Thermal @ 385 res is very solid. Prices are getting low.
640 res is great but 385 gets you 90% on a weapon sight. In a way I might say 385 res is a 6X day scope and 640 res is a 10X.
Not much extra gets done with a 10X day scope.
AGM Rattlers @ 385 res are very good buys.
As other have said for NV a powerful IR light makes even cheaper night vision work pretty well. Coyotes and pigs don't care if you are emiting lots of IR energy, it's not a battle field.
The super power of being able to see in the dark is getting cheaper.
lol. Coyotes and pigs have definitely been accustomed to IR lights now.
Thats why I switched to thermal a few years ago
