Infiray Outdoor along with IrayUSA have set the bar yet again with the world's very first true high definition thermal weapon sight. Never before have we been able to see in the dark THIS clearly. Never before have we been able to detect THIS far! There have been many advancements in thermal technology over the past decade and this is no doubt the biggest leap in thermal sensors we've seen in years. Night hunting with thermal has just been advanced well beyond what we ever dreamed!
