Nikon Prostaff 3S Binoculars Review

This Prostaff 3S 8X42 has a low budget price at roughly $130 with high-reflectivity silver-alloy mirror coatings and multi-coated Eco-Glass lenses. It has an amazing, extended eye relief of 20.2 mm, a proficient 5.3 mm exit pupil, wide field of view, and is incredibly light weight for its build class, weighing only 19.9 ounces!

So far online, there’s barely any buzz about it since it just hit the market in 2016. But, what little has been said about it is unbeatable this far. It has gotten off to a strong start with a top rating that mightn’t be too hard for the Prostaff 3S to hold in the coming months ahead.

Being so new to the market, it’s impressive to see this binocular any where near the Top 100 Seller’s binocular list, so it snagged a spot in this review. With its “new car” smell and low budget price tag, I wouldn’t be surprised to see it gain a few spots ahead in the Top 100 list.

To see if this Prostaff 3S is worth the attention its attracting, I’ve provided you with the Q&A for you to decide for yourself.

PROs:
  • Price
  • Wide field of view
  • Extended eye relief
  • Fully weatherproof
  • Compact and lightweight
CONs:
  • Poor quality eye covers

 

Prostaff 3S 8X42 Binocular Q&A:

What is high-reflectivity silver-alloy mirror coatings?

Here’s the short answer. All roof prism systems are going to need two types of coatings: phase coatings and mirror coatings. This is the mirror coating that allows light to be reflected throughout the light path in the barrel to ensure light reaches the eyepiece.

What’s so good about this one?

Long answer: A silver mirror coating is typically a step up from the aluminum mirror coating. While the aluminum coatings have a reflectivity of 87 percent to 93 percent, silver coatings have a reflectivity of 95 percent to 98 percent.

Better yet is the dielectric high-reflective multi-layer prism coatings that are seen on the Monarch series binoculars mentioned in this Nikon binocular review.

Bottom line: Combine this highly reflective mirror coating with multi-coated lenses and 5.3 mm of exit pupil and you have the potential for some bright, sharp, and pure picture quality.

 

Is this a compact binocular?

You betcha! This Prostaff is not only smaller in dimensions, 6 x 5.1 x 2.0 inches, it’s also light weight for a binocular in its class. It weighs a light 19.9 ounces whereas similar models are about 23 to 26 ounces.

A binocular in the 20-ounce range is still generally considered light weight. But, being able to keep glass quality, an all-round and ideal magnification, and classic-sized objective lenses for under 20 ounces indicates it will be a compact and great hand-held unit.

 

How much does the Prostaff 3S 8X42 cost?

For an all-purpose binocular, it’s arguably in the right price range for its quality – approx $130. While there’s nothing really fancy about it to kick its price tag into the additional zero digit fields, there’s enough about it that makes it an ideal optic for hunters. The low budget cost is like the honey pot for the bear – irresistible.

 

Does the Nikon Prostaff 3S have long eye relief?

If you thought that eye relief only applied to rifle scopes, then you’re probably a rookie new to optics. Don’t feel bad – we were newbies once upon a time too. But, this Prostaff 3S sports a fantastic 20.2 mm of eye relief. Now, this is what I would call extended or long eye relief.

If you’re thinking that maybe this is too far out for you to feel comfortable, the twist up style eye cups have the multi-setting click stop rubber eye cups to adjust for a custom fit.

But, if you’re a spectacle-wearing, sun shade-donning kinda guy, then you’re definitely going to appreciate the long eye relief these pair of binos afford you.

 

Noteworthy Features:

  • BaK-4 prisms for optimal glass quality
  • Multi-Setting Click Stop rubber eye cups for a variable, comfortable, and easy to set custom fit
  • Arsenic-free and lead-free Eco-Glass technology
  • Rubber armored body for non-slip grip and repeated and heavy use
  • Fully weatherproof and fog-proof for all-weather use
  • Backed by Nikon’s 25 Year Limited Warranty and No-Fault Repair/Replacement Policy

 

Our Verdict

To glass it up, the Nikon Prostaff 3S 8X42 is an impressive, little unit with a lot more punch than you’d initially give it credit for. There are no legitimate complaints on this piece of work. The included accessories can be better quality, but that’s nothing an extra $20 can’t replace.

Sticking with the same optic specs, the Nikon Aculon A211 8X42 (which you can take  a look at here) brings down the cost quite a bit. Granted, you’re not getting the ATB perks of the Prostaff, but the cost drop might be enough to swing you towards the Aculon.

Of course with specs like these, we’re going to pin the Prostaff against the Vortex Raptor 8.5X32 binos. Yes, it’s cheaper, but Vortex is known for quality and their VIP treatment of customers. That’s all we have to say about it. Check it out to see what we’re hinting at.

It doesn’t matter if you’re spending $1000 or $100 on a Nikon. The point is, you’re getting a high quality optic with Nikon’s reputation with your purchase. Trusting them with your business is trusting Nikon to make a precise shot in the field. Put your faith in Nikon and you’ll be ready to fill your tag this hunting season!
