The BDX family of rangefinders includes: KILO1000BDX, 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.

Meet the SIERRA3BDX 2.5-8x32mm. This non-traditional riflescope still carries the trusted features of a traditional rifles scope such as; the look, feel, weight, and size. It also features HD glass for superior resolution and optical clarity, 30mm main tube, side-focus parallax adjustment, 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.

How does BDX work?

The BDX rangefinder and riflescope system is simple, fast, and intuitive.  Simply download the “SIG BDX” app available for Android or iOS smartphones, pair the KILO BDX rangefinder and SIERRA3BDX riflescope, set up a basic ballistic profile, and then 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 D.O.P.E. (Data on Previous Engagement) 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.   

SCOPE  FEATURES AND SPECS

• Integrated BDX™ Ballistic Data Xchange. A rangefinder and riflescope system that uses ballistics, environmental conditions and Bluetooth® to illuminate the exact holdover dot.
• Automatic holdover dot on a Digital Focal Plane™, combining Second Focal Plane stadias, with an OLED illuminated ballistic holdover dot that automatically scales with zoom to subtend on target at any magnification level.
• The updated SIG BDX App now include profiles for crossbow ballistics, through entering bolt weight and speed.
• Features MOTAC™(Motion Activated Illumination) that powers up when it senses motion and powers down when it does not. Provides for optimum operational safety and enhanced battery life
• SpectraCoat™ highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission
• SIG SAUER’s innovative KinETHIC kinetic energy transfer indicator. 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 SIG BDX App.
• New for BDX riflescopes, Auto LevelPlex, automatically increases digital level sensitivity on longer shots
• Dependable waterproof (IPX-7 rated for complete immersion up to 1 meter) and fog-proof performance
• The SIERRA3BDX is covered by SIG SAUER’s INFINITE Guarantee™ and Electronics Limited Warranty, see website for full details 
• SIG BDX APP Now includes the ability to create multiple profiles for both firearms and crossbow ballistics.
