Magnification: 20x, meaning objects appear 20 times closer than they would to the naked eye.Objective Lens Diameter: 50mm, which is a large lens that helps gather more light for brighter images, even in low-light conditions.Field of View (FOV): Indicated as 168m/1000m (or approximately 168ft at 1000yds), providing a specific width of view at a standard distance.Optics: Many models in this style feature multi-coated lenses (FMC) and BAK4 prisms to improve light transmittance and image clarity
