I can see climbers on Mt Wrightson (southern AZ) from over 16 miles away. Watching Condors at the Grand Canyon when others with binos could only see specks. Can see Golden Eagle nest from 1.5 miles. Heavy but get a collapsible staff and screw it into the bottom of the binos and can use for hours w/o fatigue. You want the best get these. You will not be disappointed.
Pros: Extream magnification
Cons: Heavy but get the collapsible staff.
