Thread: Night vision 850nm vs 940nm

Hi guys,
looking for some experience with night vision scopes.
i cant afford a decent thermal scope so looking to get a night vision scope to get me going for now.

currently looking at options for the Sytong HT- 70 which comes in a 850 wavelength,
or the pulsar N455 or similar which has a 940 wavelength.

the feedback i have had is very mixed,

1 opinion: 850 is very clear and much nicer to use, can identify and shoot out to 400-500m depending on surroundings, wouldn't even touch a 940, too blurry.
2nd opinion: 850 spooks the animals, the IR lights deer up and they start moving and getting alert when the scope is directed at them compared to 940. the whole point of night vision is giving time to stalk deer and all the time you want to get a good shot, not rush it otherwise might as well use a red spotlight

keen to get some feedback from people who have used these on deer hunting.
940 seems better to not spook the animals but is it really that blurry compared to 850? will it limit the ability to even identify targets?

is 850 IR not actually that bad at alerting animals?

this isn't for rabbits and small pests, its for deer hunting so want to shoot as far out as I can

let me know what you all think so i can decide which one is best for me.

thanks
