This is my first night vision optics ever.
I carefully researched the market for 1 month, and from all Gen1 types this was The One that seemed to offer the most out on the field.
And it was the right choice!
My first impression: "damn this thing is real!!"
Second impression: "damn I can see way farther than what I learned it is capable of!!"
At night if ambient light permits bare eye visibility to roughly at 50m, then in these conditions with the Opmod Vega in passive mode you can see very clearly and very detailed to vast distances. (So again: with bare eyes in low ambiental light 50m means long distances in passive night vision mode.)
With infra ON the light emitted is not really far, I can say less than 50m, but specs mention this. It's a short range flood type of infra red light. Get a long range one optionally if you need a long range infra. (The "red lighting LED" infra can be seen shining on the front of the device, but only for like 20m.)
Warning! From the moment the device is turned OFF, the night vision is still ON for a few minutes (it's slowly fading out!) so bare in mind that this way you can still see for like a good 10 minutes, also be very careful not to flash any lights into the front objective lens, as the device is still in fragile mode. Put on the rubber cap when you turn it off.
The head-mount is tricky to figure out how to use it in the dark (mounting on and getting off the scope), but once that I got used to it, it becomes easy. (Advice:...
