Abstract
A selectable fixed-focus binocular that is highly functional and simple to operate for the end consumers. The binocular combines the close and fine focusing advantages of a traditional binocular with the ease of use offered in a fixed-focus or focus-free style unit to make a versatile, user-selectable focus style binocular. The end-user can use the binocular in a typical, manual focus mode or manipulate the control knob to transition for use as a simple, fixed-focus unit.
