Sig Sauer BDX Technology Guide - OpticsPlanet.com
This video introduces the Sig Sauer BDX system, a digital ballistic solution that integrates a smartphone app with compatible optics and rangefinders. The BDX app allows users to create custom ballistic profiles for various firearms and ammunition. These profiles are then wirelessly transmitted via Bluetooth to Sig Sauer Sierra 3 rifle scopes, illuminating specific hold points on a digital focal plane reticle. The system can also integrate with Sig Sauer Kilo rangefinders for real-time ballistic data acquisition.
