How do monoculars, rangefinding binoculars and digital displays differ?
A monocular is used with one eye. Rangefinding binoculars combine a two-eyed view with distance measurement. Two viewing channels do not automatically mean two independent measuring systems, however. The arrangement of transmitter, receiver and optical channels depends on the design.

Magnification, field of view and image quality matter when looking through the instrument. For the display, font size, brightness and contrast also count. An overly bright display can be distracting in darkness; a dim one may be hard to read against a bright background. These characteristics are separate from measurement accuracy.
Weight, controls and battery access also affect use. An instrument with more functions is therefore not superior in every respect. A useful comparison considers observation, measurement and operation separately. This makes it clear whether a new feature improves the actual distance measurement or simply adds another display or connection option.
