The new Wyoming-based optics company Maven (mavenbuilt.com) offers a variety of customization options for its B Series of binoculars. The series includes three models: a standard full-size ($900), a full-size with enlarged objective ($1,000), and a compact binocular with midsize performance ($500). Customers can choose from a range of solid colors and camouflage patterns for the casing and accent colors for the focus wheel, ocular and objective-lens rings, and other elements. The casing is made of a non-PVC rubber and has milled aluminum accents. The binoculars also feature extra-low-dispersion glass and lightweight magnesium frames.
