Sig Kilo 2400 – Ultimate Tool or Not?

In Blog by Rich16 Comments

You may or may not be following the development of the Sig Kilo 2400 laser rangefinder. I for one, have been following it closely. I’ve had high hopes for this device and as time has progressed more and more information has been coming forth about it. There are those segments of our sport that will buy it immediately because they have to have the newest, shiniest, whateverest device on the market. Then there are those of us who may not find it as appealing. This week we’re going to talk a bit about the device, what we know so far, what we’d like, and what to expect!

Sig Kilo 2400

The Sig Kilo 2400 is the sequel to the well regarded and successful Sig Kilo 2000 laser rangefinder. The Kilo 2000 is a current favorite pick in the long range shooting community offering excellent rangefinder performance out to around 1000 yards. For most people, including competitive shooters, this is more than enough rangefinder to range and engage whatever they come across. The device retails for around $500 and was typically seen selling for around $420. It has recently been on sale and if you can find one that hasn’t already been sold you’re likely to be able to snag one for around $350. A buddy of mine just bought one and it’s a lot of bang for buck at $350.

The Sig Kilo 2000…the LRF that started this experiment!

There are two rumored successors, the Sig Kilo 2200MR and the Sig Kilo 2400AB. The 2200MR is supposed to be roughly (around a 5% improvement in ranging ability) the same guts and rangefinding capability paired with a Milling Reticle. Hence the “MR” designation. The 2400AB is to be the new flagship device. This one is going to have built in sensors for barometric pressure, temperature, etc. and have the Applied Ballistics solver built into the rangefinder. If that doesn’t already raise an eyebrow, it should. We’re talking about the consolidation of devices here. The Sig Kilo 2400 is going to be a “one device does it all” offering. A shooter will load a weapon and bullet profile via Bluetooth from a phone. Then when a target is ranged, the Sig Kilo 2400 will use the onboard sensors and Applied Ballistics solver to do all the firing solution math on the spot.

I’ve asked a lot about what is displayed and how that works. Apparently, it will display the range along with the elevation adjustment needed for that range. More importantly it will also display the wind correction needed. The Bushnell ConX was a similar attempt at the same idea but only displayed the range needed and not the wind hold. I’m told you manually set the wind in the rangefinder like a preset of sorts. Which is fine because I’ve always advocated using a 10mph Full Falue Wind as a baseline and modifying that number to suit your conditions.

Sig Kilo 2400 Advancements

I’m going to say this now, the Sig Kilo 2400 will be a real technical achievement when it debuts at SHOT Show 2017. A device that allows you to range and get a firing solution with the press of a button is more than impressive. I think for the folks out there that have yet to invest in a Kestrel the Sig Kilo 2400 is probably going to be the way to go. The Sig Kilo 2400 is supposed to retail for around $1700 but I have seen the guys at are taking pre-orders for the Sig Kilo 2400 at MAP (Minimum Advertised Price) of $1500. If you consider that a Kestrel with the same sensor package needed for ballistic solutions and the Applied Ballistics solver run around $700 by themselves the price of the rangefinder on top of that is only around $800. That’s well inline with similar offerings from Leica and other LRF manufacturers.

Long Range Hunting gets the photo credit and they’re taking pre-orders if you’re interested!

I can tell you, having read Modern Advancements in Long Range Shooting Vol. 2, that the Sig Kilo 2400 is an outstanding rangefinder. It performed almost as well as the Vectronix Terrapin which costs another $500 more than the Sig Kilo 2400. All the Terrapin does is range, it doesn’t have the added benefits of a sensor package and ballistics solver built into it. I was initially curious as to how you would record your environmental conditions at the range when using the Sig Kilo 2400. It may be possible to view the sensor readings from the phone app. That’s a question I’ve yet to see answered. So all in all, after some disappointment on my end I’ve come to see this as a pretty cool device that’s likely a good buy for people that can swing it and are ready to step up their game.

The Disappointment

I mentioned it and now I’ll explain it. I like the guys at Applied Ballistics. I think they do a LOT of really impressive work. Their laser rangefinder testing was more than impressive. Their dedication to measuring and recording ballistics coefficients for bullets on the market is one of a kind. So the issue for me? I was really hoping to see the Applied Ballistics Kestrel 5700 utilized with this new rangefinder technology. I would really like to see a version of the Sig Kilo 2400 with a bluetooth connection but without the built in solver and sensor package. I’d like to see that rangefinder priced lower. I’d like to see it communicate with the Kestrel 5700 for the ballistics solution and all the environmental readings. Similar to the Bushnell ConX but with the Sig Kilo rangefinding capability and both elevation and wind holds displayed.

This issue for me is I’ve spent some good money on Applied Ballistics products in my time. A $40 dollar phone app. A $700 dollar Kestrel 4500, and most recently, a $700 dollar Kestrel 5700. I upgraded to the Kestrel 5700 because it uses Bluetooth Low Energy and I figured it would be the device the Applied Ballistics guys would incorporate into future projects. Now it seems it’s been left out. If I want the new super cool do it all rangefinder, I’m essentially paying for a solver, sensor package, and custom drag library I’ve already bought twice in the past. There’s an element of what feels like disloyalty there for me. I feel like a loyal customer who’s been left out of the invitation list for the cool company party. Hopefully in the future we’ll see a version of the Sig Kilo 2400 that does something like what I’ve described here!

