My shooting buddy bought one a few weeks back and we've all had a go with the unit and side by side next to my axion2 and hellion at base mag you cant really tell the difference.
Absolutley perfect for a spotter and at £399 you couldn't by a entry level (used) spotter at that price point
if I didn't already have a spotter I would not hesitate to buy one for myself

I don’t know what gear you are currently using or how much it costs, but calling 384×288 “very low resolution” is unreasonable.
A typical thermal sensor resolution scale would be something like: 160x120, 256×192, 320×240, 384×288, 640×512, 1280×960 and above. So the question is: which resolution would you call “normal”, and how much does that level of equipment cost?
Regarding the “Hmm” video, surely the author could provide side-by-side comparison footage from the NordForce and from his other thermals that are not “Hmm”. It would also be helpful if he could state what those other thermals are and how much they cost, so viewers can make a fair comparison.

For a spotter where you just look for a heat source to Further explore with better optics, 384 isn’t ‘very low’. It’s on the bottom half by today’s standards, 160 and 256 are the ‘very low, 320 and 384 yeah, maybe ‘low’ 640 medium high and now 1280 is seen as the high.
It’s all in application and expectations as with all things in life. I wouldn’t shoot a CF for foxes with anything sub 640, the clarity fkr shot placement, animal positioning, etc just isn’t there to make it ethical. For rats and rabbits with a RF or AR, say, sub 50yds on base mag, 384 is probably a great little scope if on a budget.
Good value for money, relative to application and not expecting it to be good for nailing foxes at 470yds.

Same just placed an order!
Reading the earlier posts around what the scope might withstand as to recoil values, (.308), Would it be asking a bit much to take a calculated 3,772 Joules?
wouldnt stop me, my unit seems quite robust.Reading the earlier posts around what the scope might withstand as to recoil values, (.308), Would it be asking a bit much to take a calculated 3,772 Joules?
I can agree the 'very' low was a bit harsh, sorry I'm slightly dyslexic. but I can't read the warning texts that pop up even if I get much closer to the screen of my Galaxy A15 5G mobile via hotspot, its great on the viewing screen. It's confined to portrait mode because the resolution isn't enough to allow it to expand or rotate to landscape view with auto rotate enabled. I can't read the notifications that pop up on it. It's still a massive bargain 'finder' to locate 300 yards rabbits at £399 posted with 3 years warranty.
I have no problem with mine viewing it on a Samsung Tab, also set to auto rotate can clearly read the message when it's going to do a calibration.
@Dave-G Thank you for explaining. I understand that by “very low resolution” you were referring to the mobile app capability, rather than the scope itself.
The best way to record video will be directly through the scope, then download the video files to a laptop using the supplied cable.
I'm interested to find out what is the top recoil rating for the unit, not sure how to equate the given G measurement to anything.
A "6000 joule" recoil rating is an industry standard for heavy-caliber shock resistance, most commonly found in premium night vision and thermal optics. It ensures the device can withstand the recoil impulse of massive cartridges like the .375 H&H, 9.3x64, and 12-gauge slug guns.I'm interested to find out what is the top recoil rating for the unit, not sure how to equate the given G measurement to anything.

I don't post this much here because in the UK there's not a lot of Gen3 and not a lot of use of larger calibers.
G/s around 300 or less = Usually OK. 400 = precautions as above. 500+ = DO NOT USE without recoil mitigating housing.
It's not an absolute list - just a guideline to help with NV selection Vs Cartridge selection. It's based on a 4Kg rifle ( US AR15 ) so take that into account also. Only fixed rifle weight counts. But it helps put peak recoil in perspective.

So the original info given should have read ... J not g.
Some people were asking about recoil rating and suitable calibers.
These units were TESTED to withstand up to 600g acceleration.
This means they will hold on a rifle of any practical caliber.
They work fine on .308, springer air guns, and anything in between.
You'd have to be more careful with .500 Nitro Express, but we don't think many people would be using it with .500NE.
EDIT: Be careful with eye relief on larger calibers, because all thermal and digital scopes have shorter eye relief than conventional optics.
Yes, thanks, I was amiss at that. The video I posted was from the scope itself. Incidentally, I think you may have asked how I got on with the roof mounting/wifi?
I've tried ready made pivot ball mounts in the past and found they are not very pan and tilt capable, I modified a couple with better custom made stainless pivot ball studs I had made for me and used the pivot ball carrier from a suction mount device from ebay. The hotspot to mobile use drags the 3.7v lithium batteries down to something like 90 minutes, the hotspot presumably/understanably takes a lot out of it. I have a power bank that I have yet to try with it.

This is how I have my setup Dave, power bank last for a very long time. And the base runs off 1x18650 which I have plenty of and remote is two AAA rechargeable.

This may be obvious so please dont be offended but I just wanted to check you have found how to focus the image properly whilst looking through the unit? There is a front and rear focusing twist rings. I dont know if this will help make your image clearer when looking through a phone screen.
Just seen your previous video and it looks like you have found how to focus it. One thing I would mention is I have used several thermal units over the last decade and they all suffer with poor resolution when you zoom in. It appears this is the limit of what they are capable of and I think this Nordforce unit is well above its performance for value. In field use I shoot most stuff on lowest magnification to get best resolution
