Over the years I have tested and used countless rangefinders from Leica, Bushnell, Nikon, Vortex and others. Back in 2003, I wrote Rangefinder Roundup, in which I evaluated five models: the Leica LRF 900 Scan, Nikon Laser800, Nikon Laser400, Bushnell Yardage Pro 500 and the Bushnell Yardage Pro Scout. Today, I consider all of these models essentially obsolete, except for the Leica, which is still a good line of sight rangefinder today.

In 2009, I tested the then new Leupold RX-1000 Laser Rangefinder. It instantly became my favorite rangefinder and has been on every hunt with me since. Back then, I mentioned that it takes a lot of combinatorial features to make a good rangefinder, even more to make a truly outstanding one. At the time, it was the best rangefinder I had ever evaluated in terms of practical, real-world field use. The RX-1000 soared to the top based on size, ease of use, an outstanding LED display and outstandingly good image quality.

There are a couple of things about the new Sig KILO2200MR that make it a standout. The OLED display self-adjusts to ambient light, which is a huge leap forward from rangefinders you have to adjust manually.

As much as I have used my Leupold, after sunset the red display can blow you out of the reticle. Using the Sig Kilo2200MR along side of my Leupold, the Sig's red OLED display was just about perfect: crisp, visible and it self-adjusted instantly without me having to do anything. Half an hour after sunset is just about the worst possible time for me to be fiddling with anything and the Sig removes this hassle.

The Sig KILO2200MR is a relatively upscale rangefinder, selling at $399 from B&H Photo as I write these words. The Leica 7x24 Rangemaster CRF 1600-R sells for $599 from B&H. I mention it here, as the Leica is the most similar model on the market to this Sig.

I generally take manufacturer's stated ranging abilities with a grain of salt, for ambient conditions and, in particular, the amount of dust and particulate matter in the air can change things dramatically. I ranged a windmill at a repeatable 1966 yards with the Sig, even though I am not going to be hunting windmills anytime soon.

The accuracy of the Sig Kilo2200MR is stated as within two yards at 1000 yards, which is better than most. It is also extremely fast, 0.25 second to range an object. It ranged as close as 5.6 yards, which is better short range capability than most rangefinders on the market.

I like the design of the Kilo2200. It has a nice gripping texture on the top and bottom of the unit. The 7x power monocular is more appropriate than the more common 6x for longer ranging and the ranging circle is a bit smaller than on other units, including the KILO2000 this unit replaces.

With a built-in inclinometer, you have Line of Sight and "shoot as if" modes. Sig refers to their incline-compensated mode as AMR, or Angle Modified Range. Aside from the basic, uncluttered circle, OLED reticle that I prefer, you can switch to your choice of two milling reticles, one that is horizontal and one that has both horizontal and vertical milling lines.

I am confused by the Sig Warranty. Sig states this rangefinder comes with the, "INFINITE GUARANTEE. Sig Sauer Electro-Optics are guaranteed forever." Except, not really, for Sig proclaims on the same page:

"5 YEAR WARRANTY (Electronic Component Limited 5 Year Warranty). Covers any defects in materials and workmanship in the electronic and Tritium components of illuminated riflescopes/sights, pistol sights, electronic sights, flashlights, lasers, binoculars, spotting scopes and rangefinders for five years from date of manufacture."

If the electronic component of a rangefinder doesn't work, you do not have a rangefinder. This tells me that the actual warranty is up to, "five years from date of manufacture." I have no idea when the tested unit was made and there is no way to tell from the serial number. This leaves me not knowing what the warranty is. As it is a new model, I would guess that I have four years or so left from when it was made.

This confusing lifetime / five years from date of manufacture stuff gives me a slight headache. It is probably twice as long as the two years you get from Leupold or Leica, but it is not nearly as good as the true lifetime warranty you get from Vortex. I would be far happier if Sig lost the double talk and just gave a five year warranty from date of purchase.

The Sig Kilo2200MR does not have a built-in tripod adapter, something that I feel it should have. You can use a tripod, but you have to buy a $99.99 tripod adapter sleeve to do so. It would be far better if a standard tripod mount was integral to the housing. The lack of a tripod mount and the strange non-lifetime warranty are my only two niggles with this rangefinder.

Overall, the Sig Kilo2200MR is the best rangefinder I have reviewed to date, based on its blazing fast ranging performance, ease of use, comfortable to hold textured housing and the ambient light compensating OLED reticle. It is the only rangefinder most hunters will ever need.
