Abstract
In order to judge range with the laser range estimation aid the lasers (1, 2 and 3) should be activated via the switch (8) and directed at the target of range desired. The lasers (1, 2 and 3) should produce a triangle pattern of dots. If there is an upright triangle (10, 11), then the target is below or closer that the zero range. If there is a single dot, then target is substantially at the zero range (12). If there is an inverted triangle (13, 14), then the target is above or further away from the zero range. Also, the size of the pattern produced can be found relative to the terrain which allows for further range calculation.
