Long-range shooting has surged in popularity in recent years, thanks in-part to technological advancements in rangefinding units that have taken some of the mystery work out of hitting targets at extreme distances. Laser rangefinders, ballistic software, DOPE cards and wind metering devices have revolutionized the way shooters address long-range shooting problems. The KILO 2400 ABS Applied Ballistics System Rangefinder from Sig Sauer combines each of these important tools into a single integrated system that is simply the best unit for long-range shooting I have tried.
Three Tools In One
What makes this rangefinder different from the rest? Let me provide a practical example: a few months ago, I was test-driving a precision rifle on a range with targets out to just under 1000 yards. My process was to establish my range to the target with my rangefinder, determine the wind with my Kestrel, enter all of the environmental conditions into a ballistic app, and then make the necessary elevation and windage holds to make the shot. Using the three devices in-sequence, I had all the information that I needed. At the time, this was absolutely cutting-edge rangefinder technology — I couldn't imagine things getting any easier.
Fast-forward to today, and I prepare to make the same shot with the Sig KILO 2400. The 7x25mm rangefinder gives me a range to the target, inputs its own environmentals, connects with the wind meter via Bluetooth connection and, using Applied Ballistics Systems software, gives me a firing solution based on the rifle profile that I've already uploaded to the unit.
Easy To Use
One press of the "range" button provides the distance to the target. Simply release the button when you have ranged your target and the unit will rotate from yardage read out, to elevation hold (in MILs or MOA), to windage hold and will keep cycling through until you range another target. The same information is synced onto my smart phone, but there's no need to consult it since the data is presented on the rangefinder's display screen. Instead of clumsily working my way through several steps with numerous devices, the KILO 2400 gets it all done in one package. In fact, I don't even need to have my smartphone with me — it's only necessary to upload my rifle and load profile into the rangefinder unit. So, when my iPhone battery goes dead three days into a 12-day hunt, there's no problem. Four different profiles can be saved onto the unit at one time while 100 more can be stored on the App.
Unmatched Rangefinding Capability
Two years ago, I tested five compact rangefinders and ranked their performance in several key areas: ergonomics, accuracy, speed, optical clarity, and ranging ability. When the KILO 2400 arrived for this test, I put it through the exact same set of tests to see how it measured up as a rangefinder, not counting its advanced ballistic features. The KILO would have ranked number one in every single category that we measured during our 2015 test. As a matter of fact, I ran out of wide open spaces in which to test this unit before I ran out of its ability to range objects — I finally took it to the beach where I was able to achieve repeatable readings on targets more than 2500 yards away. This unit is simply the fastest, most-accurate, and reliable rangefinder that I have ever tested, bar none.
In addition to the fundamentals of the unit, it includes numerous features that few, if any, of its competitors can claim. It includes ballistic software from Applied Ballistic Systems, a company recognized by the industry and long-range shooting community as being at the absolute cutting edge. The G1/G7 and Custom Drag Models allow end-user flexibility when developing a load profile to ensure that the data is as exact as possible. If the shooter doesn't have access to a chronograph to determine muzzle velocity, the system allows the user to input bullet drop data and it will establish a precise velocity for the load. Built-in sensors record and calculate inputs such as temperature, humidity, altitude and barometric pressure and calculate those factors along with spin-drift, Coriolis Effect and even muzzle velocity temperature shift in preparing shot data — all in a fraction of a second.
The unit also calculates the shot angle and automatically includes that information in the holdover. Another unique feature is the "scan mode", which provides real-time data on moving targets when the range button is held down. A spotter can give the shooter constant updates using this technology. Finally, if the shooter prefers, the rangefinder can be mounted to a tripod and controlled with the remote ranging button using the smartphone app.
A Handy Kit
The KILO 2400 ABS comes as a compete kit, with everything needed to maximize the use of the system. The kit consists of the rangefinder unit, a nylon case and lanyard, the WeatherFlow wind meter and its protective case, an aluminum mount for tripod use, and a Sig Sauer tactical pen, which doubles as a smart phone stylus. The entire kit fits into a Coyote Brown MOLLE case, which includes slots for spare batteries. An easy-to-use instruction manual serves as a step-by-step guide for maximizing the myriad features that are included in the system.
It seems as though every company is trying to wedge itself into the long-range shooting world. I begrudge none of them. The reality is, though, that it takes real precision equipment to connect with targets once you surpass about 800 yards. Sig Sauer did it right when they created the KILO 2400 ABS rangefinder — this product is the most effective consumer long-range ballistic system that I am aware of. The combination of quality components assembled in the U.S. with Applied Ballistic Systems software provides a simple, fast and accurate unit that gives shooters the best in real-time solutions without fumbling with multiple devices. When Sig Sauer stepped into this market, they did so in a big way.
