I have a Leica 1000 that I have been using for a few years coyote hunting and I do most of my coyote hunting during winter and longish ( 200 to 700 yards) ranges. Well the leica 1000 doesn't cut it when ranging coyotes at long range when they are in fields or on hillsides that are covered in snow. Anyone have any experience with the leica 2800 or 3500 coyote hunting in winter? I was thinking on buying a Terrapin X but read some bad reviews regarding customer service and warranty.
