The Delta Optical Voyager II 10x50 WA Binoculars are an ideal choice for those seeking high-quality optical performance at a low price. Despite their low price, they are mechanically and optically refined. They feature smooth focusing and interpupillary distance adjustment. Comfortably contoured eyecups and a handle allow for long-lasting, comfortable observations. Thanks to their Porro optical design and BK7 glass lenses and prisms, Voyager II binoculars deliver bright, sharp images with natural colors. The optics are housed in a lightweight, rubber-coated housing that prevents slippage. The Voyager II Series Binoculars are available in a variety of magnifications, each equipped with a universal 50mm objective lens diameter. For everyday observations, as well as for tourist and astronomical observations, we recommend the Voyager II 10x50 or 12x50 models with the lowest magnifications. They provide a wide field of view and a bright image, even at dusk or dawn. The Voyager II 16x50 and 20x50 models, on the other hand, are aimed at users who need high magnification. They enable observations of the most distant objects and can be used, for example, for observing airplanes at cruising altitudes or wildlife. Due to the lower surface brightness of the image, these models are better suited for daytime observations than twilight observations.
