The BDX family of rangefinders include many of the legacy features that the KILO name was built on: Lightwave DSP digital rangefinder engine, Hyperscan with 4 times per second scan rate, RangeLock, and the Lumatic auto-adjusting display. The SIERRA3 BDX riflescopes have the look, feel, weight, and size of traditional riflescopes. They feature HD glass for superior resolution and optical clarity, 30mm main tubes, side-focus parallax adjustments, and the LevelPlex digital anti-cant system. The BDX-R1 Digital Ballistic Reticle is the evolution of holdover, providing a ballistic solution out to 800 yards with 1 MOA of accuracy.
