FLIR Scout TKx: My Impression
The FLIR Scout TKx feels like the more refined option to me. If I want a better overall experience and more usable viewing time, I would lean toward the TKx. It still keeps the same compact style, but it gives me a little more confidence when I need to observe targets for longer periods.
I would choose the TKx if I want:

If portability matters most: Both are good, but I still like how easy it is to carry either one.
My Practical Buying Advice
