COMPASSES

BOS carries compasses from Suunto, Silva, and Moscow, from Boy Scout type to high-end competition compasses.

There are three basic types of orienteering compass: The first type, usually called a "baseplate" or "protractor" compass, has a (more or less) rectangular plate on which the the capsule containing the needle is mounted. The capsule has a ring, or bezel, around it with compass bearings etched into it. The capsule is rotatable, and using guidelines etched into the capsule and base, the user can set a bearing on the compass and easily follow it. The other type is called a "thumb" compass. It is attached to the thumb by an elastic band, and is held directly on the map at all times; its purpose is to keep the map oriented correctly to the terrain. A pure thumb compass has no provision for setting a bearing, but some models do have a rotatable bezel, either with or without the compass headings, and can have a bearing set on them - sort of "combo" models. The third type is a wrist compass, worn like a wristwatch; these are useful when your hands are otherwise occupied, such as in ski-O or mountain-bike-O

All the compasses with compass bearings have 2° gradations, except as noted

There are 2 different lines of compasses bearing the name "Silva". One is from Johnson Outdoors, a US company that makes basic compasses, and the other is from Silva AB, a Swedish company that makes competition compasses.

COMPETITION COMPASSES

MOSCOW COMPASS: Moscow compasses are unique in that the capsules and baseplates are all interchangeable. You can, for example get a baseplate model and an extra thumb plate, and switch the capsule back and forth to try out each style. When you order, you specify the capsule and plate, for example 11L, 2C, etc. Guaranteed for 3 years.
