Hunt and eliminate pests just about any time of the day or night, regardless of the lighting conditions, if you have this scope. If your target animal has a light brown coat, you can use a reticle color that contrasts sharply with it, giving you greater odds of a one-shot kill. Same goes with shooting animals that would ordinarily make the traditional black reticle useless. Just turn on the reticle, and you're good to go.
