I have a Rev 5. X50 that I always thought was pretty good for detecting laser, at least for the informal tests I had done on it.
Just recently, I got a new RX65 (rev 6.3), and in comparison testing it walks all over the X50 rev 5 in terms of laser sensitivity. In fact, it is almost as sensitive as my V1. This surprised me, because I've always read on here (from GOL and other tests) that the X50 was always better than RX65 for laser.
So I'm wondering if Belscort dramatically improved the laser sensitivity on the new rev (M4 serial number) units. Has anyone with a newer X50 noticed increased laser sensitivity over older units?
