Silva Expedition 4 Compass

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.

I found the below video on You Tube, it is a great video taking you through the functions and uses of a compass (despite fuzzy background noise)
