I bought the 1300 Dec. 2018. It was discontinued shortly there after. just my luck. For that matter, bought the Razor HD binos towards the first of the year and shortly thereafter, they came out with the UHD. (how my luck runs).
back to the rangefinders... Should it be normal for them to come up with a "blank" when you try to range something (ok maybe it was too far or not reflective enough) but then won't range anything. Even a huge tree at 40 yards. If I let it turn off and try again, it will eventually work again. But may have to do that several times.
I could see this being a problem when trying to range a hunting situation.
