The best budget porro prism binoculars.

Our Ratings:

Note: The “Our Ratings” section rates based on the product’s price. Therefore, a 5/5 for a cheap binocular is much different than a 5/5 for an expensive one.

  • BaK-4 prisms for bright, clear, crisp viewing.
  • Multi-coated optics for superior light transmission.
  • Water and fog proof
  • Non-slip rubber armor absorbs shock while providing a firm grip.
  • Twist-up eyecups.
  • Large center-focus knob for easy adjustments.
  • Longer eye relief.

  • 1.69 lbs
  • Magnification 10x

The Bushnell H2O Waterproof/Fogproof 10×42 Porro Prism Binoculars are an adventurer’s dream. They’re easy to make comfortable, with a large, center-focus knob for getting the perfect sharpness and twist-up eye caps, and the crisp image is to die for! 

From being able to count the spots on a distant dolphin’s back or identify the tiny, flitting bird in a far tree, the clear and sharp 10x magnification of these bad boys lets you see as close as is possible before needing a tripod for stability.

Even if dropped on the ground or left under a sunken canoe in a lake for an hour (as one reviewer did), these are near-indestructible.

This pair does well in cloudy or dusk conditions too.

Most folks that’ve used the binoculars nothing but good to say about their image and only cautioned that the strap left a little to be desired (considering the weight of a porro prism pair of binoculars) and that the lens caps were easy to lose, as they don’t attach to the pair.

2. Nikon ACULON 10-22x50 Binoculars

Best bang for the buck porro prism binoculars.

  • Birding- (4/5): A bit more magnification than you will need, meaning you can see even
    the furthest aviary beauty. If this is your price range, these binoculars will suit you well.
  • Viewing Wildlife- (4/5): Again, a bit more strength than you’ll need, but the image is
    crystal clear and you’ll probably find creatures you didn’t even know you were looking for!

Pros:

  • Fully multi-coated lenses 
  • Good eyecaps 
  • Great clarity 
  • 25 Year No-Fault Warranty

The Nikon 8252 ACULON A211 10-22×50 Zoom Binoculars are an exciting tool to add to your adventuring bag because of the adjustable magnification option. At the 10x setting (where you’ll probably keep it most of the time), these are sturdy, dependable binoculars. The image is clear due to the desirable multi-coated lens, the colors are great, and once users tinkered them to meet their personal eye strengths, they absolutely loved them!

Then, thankfully, you can up the magnification using an easy knob all the way up to 22x! After about 10x, the magnification gets so strong that a human hand will usually be too shaky, but Nikon sweetly thought of this and included a tripod adapter on the the binoculars. This way, you can literally zoom all the way to outer space and pick out the pinks of nebulas and yellows and whites of stars.

This pair is the most affordable way to be able to hunt, view birds, and do some light astronomy, because it’s all rolled into one, handy tool.

Steiner, with their marine/marine binoculars, make up a hearty portion of the mid-high range binocular market, and it’s easy to understand why, as they are the civilian version of what the military uses, so it’s safe to assume that these puppies can be counted on in wet and rough conditions.

Since they are military grade, this pair of binoculars is one of the most durable on the market. There are plenty of stories online about users of these binoculars being extremely rough with them and them remaining undamaged.

Great magnification combined with field of view mean that these do great in most lightings – even up to doing some astronomy at night for some users! Weather resistant and with a warranty, these are binoculars that can be counted on for a rainy hunting season, birding in salty ocean conditions, or can be even be loaned to a youngster without worrying that a drop will destroy them.

The image is sharp and there is nary a complaint – they do their job in any situation, and they do it well.
