Daytime illumination of the rifle scope reticle serves a different purpose than twilight illumination, and in such rifle scopes, high intensity levels are a necessity. The illumination of the reticle is meant for rapid target acquisition, since a bright red dot is the best possible aiming point. Shooters’ eyes are instinctively drawn to a bright red dot in the center of the field of view. Such strong illumination is feasible only in rifle scopes with magnification lower than 1.5x or ideally 1.0x. Such wide-angle rifle scopes with a real 1.0x magnification and daytime bright illumination of the reticle can even be used with both eyes open, similar to reflex/red dot sights.
Rifle scopes with daytime illumination are the best choice for IPSC, CQB, tactical shooting and driven hunting in bright daylight.
