They use two electro magnetic sensors, measuring the interruption of the EM fields by the metallic bullet. That's why they are unaffected by environmentals.
I used mine for the first time the time the other day. I've never used a chronograph before, it was certainly as easy to use and reliable as advertised. As for the POI change I couldn't really answer, in my case as the rifle is new to me and not a tack driver. I'm accepting that if need be, I'll run speeds separate from any groups. I don't really shoot any groups anyway.

I did have to send the first one back as the LED display was buggered on arrival. Also, I hadn't considered the erosion on the bayonet from the muzzle blast. The wear from a single session wasn't out of this world, but hopefully was part of the design consideration.
