Which binocular should I choose?
I wanna buy a zoom binocular. I've selected some.
1. Barska Gladiator 20-140x80, Zoom Model#: AB11184

2. Celestron Skymaster 25-125x80

Barska has no fog-proofing, but Celestron has. But Barska is pricier. In other cases, specs are almost the same.
So, what should I buy?
Does non fog-proof binos have a tendency to fog up inside?
You don't state what they are goign to be used for but I would be hesitant to recommend either of them. If you think that by getting high-powered binos you are getting something for nothing because they do the same thing as a telescope forget it - even on an average bino mount this will be useless at 100+. If you plan on using them on a camera tripod forget the whole idea now.
Since you post in the astronomy area we will assume that is what you want them for. The key thing is aperture - 80mm in this case, and _low_ power - I would be hesitant of binos over 30 power even with a binos mount. At the kind of money you are looking at fixed magnification is the way to go - zoom binoculars tend to be poor until you start talking about four figure price tags. Use a telescope for high powered views. A telescope is designed from the ground up to work at high power, rather than having it tacked on so that it looks impressive in a listing, even if it is ultimately useless.

SO)CELESTRON ULTIMA 80 45 DEGREE Celestron’s popular Ultima 80mm Zoom Spotting Scope offers images that are noticeably brighter and sharper than entry level 60mm spotters. The Ultima 80 is a refractor style spotting scope with an Achromatic objective lens. Excellent light transmission is assured by multi-layer anti-reflection coatings on the objective lens as well as on the zoom eyepiece and the BAK-4 prisms. The multi-coated 80mm objective lens delivers 77% brighter views than a 60mm scope, and the built in zoom lens produces sharp images from 20X all the way up to 60X magnification. The Ultima 80 features a sleek, waterproof design and includes a padded soft case with zippers on both ends so the scope can be protected even while mounted on a tripod. Including the eyepiece the Ultima 80 measures just over 18 inches long and weighs about 3.6 pounds. The rubber eyecup can be removed to expose a standard “T-thread” for attaching a camera. I like the 45* angled eyepiece because I can use a shorter tripod to support the spotting scope while viewing or while taking pictures with a small camera attached to the eyepiece. The focus ranges from 27 feet to the horizon with just a few turns of the focus knob. When I fold down the rubber eye cup I can keep my glasses on and see the whole 2 degree field of view at 20X magnification. With my glasses on I need very little focus adjustment while I crank the zoom eyepiece from 20X up to 60X. Sometimes though I like to take my glasses off while observing because the view seems to have just a little more contrast and sharpness. I like the fact that the Ultima 80 gives me a sharp image either way. The drawback of the tradition crown and flint achromatic lens used in the Ultima 80 Zoom Spotting Scope is a bit of false color, also known as blue fringing or chromatic aberration. Blue fringing seems well controlled at 20X magnification, but it becomes increasingly noticeable as I zoom up to 60X. Celestron also offers the Ultima 80ED and the Regal 80 F-ED spotting scopes which use exotic ED glass lenses to virtually eliminate blue fringing and produce the sharpest possible high power views.

Things To Recognize When Buying Binoculars
With technology advances, our lives are becoming easier. Could you imagine if we did not have electronic computers today. The world would stop operating. That includes binoculars too. We will be covering some of the main things that you should be aware of when buying binoculars today, but there are many more that just what will be listed here. Some could be how much are you willing to spend, another is what are you going to be using them for, do you know what you want (the features) and also the quality of the lenses. Here is just a very small list of things to consider. We will try and go through the main points of each one at a time.
Depending on features, how much you spend can limit the features
Another question is what are you willing to spend on your new pair of binoculars? This can also limit the type of binoculars that you can buy too. This is going to be a big limiting factor. It will also determine the quality of the binoculars too. Now make sure that you check around to find the best deals. These deals may be online or could be in a store right in your neighborhood. Not only will the price and how much you want to spend have to do with the quality of the binoculars, it is also going to determine what if any warranty you get. Make sure you check on this. Spending a couple bucks more today can save you a lot in the future. Now that leads us right into the next topic...
What will you use your new binoculars for?
Make sure that you know what the binoculars will be used for? This is a big factor to think about. Weight is something that you need to consider when it comes to what you will use them for. You don't want to be lugging around a big heavy pair when you are going to be out hunting all day. Higher magnification and clarity if you are a hunter is something that you are going to need and this may add some weight to those binoculars. You might want a range finder built in. Sometimes your eyes can get tired, you can get headaches due to eye strain. Some binoculars come with eye relief. Eye relief is the distance from the eyepiece to the point where you can see the whole picture. Easy to carry, the compact zoom binoculars are great for bird watching. They are durable and suitable to be carrying right in your hand. You don't need to be carrying around some heavy pair of binoculars if you are doing some bird watching. Astronomy binoculars are just what you need if your are a star gazer. These binoculars allow for a lot of light to be passed into the optics even at night when there is little light. A fantastic pair of astronomy binoculars is the Celestron brand. Going yachting or if you are going to be out on the water a lot, then you should consider a pair of binoculars that are waterproof, durable and maybe even have night lighting with a compass. There are some ideas for you on this topic...
Do you know what features you need in your new binoculars?
What features are you needing? Depending on what features you need is going to determine quite a bit on how much your binoculars are going to cost. There is a big difference between what you need and what you would like. Your cost can really go up quite a bit. So get what you need. If you are bird watching, get a nice compact pair of binoculars, which is probably all you need for this hobby. Marine binoculars will be waterproof, most likely have a lighted compass for navigation at night. These are things you need in a pair of binoculars if you are going out on the water. With the examples above, it is easy to see how the features fit in to what you are going to be using the binoculars for. Get what you really need instead of what you would like. This will keep your cost down too.
If you want great lenses then plan on spending a little more
How about the quality of the lenses? Good quality lenses will cost you more, but it will be worth it when you are looking through those lenses. Lenses today are made in a variety of different materials. Some include glass, high tech composites, quartz and even plastic. Special coatings on the lens can help to increase different factors. Factors that can go up with special coatings are the resolution and the clarity of the image. This will give you the highest advantage you can have over those cheap inexpensive binoculars.
Now understand that I did not go through all the factors that make up a great pair of binoculars. But I did go over the main ones, which you should understand now. Some good brands of binoculars are Steiner, Nikon, Carson and others. Learn more by visiting where to buy binoculars below.
