Sig Sauer introduced the BDX to a gathering crowd of gun owners at the NRA’s Annual Meeting in Dallas last week.
The BDX, or Ballistic Data Xchange, features wireless Bluetooth equipped rangefinders and riflescopes outfitted with integrated Applied Ballistics. In short, the BDX allows ballistic holdover information to be exchanged wirelessly between Sig Sauer BDX Electro-Optics products. Users simply download the BDX app — available on Android or iOS smartphones — pair the Kilo BDX rangefinder and Sierra3BDX riflescope and set up a ballistic profile. From there, shooters are ready to start pulling triggers.
In the field, users range the target as usual. The Kilo BDX rangefinder will use its onboard Applied Ballistics Ultralight to send the dope to the scope via Bluetooth. Using the ballistic profile, the ballistic solution is calculated for the target and will illuminate on the BDX-R1 Digital Ballistic Reticle displaying windage and elevation holds int he Sierra3DBX.
“Rangefinding riflescopes of the past have had two major shortcomings: they are either big, boxy and heavy, or extremely expensive,” Andy York, president of Sig Sauer Electro-Optics,
