In the EU Photonis make the best intensifier tubes (that others then build systems around), but for low light performance the best US filmless tubes beat them. I have a friend who has compared a number of the highest spec tubes he could find. The military are just after lots of good enough tubes rather than just the best of the best tubes where the manufacturing yield would be very small and costs very high. I note “onyx” being mentioned, which is one of the photonis intensifier models. Twin tube bino gives much nicer views than from a single tube as the brain can average the sparkly noise from the 2 images. Good intensifiers (anything made in the last decade or two) will turn night into day as long as there is a little bit of light, but cloudy skies and deep tree cover doesn’t hinder them much. When it gets real dark well away from towns then the latest and highest spec will begin to pull away.
Thermal is where the developments are (long, medium, short wave etc, zoom, greater pixel counts) as shown by the long distance gps enabled device. Having a fusion of intensifier and thermal is also potent as the end of the video shows.
High spec photonis kit is available, it just costs rather a lot (export controlled of course). Russian stuff is pretty much equal to the EU (from what I understand). Also the west is a good source of NV kit…. How much did we leave behind when we withdrew from the Middle East?!
US hunters seem to have mostly moved across to thermal as it might and day blows intensifiers away as far as spotting warm things at night from long distances.
