Forget MOA, MIL, MRAD, first focal plane or second focal plane, perhaps even a DOPE log, at least for extended-range hunting situations. SIG Sauer’s Electro-Optics division has announced its Ballistic Data Xchange (BDX) optics line, which does all the work by using Bluetooth technology to send rangefinder data and other DOPE to the riflescope, allowing a shooter to instantly acquire his or her target. The new line was unveiled during the 2018 NRA Annual Meetings & Exhibits at Dallas.

The system works when a shooter loads his or her ballistic profile into the BDX app (free downloadable Applied Ballistics Ultralite calculator), then pairs it to a KILO BDX rangefinder (five models are available). Data is then transmitted directly to a BDX-1 reticle in one of the SIERRA3BDX riflescopes, which instantly creates a digital illuminated holdover dot for a hunter to take a shot. Incorporated into the app is something SIG calls “kinethic,” which notifies a hunter, based on his personal threshold data inputted, whether his shot is likely to meet that criteria.

But there’s more. American Rifleman’s Joe Kurtenbach chatted with SIG Electro-Optics President Andy York, and you can see their conversation here. To get the complete rundown on this new line, visit sigsauer.com.
