I don't know if they are still available. I have a 4 power with adjustable objective and a 30 mm tube that is bright and clear, but made for someone with longer arms than mine. I can't get it far enough away for a good sight picture. If I set it on the bench and move back a little further it is pretty good. Just not for me and shooting.
Mine is old enough to be a Japanese product, not Chinese like the current models are. I expect the Pro class disappeared with the change of ownership.
