A reticle is a pattern of lines or markings in the eyepiece of a scope or sight, used to help aim accurately at a target. It is commonly found in devices like riflescopes, telescopes, and binoculars. The reticle provides a reference point for shooters and observers, allowing them to align their sight with the target effectively. Reticles come in various designs, such as crosshairs, dots, or more complex patterns, depending on the intended use. Some modern reticles even include illuminated features for better visibility in low-light conditions. Overall, a reticle enhances precision in aiming and targeting.
