Serious shooters and bird watchers, this Burris 30x fixed power eyepiece takes your spotting scope to the next level! With a massive 64-degree apparent field of view, you get incredibly wide, detailed views that make target identification and ranging so much easier. The SCR Mil reticle is clean and uncluttered, with simple indicators that let you calculate hold-overs and estimate target size and distance without touching your turrets. The bayonet mount makes swapping between eyepieces quick and easy - no tools needed! With 18mm of eye relief and a twist-up rubber eyecup, it's comfortable for extended viewing sessions, even if you wear glasses. The high-density low dispersion glass and fully multi-coated optics deliver crisp, contrast-rich images with accurate color representation and minimal distortion. Argon gas purging and O-ring seals make this eyepiece completely waterproof and fog-proof, so weather conditions won't ruin your viewing. At 5 ounces and just 2.1 inches long, it's compact enough to carry in your pack without adding much weight. Perfect for long-range shooting, hunting, or any situation where you need precise magnification and ranging capabilities. The fixed 30x power might seem limiting compared to zoom eyepieces, but the optical quality and wide field of view more than make up for it. If you're tired of fuzzy edges and cramped viewing at high magnification, this Burris eyepiece delivers professional-grade performance that serious enthusiasts appreciate.
