The Zeiss VariPoint VM/V Rifle Scope features an illuminated, red dot reticle that is housed in the second focal plane for a consistent size throughout the power range. Reticles #54 and #56 feature bars in the first plane that magnify with the image. This aids in estimating the distance to the target based on the thickness of the bars and the distance between them. Illumination is controlled by a flat rotary switch and automatically adjusts for intensity based on the surrounding light. Waterproof, fogproof and shockproof, this Zeiss scope includes plastic lens covers and is coverd by the Zeiss limited lifetime warranty. CR2032 3V lithium battery powered.
