Hunting rangefinders with reticle illumination

Reticle illumination

— the presence in the rangefinder of a special illumination for the aiming mark, which is usually either a light mark on the lens or a set of pixels on the screen. For traditional optics, this feature is far from mandatory and is intended mainly for specific cases - for example, when a dark target is against a dark background, which is why the unilluminated reticle becomes almost invisible. It is worth considering that the backlight usually requires a battery to operate. There are also systems that do not require power (tritium backlight), but they are practically never found in civilian models of rangefinders.
