Sig Sauer Kilo 2400 ABS Rangefinder Review

By Justin Crossley, Rokslide Assistant Editor

Whether I’m hunting with a rifle, bow, or muzzleloader, the most important piece of information needed when it’s time to shoot is the range to the target. As other variables are added such as angle of shot, wind, temperature, and other environmental factors, I need to know even more information to make an accurate shot. This is most important as ranges increase, and never more important than when taking a long range shot with a rifle. In the past, I used multiple tools to gather all this information and then input it into a ballistic solver or drop chart to get a firing solution. That worked OK but took time that I sometimes didn’t have when hunting. The Sig Sauer Kilo 2400 ABS Rangefinder was designed to automatically give a firing solution with the press of a button and save the shooter a lot of time when it matters most.

I had my order in before the Sig Sauer Kilo 2400 was even available and couldn’t wait to see if it would be the rangefinder solution for all my hunting and shooting needs. When it finally arrived, I didn’t waste any time taking it out of the box and getting it ready to use.

In the Box

Inside, I found the Sig Sauer Kilo 2400 rangefinder, manual, field case, three batteries, wind meter, tripod adapter, lanyard, pen/stylus, and a soft-sided zippered case to hold everything safely and organized inside.

Externally, the Sig Sauer Kilo 2400 is pretty simple.

You’ll find only two buttons which I was able to use with one hand after getting familiar with the unit. The power/range button on top, and the mode button located on the side. There is a spot to attach the lanyard, a screw in battery door, adjustable eyecup, and diopter focus ring. The housing is magnesium with rubber armor at the top and bottom. Overall I feel the size, weight, and ergonomics of the Kilo 2400 are just right.

Some key features of the Sig Sauer Kilo 2400

  • Store up to four profiles on the device and 100 in the App
  • G1, G7, and custom drag models available
  • Muzzle velocity temp table allows the unit to adjust for velocity shift with a temp shift
  • HyperScan refreshes 4X per second
  • OLED display with automatic or choose from nine brightness levels
  • WeatherFlow audio jack wind meter is included to get wind speed and direction or input speed and direction manually.
  • First, Last, and Best target modes
  • Angle Modified Range (AMR) can be turned on or off
  • Line of Sight mode (no inclination calculation adjustment)
  • Target speed and direction can be input via the app for calculation of the firing solution
  • Override current sensor readings and manually input Temp, Pressure, Direction of fire etc.

My Experience

There are so many features included in the Kilo 2400 that it’s hard to find a place to start. I found the laser powerful enough to get consistent range readings way past my own personal hunting needs. Ranges from 5-2000 yards are no problem and the speed is very impressive. The only time I had an issue getting a range was in a fairly heavy snow shower. I kept getting much shorter readings than the actual distance to the target. The Kilo will give angle compensation and/or a correction for any range it can get a reading of. This is great because it makes it truly usable for everything from archery to long range rifle hunting.

I found the app simple enough to use and had a profile loaded and synced with the Kilo without any trouble. As mentioned above, the app can store 100 profiles and the Kilo 2400 is capable of storing four at a time which you can switch between using the mode button. Unfortunately, you can’t name the profiles in the rangefinder which would make it much easier to confirm you’re using the right one.

Test Time

The first chance I had to use the Sig Sauer Kilo 2400 on a hunt was a late winter, solo coyote hunt. Calling predators can be fast and furious so I typically range all my possible shots before I start the call. On this particular set, I had a male approach from an unexpected direction but the speed of the Sig made it easy to get a range and make a quick kill shot at 184 yards.

Next up was spring bear in Idaho. On this hunt, I spotted a cow elk bedded 1450 yards away and was quickly able to get a range and firing solution. I obviously wasn’t hunting elk but this was a great test in real conditions.

A few days later I found myself perched prone on an overlook as I attempted to call in a wolf for my friend Jeff Brozovich (owner of Long Range Only). Before starting the call, Jeff took a few seconds to range all the possible locations where a wolf may show itself and pre-dialed his scope so he would be ready. I fired up my FoxPro and let it play for just under a minute before turning it off. After just a few seconds a big male wolf stepped into view at 176 yards and Jeff was able to make a great clean kill shot.

Bear hunting was really rough due to late snow melt but on one of the last days, my friend Billy George spotted a bear feeding about 1500 yards away. We ranged the bear and attempted to get Billy setup but the bear didn’t stick around long enough for an ethical shot. Afterward, Billy and I decided to test ourselves and our gear by shooting a rock near where the bear had been. I missed my wind call slightly but the elevation solution from the Sig Sauer Kilo 2400 ABS was spot on.  After a windage correction I was right on target.

Fast forward to October and I was on my first antelope hunt. This was just the scenario I needed to really test the Sig Sauer Kilo 2400. The first thing opening morning we were crawling toward a herd. We got within range (about 250 yards) and my buddy Rob Melvin ranged his buck and made a great shot. The herd scattered and I ranged a buck that stopped. The Kilo instantly gave me an accurate range and the elevation adjustment I needed to make a clean kill. I quickly dialed, squeezed the trigger on my Christensen Arms Mesa and my buck was dead in his tracks. Again the antelope ran and when they stopped, Rob picked out a big doe. He ranged her with his 2400, dialed, and made another great shot. Within a matter of about a minute, we were able to get accurate ranges and elevation corrections so we could make three clean kills. I know without a doubt that our Sig rangefinders played a big roll in our success that morning.


Over the last year, I have used the Sig Sauer Kilo 2400 for everything from archery hunting, muzzleloader hunting, rifle hunting, and long range rifle practice. The Kilo has continued to impress with fast, accurate readings along with accurate firing solutions. While the price of the rangefinder may be more than some can or are willing to pay, I am confident in recommending it as the best all-around rangefinder I have personally used.
