Caterpillar has a smartphone with a thermal camera. The price isn't far off the the price of the most expensive smartphones

There are also cheap ($200-$400 range) usb-c thermal cameras specifically for phone use (they're cheap because they're just a sensor, the app on the phone is the "screen" and controls.) Great for narrowing down overheating hardware, and you can keep one in a pocket.

I will say I have a FLIR C5 dedicated thermal camera, which I got used off Ebay for ~$300, and it's pretty useful to have around as a DIYer.

Thermal is interesting, but hyperspectral is much wider than just thermal. The two are not the same.

how does Cat's self repair policy compare to John Deere's? Then again, it's not far off from Apple's
