SIG BDX

Sig Sauer Application Development

About this app

The KILO BDX rangefinders use Applied Ballistics and Bluetooth® to illuminate the exact holdover dot in SIERRA3BDX riflescopes.

For the most accurate and ethical shot, just Connect The Dot™.

- DOWNLOAD: Download the app

- SYNC: Sync the app with your rangefinder

- BOND: Use the app to bond the rangefinder with the riflescope

- RANGE: Press the RANGE button to measure the distance of your target

- POWER SELECTOR RING: When the SIERRA3BDX riflescope is actively paired with a KILO BDX rangefinder, the blue LED on the power selector ring will be illuminated solid blue. This Blue LED will flash quickly 8X for one second whenever the riflescope has received a new holdover reticle update from the rangefinder. The BDX system works out to 800 yards with 1 MOA of accuracy

- CONNECT THE DOT™: It’s time for hunting. Once the riflescope is turned on, range the target and the new hold is lit up out to 800 yards

Ratings and reviews

MISSING 2 CRITICAL FUNCTIONS: #1 No Import / Export function for Custom Profiles I have multiple custom profiles for a variety of loads for different platforms. I got a new phone and I have to enter each profile manually on the new device. This is is painful!! And shouldn't be necessary! App needs import/export function so I can simply export database file from my old device and import to my new device (without being required to create an account or use cloud services!!) #2 No Zero Offset It is not feasible to re-zero every time I switch rounds... I zero once with my most common load. App should use zero offset so calculator automatically compensates for how rifle is zeroed. All of my other ballistic calculators include this function. Why not BDX? If these two basic functions were added I would rate 5-stars. Everything else works great! Please add these CRITICAL functions ASAP!!!

NEEDS ZERO OFFSET SETTING! Like many shooters I have a target load and a hunting load. I know the zero and adjustments between each round, so when I'm getting data from my Kestrel (BDX-X mode) I can easily switch between the two rounds. When using the RF in BDX-U mode to come up with a quick dope, you either have to mechanically set your turrets to the different zero or remember to dial in the the difference every time you dope your turrets. Sig, It's a simple feature to add!

Needs im- and export. Who wants to reenter all that stuff again when getting a new phone or having to reset for whatever reason. Needs an offset for the ballistic engine. You are zeroing your rifle once for your most common load. You do not want to adjust the scope and use the turret for any different load all the time. Just shoot at same distance and enter the offset to the centre in the software. Works in any other ballistic solver, just not here: no offset. Other than that pretty cool.
