When used together KILO BDX rangefinders and SIERRA BDX riflescopes combine to create the most advanced optics system available on the market today. Simply configure your ballistics profile in the BDX app, pair your KILO BDX rangefinder with the app, and then bond it to your SIERRA BDX riflescope. When you range your target the KILO BDX rangefinder automatically sends your specific holdover data to your SIERRA BDX riflescope giving you an illuminated holdover dot. It’s simple and fast.

BDX 2.0™ allows users to quickly and easily bond their laser rangefinders to their BDX sights using the QUICKbond™ feature. 8 preloaded ballistic groups are already loaded on the rangefinder for the user to be able to use the product right out of the box.

BDX combo kits now come pre-bonded from the factory. Combining this with the new ballistic groups preloaded on the KILO rangefinders allows users to quickly and easily begin using their BDX products.
