The cost of a thermal scope varies widely, but none of them are what most people would consider to be cheap. You can find some under the $1,000 price point, but those are rare to find. And if you’ve only got a grand in the budget, you’d be better served to save up a bit more. Most thermal scopes on the market will cost at least $2,000 and some even cost more than $5,000. Models that come in at $10,000 are not out of the question.
