    Ultravid HD+ - Any changes in the overdrive past infinity?

    Thanks Jessie. You are correct. I didn't read the Op carefully enough.

    Ultravid HD+ - Any changes in the overdrive past infinity?

    etc I'm not an expert but the markings on the diopter scale on my 7x42 HD+ only go to 4. It can be adjusted slightly beyond the markings but my guess would be only to @ 4.5 or so. Mike
