Just felt compelled to give my opinion on this. Purchased one from UNV after renting one and after less than a minute looking through it I knew I was going to buy it. Had a FLIR 24 previously; which is a quality product and I was happy with but this was outstanding. Haven't looked through anyting first hand other than these two but detection range with this was far better than I'ld have hoped for even without the 2x. I could detect a dear size animal easily at 1/2 mile and coyote size (which is what I want at 400 to 500 yds. easily. Haven't had a chance to detect them beyond that yet but am sure it will. Adustments for brightness and contrast are great and selecting one of the preset modes is usually all I use. Has battery packs so you can change out in the field if needed, rotational built in lens cover and great case. They even offer a Pelican type hard case for free. This has taken detection to another level for me. Fabulous is all I can say for the money.
