1. the Unit of Measure Method

<p> Judging Distance</p><p>Methods:</p><p>1. The Unit of Measure Method:</p><p>Take 100m, or any smaller recognised distance as your ‘Unit Of Measure’ and see how many ‘units’ you can fit between yourself and the target.</p><p>This method is no good unless you can see ALL the ground between yourself and the target is not effective over 400.</p><p>2. The Appearance Method:</p><p>The amount of detail visible of the human form at various ranges gives a good indication as to it’s distance from you.</p><p>At 100m - Clear in all detail.</p><p>At 200m - Clear in all detail but colour of skin and equipment only just identifiable. </p><p>At 300m - Clear body outline, face colour good, remaining detail blurred.</p><p>At 400m - Only Body outline clear, remaining detail blurred.</p><p>At 500m - Body begins to taper, head becomes indistinct.</p><p>At 600m - Body now wedge shaped, no head apparent.</p><p>Other factors:</p><p>Things seem closer than they are when :</p><p>-The light is bright or the sun is shining behind you.</p><p>-They are bigger than other things around them.</p><p>-There is dead ground between you and them. </p><p>-They are higher up than you.</p><p>Things seem further away than they are when :</p><p>- The light is bad or the sun is in your eyes.</p><p>- They are smaller than other things around them.</p><p>- You are looking across a valley, down a street or a ride in a wood.</p><p>- You are lying down. Aids to Judging Distance:</p><p>Halving: </p><p>Choose a point that you think is halfway to your target , estimate the distance to that point and double it.</p><p>Bracketing: </p><p>Say to yourself, "The target could not be more than x metres nor less than y metres away." Add x to y and halve the result, the answer is the estimated range. e.g. If x is 300 and y is 100, the range is 200m. </p><p>The further away the target is the wider should be the bracket that you use.</p><p>Key Ranges:</p><p>If you know the range to any point in your arcs you can estimate the distance to other objects from this.</p>
