Waterproof binoculars have a trick up their sleeves: thanks to the tight structure, they are also dustproof, and they won't develop a layer of dirt on the inside. Thanks to the apparent field of view, these binoculars are easy to use: lifting them up, you won't spend time finding the right position, as the image is large and clear. The tripod adapter allows you to use a tripod or monopod, or for making a finnstick that uses a tripod type screw. Thanks to the twilight factor of 20.5, you won't be stranded even in relatively low light situations. - Waterproof, gas filled, fog free - Fold-down eye cups make for easy use even with spectacles - Rubber armored - Large focus wheel for easy and precise operation - Schmidt prisms - Magnification: 10 x - Exit lens size: 42 mm - Pupil size: 4.2 mm - Field of view: 6° - Field of view at 1000 meters: 105 m - Apparent field of view: 60º - Twilight factor: 20.5 - Eye relief: 15.5 mm - Diopter adjustment +/- 4 - Pupil distance 58.5-72 mm - Closes
