Some years ago, outdoor company Maven of Lander, Wyoming started a new optics business: custom made binoculars and scopes. Selling directly to the customer, and using well designed, Japan-made optics, Maven offers binoculars tailored to your wishes. They currently come in many sizes, among which 6×30, 8×30, 10×30,  8×42, 10×42, 7×45, 9×45, 11×45, 10×56, 12×56, and 15×56. After choosing the optical configuration (magnification, objective diameter) and the frame size, the customer can select from a choice of body armours, focus wheels, a number of decorative elements and colors, and even individual labeling and engraving. The mechanical and optical quality of the Maven binoculars is high, the prices thanks to direct sale are very competitive. Complemented by an „unconditional life-time warranty”, Maven’s binoculars offer very good value.
