Yeah, I saw that. A lot of practical shooting info. I like the range finder, and the objects appear closer/farther guidelines Penetrating 33.5" of pine seems a bit optimistic but I'm not volunteering to stand on the other side

What the hell is a 'milliradian'?

On the very top of the chart, there is a milliradian ruler. Each small increment is equal to 2 Mils. In the handbook, Oparin gives an example of using the ruler. For example, if you need to measure the distance to the turn of the road, you’ll need to place the ruler at 50 centimeters from your eye (average distance of outstretched hand) and measure by how many Mils the road is covered at that distance. Let’s say the road’s width at the needed distance measures 14 Mils. Knowing that the width of that road is 7 meters, you can place those numbers into the following formula and get the distance to the turn of the road.Distance = Heigh(Width) x 1000 / MilsIn our example, the distance to the turn of the 7 meter wide road that covers 14 mils will be 500 meters (7 x 1000 / 14 = 500).It’s important to know that the Soviet Mils are slightly different than NATO Mils. Both are rounded for the sake of calculations simplification. Milliradian (or Mil or Mrad) is an angular measurement that is equal to one-thousandth of a radian (one radian is about 57.3 degrees). The NATO Mil is slightly smaller than the true milliradian. It measures 0.982 of the real Mil. The Warsaw Pact/Soviet Mil is a bit more than the real milliradian and measures about 1.047 of real Mil.
