In-depth information


The Eyeskey Waterproof 4331885369 provides high-resolution images with help from the multi-coated optics. The coating on the optics will minimize the loss of light due to reflection so that a more natural and clearer view is ensured. Thanks to this technology, you will be able to enjoy images that are crystal clear, and that won’t contain any unnecessary glare.

With such high-quality optics systems, these binoculars are the ideal choice to use during diverse outdoor activities such as hiking, hunting, bird-watching, viewing wildlife or watching sports events.

What’s more, you will get to enjoy great clarity when observing both near and distant focus objects through the high-index prisms that deliver crisp images with superior contrast and sharpness.

The binoculars are O-ring sealed and nitrogen-filled which guarantee the waterproof and fog proof properties of the unit. Fog, raindrops, and dust will not be able to get inside the product, meaning that you can expect reliable performance from this pick in any environment.

We also can’t forget to mention the price. It is one of the most reasonably priced products from Eyeskey. Of course, most brands do offer affordable alternatives, but what is truly impressive about this particular unit is that it was hard for us to determine where the company decided to cut corners.

Indeed, this unit seems to feature the same high-quality optics and materials as the more expensive Eyeskey products. Looking through the numerous consumer reviews, we noticed that owners too were very impressed with the quality and the viewing experience they got from the product. Thus, if you’re looking for a smart and cheap purchase, you won’t have to look too far.

Known issues


Finding a flaw with this product was quite difficult, but after sifting through the numerous customer reviews (most of which were extremely positive) we did notice a few users commenting that they had problems when mounting the 4331885369 model on a tripod. Due to the compact nature of the product, it appears it has difficulty in staying steady.
