Ballistic Solver App

KILO2400ABS syncs with a smart phone via the Applied Ballistic's Ballistic Solver app. Calculating long-range rifle trajectories for the perfect shot. (Smart phone app display shown.)

Lightwave DSP

Lightwave DSPTM (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.

Angle Modified Range (AMR)

AMR is advanced ranging technology using an on board inclinometer that reads incline/decline angle and modifies the effective ballistic shooting range to the target.

Electro-Optics Technology

We have developed truly game changing optics for all types of shooters: military, law enforcement, hunters, and competitive shooters.

  • AMR™ Icon


    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.

  • Infinite Guarantee™ Icon

    Infinite Guarantee

    SIG SAUER Electro-Optics are guaranteed forever. It's an unlimited lifetime guarantee.

  • LightWave DSP™ Icon

    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™ Icon


    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.

  • SpectraCoat™ Icon


    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.

  • Stealth ID™ Icon

    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.

  • 5 Year Warranty Icon

    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.

• Customizable Reticle allows you to change the look of the reticle by adding/removing parts of the milling grid.
• Advanced OLED display provides a smaller, extremely precise targeting circle along with milling features and ballistic info including holdover, angle, wind direction, wind speed, target mode, density altitude and shot angle. 
• Digital Compass / Magnetometer / Inclinometer provides magnetic heading and incline for long distance shooting and Coriolis adjustment.
• Line of Sight or Angle Modified range in addition to full ballistic holdover and windage results in MIL or MOA. 
• LumaticTM Display automatically calibrates display brightness to changing ambient light conditions. 
• 3 Operating Modes: Target Mode for first, last or best options; AMR Mode where Angle Modified Range (Inclination) can be turned on/off; and LOS Mode for Line Of Sight (No inclination calculation adjustment).
• Compact, lightweight magnesium housing with binocular style eyecup and diopter adjustment. 
• Sensor Override: Ability to override the current sensor readings and input your own parameters such as Temp, Pressure, Direction of Fire etc.
• Metric support
Unique Housing/Color: Magnesium, Flat Dark Earth, with Applied Ballistics Medallion.
• Sleek design for one-handed operation and lanyard attachment. 
Adjustable Timeout – Adjust the timeout on the LRF from the app to 30(Default), 60, or 180 seconds.

KILO2400ABS is rated 4.0 out of 5 by 5.
Rated 3 out of 5 by from Direct Mount wind meter Not having a direct plug-in for the wind meter is really an oversight. It comes w a tripod adapter in the first place, so having the wind meter plug in to a tripod mounted rangefinder gives a completely stable and simple setup. Having to plug it into a smartphone which doesn't have a jack, requiring an adapter, that then lays horizontally on the ground when the phone is put down (giving you NO wind read) is really stupid. Plus asking for more confusion and wasted time having to fool around with two devices and a phone interface. Completely impractical in a hunting scenario. Fix this and you'll get my $ in a heartbeat.

Rated 4 out of 5 by from Put a jack on the range finder for the Wind Meter! Works great but it having the wind meter attach to the rangefinder would be a huge upgrade and simplify the fire solution process.

Rated 4 out of 5 by from Great Kit - But Caution Advised Bought Kilo2400ABS Elite at GREAT price....makes me wonder if it is about to be discontinued or updated???. Unit functions well with typical care needed to range objects at long range. AB function works duplicative of Kestrel 5700. Tripod adapter is fixed size and is difficult to insert Kilo into.....interference with rubber on Kilo. Should be designed to open widely with a tightening feature.....poor design. I scrapped the adapter and made my own which functions better. Interfaces with Kestrel 5700 for ranging input which is major benefit. ONE CAUTION!!! The ballistic profiles in Kilo are only differentiated by numbers 1, 2, 3, and 4. I see a great opportunity for selecting the incorrect profile and sending a round off target.....and more serious....out of the range/over a berm. Talked with Sig rep who thought that was impossible....NOT!!! Warned our gun club member roster to use caution that they select the correct profile....and double/triple they own every round until berm impact. Otherwise a great addition to my kit. Nice case included. Anometer included probably will never be used as I have the Kedtrel5700 Elite also.....lower price offer as option. Probably would have been money better spent to cry a little more to buy the Vectronix Terrapin X rangefinder....more range/less beam dispersion/better NVista performance rating... which also links to Kestrel and use the 10 profile clearly named profile capability of the Kestrel 5700ABS. Still glad I bought...I'm a gadget freak without adult supervision in my life. :) :) :)

Rated 4 out of 5 by from Great product but with two cautions I bought it for hunting and as soon as at home struggled two hours or more attempting to load my guns profiles. Each time after having FIRST chosed the right caliber ans filled tha aps profile with correct data all my input where rapidly erased. Ended up being a sort of incompatibility with my Sony Xperia Cellphone. Data loaded via an old Samsung have being correcly stored. Secondv I still cannot figure the correct formula for writing the rifles twist rate nor imperial or metrics. XX. XX as appear in the page has no meaning and there is no explaining on instructions

Rated 5 out of 5 by from FAST INFORMATION I saw these range finders at the Portland Oregon Sports Show and had to have this new technology for my hunting. The support staff was so helpful and knowledgeable. It was very easy to enter my rifle/bullet/ballistic date. I went shooting with my KILO2400ABS and was hitting targets with one shot out to 1000 yards. I love how fast it gives me the information to make my scope adjustments so I can hit the target. I liked the SIG product so much I bought ZULU5 12X50 binoculars.
