodates quick adjustments of map bearings to field headings
  • Base plate lanyard hole lets you keep the compass handy around your neck (lanyard not included)
  • Friction-free sapphire bearing allows the tungsten steel needle to swing freely; permanently clear fluid keeps it steady
  • Instructions explain how to find yourself on a map given known landmarks and how to set a bearing across the land using a map

Imported.