Wrapping Up

I think the Sig Kilo 2400 is going to be a pretty cool gizmo. It comes with everything you need to range and engage targets out to well beyond 1000 yards. It’s damn cool and I admit that. I think it makes the most sense for people who haven’t already invested in an Applied Ballistics Kestrel. If you’ve already bought one I think you’re better off waiting to see if something like I’ve been talking about comes to market. I hope the Applied Ballistics guys find a way to include the Kestrel in a “do it all” rangefinder solution in the future. I’ll be honest, I’ve been skeptical and even critical of this device. The more I read, the more I’m impressed, but also that feeling of disappointment finds me when I realize my trusty Kestrel wasn’t included.

Again, I think this will be a great device for guys who haven’t already invested in the Kestrel. For those of us who already invested in the Kestrel, let’s try not to let it make us feel too jaded. Let’s try to keep an open mind. I’ve found once I set my disappointment aside that the value and impressiveness of the Sig Kilo 2400 become more apparent. With a little luck I’ll be able to find one to play with a little bit for a follow up article in the future.

  1. First a tip (as someone who has a Kilo2000 and was disappointed in that it really isn’t any better than the Elite 1-Mile I had to replace): tape a sheet of foil to your target for the reflection it provides. Using this trick, I’m getting excellent, accurate, repeatable, readings out beyond 1300 yards (and hoping it will get me past 1700).

    (wouldn’t help if you’re trying to range elk out that far…)

    Now on to this article: I don’t like all-in-ones. In my real world, the wind doesn’t blow at 10 mph from 9:00. At 300 yards, it may be blowing [email protected]:00, at 700 yards, it may be blowing [email protected]:30, etc. The ballistic calculator on my tablet let me play “what if” games with the numbers very easily, and then I have to use my brain to try and tie all those different readings into the hold-off I’m going to do when I pull the trigger.

    Tell me how you can do this easily in the new Kilo and maybe I’ll start saving up for it.

      The technology is neat, whether it works for you is sure to be an individual choice. What calculator are you using on your tablet?

      I like the idea of consolidated devices but it has to be done in such a way that you can still access all the features. I’m sure more information will be forthcoming as this thing is officially released.

      I still yearn for a ConX type setup executed with a better rangefinder and displaying the appropriate information.

      Sorry Nick, you got trapped in the spam filter. I’ll take you up on that, I have a couple questions about the 2400 and maybe one or two about future products!

  2. Have you brought up any of your dislikes with Sig? I believe it is technically their product not AB’s. They just use their solver…correct?

    1. Author

      I’ve asked a few people about a point of contact for SIG. I had a good conversation with Nick Vitalbo of AB who made a similar point.

      They have some say but generally get contacted about including their solver in another company’s product. They don’t drive the whole project.

      Till now I was under the impression the Kilo 2200 was the same rangefinder minus the sensors, solver, and Bluetooth. It’s not. It’s an uodated Kilo 2000 with a milling reticle but the ranging hardware is not as powerful as what’s in the Kilo 2400.

      I think SIG would sell these like hotcakes if they made a “Kilo 2350” or something with the ranging hardware from the 2400 that pulled all the atmospheric data from the AB Kestrel and got the firing solutions from the AB Kestrel as well.

      AB has a project or two in the works that look really promising. We Kestrel owners just have to be patient.

  3. Regarding the AB/Kestrel/Sig integration.

    I think it is important to remember that Kestrel (Nielson Kellerman) and Sig are two separate companies, both licensing a third companies (AB) software to run on their hardware.

    It’s more a case of Kestrel and Sig working together.

    I too, would love the two to talk. Or, as mentioned, drop the solver in the Sig but have it pull and display all the data off the Kestrel.

  4. Personally, I want to see a QUALITY binocular & quality range finder (my geovid doesn’t cut it) one that actually ranges correctly and has a AB solution. I like my Kestrel 5700 but if i can get it all in one device 🙂 This Kilo sounds like the real deal but i want a Binocular so i don’t have to carry two optics when hunting. I will wait, someone is going to step up…

      Here’s the way I look at this, you HAVE to have a Kestrel with you for wind speed, density altitude changes, etc. When the AB guys first partnered with Neilsen Kellerman to integrate the solver in the Kestrel one big selling point was the Kestrel being a rugged device.

      Water and weather don’t bother it, there’s a wider range of operating temperatures than…you guessed it, a cell phone.

      Now we’ve taken a step backwards because you need a phone to look at environmental conditions from the Kilo 2400. You also can’t get wind speed without a phone and the Weatherflow meter.

      You’re always going to need two devices, I think the debate has become…which two make the most sense?

  5. When I look at the Kestrel website I see a huge variety of sensors that are all basically the same with a variety of software for different industries…when is someone going to get a clue, buy Kestrel and incorporate their way better sensors into an excellent ruggedized cell phone that can add a huge variety of software packages for all these industries at will? It’s obvious…going to happen…why can’t they do it yesterday… 😉 Or make a Kestrel phone dock…that attaches to most any phone….

  6. The Kilo 2200MR is not just a 2000 with a milling reticle. It is an upgraded laser diode that goes 5-10% further than the 2000. Best part… Same map price as 2000.

    1. Author

      About 5% farther, you’re correct and I’ve updated the article to add the improvement for the clarity of other readers! Thanks, Benjamin!

  7. There’s always going to be the next best thing and you can’t look at it like the company is being disloyal to you because a new product came out and just outdated your’s. When Kestrel releases their next wind meter that better than the 5700; what are you going to do? Buy it!

      I agree, Steve. In fact I reached out to one of the AB guys and had a great discussion about it. He helped arrange some hands on time with a 2400 and I did an in depth review of it. It’s an amazing device!
