Bushnell Sport 600 "Bone Collector" Rangefinder.... Anyone own one of these ? My Nikon Pro-Staff started having issues, so, I bought 2 new rangefinders, the same day. One for myself and one for my bro, same models. BOTH have the same issues. They are less than 2 months old and one has only been afield ONE time. They dont read in the snow. Dont read in the cold. Dont read in anything even resembling a low-light condition. I've tried fresh batteries, asked Buddha, rubbed a Genie, did a dance...I can't get these pieces of crap to work for anything. Like I said, it's not 1 but BOTH. Anyone have similar issues ?
