The Discovery was Steiner’s top binocular for nature observation until it was succeeded in 2014 by the same size “Wildlife XP” (see separate post). It would compete in the upper class with binoculars such as the Meopta Meostar 8×42 (see separate post), Minox APO HG 8×43 (see separate post), the Nikon HG-L 8×42 (see separate post) or the Leica Trinovid 8×42 (see separate post). The Discovery used to be one of the most expensive instruments in its class, it offered excellent mechanical and good optical performance.
