Quick question. I bought one of these summer of 2009 and it seemed to work fine. Just took it out on a hunt last week and it ranges about 10% off from what my buddys brand new Leica 1200 ranges. 20yrds at 200, 50 at 500 and so on. Considering it was $400 and been used twice I'm a little disturbed. I wonder which one is correct??? If mine is bad it is wayyy out of warranty. Kinda upsetting.
