If you're an avid hiker or rambler, it's all very well having a GPS or a smartphone, but you should always have an "old-fashioned" map and compass to fall back on. Alternatively, sometimes I find half the fun of a walk is following your route on a map — getting slightly lost is part of the fun.
The Silva Expedition 4 Compass is the civilian version of the compass that is developed by Silva for use by the British Army. Traditionally it is used in the infantry as a soldier's or officer's compass. The compass has a full-sized baseplate.
