New Sig Sauer BDX

DocUSMCRetired · May 4, 2018

NEWINGTON, N.H., (May 4, 2018) – The SIG SAUER Electro-Optics division today unveiled their all new Ballistic Data Xchange (BDX) rangefinders and riflescopes 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 foundation of the BDX system was designed for simplicity and ease of use. SIG SAUER BDX requires no new learning, and uses the same tools hunters and shooters have been using for years.

How does BDX work? The BDX rangefinder and riflescope system is simple, fast, and intuitive. Simply download the “SIG BDX” app available for Android or iOS smartphones, pair the KILO BDX rangefinder and SIERRA3BDX riflescope, set up a basic ballistic profile, and then you’re ready to shoot or hunt. Once you are in the field, range your target as you normally would, and the KILO BDX rangefinder will utilize onboard Applied Ballistics Ultralight™ to instantly send your dope to the scope via Bluetooth. Using your basic ballistic profile the ballistic solution is calculated for your target and will instantly illuminate on the BDX-R1 Digital Ballistic Reticle with windage and elevation holds in the SIERRA3BDX riflescope. A blue LED on the riflescope power selector indicates that the BDX system is paired, and when the reticle has received new ballistic holdover and windage data from the rangefinder.

“Rangefinding riflescopes of the past have had two major shortcomings: they are either big, boxy and heavy, or extremely expensive,” said Andy York, president, SIG SAUER Electro-Optics. “The revolutionary and affordable BDX system packs advanced ballistics technology into a simple platform that looks just like the rangefinder and riflescope that every hunter is using today. It is extremely simple to use; range a target, put the digital ballistic holdover dot on target, pull the trigger, impact. Incredibly accurate and extremely simple, just connect the dot.”

The BDX family of rangefinders includes: KILO1400BDX, KILO1800BDX, KILO2200BDX, KILO2400BDX, and KILO3000BDX rangefinder binocular. These rangefinders include many of the legacy features that the KILO name was built on: Lightwave DSP™ digital rangefinder engine, Hyperscan™ with 4 times per second scan rate, RangeLock™, and the Lumatic™ auto-adjusting display.

KILO BDX Rangefinders starting at $299.99 MSRP
SIERRA3BDX Riflescopes starting at $599.99 MSRP

Available at dealers July, 2018.

Very cool....looking forward to seeing how this technology evolves.

Will a Sig Kilo 2400ABS work with this system?

The short answer is that it is complicated. To get that answer you should go here: 603.610.3000, option 1

I am liking these new BDX Rangefinders but having trouble finding comparison details between a few. So between the Kilo 2200mr and the 2400abx is the ballistics software. But since these BDX rangefinders all do the same thing (from what I understand), what’s the difference between the 2200BDX and the 2400BDX, other than $300? They both advertise the same range, and the same software, any insight or clarification?

Hardware differences. One has different hardware which gives it better ranging capability, including a better lens for the sensors.

Awesome thanks for the reply.

Got to play with this system about a month ago. Pretty cool technology.

Is there any advantage to buying a 2400abs rather than the 2400 bdx if I already own a kestrel 5700 elite?
Thanks in advance

The meat and potatoes difference is this........the 2400 ABS has the built in sensors as listed below...........

• Embedded Applied Ballistics Elite with bullet database and support for G1/G7 and AB Custom Drag curves. Users can choose CDM or G1/G7 when profile building.
• AB Ballistics Engine: Most accurate ballistic solver on the market. Trusted by professionals.
• Aerodynamic Jump, Spin Drift, & Coriolis Effect are all calculated in the system (Embedded sensors adjust for this in real time).
• Temperature, pressure and humidity sensors for real-time environmental inputs to the embedded ballistic calculator and the ability to train for muzzle velocity shift with temperature shift.

The 2400BDX does not have the above mentioned sensors and has the AB Lite ballistic solver built in which limits you to only 800yds and no custom drag curves (when not used with a Kestrel Elite), BUT the one trick the 2400BDX can do that the 2400ABS can't (as of now) is communicate with a Kestrel Elite another words it can automatically send the range to a Kestrel and then the Kestrel can/will calculate the firing solution.

If I already had a Kestrel Elite and didn't already have a LRF I would probably go with the 2400BDX and use it with the Kestrel now if Sig updates the firmware on the 2400ABS and lets it also communicate with a Kestrel I would maybe go that route.

Is it possible for you to elaborate on this complicated answer? I’m sure the sensors cost some money in the 2400 ABS (over the BDX) but I think there is enough left over to warrant pushing some firmware to the 2400 ABS users. It’d be nice to populate target cards on the Garmin and/or Kestrel....Particularly for field matches.

Thanks.

Firmware updates on the device are currently not that easy to perform.

Just picked up a 2200bdx at a decent price for dad he wanted a range finder and we love our kilo 2200 thus far. Couple of questions i can't seem to find the answer to. So the BDX range finders all have AB lite, which will display elevation holds in the range finder and on the app, using the app to gather environmentals via weather apps/resources, for 800yds. Am i reading that correctly? That's kind of what i'm going for something he can point, range, see his elevation and dial.

On the other hand for myself, the 2400ABS sounds more my speed simple so i don't have to carry the kestrel with me, mainly because my 4000nv is lacking in all the advancements that have been made. Having said that, does the 2200bdx have the external link to a kestrel 5700? To the point i could use them to the effect of the 2400abs for hunting?

Also can an apple watch run the BDX app? That would be seriously beneficial to avoid having to pull out the phone. I suppose that the Garmin is meant for that but idk apple watch with the capability of the app seems more applicable rather than having to input everything.

Based on the sig manual, yes
https://www.sigsauer.com/wp-content/uploads/2018/09/18SIG_KILO2200BDX_Manual-7401006-01R00.pdf

Line of sight range, elevation and wind hold information is calculated instantly and displayed based on the active profile.

I can't find the reference right now, but my research says that it does not. From what I had read, you needed the 2400BDX to pair with Kestrel or Garmin.

Seems interesting idea but not supported at present.

One thing I noticed with the 2400 ABS is the temperature reading from the unit is very much affected by your body temperature when holding the unit without gloves, it doesn't take long for your body temp to increase the temp from the actual outside temp. You can override the temp from the unit and input the actual temp from a Kestrel which is way more accurate.

Individual1 · Apr 24, 2019

From what I've read; the AB Lite isn't limited to 800. Just no Drop Scale Factor (DSF) capabilities in the subsonic zone and uses G1/G7 solver.

Steel+Killer · Apr 24, 2019

Just to give an example of the data AB Lite request vs the data Regular AB request it's like this......

AB Lite
Bullet Data
1. Bullet Diameter
2. Bullet Weight
3. Ballistic Coeff

Firearm
1. Muzzle Velocity
2. Zero Range
------------------------------------------------------
Regular AB
Bullet Data
1. Bullet Diameter
2. Bullet Weight
3. Ballistic Coeff
4. Bullet Length

Firearm
1. Muzzle Velocity
2. Zero Range
3. Sight Height
4. Zero Height
5. Zero Offset
6. Twist Rate

I thought there was something wrong with the BDX app when I didn't see it ask for the sight height, but then I guess only calculates from your zero and beyond so from the rifle to your zero point it doesn't need to know that......am I thinking about that correctly?

Definitely my observation as well. Particularly if it’s in a pocket or bino pack snug to your chest.
