I've been reading up on optics.

Thermal?? Seems very interesting. Do these work indoors??

I'm preparing to get into optics, at least for me, in a major way.
My eyes are not what they use to be. I own it.

So, I need a good mix of stuff. It teaches me what I like and don't like.
Red dots and thermal have my attention.

Thor??? Is this a reliable brand??
Brownell's has a sale and it's in stock.

ETA: This is what I'm looking at:
4-8x Thor-LT Thermal Scope W/ 30mm 0 MOA DC QDM Mount

I was thinking since I have those two A4's, one could have thermal ability.
The other outfitted with typical A4 optic.

ETA2: I'm not interested in legacy optics.
Latest and greatest please!!

Opinions please.

TIA

Yes, they’ll work indoors, but they’re not really suited to the role of a general purpose optic nor are they really the best choice for something like clearing a structure.  They can’t see through glass, generally have a relatively small FOV compared to something like an RDS, there is some lag/latency with quick movement in a lot of units, most options won’t have a true “1x” image, and they’re really expensive (compared to something like an RDS).

A thermal scope would be a good choice in a low/no light environment where you need to detect living objects that may be camouflaged/concealed, usually with at least some distance between you and a potential target.

ETA:  No, that ATN product is absolute bottom of the barrel in the thermal world and ATN is known for absolute shit customer service and generally unreliable products.

If you’re looking for a thermal scope, figure on budgeting $2k-$2.5k at the minimum for a quality budget option.  Even then, you’re going to be getting a Chinese core and 320 resolution.
