A new feature of day rifle scope (DH 3-12x50 & DH 5-20x56)!
The scope has a built-in Electronic control of reticle level, enabling high accuracy shooting in a terrain with an obstructed horizon level (mountain hunting).
When the weapon slopes aside within 0 to 1 deg., the reticle will glint.
When the slope is more than 3 deg., the reticle will flash. To stop the flashering restore the horizontal position of the reticle.
When you angle of more than 1 degree, the reticle will blink red
