Depending upon the conditions of the night, I will happily go up to 6x mag on the pre-set settings, using the user setting on low contrast I've taken it upto max mag of 14x and still had the identifiable profile of the fox including tail . Pulsar presets such as forest & ident do tend to be high in contrast as a default which does blur the outline above a certain mag which is why it pays to play with the brightness & contrast depending upon conditions as with most thermals.
I'm not saying I can always ID immediately every time, sometimes you obviously leave the shot or await your opportunity of a firm ID .
I do also now have a C50 on my .243 for occasional fox duty, such as breezy nights & larger permissions.
It's good, but I prefer thermal
I have a similar setup , I use a Thermion 2 xp50 Pro/ LRF currently sat on my .233 and I also have a pulsar C50 sat on a .308 these are sat in Innomounts and can be all swaped about between.22LR /.223/.6.5 cm/.308 in 30 secs and all zeroed with there corresponding profile . It’s just absolutely no hassle at all .
I don’t have issues shooting at 300m with either option
I don’t like high base mags , most of my fox shooting is either right next to or right in the middle of hundreds of sheep/lambs , so I personally would struggle trying to find my target in amongst that lot with the narrow FOV that the higher magnification would give me . Which was one of the many reasons I got rid of my old drone x10 ( but that’s another story )
I’m also a big fan of using decent mounts and a traditional rifle scope design .
But I did shoot for a quite a long time using my first spotter ( axion Key ) and a NV scope for a while but also felt it a little awkward sometimes , anyway when the new Thermion 2 pros came out last month with the LRF dumped on top I knew instantly I was having one , and I love it .
I can sit with my rifle on a tripod and looking / scanning over my sheep . I can identify , accurately range and nail the bugger out to 300m all without taking my cheek off the stock .
I can still shoot in mist / fog / rain /snow / in reduced ranges maybe but situations when NV would just fail.
I don’t have to worry about IR , sometimes I can unsettle the sheep especially when using IR lasers .
Well these are just a couple of reasons I bought what I have , I still very much enjoy shooting with NV and my C50 is just brilliant but I don’t think they can be compared really , there just two very handy tools I’m grateful to have at my disposal.
But ….
I will still and will continue all the while I have a hole in my arse . Shoot with just a rifle , red lamp and hand call whenever I can get away with it .
