The Mildot Master® is an analog calculator designed along the principle of a slide rule, utilizing logarithmic and inverse logarithmic scales developed specifically for performing the following operations:

  • Rapid and simple calculation of range to target, based on a measurement of the target with a mildot reticle, by aligning the estimated target size directly opposite the mildot measurement, and then reading the range at an index mark. 

  • Rapid and simple calculation of the amount of sight correction necessary to compensate for bullet drop and/or wind drift for a given range, enabling the shooter to determine either the equivalent telescopic sight adjustment (minute-of-angle, or MOA) or the equivalent hold-over (mils), by reading equivalents in both MOA and mils directly opposite the bullet drop/wind drift figure.

  • Additionally, angle of fire for uphill or downhill shots can be accurately measured, and the up/down compensation can be closely calculated to reduce the errors such shots can induce.

 

The mil-dot reticle is in increasingly widespread use among long-range rifle shooters as a means of estimating the range to the target. This estimation is critical in order to correct for the varying degree of projectile drop (and/or wind drift) at different ranges and thereby enable the shooter to hit the target. With training and familiarization, an experienced marksman can accurately estimate range to target by using this type of reticle and by making the appropriate calculations. Originally fitted to telescopic sights designed for military (and later police) use, the mil-dot reticle has seen growing acceptance in the civilian sector among target shooters and hunters. 

By using a set of fixed references within the scope, the shooter can compare the size of the target, a portion of the target, or a nearby reference target to a series of precisely sized dots and spacing. By estimating the size of the target or nearby reference and noting the number of mils that equal the size of the target, the shooter can determine the range to the target by applying a formula (size of target in yards multiplied by 1000, divided by size of target in mils, equals range to target in yards), usually done with the help of a conventional hand held electronic calculator.

 

However, there are problems associated with the use of an electronic calculator. The Mildot Master® is designed to eliminate these problems.
