FMC & Bak4 Prism: The multi-layer coated optical system reduces glare and ghosting, and the high light transmittance provides a brighter, clearer view. The high-refractive index BAK4 prism ensures excellent light transmission and minimizes chromatic aberration, providing excellent brightness, resolution, and edge definition.
IPX7 Waterproof Construction: The SV47 binoculars are waterproof and can withstand sudden rain or water splashes. The nitrogen gas filling prevents fogging and mold from forming inside. They offer a long service life and can be used in harsh environments.
Large-diameter lens: The 21mm eyepiece makes observations comfortable and reduces fatigue. Superior optical performance delivers clear, sharp images. The 42mm large-diameter objective lens provides better light-gathering performance and a wider field of view, making it easier to see and capture your target.

If your left and right eyes have the same diopter, you can set the diopter scale on the eyepiece to 0 and turn the central diopter adjustment ring to focus, allowing you to see the image clearly with both eyes. However, most people have different diopters. (1) Choose a target, such as letters on a sign. (2) Look through the left eyepiece with your left eye only and turn the central diopter adjustment ring to focus on the target. (3) Look through the right eyepiece with your right eye only and turn the focusing ring on the right eyepiece to focus on the target. (4) This will adjust the difference between your left and right eyes and eliminate any misalignment between your eyes. Then, simply turn the central focusing ring to focus both eyes simultaneously. ◆By following the above steps, you will be able to focus both eyes and enjoy clear, crisp vision. (If you adjust it incorrectly, the field of view may become blurred, so be sure to follow the adjustment instructions carefully.) Generally, the larger the effective diameter of the objective lens, the better the performance, but the binoculars themselves will be large and heavy, so choose a size that suits your purpose. For concerts, theater, outdoor sports, etc. with a magnification of 4 to 8 times, the effective diameter of the objective lens should be in the 10 to 20 mm range. Birdwatching
For binoculars with a magnification of 7-10x, the effective diameter of the objective lens is in the 20-40mm range. For watching baseball, soccer, and other sports at stadiums with a magnification of 7-8x, the effective diameter of the objective lens is in the 20-30mm range. For marine sports with a magnification of 7x or more, the effective diameter of the objective lens is 20x or more. For leisure activities such as traveling, hiking, and driving with a magnification of 7-8x, the effective diameter of the objective lens is 20-30mm. For astronomical observations with a magnification of 7x, the effective diameter of the objective lens is 50mm or more. Don't worry, a binocular with a large exit pupil won't be too bright to use in bright conditions. Conversely, a small exit pupil will be too dark to see in dark conditions, so be careful. This refers to the distance from your eye to the eyepiece that allows you to see the entire field of view when looking through binoculars. The longer the eye relief, the easier it is to see, even with glasses. Binoculars with a long eye relief are generally called "high-eye binoculars." If you wear glasses, an eye relief of 10-15mm is recommended.
