Features in practical use
BDX Ballistic Data Xchange
A rangefinder and riflescope system uses ballistics, environmental conditions and Bluetooth to illuminate the exact holdover dot.
Digital Focal Plane
The manufacturer combines second focal plane stadia with an OLED illuminated holdover dot that scales automatically with zoom; there are 10 daylight settings.
MOTAC
The motion activated illumination powers up when it senses motion and powers down when it does not, which helps battery life.
KinETHIC energy indicator
The indicator shows when energy on target drops below a threshold that can be set in the SIG BDX app.
LevelPlex with Auto LevelPlex
The digital anti-cant system automatically increases its sensitivity on longer shots according to the manufacturer.
SpectraCoat lenses
Broadband anti-reflection coatings reduce surface reflections across the visible spectrum.
Adjustment and parallax
Elevation and windage offer 40 MOA total each with 20 MOA per rotation; parallax is adjustable from 50 yards and the diopter range is ± 2.
Waterproof to IPX7
According to the manufacturer the riflescope is waterproof up to 1 metre (IPX7) and fog proof; the purge gas is nitrogen.
Reticle design
BDX-R1 Digital
Illuminated holdover dot
An orange glowing dot marks the holdover below the centre; with a BDX rangefinder the system sets it automatically.
Wind holds beside the centre
To the left and right of the centre the drawing shows two more orange dots: the manual (SIERRA3BDX, R04, section "Wind Holds") describes wind holds, which are only available when paired to a BDX rangefinder. They correspond to the wind value selected on the rangefinder; the symmetrical setting gives both left and right wind holds, the directional setting only one value for the selected wind direction.
Scaling with magnification
According to the manufacturer the holdover dot scales automatically with magnification and works on the second focal plane stadia.
