Possibly the best rangefinder on the market! From Sig Sauer's Optics department comes the Kilo 2000. Extreme accuracy is what we were after when we engineered the KILO2000. Updating at 4X per second in HyperScan mode, the KILO2000 rangefinder with patented LightWave™ DSP technology is amazingly fast as well. Couple that with the ability to range reflective targets at 3400 yards, trees at 1500 yards, and deer at 1200 yards for simple, intuitive long distance ranging. The built in inclinometer calculates AMR™ Angle Modified Range for angled shots. Our proprietary Lumatic OLED Display™, automatically adjusts display intensity to match ambient light conditions, bright in bright conditions and dim in twilight to protect your eye. The KILO2000’s simplified user interface displays your system status and while ranging, only provides your necessary data. 

Stealth ID:
Electro-Optics industrial design inspired by our legendary firearms; deflection armor trapezoidal surfacing breaks up the shape and visibility of the optic along with pistol slide serrations and grip checkering to add function to the form of all SIG SAUER electro-optics.

SpectraCoat:
Highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission.

AMR:
Ranging technology uses an on-board inclinometer that reads incline/decline angle and modifies the effective ballistic shooting range to the target. AMR is the equivalent horizontal range and integrates perfectly when used in combination with SIG Ballistic Turret Dials.

LightWave DSP:
Lightwave DSP (Digital Signal Processing) engine leverages HyperScan– an advanced power management technique that provides the fastest refresh rate in scan mode (4 times per second) even at distances over a mile. Our DSP engine uses the latest generation Field Programmable Gate Array (FPGA) running sophisticated signal processing algorithms to reduce false positives while finding weak or distant targets.

Lumatic:
The most advanced display on the market. Our OLED (Organic Light Emitting Diode) display has the largest dynamic range providing for high brightness in bright sunlight or snow conditions, yet will dim down to near nightvision levels at dusk and dawn. No other display offers this adaptive ability to prevent your pupil from constricting in low-light causing you to no longer be able to see your target.

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.

Infinite Guarantee:
SIG SAUER Electro-Optics are guaranteed forever. It's an unlimited lifetime guarantee;
-Unlimited Lifetime Guarantee
-Fully Transferable
-No Warranty Card Required
-No Receipt Required
-No Time Limit Applies
-No Charge

I managed to get my hands on one of these today for a quick test and I have to say I am suitably impressed. Extremely sharp / clear optics and very fast ranging. If you want the best you need to take a look at the Kilo2000 from Sig Sauer.
