Leupold 173788 overview

  • 1Description

The 10x42 BX-1 McKenzie Binoculars from Leupold feature phase-corrected BAK4 roof prisms and anti-reflection fully multi-coated optics that work together to produce a versatile and capable optic with bright and clear high-contrast images and accurate color rendition. Coupled with the optical features are 42mm diameter objectives that boost its light-gathering ability, without the bulk and weight of larger models, for easy use in challenging conditions such as the early morning and late evening. The combination of optics and objectives make the McKenzie ideally suited for most long-range needs and outdoor activities from hunting, to birding, to sporting events.

Complementing the optical performance are construction details that make these binoculars durable and comfortable to use. The lightweight and durable aluminum alloy chassis is protected by a gray rubberized armor that is textured for a non-slip grip. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperatures or environmental conditions. A right-eye diopter adjustment and twist-up eyecups allow the binoculars to be customized to most people's needs and can be comfortably used with or without eyewear. For long-term glassing, the McKenzie is tripod mountable with an optional adapter.

Optical Performance
  • 10x magnification allows for detailed observations of distant subjects
  • 42mm objective lenses improve light-gathering ability versus smaller objectives while helping to maintain a compact form factor

  • Phase-corrected prism coatings reduce internal interference to improve contrast, clarity, and resolution

    Leupold 173788 reviews

    10x42 BX-1 McKenzie Binoculars (Shadow Gray) is rated 4.9 out of 5 by 16.
    Rated 5 out of 5 by from Great optics! Received these for Christmas 2016 after complaining to my wife about my other binoculars fogging up during hunting... and these are GREAT! Vision is so sharp and clear, can see individual leaves on neighbor's shrubs half a block away! Love the way they feel in the hands and very light compared to my previous binoculars. ONE DEFICIENCY: I am not real impressed with the provided neck strap so will probably replace with a better one; this was also noted in a previous reviewer's comments. But this is so insignificant I can't lower the rating because of an accessory... just hope they will improve it. GREAT OPTICS though... can't wait to get them out on a hunt!

    Rated 4 out of 5 by from Excellent Quality and Price! The Leupold 10X42 BX-1 McKenzie binoculars are an excellent general purpose tool. The size and weight is just right for all-day field use. Being water and fog proof is great for the New England areas I hunt and hike in. The optics appear crisp and bright. I like the 10 power magnification for hunting, sports, and animal and bird watching. The body has proven durable. The rating of 4 stars instead of 5 is because the accessories are merely adequate. A better strap and lens caps would put this product into 5-star territory, based on price, features, design, build quality, and Leupold's warranty, in my opinion. Still, a great product which will likely provide years of dependable service.

    Rated 5 out of 5 by from Great Binos I bought these a few weeks ago and so far I absolutely love them. I bought them mainly for hunting, they're light-weight, incredibly clear, comfortable to use and they are easy on the pocket book. Can't wait to use them this fall for elk, if you're going to be looking through your glass all day, get some quality binos like the McKenzie.

    Rated 4 out of 5 by from Love this product, but one thing lacking. Once again Leupold has created an amazing product. However, I could not give it the 5 Star rating, due to the strap that is designed for it. The strap is way below standard for such a supreme product. A more durable side-strap, not flimsy in its design would make this product beyond outstanding.

    Rated 5 out of 5 by from Great optics Got my Leupold bx1 binoculars yesterday, they are without a doubt the clearest sharpest binoculars I've ever owned. It's snowing a little here today but I can clearly see through my window, trees and individual branches on a hill about a mile away from my house. They are comfortable in the hands, easy to focus and nice and sharp with or without my glasses on. Im very happy I chose to go with these over other brands that I was considering.

    Rated 5 out of 5 by from Best Value for Price PERIOD I bought these for my daughter for Christmas 2016 and they have performed flawlessly. They are sturdy as all get-out and the clarity is equal to that of far higher-priced binos. I like them so much that I plan on purchasing this exact model for myself today. I've done a lot of research on numerous brands and models and these are by far THE most bang for the buck!

    Rated 5 out of 5 by from Great for the price. I liked the pair I bought last year so much that I bought one for my wife. Very bright and sharp. We are National Park vacationers and these binoculars are perfect for it.
