Hydrophobic coating: keeps snow, water, and fog from making your vision blur.
Anti-reflective (AR) coating: improves the transmittance of light, reduces reflection from lenses, and eliminates stray lights.
Anti-radiation coating: to protect your eyes from radiation. UV coating: to protect your eyes from UV radiation. Hard coating: to prevent heavy scratches from occurring on the surface of the lens.
Photochromic coating: to make lens darken on exposure to specific types of light, most commonly ultraviolet (UV) radiation.
Easy to Focus
Corrective optical coating is good for color fidelity and minimize distortion. Diopter System adjusting the imbalance vision of both eyes. The smooth and large center focus knob makes it simple to operate and easy to focus.
Large focus knobs make for easy and precise focusing, and twist-up eyecups allow for quick adjustment of eye relief to obtain a full field of view. Eyecups can be easily positioned for use with or without eyeglasses
Bak 4 Prism
Bak4 is a glass designation used by Schott AG, an old and respected German manufacturer of optical glass. BaK stands for BaritleichKron (German for "Barium Crown"). It is used for prisms in most (but not all!) high-end binoculars. It has a higher refractive index than BK7 glass (another Schott designation). This means that, if it is used under the conditions that exist in most common binoculars ("fast" objectives, low magnification) more light from the periphery of the field of view will pass through the prisms to the eyepieces; the edge of field will be brighter, but there will be no effect on the middle of the field. It is therefore deemed desirable, and BK7 has acquired an undeserved reputation for being "cheap": in fact, it is better than BaK4 for some applications (which is why it is used in some of the very best binoviewers). I had to take the BK7 photograph to the right from slightly above in order to make the grey "cutoffs" clearly visible at the bottom of the exit pupil.
Quick alignment, compatible with phone case, portable and stable. Suitable for most smart mobile phone models.
Water resistance/ Fog-proof
IP67 Water resistance, Fog-proof, designed to inhibit internal fogging, fit for daily use, and most outdoor environment, offering an excellent user experience.
We have a fun trip on Saturday, its was beautiful day to go kayaking. I brought this binoculars with us and my wife love it. I have the model 3 and she has the model 1, both works great. Thanks for bringing amazing products and affordable price to market.
I use these for birding and they're great. They were a bit bigger than I expected - about half the size of regular binoculars. They magnify excellently with great image quality, even in bright light and low light. The cell phone mount is a bit difficult to get used to but it came for free with the set so I'm not arguing. The case and strap are sturdy. I would recommend.
This is my second pair of these. VERY well made and durable, these do not well endure being run over. I have a small luxury sedan, not an SUV, and they look pretty good and still adjust and focus, but one of the lenses inside the right tube was crushed, and, obviously, spending two or three bills to repair $45 binocs would be ridiculous, so I ordered another.
As with the first, these were perfect out of the box and are marvelous binocs for an unbelievable price. The optical quality is positively CREEPY good, and they are lightweight worn around the neck and adjust and focus smoothly.
Being 12x, they are sometimes hard to hold still, but the image is incredible and the field of view is wide enough to be very useful. They accommodate a tripod mount adapter, this found by unscrewing the knurled nut between the objective lenses.
The cell phone gadget works only fairly well with my Moto X, and I see only a circular, but sharp, image in the center of the phone. Given that, it DOES work and you might find it useful. With phones being made ever bigger and thinner, the adapter might not accept yours. I suggest you not consider this an important reason for buying these.
I was looking for a inexpensive pare of binoculars, that I could throw in the truck and not have to worry about. They meet the bill perfectly. I am very impressed with the clarity. In my opinion well worth the money.
Captured some wildlife animal yesterday, great image. I dropped it under water but it still work well.
Image is very very sharp, I start to love my new binoculars, this model 1 has the phone adaptor to take picture as well.
Haven't try it yet but the box looks clean and very professional! Got it in 3 days, great service!
Not heavy, good quality for a price. I took off one star because attachment for cell phone works for one lens only. And got broken on same day. So I have to glue it. Not a big issue but still it was a new item. Still recommend . But don't compare it with professional binoculars prices over $150
These binoculars are well built and provide a perfectly clear view of whatever you look at. This pair was the lowest price 12x42 binoculars I could find and they do a great job I don't know why you'd need to spend more on a similar pair. Comes with a neck strap, lens covers, and carrying case so you have everything you need. Great deal.
