Thread: Night vision

I don't have one but do have a pard add on unit the 007a. The 850 and 900 refer to the wavelength of the illuminator. 850 is just in the infra red portion of the spectrum the human eye will see a faint red glow looking directly at it. It's also just on the edge of the spectrum deer and other game can see. 950 is totally invisible.
So far I've had no trouble with the built in illuminator its 850 nm and it's shootable range is 250 metres.
I have had trouble however with depth perception and range estimation as the screen Image seems to lack the depth perception optics have.
I see your looking at dedicated units, during the day the pard has difficulty with highly contrasting light and dark which makes it very hard to use. I just leave it off till evening than attach it. A dedicated nv scope might have better contrast control for daytime use.
