Leupold BX-4  Binoculars Quality

Leupold BX-4 Quality 95/100

The quality of all Leupold optics is legendary and the BX-4 Binoculars are no exception.

That quality is guaranteed and upheld by Leupold's famous full lifetime warranty which states:

From the Website

"If your Leupold riflescope, binocular, or spotting scope doesn’t perform, we will repair or replace it for free - whether you're the original owner or not. You don’t need proof of ownership or a warranty card, and there’s no time limit. We do this because we believe in superior quality and craftsmanship, and we’re confident your Leupold won’t let you down."

The quality of the Leupold BX-4 binoculars is evidenced by the rugged aluminum body that is rubber armour coated, along with bak 4 prisms and fully multi coated lenses, making the Leupold BX4 a top choice for the best binoculars for hunting.

Design and Functionality

Design and Functionality 95/100

The design and functionality of the Leupold BX-4 binoculars is superior to all of the less expensive binoculars on the market today.

They are ergonomically designed to be slim, lightweight and to fit comfortably in your hands.

Couple that with the revolutionary open bridge roof prism design and High definition, calcium fluoride lenses and you have a high quality set of binoculars that are a joy to use and will provide many years of trouble free service.

We should also mention that they are 100% waterproof and fogproof thanks to being nitrogen purged.

Nitrogen purging is a technique that Leupold invented while making machine gun sights and navigational devices for the United States military during World War II.
