The MeoStar B1.1 10x42 HD/ED binoculars have a slightly new name because Meopta updated the diopter control to a locking design. They still have extra-wide dispersion, but the fluoride objective elements eliminate chromatic aberration (CA) or color fringing in difficult lighting conditions and deliver pin-point resolution, increased contrast, and vivid color fidelity. Their wide FOV and extremely flat field of view allow you to capture more images and effortlessly pan distortion-free. The MB5501 ion-assisted lens multi-coatings deliver maximum brightness in all conditions with pin-point resolution and crystal-clear edge-to-edge performance. An ergonomically shaped armor design with sculpted thumb pockets encourages a balanced, secure hold for comfort during extended glassing sessions. All Meopta binoculars carry their North American transferable lifetime warranty.
