The 10x42 VIV-AV-1042 Aqua Binocular features a waterproof design, and is built around BAK 4 roof prisms. A magnification power of 10x coupled with 42mm objective lenses makes the binocular suitable for birdwatching, sports events as well as concerts.
The eyecups of the Aqua Binocular can be twisted up so that eyeglass/sunglass wearers can comfortably look through the binocular without taking off their glasses. The diopter adjustment feature offers visual correction for an optimal view. A central wheel focus design with a large focusing knob ensures that even users wearing gloves can easily adjust the focus mechanism.
Multicoated high-definition lenses of the binocular help reduce glare, ensuring clear image reproduction. The binocular features 6.3º angular field-of-view and 330' (100.5m) linear field-of-view @ 1000 yard (914.4m).
