The Athlon Helos BTR Scope delivers a rare combination of rock-solid reliability, first focal plane reticle, premium optics, and-most notably-an affordable price tag. The aircraft-grade aluminum tube is argon purged and 100% waterproof, fogproof and shockproof, so you can hunt confidently anywhere, in any weather. The first focal plane reticle increases and decreases in size with magnification, so the holdover and ranging marks stay true at any zoom. The illuminated crosshairs and center circle provide another targeting option when your target is on the move at close and medium ranges. Advanced fully multi-coated optics and a unique XPL protective lens coating combine to provide exceptional clarity and color fidelity along with an added degree of durability for harsh environments. All these features would normally cost you quite a bit more, but the Helos BTR can be yours for a price that's easy to stomach.
