Calculated from the sensor's pixel pitch and the lens focal length, for clear air.

Nocpix quotes 2,610 m, 2.5× our figure, because makers usually measure against a person’s full height rather than their width. Why the numbers differ

Smooth 60 Hz picture on a running animal
Built-in laser rangefinder
Swappable battery pack, so a spare doubles the run time
Light at 24.7 oz, 3rd-lightest of the 22 binoculars here
