Iím a bit uneasy about some of the comments on accuracy of compasses in this thread. My perception is that, for a plain scale, accuracy is a function of the size of the scale irrespective of units; a 3Ē (75 mm) protractor is going to be less accurate than a 6Ē (150 mm) one. With compasses there are additional factors such as declination and local magnetic variation. Any time Iíve used a pocket compass to take bearings to establish my position there has always been an error of around a couple of degrees, itís why 3 bearings taken from a fixed point never cross at a point. Itís not a problem so long as the error is recognised and taken into account, such as aiming off the feature youíre travelling to. Military types need mils scales for their own purposes (mind you, the though of using a pocket compass for gun laying really does scare me!) but civilians use civilian maps and they are marked in degrees - it makes very good sense for a civi to use a compass calibrated in degrees. To do otherwise increases your workload, probably fine in good conditions when youíre not tired, but not ideal at the end of the day when it's starting to rain.
Just my thoughts on the matter.
Wall, what wall?
