To sharp-shooter, the distance that judges a target is the most important, measure the interval of the target only allowed, ability computation plays path data, amend height to compensate zephyr to slant with this. The reason is bullet gives chamber hind, ceaseless straining can fall in gravitational influence, height of long as it happens compensates zephyr to slant, can let bullet be hit along a perfect arc far be apart from a target.

So, estimation is apart from the basic skill that is sharp-shooter, how Where is estimation? Use the scale in snipe lens and number.
The scale inside snipe lens is mil dot perhaps calls mil graduation, its usage is sharp-shooter first make choice of one foregone (probably) of height consult content, say an automobile for example, a person waits, consult this next content is covered into scale inside, look consult content held scale of how many case, cover reading into formula again, be like (target height × 1000) distance of ＝ of reading of ／ mil dot, can calculate give a space. Manage together, the mil that according to consulting content width holds on transverse scale, also can calculate the space that gives a cause.
Additional, the PSO-1 that resembles gun of Russia SVD snipe lays mirror, those who use is law of another kind of simple and easy range finding. Should aim at lens to press 1.7 meters on scale (one the individual's height) consult content height computation became good distance, consult this the content mil distance on different distance is in with curve scale demarcate aim at lens to go up. When using, what the body card that wants a standing position end only is laying lens wrong lower part is horizontal with the curve between, corresponding reading × is the target distance to sharp-shooter 100 meters.

After measuring an interval, sharp-shooter can pass the handwheel of on any account on snipe lens, go up to corresponding scale according to distance adjustment, can undertake aiming at with the accurate heart that lays mirror, shot. Aim at the scale of shape of a few arrowhead in lens as to PSO-1, be to be used at be apart from fire to undertake assisting aiming at to aiming at lens adjustment more than, the largest correction space that PSO-1 lays mirror is 1000 meters, if the target exceeded this distance, undertake aiming at with these a few arrowhead. For instance the target is 1100 meters, use the 2nd arrowhead most advanced undertake aiming at, the target is 1300 meters, use most below of an arrowhead most advanced undertake aiming at.
