I have the 4k in 3-14x and I like it. It’s a real step up from the X-Sight 2 which I also had. The battery life of the 4k is fantastic. If only other scope makers would do the same. Also, the eye relief is much better than the older second generation model. The 4k is very light sensitive and as such sometimes doesn’t have contrast like I would hope for, to better distinguish the target animal from the background. It isn’t that bad but could be better. I was using a more powerful TR-38 850nm light and found that stepping down to a Uniquefire T-20 actually does a little better with contrast. The 4k has onboard recording WITH SOUND that works well. A simple push of a button on top of the scope activates recording and another push stops it.
As to the Wraith, I have been very interested in hearing / seeing reviews and figured I would purchase one later unless reviews are not good. The resolution appears to be really good according to specs, better than any other digital. However, I recently learned that while it does have onboard recording, it DOES NOT HAVE SOUND. That one thing has lessened its appeal to me. The scope (from the specs) seems to be a step up in digital and from all appearances has the potential to be top notch. Why Sightmark would neglect sound when designing a brand new scope from the ground up, beats me. It’s like they set out to produce a top tier digital but left out an important feature that hunters want. You could record sound with another device, maybe a phone, and edit it in, but that’s just one more device to have to get operational in the heat of the moment when a coyote is coming in fast. Plus, it requires additional work with editing and getting sound and video synchronized. I also wish onboard battery life was better, but at least it accepts an external battery.
The Wraith may be such a good scope that many will be satisfied with it as is, without sound, but hopefully Sightmark will recognize their mistake and bring sound to new models.
Just my two cents worth.
