As with Mil-Dot spacing, the series of hash marks represent a unit of angle called an mrad (milliradian) or mil for short. This is equal to a gap of 3.6 inches at 100 yards, or 3 feet at 1,000 yards. This is equivalent to 10cm at 100m, or 1m at 1,000m.When magnification is set to 10× the TMX reticle allows for 16 mil spacing of hold-over to the outer edge of the field of view, along with 6 mil spacing of windage in each direction.When used at 20x magnification it allows for 8 mil spacing of hold-over to the outer edge of the field of view, along with 3 mil spacing of windage in each direction, the TMX is a versatile reticle that provides aim points no matter how extreme the conditions.
