Bought it for my b-day, but I had to leave before it arrived. Had a family member try it out. Said you can see the hill about (250/300) yards away. I was surprised. I finally got my hands on it when it was pitch black after rain. I could see maybe 75/100 yards across field and image was blurred due to condensation on eye piece lense. Whipped it off, was better. So I came in the house to check moon phases, last night was 99% full but we still had clouds blocking the moon shine. So a dull lumination. I tried it again. It was vivid, you can make out objects well at distance, by the hill. IR is a nice aid, but seems to be best for super low light. I cant imagine a full moon night, would be like daylight thru it. Says you can use 308 or less. I guess. This isnt like military generation where you can see half way across the county in pitch black. You get what you pay for. First gen works but it isnt the best, BUT it is affordable. From what I can tell dont buy a cheap 1st gen scope, spend the extra $200. Otherwise it looks solid and a good product. One thing i noticed was you can turn the switch off and it appears to continue using captured light without a power source. It dims slowly, saves on batteries BUT it's also why you dont look at light with the lens still green. These things have lotsa dos and don'ts. READ THE BOOK and look up how night vision works to get the most out of your product and how not to break it.
Pros: AA batteries, simple, ergonomic, warranty, doesnt make noise.
Cons: 2nd, 3rd, 4th gen and thermal cost too much.
