How do you find yourself a lath? Try once if it doesn't hit then move up/down a 3/4 inch.

You can see it on a thermal camera with a high resolution sensor from China (not the ITAR limited US tech).

Got a link? This sounds handy.

Thermal Master P3: 25fps, 256x192, manual focus

Looks like it's improved even further - I'm seeing that model listed with 512x384 resolution, and it's $300 on Amazon.

Pretty incredible! I felt like I was getting an amazing deal when I paid about $1000 15 years ago for a FLIR E4 that I could flash into an E8. I might finally retire that in favour of one of these.

That's the software upscaled size, not the real resolution. Typical distortions of East Asian marketing.

I would be amused if the actual reason for upscaling is that a 256x192 display is hard to source and that the firmware is partially shared between models with a display and models without one.

It connects to a cell phone for display so the image is scaled either way. The issue is how the chosen algorithm may be adding non-existent detail or not. If you disable the enhancement you get nearest-neighbor. The true sensor size is all that really matters. Flir has nothing in this segment that comes close to that.

Pretty much but the wall is mostly lathe so you usually hit first go.
