Just getting back into mountaineering following a long lay off due to serious injury. In the meantime my trusty expedition 4 had gone astray.
Despite owning a collection of compasses, I bought a replacement of this one.
While all their needles point reliably north, this is my best one.
Distances are easier to measure courtesy of the romer scale for all map scales (including the increasingly popular 1 : 40,000 used by Harveys). It also has luminous markings, making it ideal for night navigation - you can see instantly when the 'red is in the shed'.
Its not the cheapest option but what's a few quid for an easier life?
