Abstract
An optical device includes a toolless rezero system and/or a zero locking system. The rezero system can operate in a first mode in which a scale ring is non-rotatable relative to an axis. The ring can be manually moved to a second mode, where the ring is rotatable relative to the axis, so alphanumeric characters and bars can be moved about the axis to align a preselected zero element with a reference element and rezero the device. The zero locking system can include a locking cover button that is manually movable to automatically operate a locking ring in a first mode in which it rotatably couples the dial with an adjusting pin to move a reticle, and in a second mode in which it couples the adjustment dial to an immovable wheelbase so the dial is non-rotatable, and the reticle is locked in position. Related methods are provided.
