If you’re an avid hiker or Rambler its 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 pictured above 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 base plate.
