I have a pair of Nikon 7x50 binoculars that we carried on the sailboat. they are great binoculars but much to big to carry in the field. the 2 pair of 8x20s that I have had for years do not adjust very well and were only marginal when new. will be using mostly out to 250 yards, checking fields for coyotes, hogs and such, early and late day. looking for suggestions in the $75 to $250 range.
