Exactly, more of a historical reference point, with some loading info from that period, Jim Carmichael and bill ruger designed the ruger m77, other chamberings now compared to then and worth having on the shelf imo, you will find x2 copies on eBay, both under a tenner if interestedAnything from 1975 is most definitely no longer modern, it’s approaching 50 years old
Strange to think bohemian rhapsody by queen released in same year, 1975!I wish I was!

Agreed BruceYou just described the difference between resolution and contrast
NV units have (and will always have) higher resolution than thermal.
That's principally down to the wavelength they work at (NV around 1 micron, thermal around 10 microns) which in turn sets limits on how small the sensor pixels can be.
Lots of small pixels will give a more detailed image.
However, because NV is a mono image (everything is a shade of grey) and there is often little between the shade of grey produced by a potential target and it's background when illuminated by IR, the result is that NV is inherently a low contrast technology which can make spotting a target difficult.
Thermal, on the other hand is a low resolution technology. The sensor pixels are much larger and there are many fewer of them in a thermal sensor.
However, thermal images have much higher contrast than NV because the temperature difference between most potential quarry and it's background is enough to make the quarry easily visible.
So, thermal for spotting because it's easier to find a potential target and NV for shooting because NV gives a more detailed image of the target.
That works for many people and I'm not going to knock them for it.
However, in trained hands, top end thermal scopes have for a few years been more than capable of correctly identifying targets out to the maximum range that any sensible, safe shot would be taken.

I know it's a bit of an old thread but still relevant. For a while I've been using my first and only thermal purchase, a Habrock hq35 spotter. What a game changer! Target i.d is normally quite easy but at times, especially if an animal is laying down or walking streight towards you it can still be tricky to know what's what.
The beauty of the Habrock is it has an optical channel but the IR isn't up to longer range stuff, especially as it's not very well aligned.
I tend to use the Alpex 4k for foxing.
I also have the use of a guide tu651 thermal scope though, which a friend has lent me for "longish term" I believe so I'm very lucky! It's pretty decent, but I got put off using it for a while after shooting a 200yd cat that I thought was a fox. It moved just like a fox, came to the call, stopped to the "oil". Distance was due to the terrain, 200yds was as close as I could shoot due to the valley.
But recently I've adopted a plan to keep a small vessel torch in my pocket (that I set the correct beam and taped into position.) if in doubt I'll use that with the Habrock to confirm id but since trying it so far theres been no doubt.
The thermal has allowed me to sort several foxes on a hillside across a valley that I'd of struggled with with the Alpex, I know that because I tried it too. Just down to the type of terrain and brush,/ trees etc, difficult getting on them with the Alpex.
All in all, the thermal I find the ultimate fox tool, but you must have ways and means to be sure of what it is, and be prepared to not shoot if not certain. The cat was my only boo boo, but I have had times before where I've been convinced a fox was in a hedge to find out it was a calf or lamb laying up that strayed out of its correct field etc, confirmed by the Alpex or eventually just walking up and shining a regular torch on it.
Absolutely spot on here. Very easy to tell the difference if you spend more then 1 or 2 seconds looking at the animal. The other assumption I will make is those with thermal scopes more then likely have a thermal spotter. On this basis there is little excuse for even pointing the rifle at something you haven't made a positive identification on. If the animal is in cover then wait for it to come out...and as has been mentioned ... if there is any doubt then dont pull the trigger... end of.When you have used the thermal for a bit longer you will soon be easily able to tell the difference - cats look nothing like foxes and indeed badgers nothing like foxes after a good few outings
This. Double layer protection.Thermal spotter and nv scope for me. It’s easy to miss undergrowth and saplings that may cock up a shot with a thermal
