The Sentinel has two scales - a horizontal scale to measure distance to the target, and a vertical one which facilitates adjustment when shooting at different distances. Initially the riflescope should be sighted at 50m. on the central cross hair. The distance is determined by putting a target with known width (0.5m) between the marks of the “>..<” type. If the target fits between the marks, you sho uld make the vertical adjustment according to the mark. So, you can make adjustments when shooting at distances of 15, 25, 50 and 100m. It is advisable to change the color of the reticle depending on the surrounding conditions. Red is best when used in clear viewing conditions, green is preferable for use when viewing is obscured. The color can be changed by a simple push of a button.
