Sig Sauer KILO 2400 ABS Ballistic Rangefinder Review

I next compared the optics of the KILO 2400 to the G7 BR2. The KILO 2400 features a 7 power x 24mm optic and the G7 BR2 is similar at 7 power x 25mm. I noticed that the eye piece on the G7 BR2 is larger than that of the KILO 2400 making it a little more forgiving when first looking through it and lining up my eye. The KILO 2400 is perfectly fine in this regard but the G7 BR2 was slightly better. The sharpness seemed to be very similar between the two comparing tree branches at long distance.

I also noticed that the G7 BR2 was noticeably brighter. It was midafternoon and bright outside and the KILO 2400 was plenty bright enough, but the G7 BR2 was quite a bit brighter. I made a note to compare them later in the day in low light conditions when the difference might really matter.

The KILO 2400's field of view is stated as 35.67 feet at 100 yards and the G7 BR2 is 330 feet at 1000 yards or 33 feet at 100 yards, so very similar. I compared the two by lining up the edges of their views with the left and right edges of a block of timber in the distance. They looked virtually identical to me. The EL Range field of view is stated as 330 feet at 1100 yards. Comparing them to the edges of the timber I couldn't see any significant difference between them and the others.

I really wanted to compare the ranging ability of the three rangefinders on animals but I did not see any cows or other animals out and about on my way to do my testing. I had brought a 3D buck archery target along and I wanted to find a place where I could set it up and continue to move farther away from it to test the max range capabilities on a target this size and shape. I found a long stretch of straight, quiet road along the edge of the marsh and set the target up on the shoulder.

It was now very sunny and bright and I knew it would be challenging for the rangefinders. I started ranging at approximately 500 yards and all three rangefinders ranged the deer just fine freehand. I moved back several times. The first distance where the rangefinders began to struggle was 769 yards. The EL Range would not pick up the deer. The G7 BR2 would only range it on scan mode after several tries. The KILO 2400 ranged the deer every time whether while scanning or with individual pulses.

As I moved farther back the sun was now beginning to set so the lighting conditions were improving for the rangefinders. At 983 yards freehand the EL Range would not range the deer. The G7 BR2 ranged it but only after several tries. The KILO 2400 ranged the deer on the first or second try repeatedly.

I moved back to 1023 yards and mounted the rangefinders on a tripod. The KILO 2400 and the G7 BR2 performed similarly. They both took several tries to get a range on the deer. At 1108 yards the same was true.

The sun was getting close to setting by now and the conditions were quite dim. I noticed at this time that the image brightness was nearly identical between the G7 BR2 and the KILO 2400. So even though the G7 BR2 was brighter at mid-day, the KILO 2400 was just as bright in low light. The farthest range I was able to get on the deer was at 1240 yards using the KILO 2400 on the third try while mounted on a tripod. The G7 BR2 would not range the deer at this distance.

By the way, Jeff Brozovich from LongRangeOnly.com posted a video review of the KILO 2400 where he says that he was able to range a calf elk (deer size target) at 1406 yards and a reflective road sign at 3180 yards.

I wanted to compare the ballistic solution provided by the KILO to my validated G7 BR2 solution at long range. I was ranging a sign at 1490 yards and couldn't figure out why my G7 BR2 wouldn't give me a solution but then I remembered that the G7 BR2 only provides a ballistic solution out to 1400 yards (the KILO 2400 has no limitation).

I moved closer and at 1390 yards the two devices' solutions were within 1/2 minute. I was pleased with this considering I had spent no time "trueing" or calibrating the KILO's data. I had trued the G7 BR2 in the past.

As the sun set, I ranged from one end of the road to the other, where there was a reflective street sign. The KILO and the G7 BR2 both easily ranged it at 2132 yards, however I couldn't actually see the sign or much of anything through the G7 BR2 because of the low light. I could see it perfectly through the KILO.

On the G7 BR2 the display brightness is adjusted manually while the KILO does it automatically. The kilo also has a much wider range of brightness settings. At the very end of shooting light, the G7 BR2 could not get dim enough to not wash out the image. Add to that the fact that the G7 BR2's reticle is thicker and covers up more of the image, and the KILO 2400 far outperformed in low light.

The automatic brightness adjustment on the KILO 2400 seems to work flawlessly. No matter the lighting conditions on the day I tested, the KILO's display was perfectly visible. This is a huge improvement over the G7 BR2.

I missed an opportunity on a nice muley buck last year when I needed a quick range before the buck left the small opening I had spotted him in. It was mid-morning and very bright. When I tried to use the G7 BR2 I thought it wasn't working at all. Eventually I realized that I couldn't see anything because I had left the display set at its lowest setting early that morning. By the time I adjusted the display brighter, the opportunity was lost.

Final Thoughts On KILO 2400 Optics, Laser and Field Review

I headed out to do my field review hoping that the KILO 2400 would outperform my G7 BR2 and it absolutely did. The KILO's scan mode is outstanding and is an important reason that it outperforms other rangefinders. I can't think of any reason not to always use it on scan mode. The results are instant and it is a great way to know exactly what you are ranging.

The fact that the KILO's laser seems to be perfectly lined up with its reticle is another reason for its outstanding ranging performance. I think the size of the circular reticle and corresponding beam divergence of the laser is just about perfect. Because of the outstanding scan mode, the fact that the beam is smaller than some other rangefinders does not mean that you can't do a good job of ranging freehand. And the relatively small beam means that the max range outperforms most other rangefinders.

I did not have a chance to test the BEST vs LAST target modes, which are designed to help range through brush and grass. I can imagine that understanding them better will improve my ability to range in all kinds of conditions with the KILO 2400 even more.

For me personally, the automatic display brightness adjustment is a game changer. I look forward to never having to think about it ever again…

I am not an ELR shooter so the fact that the KILO has no limitation for how far it will give a ballistic solution is not a big deal for me personally, but I know that many folks are thrilled about it and rightly so.

As far as max range on animals in real world hunting conditions, I look forward to doing much more testing in the future when I get my own personal KILO 2400. I also look forward to seeing what others report about their experience in the LRH forums. There is already a report of ranging a calf elk at 1406 yards (deer sized target 150-200 lbs)

The only slight negatives I can think of are the smaller eyepiece and dimmer optics during daylight conditions. The KILO's optics are perfectly acceptable but the G7 BR2's are slightly better during bright conditions. As I mentioned above, the two were virtually identical in low light conditions when it really matters.

One other slight negative I noticed is that it is hard to feel the RANGE button being depressed when wearing gloves. I would prefer a more noticeable click when depressing it.
