i like the Thor4, couple things - you wont need high power for airgunning, and the thor is awesome in the focus dept, down to like 10 'feet' .. also to throw it in there, if you have 'no' night vision, a thermal is not usually the most ideal or 'best' to use most of the time. resolution on any thermal you can afford will be less than half of a 4kpro infrared .. 'alot' less detailed, and not near as good of a picture ...so is it worth 3X as much as a 4kpro just because its thermal? not even if it was the same price .. thermal isnt all that and a bag of tater chips imo .. in 'some' situations, very few, its a slight advantage, but only you know that ... the 4k has a color normal day mode to, which makes it a viable option in the day with all the bells and whistles, nice recording, active ballistics and ranging etc
