Hi All,
Some interesting replies here and good advice.
From my perspective I shoot with both thermal and NV. The NV is only when I have to for work. For shooting I would always choose thermal, without hesitation, but my frame of reference is different to most I would expect.
My reasoning is that the scope I use (T-Ceptor PRO 55) gives me as good an image as any NV out to 200 yards for putting bullets in the right place, and beyond 200 yards it gives a better image due to the vastly higher contrast. The other big plus is that it's all self contained, very light and compact with no illuminator, etc. to faff about with. It also allows me to shoot in conditions when you would be going home with NV, a lamp or even a different thermal scope. It will also allow me to shoot foxes that just wouldn't be able to be seen with a lamp or NV, even in perfect conditions. It's just much more efficient and absolutely top of the pile.
All that said, and NV setup on the rifle will be a lot cheaper and do the job fine most of the time when weather is playing ball and the foxes are out in the open.
A good spotter is a must though and a great starting point. Don't get the cheapest, unless you want to be verifying every 'blob' you see with the rifle. It will soon get boring and tiring. Also you don't need the most expensive either. At the other end of the scale the lenses get bigger and the units heavier and more cumbersome (and some of these units won't perform as well as cheaper ones).
For a spotter a budget of £1500-£2000 will get you something plenty usable. If you can push it out to £2500 you can get something pretty much 'ideal'...in my opinion.
What sort of shooting is it for? What are your ranges and expectations?
Cheers
Clive
