The Steiner Observer 20×80, whichs looks and feels like a military instrument, plays a bit the role of “costly outsider” within the 20×80 market, but its narrow FOV aside, it is very well built, has sturdy mechanics and very decent optics. See further information about it in the link below under “Review”.
