I currently use a Swaro STS 65 HD, but am looking for something with a larger objective. I have read great things about the Kowa TSN-88 Prominar which I understand is the only spotter to have pure fluorite glass. Anyone out there have one of these? Is the clarity as good as everything I have read suggests it is? How do these scopes compare with the Swarovski HD series? Are they built to handle some abuse? Any negative aspects to this scope? Thanks in advance for any replies.
