[QUOTE="Surveyor, post: 1654050, member: 50720"] Steve, Just got in the USAF cards. Not as many smudges on new cards as old but not as good as the older cards either. The weight of the card is about half to older ones and group 3 is pretty much unusable. May use element one. The Ronchi ruling looks better and more consistent and there is less printing artifacts in the USAF portion, but definitely not good to Group 3 element 6. At 10 meters, it will cover most binos from 3 arc seconds to 10 seconds with group 1 or 2, but spotters or anything in the range of 1.5” to 3” will have to be placed further out. I am at work, so no way to image card very well, so I just handheld a camera to magnifier for the attached images. Best Ron EDIT: Steve, these may be to specs. I just noticed this as part of the description [B][I]"Group 0, Element 1 to Group 3, Element 1; Ronchi Ruling Pattern 1 line/mm."[/I][/B] The spec table says Group 3, Element 6 though. [/QUOTE]
