About this product
[Magnification 8x] It looks like the size of an object 80m away when viewed from a distance of 10m.
[Foldable, compact, high-performance machine] The lens aperture is large, and the brightness and visibility are one rank higher. Since it is compact when stored, it can be easily carried.
[Active in a wide range of scenes] You can play an active part in various scenes such as concerts, live performances, watching sports, watching plays, traveling, and athletic meet.
[Equipped with specifications equivalent to high-end machines] Full multi-coating, transmittance increase coating, waterproofing, nitrogen gas filling, long eye relief, rubber coat.
[What is full multi-coating?] A coating that increases light transmittance and suppresses flare and ghosts is applied to all lens surfaces and the light entry surface of the prism.
[What is transmittance increase coating] The latest film formation technology dramatically improves the transmittance in the visible light region.
[Reliable even in bad weather] Waterproof performance equivalent to JIS protection class 6 is safe even in bad weather, and nitrogen gas filling prevents fogging inside the lens due to temperature difference.
[Long eye relief] It is a model with an eye relief of 20 mm or more that is very easy to see. You won't get tired even if you look into it for a long time, and you can use it without eclipse even while wearing glasses.

What are binoculars?
Binoculars don't just make distant objects look bigger. Since the light is collected by a large lens, you can observe more stars and pale nebulae than you can see with the naked eye when you look into the night sky, and even fine details when you point it at wild birds and flowers.
Another major feature is the three-dimensional effect. With the "floating" effect of seeing with both eyes, you can see distant objects such as performers on the stage in three dimensions with a sense of realism.
How much magnification is good?
The "magnification" is the ratio of the size when viewed with the naked eye to the size when viewed through binoculars.
With 8x binoculars, it's the same as watching a stage 80m away at a concert from a distance of 10m. With 10x binoculars, the distance is 8m, which makes it look a little bigger and more powerful, but the field of view is a little narrower.
Generally, it is easy to see up to about 10 times even if you hold it in your hand, but we recommend using a tripod for higher magnifications.
Difference in objective lens diameter
The larger the lens that receives light, the higher the brightness and resolution. Binoculars with a large objective lens are recommended for use in dimly lit scenes such as live venues with dimmed lights and evening and night observations.
However, be aware that the aircraft will be larger and heavier.
The AD 8x25 (8x) and AD10x25 (10x) with an objective lens diameter of 25mm have an excellent balance between visibility and the size of the aircraft.
Effect of full multi-coating
It is said that the biggest difference between binoculars is the coating, and there is a big difference in brightness and sharpness of vision.
Light is lost little by little each time it passes through the surface of the lens or prism of binoculars, and the amount of light is insufficient and it becomes dark, or it is reflected excessively and leads to troubles such as flare and ghost.
"Multi-coating" prevents this, increases the light transmittance, and suppresses flare and ghosts.
In addition, full multi-coating is applied to all lenses and prism surfaces.
Equipped with new coating
[Transmittance up coating]
The latest film formation technology dramatically improves the transmittance in the visible light region.
[Phase coating]
It improves the resolution and contrast by correcting the phase difference of light.
[Reflective coating]
It is applied to the aluminum reflective surface of the prism to reduce light loss.
Waterproof & filled with nitrogen gas
【waterproof】
Safe even in bad weather. It has waterproof performance equivalent to JIS protection class 6 so that water does not enter inside even if it receives a direct jet of water from any direction.
[Nitrogen gas filled]
Prevents fogging inside the lens due to temperature differences such as sudden cooling in the morning and evening.
Compactly folded and stored
It can be easily folded and stored compactly. You can easily carry it for everyday use on trips and holidays.
Easy 3 steps How to use binoculars
[① Adjust the length of the target]
If you want to use it with your glasses on → Short
Naked eye, long eyelashes, etc. → Long
* The binoculars in the photo are slide type.
[② Let's match the eye width]
The best position is the position that becomes a "one circle" while looking into it.
[③ Let's focus]
① Look only with your left eye and turn the focus ring to adjust.
② Look only with your right eye and turn the diopter adjustment ring until you can clearly see the object.
