I'm relatively new to thermal scopes I've owned one for about a year. My question is I have read that when you magnify a 640 core once it roughly becomes the same as a 320 core. A 640 core has roughly 306,000 pixels at 2× if it's cut in half that is roughly 156,000 pixels, a 320 core has roughly 76,000 pixels. I'm lost in this somehow seems the 640 at 2× should be much better than a 320 core at native resolution. Have I missed something?
