What Customers Think

We are not the only ones to have been enthusiastic about these waterproof binoculars. Their quality, as well as the reputation of the brand, has prompted many amateurs to acquire them. We pick up some Bushnell H2O 10×42 Binoculars Review from online for your better judgment.

I had used Porro prism binocs earlier, but these roof prism ones are so much more convenient and lighter to carry during hours of treks. And I personally tested the waterproofing claims of this product when I dropped them into shallow waters during a kayaking trip – I wiped all the water off, and it was ready to go in moments. Overall, an excellent deal – I bought the 10×42 H2O when their price came down in Sep 08. So, it was a brilliant deal I got. But I’d buy it again if something happened to my current one and I had to pay $99 for new ones.


I bought this model for an outdoor cruise a few months ago. It was a right choice. Our team had a variety of binoculars ranging from the cheap to high priced (which did not work at all). For my personal use, these worked the best. I did notice the captain of one of the excursion vessels had the full-size version of this exact binocs. Yes, they are waterproof, and I needed them to be. Easy to focus. The right magnification for viewing eagles, whales, glaciers, etc.


I purchased these binoculars mainly for the purpose of watching football games from my upper-level seats. The view of the field is very sharp and clear. During night games the view through them is surprisingly brilliant. It seems to gather in light very well. For a full-size binocular, it’s not as bulky as I thought it would be. To me, it’s just a little bigger than a pair of compact binoculars. The only problem I had with them is that they were a little heavy as they hung around my neck. And because of the weight, I had to actually hold it steady with two hands if I wanted to keep the image I was looking from shaking. Other than that I was happy with the binoculars overall.
