yes yes, maybe I can already imagine the motivation ... in fact ... mine was an almost rhetorical consideration and represented more of my thought than a real question ... Surely your Bering Optics Super Yoter 50 and mine Infiray Saim SCH50 with 3X minimum magnification are currently among the best thermal riflescopes in the world. To go beyond 3X .... the brand new Infiray Tube TH50 with 3.5X is truly a great device. I was able to test it in front of the shop and was impressed. For those who want more magnification, for long range shots, IMO, right now, is an excellent choice. I have not even considered devices with 384x288 medium definition sensors (such as the Thermion 2 XQ50 or the Trail 2 XQ50 lrf). After various tests here in the fog and in the high relative humidity of the Po Valley, I assure you dear friends, that the 384x288 loses a lot of detection capacity. The 640x480 or 640x512 sensor becomes a practically mandatory choice ....
