BDX PACK: KILO1800 BDX + SIERRA3 BDX 4,5-14x50 scope


Distance measurement and spot retention at all distances

The BDX optics package represents a revolutionary combination of rifle scope and rangefinder. The biggest advantage is an automatically corrected stop for shooting at any distance in any terrain. No estimating distances and holding over, but measuring distances, aiming and hitting spots. The corrected stopping point moves on the reticle, taking into account shooting range, atmospheric influences, shooting angles and the ballistics of all common calibres and loadings at the touch of a button.

How does BDX work?

The BDX rangefinder and rifle scope system is simple, fast and intuitive.  Simply download the "SIG BDX" app for Android or iOS smartphones, connect the KILO BDX rangefinder and the SIERRA3 BDX rifle scope, create a basic ballistic profile and off you go.  Once in the field, you reach your destination as usual, and the KILO BDX rangefinder uses the built-in Applied Ballistics Ultralight to instantly send your dope to the scope via Bluetooth.  Based on your basic ballistic profile, the ballistic solution for your target is calculated and immediately illuminates on the BDX-R1 Digital Ballistic Reticle with windage and elevation handles in the SIERRA3BDX scope.  A blue LED on the scope power selector indicates that the BDX system is paired and when the reticle has received new ballistic data from the rangefinder.

That's how it works:

1. download app
Install the app for IOS or Android and select load. Send information to the KILO 1800 BDX Rangefinder.

2. products connect
The App Ballistic Data Xchange connects the KILO 1800 BDX Rangefinder with the SIERRA3 BDX scope via Bluetooth.

3. successful hunting
The BDX Rangefinder measures and communicates the distance to the BDX scope. The reticle immediately indicates the new stop to be able to hold stain.
