im not an authority on night vision, fairly new to it, but i do have both a thor and a 4kpro .. imo thermal does very little for an advantage on anything at airgun ranges, and i much prefer the high resolution of the 4k infrared .. the highest resolution the average person is going to afford in thermal is 670 and thats high end .. the more economical ones are 160 or 380 resolution .. the 4k is. *drum roll* 1080 resolution .. do the math ... thermal can help pick targets out that are distant is about it .. if anything id buy a larger IR torch you can keep charged easier in maybe 940nm and mount it on a small tripod ... but thats my inexperienced recommendation ..dont waste your money on a thermal unless its for a specific thing like distance, the infrared/ 4k is alot better for most things ..
