Went out local there and it's so simple to use, very still night and called couple of fox right in. Could see out to 200 yards no problem bit further than that was hard to make out anything out very clear, paired up with a better illuminator i reckon it the clarity further out will be excellent. I've not got extra lenses in and focuses no problem for me. My only gripe is the rubber eyecup falls off so easily. Bit of insulation tape will sort that out tho.
