As far as the build quality goes, they won’t disappoint you. They were designed with fairly high tech military standards, and nowhere is that more obvious than the armor. The non-slippery armor will both give you grip that’s more than sufficient for any user and provide fairly good shock absorption in case it’s something you happen to need, as it’s actually a rather rugged option. Inside, there is nitrogen gas. As mentioned with some of the previous models we spoke about, this will make sure that your lenses don’t get fogged up, even in high humidity situations or rainstorms. And wrapping things up with the build quality and construction is the fact that these binoculars with rangefinders are IPX7 water resistant, which should be more than enough for a variety of situations.
"Great binoculars. I have used these binoculars on my last vacation to Florida. I could not put them down. The 20 magnification allowed me to view the birds,dolphins and some other sea creatures from the balcony of my condo. It is like being in the ocean with the dolphins. The fact they are also waterproof was very handy since i dropped them in the ocean. I panicked,but they were just fine."
6. Use your binoculars to view beyond the Milky Way.  Let’s leap out of our galaxy for the final stop in our binocular tour. Throughout fall and winter, she reigns high in the sky during northern hemisphere autumns and winters: Andromeda the Maiden. Centered in the star pattern is an oval patch of light, readily visible to the unaided eye away from urban lights. Binoculars will show it even better.
But not all binoculars are created equally, and they are not one-size-fits-all either. Subtle differences in performance and quality can mean the difference between enjoyment and frustration. Active Junky pulled together some of the best binoculars on the market from reputable brands to help you choose which pair is right for your favorite activities.

Binoculars come in two basic configurations: Porro prism or roof prism. The Porro prism gives that type of binoculars the traditional binocular shape. The roof prism binocular features a narrower and compact, straight design. There are advantages and disadvantages to each, but, in general, the Porro prism design is less expensive to manufacture and, therefore, gives you more bang for your buck as far as optical quality and features. The relative compact size of roof prism binoculars makes them generally more popular for birders, as optically similar Porros will be larger.
Read product and user reviews on the brands you favor. The Internet features plenty of reviews on birding binoculars, from both expert and amateur birdwatchers. Consulting as many different reviews as possible will often result in the recognition of themes or patterns. Perhaps one brand is consistently more durable than another, or one style is overpriced compared to other models.

Another thing that’s worth mentioning is that each of the device’s independent diopters are adjustable. This is something you won’t find on many rangefinders. But, since this is a binocular combo, you’re actually getting a pretty good deal. The unit is right-eye-dominant, and the right diopter is what will focus in on the reading display, and you have the main focus adjusting the distance.
Inside, things are more or less what you’d expect from a pair of binoculars like these. The prism is a Hi-index BAK4 prism, which has been proven to give you a sharp and bright image, with plenty of contrast. When you’re looking at an object, you can be sure that you see every little detail of it. The 22 mm lens design won’t cause any eye fatigue, or dizziness, and your view will be a combination of HD and wide angle. The 50 mm objective lens, on the other hand, is large enough to ensure that even in low light conditions, such as at dawn, or at dusk, or even at night, you will receive as much light as possible inside, making the image bright.
“These binoculars are inexpensive but have many of the characteristics of expensive binoculars. They are water and fog-proof, they have BaK-4 prisms, and they have a well-constructed and rugged body. I purchased Roofs rather than Porros after my Nikon Porros lost their collimation. Nikon repaired them for $10 plus shipping (which was very fair), but I did not want to go through that again. Roofs are generally more durable. These binos appear well collimated (I did every test I could find on the internet, including shining the sun through them onto a screen), they can quickly be focused quite sharply, and there is very little color aberration. The 8x42s have remarkably little distortion near the outside of the field of vision; the 10x42s have more, but are still quite acceptable. The eye relief is good, so I can wear these with or without glasses.”
Our runner-up, the Celestron TrailSeeker 8x42s, have rugged, armored construction and were among the lightest binoculars we tested, at 23 ounces (the Athlons weigh two ounces more). Celestron has been making high-quality consumer telescopes since the 1960s, but also offers a huge line of binoculars (over 14 lines, and more than 30 different models).

You’ll recognize zoom binoculars by their name – the magnification factor is actually two numbers, such as 8-16×42. This tells you that you can go from 8x, to 16x magnification. You will notice that none of the binoculars on our list are zoom binoculars. There’s also the fact that there aren’t many high-end options as far as zoom binoculars go, only some lower priced pairs.

Whether you're looking for an inexpensive first pair of binoculars, or want a good, secondary, compact pair that won't break the bank, the Vortex DiamondBack 8x28 will serve you well. These relatively small bins tip the scales at just 15 ounces, yet can provide enough brightness and clarity to identify small birds on a bright day. Top that off with high-quality construction and a smooth focus knob, and you've got an excellent pair of budget bins.
Telescopes do make objects look larger. But their main job is to gather light. Paradoxically, the more a telescope magnifies an object, the dimmer that object appears. That's a problem when observing deep-sky targets like comets, galaxies and widely diffuse star clusters. It's an issue for everything, really, except the moon — which can be too bright — and a few vivid planets.
