The Electro-Optics division of SIG SAUER announced their their all-new Ballistic Data Xchange (BDX) rangefinders and riflescopes with integrated Applied Ballistics® and wireless Bluetooth® technology.  This groundbreaking BDX technology enables interoperability and key ballistic holdover information to be exchanged wirelessly between SIG SAUER BDX Electro-Optics products.  The foundation of the BDX system was designed for simplicity and ease of use.  SIG SAUER BDX requires no new learning, and uses the same tools hunters and shooters have been using for years.

How does BDX work? It’s simple!

  • Pair the KILO BDX rangefinder and SIERRA3BDX riflescope
  • Set up a basic ballistic profile
  • You’re ready to shoot or hunt!

Once you are in the field, range your target as you normally would, and the KILO BDX rangefinder will utilize onboard Applied Ballistics Ultralight™ to instantly send your dope to the scope via Bluetooth.  Using your basic ballistic profile the ballistic solution is calculated for your target and will instantly illuminate on the BDX-R1 Digital Ballistic Reticle with windage and elevation holds in the SIERRA3BDX riflescope.  A blue LED on the riflescope power selector indicates that the BDX system is paired, and when the reticle has received new ballistic holdover and windage data from the rangefinder.

The BDX family of rangefinders includes: KILO1400BDX, KILO1800BDX, KILO2200BDX, KILO2400BDX, and KILO3000BDX rangefinder binocular.  These 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.

Available in 3.5-10x42mm, 4.5-14x44mm, 4.5-14x50mm, and 6.5-20x52mm, the SIERRA3BDX 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.

Rounding out these superior features is SIG SAUER’s kinetic energy transfer indicator: KinETHIC™. KinETHIC provides assistance in assuring an ethical hunt by indicating when energy on target drops below a threshold that can be set by the hunter using the BDX App.
