How much of a difference in picture quality to you see between the Thermion XM38 and the XM 50 in practice? The video you show would suggest quite a clearer picture in the XM 50.
The Thermion was the "XP" which is 640 resolution. It is quite a bit better. The XP50 seems to have just the right amount of zoom for hog hunting. The extra zoom is nice on the XM for single hogs or coyotes, but on groups the XM has way to much zoom to really be effective. The FOV is so narrow, makes it challenging to get on the next hog once they scatter.
