SIG Sauer has made the laser rangefinder smaller than it has ever been. The KILO MICRO 4x18mm monocular weighs just 3.4 ounces (96 g) and measures 2.7 by 1.2 by 1.9 inches. "Built to go anywhere" is the slogan, and whatever fits my pocket is always welcome on the tour. The KILO MICRO uses GEN II Lightwave DSP, which delivers fast, accurate ranging with extreme short-range resolution. It reaches reflective targets out to 1,000 yards, trees out to 800 yards and deer out to 600 yards. The laser divergence is 2.6 by 1.2 MRAD.
Two modes cover the main use cases. Eight onboard firearm ballistic groups give shooters and hunters the data for confident shots at changing distances, and a dedicated Archery Mode serves bow users. Angled Modified Range (AMR) uses an onboard inclinometer to compensate for uphill and downhill angles, so the displayed range is the equivalent horizontal distance.
The 4x18mm monocular has a 9.6 degree field of view, a minimum of 18.5 mm of eye relief and a plus or minus 3 diopter adjustment. The red and green Lumatic adaptive TOLED display automatically adjusts to changing light, and the reticle is a circle. SpectraCoat anti-reflection coatings maximize light transmission, while LensArmor coatings protect the lenses from abrasion.
A built-in rechargeable lithium polymer battery delivers up to 3,000 ranges per charge. A QDI (Quick Detach Interface) magnetic harness mount comes in the box, so the KILO MICRO attaches and detaches quickly and can ride on a chest harness or pack strap for fast access.
The Infinite Guarantee covers it for life, with no receipts, no warranty cards and fully transferable coverage.
Knowing the distance matters in more situations than most people expect. For instance for hunters, who can confirm the distance to a deer before deciding whether a shot is within the range of the rifle and cartridge. Range is the starting point for holdover or dial adjustments.
It’s pretty basic that a shooter can verify the distance to steel or paper targets on an unmarked field, so ballistic data can be checked against reality. But once it gets more complicated, like with angle compensation, the device really matters for uphill and downhill shots.
We probably won’t have to persuade most of our readers to own an LRF, but they're great for archery, golfing and hiking and camping as well.
The best rangefinder is the one you actually bring. At 3.4 ounces, the KILO MICRO adds very little to a pack, belt or chest rig, which matters on long stalks or hikes where every ounce counts. Bowhunters in particular carry a lot of gear and need something that stays quiet and out of the way. A compact monocular is also easier to stow and pull out quickly, and the magnetic harness mount keeps it within reach. In SIG Sauer's words, it is small enough to disappear into your kit, yet capable enough to earn its place in it.
