SIG SAUER's all-new Ballistic Data Xchange (BDX) rangefinders and riflescopes are equipped with integrated Applied Ballistics and wireless Bluetooth technology. This groundbreaking BDX technology enables interoperability and key ballistic holdover information to be exchanged wirelessly between SIG SAUER BDX Electro-Optics products.

The BDX family of rangefinders includes: KILO1400BDX, KILO1800BDX, KILO2200BDX, KILO2400BDX, and KILO3000BDX rangefinder binocular. Available in 3.5-10x42mm, 4.5-14x44mm, 4.5-14x50mm, and 6.5-20x52mm, the SIERRA3BDX riflescopes have the look, feel, weight, and size of traditional riflescopes. Rounding out these superior features is SIG SAUER's kinetic energy transfer indicator KinETHIC. It provides assistance in assuring an ethical hunt by indicated when energy on target drops below a threshold that can be set by the hunter using the BDX app.

"Over the past few years, I have put SIG riflescopes on all of my rifles and have had great results. When Sig Optics rolled out the new BDX system this year, I knew one of my guns would be getting the scope switched out with the Sierra3 4.5-14x44 BDX that pairs with the KILOBDX rangefinder.

The Bluetooth setup for this is pretty easy and straightforward. Once you download the SIG app on your phone, you input your load data and sync it to the rangefinder. The rangefinder then talks to the scope and illuminates a dot on where you need to hold out to 800 yards. It works super quick and is deadly accurate. I first tested it at the range from 100 to 500 yards with flawless results and impacted the target on every shot. I felt confident with the results and was ready for my Montana antelope hunt.

The results on the hunt were just as I had experienced at the range. The buck I harvested was moving quite a bit, and adjusting a turret would have been a little difficult. The KILO1800BDX gives very quick readouts and made it very easy to make a one-shot kill on him. The BDX system would be a great scope option for anyone." - Isaiah Joner, Outfitter Specialist and Professional Hunt Advisor
