Riflescope · digital reticle
4.5-14x44 riflescope with 30 mm main tube and a digital BDX-R1 reticle that shows an illuminated holdover dot with BDX rangefinders.

This version has the digital BDX-R1 reticle in the second focal plane and the model is finished in black.
A rangefinder and riflescope system uses ballistics, environmental conditions and Bluetooth to illuminate the exact holdover dot.
The manufacturer combines second focal plane stadia with an OLED illuminated holdover dot that scales automatically with zoom.
The motion activated illumination powers up when it senses motion and powers down when it does not, which helps battery life.
The indicator shows when energy on target drops below a threshold that can be set in the SIG BDX app.
The digital anti-cant system automatically increases its sensitivity on longer shots according to the manufacturer.
Broadband anti-reflection coatings reduce surface reflections across the visible spectrum.
Pairing with rangefinder and smartphone runs over Bluetooth and the SIG BDX app; an indicator LED on the riflescope shows the Bluetooth connection.
According to the manufacturer the riflescope is waterproof up to 1 metre (IPX7) and fog proof.
Reticle design

The drawing shows a crosshair with thick outer posts and a fine centre; the reticle stadia sit in the second focal plane.
An orange glowing dot marks the holdover below the centre; with a BDX rangefinder the system sets it automatically.
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.
According to the manufacturer the holdover dot scales automatically with magnification and works on the second focal plane stadia.
Rings or mounts for a 30 mm main tube are required; height and rail system are selected separately. A mount is not included.
* Firearms, mounts and other accessories shown are not included unless they are expressly listed. The selected product variant and the described scope of delivery are decisive.
