Spotters Sig Kilo10K Gen 2, AB Quantum app, Sig BDX app first impressions and comments

[m1match]

I just got an Sig Kilo10K Gen 2 and my first impressions of the are very favorable. The past few years I've been using a Leica 3200.com 10x42 except for the Nightforce ELR match when I bring my old trusty Vectronix Terrapin. I use a Kestrell 5700 Elite for my ballistic solutions. I used to have an Sig 3000BDX, but the glass annoyed me, too blue and the lack of contrast made finding hunter targets a lot more difficult. The Leica has great glass, an acceptable laser rangefinder for most uses, but the ballistic software wasn't good enough, and the laser has an annoying delay that you have to endure before you can take another range reading.

The Kilo 10K Gen 2 has much better glass than my old 3000BDX, the image isn't as sharp or contrasty as the Leica, but it's pretty good as is resolution. For me it should be good enough to use as a spotter for most ranges under 1000 yds. The electronics is blazingly fast and the LED display is outstanding in its configurability and displaying all the info that you want. The user interface is pretty intuitive, even the wind correction interface to change direction and velocity of wind. I ranged targets out to about 2000 yds easily, and was able to range a car and a small shed at over 4000 yards, which I think is very impressive. The ability to adjust the reticle to match the laser location is excellent and using poles that were far away, I was able to adjust it so the laser matches the reticle very well.

I tried out BDX Elite which uses the onboard AB Elite software and it works as expected. I also used it set to BDX External connected to my Kestrel 5700 Elite and again it worked seamlessly and as expected.

The software interface with the app worked well but here's where I want to see improvement. I downloaded the Sig BDX app AND the new Applied Ballistics Quantum app onto my iPhone 15. You need to use the Sig BDX app to adjust the reticle to laser alignment and although you can configure the rest of the settings in the unit, it's easier to use the app to configure those settings. The Sig BDX also has the ability to create and sync custom gun profiles, but the AB bullet library in the Sig app isn't complete and doesn't have data for many bullets, like the Berger .264 144 LRHT, which is what I'm shooting. The new AB Quantum app is brand new and I like the new interface. It pairs with the Kilo 10Ks seamlessly and syncing custom gun profiles is easy. It has the complete AB bullet library. What it doesn't have yet (AB says it's coming soon) is compatibility with the Kestrel 5700 Elite. All of my various gun/bullet/load combos are currently set up on my Kestrel and on the Kestrel LINK Ballistics app on the phone and what this means is that I can't import all of those existing custom gun profiles to the AB Quantum app and then get them on my Kilo 10Ks. Also since you can sync to both the Sig BDX app and the AB Quantum app, when you use one app to sync, it erases the profiles that the other app put on the Kilo 10k, rather than merge the data, which is really annoying.

I think that when the AB Quantum app gets Kestrel compatibility I'm going to bring all my custom gun profiles from the Kestrel to the Quantum app and use only that app to sync to my Kilos. But until then I think I'll use BDX External mode connected to my Kestrel during matches.
