Celestron 71370 8×42 Granite Binocular Review

A good pair of binoculars can make a big difference when outdoors. It can bring you closer to your target when hunting and allow you to see more detail from a distance. However, the pickings are quite large and this makes it harder for many people when it comes to finding the perfect set of binoculars for the job.

Celestron has never been one of the cheapest brands and when we look at the Celestron 71370 8×42 Granite Binocular we not only see the expensive price tag but some of the features that make it stand out from the rest. In this article, we will be diving a little deeper into the set of binoculars to see if it might be the perfect option for you.

Technical Specifications:

  • Fully multicoated lenses for better light contrast
  • 8X magnification with a large 42mm objective lens
  • BAK-4 prisms that have been phase-coated
  • Nitrogen purged to make it fog proof and waterproof
  • Large focus knobs for easy adjustment
  • Durable metal body enhances durability
  • Safe for the environment, being lead and arsenic-free
  • Includes a durable carry case with additional neck straps


Whether you are a beginner or an avid outdoorsman, having a decent set of binoculars can be really hard, especially if you are not willing to spend a little extra. The Celestron 71370 8×42 Granite Binocular is definitely not the cheapest, but it does make sense when you look at the durability. The main part of the body has been constructed from durable metal components, while all of this is rubber-coated for more durability.

Since the unit has been purged with nitrogen, it offers more resistance to some of the outdoor elements. Things like water and fog tend to inhibit many people when they are outdoors. However, this has been limited due to the design. With a 42mm objective lens, it also offers some of the best light dispersion to ensure that you have a clear view.

The lenses are multicoated, but that is not the only great feature. Since the BAK-4 Prisms that are used in the design are also phase coated, you have much better contrast. Compared to binoculars without a phase-coated lens, you don’t need to wait for a specific time of the day for them to work at their very best.

Additionally, weight can be a concern for some people outdoors, especially when backpacking. Since these binoculars have and open-hinge system, you can keep the weight down slightly. They fold according to your specific needs and this also makes the binoculars more ergonomic for those with smaller hands.

Since the eyecups are something you need to look at, especially when you have glasses, I have noticed that it features twist eyecups. This allows you to twist the eyecups up or down depending on what will give you the best comfort. Those with glasses should be happy to see that an eye relief of more than 17mm has been accounted for when used.

Something that not many people look for is that the unit is eco-friendly. In a world where climate change is happening daily, Celestron will be the first to point out that the unit is eco-friendly. It does not have any traces of arsenic or lead, which makes for a much better unit when you need to spend hours in the wilderness.

The feature that stands out the most and also spikes the price is definitely the type of glass that has been used. Celestron has added ED or Extra-low dispersion glasses to the binoculars before it has been multicoated. When you look through it in bad lighting conditions, it can definitely improve the overall sharpness of the image.

Hunters and trackers can attest to the quality of the unit simply by looking at the field of view. The Celestron 71370 8×42 Granite Binocular has a 426-yard field of view at 1000-yards. This also translates to 8-degrees and it ensures that the user can easily keep track of the target. Many birdwatchers will also find it helpful.

One of the only downsides is the softening of the image, However, this will only be noticeable when you are actively looking for it since the unit will basically force you to look directly at the target in the center. Aside from the price, it is hard to find any other bad features that could dissuade someone from buying it.

What We Like:

  • Large field of view
  • 17mm eye-relief
  • Lightweight and includes a neck strap
  • Made from ED glass
  • Waterproof and fog proof
  • Includes a limited lifetime warranty

What We Didn’t Like:

  • The softening of the image
  • Expensive (High-End)

Should you buy the Celestron 71370 8×42 Granite Binocular?

Unfortunately, this binocular is not for everyone and some people will argue that it is really expensive. The truth is that it does command a high price, but you won’t find some of the same features for a cheaper price. It has been designed specifically for professional outdoorsmen that like to get out more often than not.

If you fall in the category of someone that loves exploring, or you hunt from longer distances, this can be a big compliment to your scope. The 8x magnification is better than most modern scopes available for commercial use. I would recommend it to avid birdwatchers and hunters that are looking for something special.


The Celestron 71370 8×42 Granite Binocular is an older binocular that is still highly regarded among some of the experts. It is not something that you will buy if you are not going to use it due to the expensive price tag. However, it looks and feels great. I should also mention that the ergonomic feel makes it perfect for people of all ages. Hopefully, you have found the answer that you are looking for and we believe this binocular will make your life easier. If you’re looking for options, have a look at our Best List here.
