Sig Sauer KILO 2000

Sig Sauer may have been around for a really long time, but their Electro-Optics Division that manufactures their optics hasn't. In fact, within the first year that they manufactured and released their optics products, they received not one but two distinguished top honors in the 2015 Field & Stream Best of the Best Awards. And, the Sig Sauer Kilo 2000 was the recipient of one of them!

The Kilo 2000 is a rangefinder that's been pimped-out with the company's latest generational technology to not only provide positive target acquisition in grueling conditions, but to do it accurately too. It has a staggering high-reflective target range of 3,400 yards! That's absolutely nuts, even for extreme long range hunters.

With such long yardage ranges available, you can bet that the unit has AMR (Angle Modified Range) for angle compensated distances to acquire the correct bullet holdovers for those long shots. When you can get a positive distance on deer at 1,200 yards away, you're going to need to all the distance info you can get.

With an OLED Lumatic Display that has automatic brightness settings to cater to ambient light conditions, you'll be set to acquire the distances you need no matter the time of day. Of course, the image quality is made even better with Sig Sauer's ultra-wide broadband, anti-reflection lens coatings. The SpectraCoat will ensure superior light transmission to ward off glare and ensure true color fidelity.

With a reputable brand behind the manufacturing, you can imagine that the Kilo 2000 is a very popular rangefinder indeed. It doesn't miss a beat when ranging, it's compact and lightweight, and the OLED display is an egg in your beer. With the price, you're definitely getting a whole ton of benefits for practically nothing. However, there have been some defective units that drain battery life quickly, shut down during cold (30 degrees Fahrenheit) weather, and inaccurate readings. Luckily, it doesn't seem to be the trend.

Sig Sauer Kilo 2000 7X25 Q&A:

What is the Actual Effective Yardage Range on the Kilo 2000?

Sig Sauer claims the highly reflective max range is 3,400 yards. Tree ranging is 1,500 yards, and deer ranging is 1,200 yards. Many buyers say its realistic range is between 900-1,000 yards for deer and 3,000 yards for highly reflective targets. However, you should note that ambient light conditions can also affect accuracy and rangefinder performance. Despite its limiting factors, the effectiveness of this rangefinder is incredible for the price range.

What is the Yardage Accuracy of the Claimed Yardage Ranges?

The Kilo 2000 rangefinder is accurate to within -/+0.5 yards up to 500 yards. From 500-1000 yards, you can expect accuracy to within -/+1 yard. From 1000 yards and beyond, accuracy is within -/+2 yards.

What is the Lumatic Display?

The AUTO setting is the most preferred setting as it adjusts brightness automatically for current ambient light conditions. In AUTO, the Lumatic Display is activated and uses the on-board ambient light sensor that's located in the objective of the rangefinder. It then calibrates the right brightness setting from 20 possible intensity options to suit your current conditions.

Can you Override the Lumatic Display?

You can manually adjust brightness settings for bright light, low light, and snow conditions. You have the option of toggling between LO1, LO2, LO3, MED1, MED2, MED3, HI1, HI2, HI3, or AUTO.

Will the OLED display be too Bright for Low Light Use?

No. The display will be set to the dimmest light possible to ensure eye protection during low light.

What are the Modes of Operation on Sig Sauer's Kilo 2000 rangefinder?

The Kilo 2000 has both Best and Last target modes with a HyperScan mode.

The Best target mode is the equivalent to First Target Mode, and Last target mode is the same as Second Target Mode.

HyperScan can acquire 4 updated readings in the span of a second.

How to Adjust the Focus?

Adjusting the focus for your unique vision prescription is easy with the diopter adjustment focus on the eyepiece. Rotate this eyepiece in either direction that allows up to a full 40 degree rotation until you have a sharp, clear image.

What is the Eye Relief on the Kilo 2000 Rangefinder?

The Sig Sauer Kilo rangefinder has eye relief of 15mm. It may be less forgiving for those who wear glasses. The eyepiece also has a twist-up eyecup that rotates clockwise 90 degrees to reduce eye relief by 6mm.

Noteworthy Features:

  • AMR technology for angle compensated distances
  • Extreme long ranging capability up to 3,400 yards
  • Best, Last, and HyperScan operation modes
  • Lumatic OLED Display for auto intensity brightness control
  • Sig Sauer Infinite Guarantee and Electronic Component Limited 5 Year Warranty

Our Verdict on the Kilo 2000 Range Finder

The aim of it is, the Sig Sauer Kilo 2000 rangefinder is in a class of its own. It's highly reliable, and its extreme long range performance changes the game for many hunters. However, proper inspection of your newly-purchased Kilo will ensure you can take advantage of the warranty in case you have a defective unit before hunting season begins and is over.

If you want to spend a little less, the impressive Sig Sauer Kilo 850 has equally stunning features. Still a long range unit with up to 1,200 yards and 600 yards on deer, you won't be left out of the loop on any distance you'll realistically need.

Still cheaper than the Sig rangefinder is the Leupold RX-1600i TBR with DNA. With up to 1,600 yards of ranging distance, 3 reticle options, and TBR technology with an OLED display, you will max out your potential as a master rifle hunter.

Sig Sauer has put themselves on the optics map since their release of the Kilo rangefinders in 2015. It's not hard to get on board when they literally offer it all for one, low price! Just put it to the test and you might be impressed.

Update: The Sig Sauer KILO2000 has been discontinued and replaced with the new line of BDX rangefinders. Check out the new Sig Sauer KILO2200 BDX at Amazon and Optics Planet.
