You might try searching thermal coon hunt and check out a few videos then. Im not really sure about much of the other stuff available but have no doubt that the Iray bolt i picked out for hogs and coyotes would be a great asset for a coon hunter.
I was advised during my search that is be looking at about $2500 to get a decent thermal to fit my needs decent quality and image out to about 200 yards. The late night vision show is pretty informative but they seem quite busy if you call. Dark night outdoors spent well over an hour on the phone answering my questions over multiple conversations. They use these products constantly and are quite knowledgeable. Like other electronic devices it seems capability is constantly going up and prices coming down as the tech progresses.
Good luck. Hope you find the right optic to fit your needs. PS Iray has recently come out with 1280 resolution optics for around $17K �� afraid Id buy once and never stop crying with that one lol
