It really is everything they promised. It is crystal clear from edge to edge. Easy to adjust. FOV on my 65mm is sufficient for my PRS matches. I can see hits all the way to 1,000 y. Sometime mirage is there but not the optic's fault. Basically if you can afford it...go for it...you'll love it!

I purchased the Swarovski BTX along with the 115mm objective for long range observation during hunting bighorn sheep, elk, Coues deer, mule deer, pronghorn, etc. Together this combination is outstanding in quality! I thought I would have a hard time getting used to glassing with my head pointed downward, as I typically glass with 15x56 Swarovski Binoculars mounted on a tripod looking in the straight view position. But I was surprised that it was actually easier on my neck and back to glass with the head pointed downward. The image is crisp, clear, and brings in so much light, as to be expected with all Swarovski glass. Do realize that with the further distances over a mile, you will get a lot of mirage or the heat waves are magnified, but that's not the fault of the glass. Even with the heat waves magnified in 85 degrees, I was able to glass up a herd of desert sheep at 3.18 miles away! This set up will be a game changer in your long range hunting arsenal! Overall, it was a great purchase and I highly recommend this set up!
