The HELIX is designed in a way that puts the important things first: clear glass, smart reticles, innovative features and a turret system superior to other products in the same price class. The HDLR takes things one step further, with ED Glass, Reticle Illumination, a massive Zoom Range and more Elevation Travel. Tthe ever popular Tool-Free system and Zero-Stop on the Elevation turret have been kept for ease of use when dealing for extended ranges, but the windage is capped for a more hunterfriendly,compact feel. Stringent quality control procedures give you peace of mindwhen taking that 1000 yard shot and if something goes wrong, the Platinum Lifetime Warranty has you covered!
