I bough this rangefinder last summer I used it on all my fall hunts. It works well in all conditions temps around 90 with heavy thermals and sub zero and it never failed. I want to sale this and put money to range finding binoculars. It has a blemish on the exterior but all internal functions work great and glass is really great quality. Ranges great no problem picking up objects up to 1600 yards in extreme conditions. Looking to get $600 OBO plus shipping.
