UP with a direction arrow for elevation and L with a direction arrow for windage. This indicates the direction the shot will go, therefore if the shot is shooting right and you want the point of aim to go left you just turn the dial in the direction of the arrow. Same with the elevation, if its shooting low turning the turret with the arrow will raise the point of aim, agaist will lower it obviously.
I click will move the shot 1/4" at 100 yrds so at 25yrds you need 4 clicks for 1/4" inch shift. Its that simple!
