Leupold BX-2 Cascades Binoculars Review

This Leupold BX-2 Cascades 10X42 binocular has L-Coat BAK4 Prisms, short close focus distance, and a great twilight factor that was all put together under the Synergy Built project. It’s also fully waterproof, fog-proof, and has a durable armor coating that gets you a great grip while protecting it.

Hunters are pretty excited about the newer line of Cascades – they have a fantastic rating online. If you make your purchase decisions based on ratings, then this is a great one right here! At around a cost of around $300, this premium binocular is one of the better deals Leupold has.

But, will the Cascades binocular be good for more than just hunting? How about in the hands of my clumsy teens? For everything you want to know about this all-purpose binocular, feel free to address the Q&A.

BX-2 Cascades 10X42 Binocular Q&A:

Which Cascade should I get – the 8X42 or 10X42?

The Cascade 8X42 binoculars are going to be an excellent binocular for most of your needs. If you prefer the wider field of view, larger exit pupil, and longer eye relief, you’ll want this model.

The larger exit pupil of 5.25 mm will be excellent for low light hunting conditions. And, if you’re in close range hunting grounds like the woods, the 8X42 will be your short distance pal.

This Cascade 10X42 on the other hand has the most popular binocular platform that hunters can’t get enough of. While you are compromising on field of view and exit pupil, you’re gaining the higher twilight factor of 18.30 and a higher magnification – perfect for the open plains.

You might want a tripod if you’re going to be bird watching or you need to see the pulse of your target from long distances. When you need intimate detail at such high magnifications, you’ll need to eliminate hand shaking and any slight movements to get the maximum performance out of your binocular.


How can I tell the differences between Leupold’s binocular rating system?

This can get a little confusing, especially if you’ve noticed all the Xs and letters. Right about now, you’re probably wondering what it all means. Well, Leupold uses a rating system of their products to indicate to the level of quality glass, lens coatings, build, etc.

To start with, the rating sequence starts with a letter that precedes the letter X, followed by a number. For the first letter, riflescopes start with a V, spotting scopes start with an S, and binoculars start with a B. The number then indicates the level of quality the binocular falls into.

For example, the BX-1 Yosemite 6X30 indicates that the Yosemite is an entry level binocular.

This particular BX-2 Cascades 10X42 has a mid-range quality with slightly better optical performance and quality than a BX-1. Likewise, BX-3 binoculars are Leupold’s premium products. And, the golden ring featured on top-shelf Leupold products indicates that they’re made in the good ol’ USA.


What kind of eyecups does the 10×42 Cascade  binocular have?

This BX-2 binocular has twist up eyecups that provide a custom fit to help you find the sweet spot suited for your comfort and vision. It’s definitely the most popular design because the forget-it and set-it feature makes it easy to use and easy to like.

It has a standard 16 mm eye relief. If you’ve got really long eye lashes or if you wear sun shades and spectacles, this amount of eye relief is going to be helpful.


What is the Cascade binocular’s close focus distance?

It’s a close 9.90 feet. For an all-purpose binocular, this a great figure to see, especially when somewhere between 15 feet and more is considered “okay”. It still doesn’t compare to champion binoculars that come in at a close 3 feet.

But, if you’re the typical hunter where you just need enough to see the 4X4 rack on a bull and not the chiggers on its underside, then this 10X42 and 9.90 close focus distance is going to be more than enough.

Noteworthy Features:

  • Twist up eye cups for a true custom fit for any user
  • BAK-4 prisms for leading-industry glass quality with L-Coat cold mirror phase coatings for ultimate prism performance
  • Fully multi-coated lenses provide maximum light transmission for bright, clear images
  • Fully waterproof and fog-proof with Leupold’s proprietary Nitrogen fill process
  • Manufactured under the Synergy Built project
  • Armored body for heavy use and easy gripping
  • Backed by Leupold’s Full or Limited Lifetime Guarantee


Our Verdict on the BX 2 Cascades Binoculars

To glass it up, the Leupold BX-2 Cascades 10X42 is one of those binoculars that no one can hate, which is why it earned a spot on our best binos below $300 list. In fact, this is so true that there’s not a single person who hates the BX-2 Cascades. As far as the binoculars themselves, there’s not a single complaint. But, could the included accessories be better? Definitely.

However, it’s not always about the accessories that counts when making a binocular buy, sometimes, it’s about the finish. It’s okay to be a little vain. The Leupold BX-3 Mojave 10X50 will cost you a pretty hundred more, but you’ll be gaining the awesome Mossy Oak finish with it as an option.

Moving past vanity and side accessories, the Nikon Monarch 5 10X42 is one of our favorites to pit against the Cascades. According to the masses, it’s one of their favorites too. Be warned, there is a price jump, but it seems it’s worth making the leap if you want the best – so check it out, it’s only a click away.

Leupold needs little praise from us because their optics tend to do all the praising for them. It’s why we feature them at all. So, what do you say? Are you a loyal Leupolder yet? Come on, get on the band wagon and cheer on “Rah-rah Leupold!”
