In May Sig Sauer Electro Optics released their highly anticipated 10x42 Kilo 3000 BDX range-finding binoculars. I managed to acquire a set for review and have been impressed from the outset with their unique features and low cost compared to others on the market.

 

The Kilo 3000 BDX are equipped with Applied Ballistics Lite software, and as the name suggests they will pair with your Sierra BDX rifle scope to provide a guaranteed 1 MOA accuracy holdover to 800 yards or 730 metres.

 

The design is a typical twin-barrel arrangement on a central hinge with the buttons (“range” closest to the eye and “mode” just beyond that) on the right side where your pointer and index finger rest. The focus knob is located above the ocular lenses for easy access with your pointing finger.

 

Constructed from a magnesium alloy, the Kilo 3000 BDX are approximately 15cm long, 12.5cm wide and weigh 879 grams including a battery which is par for a set of range-finding binos in today’s market. The binoculars are powered by a single CR123 battery which you will find under a slotted cap on the underside of the unit.

 

The alloy housing is coated in a firm, olive drab rubberised casing to protect the surface from knocks. It also helps the user maintain a good grip even with wet or bloody hands.

 

CLOCKWISE FROM LEFT: The two bulges house the laser and electronic software. Note the slotted battery housing cap; the focus ring is knurled to provide a secure grip and offers sufficient resistance to prevent it being turned accidentally; the “Mode” and “Range” buttons are handily located on the top of the binos within easy reach.

 

The underside of the Kilo 3000 BDX has two large bulges that house the range-finding electronics. These bulges fill the web of your thumb when you’re glassing and the fit does not feel intrusive, but rather natural as it fills the cup of your hands.

 

Each diopter has a rubberised adjustment ring and the eyecups are extendable with four settings to ensure correct eye-relief. My diopters were firm to adjust but not too loose. The focus adjustment knob is aggressively knurled for grip and stiff to adjust which prevents it moving as it goes back into your jacket pocket, or when you’re using the provided “bino bivvy” harness.

 

“The front of the central hinge contains a capped tripod adapter thread of 1/4x20 if you need extra stability for those extended glassing sessions.”

 

Sig Sauer provides a grey binocular harness similar in design to the popular hunting clothing brand Kuiu. This “bivvy” holds the binoculars close to your chest and keeps the rain and debris away from the eyecups. The harness allows you to distribute the weight of the binos evenly across your shoulders and connects via a set of small fastex clips.

 

The loops for the harness are flush-fitting in the frame for snag-free use. I thought the harness was a nice touch as most hunters I know with expensive binoculars keep them in something similar to protect them.

 

The rangefinder is very accurate and fast compared to its rivals. It is equipped with “Hyperscan” mode which gives you four readings every second for 20 seconds so the average read time is .25 seconds. The laser beam divergence is 1.5x0.6 Mrad (15cm at 1000m) making it very narrow and accurate for ranging distant objects.

The front of the central hinge contains a capped tripod adapter thread of 1/4x20 if you need extra stability for those extended glassing sessions.

 

The display inside the binoculars is a red/orange OLED that automatically adjusts its brightness compared to the object you are glassing. This can be changed to any one of ten settings if you find it too bright or not bright enough. The ranging reticle is a circle which makes accurate ranging simple and easy. The display appears only in the right barrel and can be focused with the right-hand diopter.

 

The Kilo 3000 BDXs are equipped with Bluetooth and as mentioned, Applied Ballistics Lite software which provides a ballistic solution to a maximum distance of 800 yards/730 metres. The software draws the environmental data from the internet via your phone, or it can be inputted by the user via the SIG BDX application on your phone.

 

This app controls the data and gun profiles you can load, and will also let the binos know whether you are working in MOA/Mrad or metres/yards.

 

The Kilo 3000 BDX can store a single rifle profile but the application in your phone can store over 200. Changing is as easy as syncing your smart device with your Kilo 3000 BDX. If you have a Sierra BDX riflescope you can bond the binoculars to this scope and it will provide illuminated hold-over points for elevation and illuminated deflection points for wind.

 

MODES

The mode button can be held down for three seconds to cycle through yards/metres AB modes, brightness settings, and best or last laser readings. The AB modes include AMR, LOS, ABU and ABX. AMR is “Angle Modified Range” which calculates the equivalent horizontal range to your target including angle, commonly used with bows or BDC turrets.

 

LOS is the direct Line of Sight” range without modification, plus you will have the inclination displayed as well. ABU is Applied Ballistics Lite” which uses the profile loaded via Bluetooth to provide an elevation and windage hold-over. This displays for two seconds after first displaying the range based on the loaded rifle profile from your app.

 

ABX is “Applied Ballistics External”, a feature that allows you to pair the binoculars with an external Bluetooth device such as the Garmin Foretrex 701 or Kestrel Elite 5700. Both these devices are equipped with Applied Ballistics Elite which will compute the solution based on the atmospheric data they are reading, the range from the binoculars, and the rifle profile loaded into them.

 

They will then send the elevation and windage hold back to the binoculars which will display them for two seconds, then cycle through range, elevation and, windage for ten seconds. This effectively gives you ballistic solutions to as far away as the Kilo 3000 BDX will range!

 

The ABX (“Applied Ballistics External”) feature allows you to pair the binoculars with an external Bluetooth device such as the Garmin Foretrex 701 or Kestrel Elite 5700.

 

I tested this feature at the Sparrowhawk Individual Long Rifle Challenge and was able to range and get solutions as far out as 4009m. We ranged the 1600m target and engaged it with my .338 Lapua Magnum resulting in three out of five hits, proving that this system is the go-to for long range shooting and extreme long range (ELR) competition.

To make sure the Kilo 3000 BDX’s systems were accurate we measured the laser readings with a surveyor’s laser and found that the binos were within .8m at 1700m which is under 0.05%!

 

Frazer tested the bino’s ABU mode using his .264 Win Mag profile. This set-up allowed him to score repeated hits out to 800 yards with 1MOA accuracy.

 

To test the ABU mode I took my .264 Win Mag up to the range where I have steel targets all the way out to 800 yards and engaged them in a series randomly, using the rifle’s profile loaded into the binos.

 

With my handloaded 143 grain ELD-X smoking at 3250fps I managed to hit all 12 targets all the way out to the maximum distance of 800 yards. All the impacts were bang-on for elevation and with the exception of my poor wind calls they hadn’t strayed within the 1 MOA guarantee.

 

“We ranged the 1600m target and engaged it with the .338 Lapua Magnum resulting in three out of five hits, proving that this system is the go-to for long range shooting and extreme long range (ELR) competition.”

 

Overall I am very impressed with the Kilo 3000 BDX. The ED glass is as good as the Sig Sauer Zulu 5 binoculars (or better) and the rangefinder is extremely fast and accurate. When coupled with the BDX functionality it makes them very hard to beat. If you are a hunter, an ELR shooter or getting into PRS style matches I wouldn’t recommend any other glass or rangefinder.

 

They are competitively priced at $2399 and a Kestrel 5700 Elite will set you back $1275, making the combo cheaper than a set of range-finding binoculars from the nearest competitor. You get the benefit of a “weather station” and still have some cash in your pocket.

 

Warm barrels and stay safe out there!
