Cornell Underground Weather

I had read a review of these from a study at Cornell University and bought them w/o trying them in a store. No problems whatsoever. They feel great in my hands, very smooth focus, no problems with using them while wearing my glasses. They have greatly exceeded my expectations. Additionally they are a fantastic value.

Found the recommendation by Cornell University's Ornithology department. Light, compact, sharp, bright, and rugged. These fit well in my backpack and they do seem smaller than they are.

Recommended by the Cornell Lab of Ornithology for birders on a tight budget, this delivers great optics for the price.

Cornell University did a review on binoculars recently, and said this was there #1 choice (well, same brand and model, but they tested the 8x42), when taking into consideration the cost of the binos and their quality. I have now used them for a week in the field, and I am 100% satisfied. They are great. Just what I had hoped for.

Was looking for binoculars to do bird watching. Tried out the ones recommended by Cornell lab of ornithology. They did not have the clarity or sharpness that I found with these binoculars. Very easy to adjust and balanced for steady viewing.

Great vest. I'm using it in an underground coal mine. It's like having an extra pair of hands. It distributes weight evenly. I use it for batteries, flashes, all sorts of accessories. There are no pockets for big lenses, but that's O.K. It would make the vest too heavy and cumbersome. It's pretty good at repelling lime and coal dust and water and is not likely to tear easily. Pockets are lined with soft material, which is easy on lenses. These vests are a little pricey, but worth it. They're professional gear and are made for rugged use.

Solid takes abuse perfect for poking the gopro into strange places underwater and underground.

So far so good! Using as a backup power supply for an underground dog fence and so far is working great.

We mostly use it to protect our lens for our camera at work, being as we drag the camera through steam tunnels, in mud trenches, inside underground vaults, and through all sorts of other environments. The filter screws on firmly to the end of the lens and protects the lens from scratches, dirt, dust, etc. without distorting any of the pictures.

I use 50+ of these routinely for delicate electronic sensors that are buried underground in very wet Florida environments for over 6 months at a time. I love the color-changing pattern on the exterior of the pack that let's me now when it's due for replacement or refreshing in a microwave. I used to use the metal type that needed to be baked for 3 hours, but those too long to replenish and were small in comparison.
