ProSport 12×50 Binocular Q&A:

What are the advantages of having a roof prism Simmons binocular?

Roof prism binoculars have been quickly gaining popularity over the years. The more streamlined build, the sleeker appearance, and the lighter frame has had users looking towards the roof prism binocular for their hunting needs.

Another advantage is that they’re typically going to be made more sturdier, rugged, and durable than a porro prism binocular. For hunters out in harsh terrain or with clumsy paws, this is a benefit to keep note of.

The disadvantage is that they’ll cost more than a porro prism bino because it costs more to make. To be optically equal to a porro prism, it needs reflective mirror coatings and phase-correction coatings to get it on par.

With the extra reflections that light needs in a roof prism system, more technology and intricate manufacturing is vita.


What are some tips to keep my Simmons Prosport binocular lenses clean?

If it has never crossed your mind to keep your lenses clean, then this “tsk tsk” is for you. To get any binocular, low budget or premium, to last you a lifetime, you need to take care of it – properly. That means more than just putting lens caps on and stowing it away in the travel case.

When you’re out in the woods, the swamp, or the plains, you’re going to get a little dirt, dust, and grime on your binocular. And, even with the most careful practices, you’ll still going to get a splash or two on the lenses.

To ensure you’re not damaging your binocular in the cleaning process, you’ll want to learn how to remove this gunk appropriately.

If you have one of those electronic air/dust blasting cans, use it to get rid of excess dust and dry dirt. You could also use a soft brush to remove this as well.

If you got your sticky mitts on the lens, wipe it off in small circular motions with a cotton swab or eyeglass tissue that’s been dabbed with a mild and soft soap-to-water solution. Now you can use your eye caps and travel case.


How do I adjust for uneven eye strength when looking through binoculars?

This might seem like a toughie for you calibrate your binoculars for your eyesight, but it’s really not a big deal. You’ll want to pay attention to these instructions since many people don’t even realize that each eye has varying eye strengths that are just as unique as fingerprints.

To make sure that you’re getting the most potential out of your Simmons ProSport 12X50 binocular, follow the simplified steps below. For a full run down on adjusting your binoculars, check out our ‘4 Essential Binocular Adjustments’ article.

  • Use the binocular hinge to get the right interpupillary distance for your eyes.
  • If you have a variable zoom binocular, adjust the power setting to the highest magnification.
  • Zero the diopter and look at a far-away target.
  • Cover the objective lens of the diopter side (right side) of the binocular.
  • Rotate the center focus knob until you have a clear and sharp image.
  • Uncover the diopter side and now cover the left side.
  • Adjust the diopter until you have a clear and sharp image.


What is interpupillary distance?

To get the most out of this 12X50 binocular, you should know what it means first. The IPD is the small distance from one pupil to the other. Now this distance is going to be different for everyone – this supports the importance of properly focusing your set of binoclars for you.

But, how do you get the right distance?

Most binoculars will have a hinge or some sort of feature to enable you to start bringing in the barrels of the binocular closer together.

Starting from a fully extended outward position, just bring it in towards the middle in an inward position until the two circles you see through the binocular make one full circle. Voila – you have your IPD.


Noteworthy Features:

  • BaK4 glass in roof prism design for excellent image quality
  • Powerful 12X magnification for long distance viewing
  • 100% waterproof and fog-proof for optimal survival in harsh weather
  • Multi-coated optics for brilliant image quality and maximum light transmission
  • Tripod adaptable for steady and still viewing
  • Durable rubber armor body for secure gripping in wet and harsh conditions


Our Verdict On Simmons’s ProSport 12x50mm Binoculars

To glass it up, the Simmons ProSport 12X50 binoculars are a good pair for the money. Who says? The masses and us. However, even for its nice perks, it isn’t as clear as it should be to be able to tell subspecies apart, if you’re birding. But, for general viewing, you’ll do just fine, especially since people and elk are much bigger than birds.

The ProSport 10X50 binoculars are approximately half the cost of the 12X50 binoculars. When hunting on the go, that extra 2X magnification isn’t going to be as important as the wider field of view the 10X50 binoculars are going to offer. However, the 12X50 binoculars are still weatherproof and have more forgiving eye relief. The best thing to consider when deciding between the two is what’s more important for your needs and your style of optic use.

You won’t always have to go bigger to get that extra distance. The Nikon Action Extreme 10×50 ATB binoculars will get you the distance you need come rain, snow, and fog. Plus, you’re getting extra feet in the field of view without compromising on eye relief. However, you will have to pay a little extra for the Nikon, as expected.

Simmons keeps prices in check for the cost-conscious optic user. In fact, the low cost is often the big draw card for most shoppers. It’s why you’re in this review right? Point proven. Go with Simmons, it’s easier on the credit card.
