In this Sig Kilo 850 review, we find one of the most advanced rangefinders on the market with its super fast, digital signal processing software.  It has many of the great features of its big brother, and top hunting rangefinder, the Sig KILO 1250. The Kilo 1250 has a greater range and similar quality optics but has an improved optical light transmittance for low light conditions and image clarity.

It also incorporates sophisticated control logic, yet is easy to program and use. The Sig Killo850 is a real challenge to the big name competitor brands like Leupold, Nikon, and Bushnell. This device delivers a great deal of technology at a budget price at around $155.

Sig Saur now produces quality rangefinders, riflescopes, spotting scopes and also binoculars. The Sig KILO850 has 4x magnification with a 20mm objective lens. Also with Sigs special SpectraCoat™ anti-reflection coatings, this ensures superior (60%) light transmission and optical clarity.  The new Lightwave™ DSP (Digital Signal Processing) technology ranges a target at the fastest speed (0.25 secs) to the longest distance.

Also, in Scan mode, it allows continuously scanning of targets providing 4 range updates per second.  And the RangeLock feature displays the last range result when ranging distant targets. The Sig KILO850 also features line-of-sight (LOS) or angle modified range (AMR) measurement.  Range units can easily be set to yards or meters.

The rangefinder is also compact and lightweight with a polymer body. It also includes a diopter adjustment and a high transmittance LCD display. Also, the device offers user-selectable targeting modes featuring “LAST” or “BEST”. This helps the user to target with pinpoint accuracy.

OUR REVIEW VERDICT – Sig  KILO850

Like all Sig Sauer’s current rangefinders the Sig KILO850 comes with angle compensation, last and first target priority and a scan mode. Furthermore, these are the features most desired in a hunting rangefinder. Sig calls their angle compensation feature AMR (Angle Modified Range). The target priority mode options include either “Best” or “Last”. The Hyperscan mode is super fast, updating range four times a second. Much faster than the competition!

To protect against defects in materials and workmanship Sig Sauer offers a warranty that is second to none as rangefinder manufacturers go. They offer a full lifetime warranty on the optics and also a limited five-year warranty on the electronics.  

In this,  Sig KILO 850 rangefinder review we see Sig Sauer has produced a rangefinder of quality with many desirable features with the hunter in mind. You would expect this from a quality manufacturer like Sig Sauer. The LCD backdrop is non-illuminated, however, with black lettering only. This can be slightly difficult to see in low light conditions. But the quality Sig Kilo 850 rangefinder remains a good choice for the hunter at a bargain price.
