What do I.R. , night vision binoculars do?
Hi all, I purchased a pair of binoculars last week. They have red coloured lenses and they state that they are I.R. and night vision.
I have tried viewing through them at night but they don’t seem to be any different to any others. Can anybody explain what these terms mean?
Tanx for reading.
if they are nightvision you will know, the image will be green and you will be able to see clearly in very low light, they will also have a power source such as battery or need charging and they will have ofcourse an on/off switch.
nightvision binoculars are very expensive probably around £300 for the cheapest and £2 – 3 grand for decent ones,
so if you bought them cheap youve been had. if you paid a lot then shouldn't you know what you are buying already before you spend this kind of money?
Hot design and superior optics of these binoculares make them a must-get companion for outdoors nature observing, hunting, camping, fishing and sports or concert viewing. Allthough these binoculars are marked as “Night Vision”, they are not real military grade $2000
