Featuring Sig Sauer’s BDX technology, the KILO3000 BDX is the world’s most advanced laser rangefinder. When paired with a SIERRA3BDX riflescope, the onboard Applied Ballistics Ultralite calculator sends ballistic drop data via Bluetooth directly to the SIERRA3BDX’s BDX-R1 reticle, providing an illuminated holdover dot and wind hold. Download the free BDX App for iOS or Android to setup ballistic profiles and synchronize custom profiles to your KILO for exact ballistic solutions.

Sig Sauer BDX is the newest in electro-optics technology. BDX or Ballistic Data Xchange technology is found in the new Sierra3BDX and Sierra6BDX riflescopes and KiloBDX rangefinders. To get the most out of your BDX products you can also download the SIG SAUER BDX app on Android and Apple devices and receive information via Bluetooth. The BDX allows for both accuracy and simplicity.

About Sig Sauer

From humble beginnings as a wagon to factory to one of the world’s largest firearms, optics, and ammunition manufacturers; the history of Sig Sauer is rich in innovation and achievement. After winning a contract from the Swiss government in 1864 for their Prelz-Burnand muzzleloading rifles, the Swiss Wagon Factory change its name to Schweizerische Industrie-Gesellschaf, the Swiss Industrial Company, better known as SIG. In 1949 SIG developed the SIG P49, the predecessor to the P210 and continued developing small arms for the Swiss military and police.

Since then the company has changed its name, acquired other firearm manufacturers, and crossed the Atlantic—setting up headquarters in New Hampshire. However, what hasn’t changed is the innovative spirit that has driven SIG SAUER to develop firearms like the SIG516 rifle, MCX rifle, P320 pistol, and P226 pistol. With clients like the Texas Rangers, United States Secret Service, Navy Seals, and dozens of local law enforcement agencies nationwide; SIG SAUER is there When It Counts.

Crushes my old 1mile LRF, 1000 yards in direct sunlight with no tripod in about half a second. Really impressed. Glass beats the vortex LRF binos and connects drictly to my kerstrel. Can't beat it.

Kilo3000BDX is a serious rangefinder. Just out of the box, I ranged a building at 4068 yards. I use for shooting steel and it has no problem with what I have tried (up to 1 mile). Haven't used it for hunting or tried with animals. ABU mode gives you mil adjustments on the screen up to 800 yards. ABX mode connects with Kestrel for use beyond 800 yards. The bluetooth connectivity was a little sketchy for me with limited range (< 5 feet) so I have sent it back to manufacturer to test/repair/replace. Optics are great and I love the 10x on a rangefinder.

I have ranged deer out to 1500 yards, trees out 4200 yards. So sweet. The ballistics are accurate out to 800 yards. I am extremely happy with these.

Hands down the best binocs I have ever used. I used them both on my deer and elk hunt in NV. The light that gets through at sunrise is amazing. The range finder with my Sierra BDX scope was a plus on my deer hunt. One shot and dropped where he stood. I have recommended the BDX to all of my friends.

Love these. They worked perfect. The Bluetooth hooked up great to the phone and easy to navigate. Rugged and feel good in hand. Glass is awesome. Only stretched it out to 1300 yds so far but confident it will get out as far as I will ever need. Well worth the investment for quality range finder.

Excellent range finder. Easy to use. Ranged out to 3200 yards on a barn easily. Ranged pine trees out to 2000 plus and a hillside 3600. I was limited on the distance I could test these, I have seen my friends range farther. These are excellent binos too. I recommend these.

Easy to use. I synced with my phone and the Sig BDX app and was up and running within minutes. Entered ammo specs in the phone app, synced with Bino's, and they display exact drop at range. Will be purchasing the Kestrel 5700 (Maybe the newer 5700X) next for full Applied Ballistics software support.
