For a versatile big game hunting scope, Bushnell's Trophy 3-9x 40mm Rifle Scope can't be beat. O-ring sealed and nitrogen purged, this powerful device is shockproof, fogproof and waterproof. Fully submerge it-still, no water will leak inside. Humidity and rapid temperature changes won't cause the lens to fog up. With this rifle scope, you'll get the best performance in any weather or lighting condition. The lens is fully multi-coated with an anti-reflective coating for higher-contrast, brighter images, which reduces eye fatigue. With six reticle options, you can adjust the scope to best suit your needs, while the side parallax and Fast-Focus eyepiece ensure you always get the most precise view of your target.
