SIG Sauer is well-known for its top-notch firearms. What you may not know is that the SIG Sauer KILO2000 rangefinder is also at the head of its class in the optical world.

SIG Sauer makes 5 rangefinders in the KILO line with the most popular being the KILO2000, so I’ll concentrate on that model in this KILO review.

If you want to check the pricing and availability of three of the models at Amazon, click one of the links below. (As of this writing, the KILO2200 and KILO2400 were not available at Amazon.)

What Makes the KILO2000 So Popular?

The KILO2000 is a 7×25 millimeter rangefinder. It magnifies your target to 7 times its actual size. The 25 millimeter objective lens is almost as large as that on some compact binoculars. It does a great job of collecting light so you can find your target.

The main features contributing to its popularity are its ranging capability, speed, and cost.

The model name of the KILO2000 suggests that it can range bright targets as far away as 2000 yards. Most manufacturers will make such claims for their rangefinders under perfect conditions. In real world use, owners rarely see such promises hold true.

Owners of the KILO2000, however, find that they can consistently spot targets 2200, 2700, and even 2900 yards accurately to within 0.1 of a yard. This is obviously well beyond a mile (1760 yards) and even more than a mile and a half!

You’ll be happy to know that homing in on these distant objects doesn’t take you all day either. In just seconds (perhaps a few more for those farthest targets) your KILO2000 tells you how far away that deer or person or tree is.

SIG Sauer designs this rangefinder, not only for military and law enforcement users, but also for hunters, archers, and competitive shooters. You won’t need to give up an arm and a leg to get one for yourself. The cost of the KILO2000 is in the same range as many low to mid-range optics, but it gives the same performance as those priced many hundreds, if not thousands, of dollars more.

See the KILO2000 in action in this video from Sportsmans Warehouse.

What Technology Gives the KILO2000 Its Capabilities?

Lightwave™ DSP and HyperScan

DSP stands for Digital Signal Processing. SIG Sauer’s version lets you range faster at longer distances and more accurately than the majority of rangefinders on the market.

When you turn on scan mode, your KILO2000 uses HyperScan to refresh the range a speedy 4 times per second so it can keep up with your movement. It does so even when ranging distances over a mile.

Lightwave is programmed using the most up-to-date Field Programmable Gate Array (FPGA). What all that technical jargon means to you is that you will get fewer false positive signals and will still be able to find those weak and/or distant objects.

Lumatic OLED Display™

This technology includes an ambient light sensor “which continuously monitors light conditions and adjusts the display brightness accordingly”.


AMR means Angle Modified Range. This is Sig Sauer’s acronym for true shooting range calculation. You’ll find other manufacturers use other terms for the same feature.

You get a built-in inclinometer that reads the angle or incline or decline and changes the ballistic shooting range to your target for you. You can use it in combination with SIG Sauer Ballistic Turret Dials.


Electro-optics design means that the surface of your device is broken up into trapezoidal shapes to help prevent it being spotted when in use. Obviously this is more meaningful to military and tactical personnel.

Related to this feature are the pistol slide serrations and the grip checkering that you get with your rangefinder.


The lenses of your KILO2000 are coated to “reduce surface reflections to extremely low levels across the entire visible spectrum”. This allows more light into the system that gives you a clearer, better picture and lets the rangefinder do its job better too.

Other features of interest to most users are the twist-up eyecup that you can set according to the strength of your eye and the fact that the KILO rangefinder is both “waterproof” and fogproof.

I put “waterproof” in quotation marks because, although SIG Sauer uses this term, it also states that the KILO is “IPX4”. This means that it is only “water resistant”. You can splash water on the rangefinder from any direction, and it should be fine. (You need a rating of at least IPX7 before you should feel safe dropping it in a few feet of water.)

What Is the Warranty on the SIG Sauer KILO?

You get both a warranty and a guarantee with your rangefinder.

The warranty lasts 5 years. According to SIG Sauer, it “covers any defects in materials and workmanship in the electronic and Tritium components of…rangefinders for five years from date of manufacture.” (It also covers their other products besides rangefinders.)

Their Infinite Guarantee means the electro-optics are guaranteed forever. This is an unlimited lifetime guarantee. Exactly how that differs from the warranty, I can’t say.

How Does the KILO2000 Differ from the Other Models?

Very briefly, the KILO850 is a 4×20 millimeter rangefinder. The KILO1250 is a 6×20 millimeter rangefinder. Both have most of the features of the KILO2000, but you can’t expect them to range as far.

Probably the other main feature you could be concerned about is the display. Instead of an OLED display, you get an LCD readout.

You can see how the SIG Sauer performs compared directly to two competitors in the video below.
