Cabelas definitely limits your choices. If it has to be a thermal scope from Cabelas, then the two best options they have are either the Thor 4 or possibly one of the Burris ones. The bad part of that is, I can't reccomend ATN to anyone because my experience has been both quality and service are poor. And the Burris ones are brand new, so IDK much about them. The specs on the Burris BTS-50 look good to me, but alot of thermal performance is software based. They might be worth a try, but you should do more research on them.
Now if you wanted a handheld monocular, and not a riflescope, I would recommend the Pulsar Helion XP50. It has a 640 micron sensor so the image is going to be very good. The magnification is a touch high at 2.5x minimum for using as a scanning device, but not bad. 1-1.5x would be my preference there. And Pulsar is a reputable company that caters to sportsmen first. This would likely be a solid piece of kit worthy of your investment. And you will be surprised how much fun it is to just drive around at night looking out in the fields/woods with thermal. You'll get much more use out of a handheld than a riflescope.
One option you might consider would be purchasing the Pulsar handheld thermal, and then also buying a regular nightvision scope. The upside to night vision on the gun vs thermal is you see actual image of the target, and not a heat blob. That means you can see difference between a coyote vs wolf vs neighbors dog, at distances further away than you can easily do that with thermal. The downside is follow-up shots are much easier with thermal because staying with the running target is effortless. Hence the reason thermal is so popular for hog shooting.
