Didn't know whether to post this here or in cameras section. I ran into a glitch with the PARD 007 night vision attachment that goes on the end of your existing scope to yield night vision capabilities. Works quite well EXCEPT if your vision is compromised , say , needing reading glasses. As I became older , my vision started sucking more and more. currently I use a + 175 - +2 set of reading glasses. OK , why does that matter? Glad you asked , If you focus your scope for regular day shooting , most do it without wearing reading glasses. Problem is , the PARD's camera adjustment is limited in it's focusing range and can not accommodate that much vision distortion. How to remedy the situation? Wear your reading glasses to focus your scope , when done , connect your PARD and THEN fine focus the lens for a clear , sharp image without needing your glasses to see display . Little bit of a pain , but worth it in the end.
