SVBONY SA203 12x50 Binocular with IPX7 Waterproof and Bak-4 Prism

 With highly quality PPS plastic materials, this roof binocular provides an excellent optics image with a 50mm objective lens diameter associated with 12 magnifications. You will obtain a more expansive and comfortable FOV by a 21mm eyepiece diameter, giving you an impulse to take it outdoor.  
2. IPX7 waterproof permits you to use it in the most extreme weather conditions. Smooth central non-slip focus knob allows you quick focus, which is easy to operate even for beginners. What a humanized design!
3. BAK4 prism, a fully multi-coated optical lens, allows more light transmission, bringing a stunning image.
4. Twist-up eyecups and long eye pupils provide an easy way to find a comfortable observation distance no matter whether or not you wear glasses.
5. With the army green clothes, you may spot stars twinkling in the sky, the thrush frolicking on the branches, the athletes setting a blistering pace on the playground, the prey at a distance, etc.
