Color: 7X50
We'll start with the cons first: - You have to know either the height of the object you're looking at or the distance to it to find out the other. It's not a point-and-shoot rangefinder, if that's what you want. - They're a little chunky. Size is biggish, weight is a little on the high end for backpacking. That said, the pros: - These are spectacular binoculars. Easily read a street sign at a hundred yards like it was 20 feet away. Could probably double that range comfortably. Can pick out details of a car well enough to tell what make and model it is (if you can do so by sight normally, without reading the badging) at a full mile. - Have not tested the waterproofing yet, but the way they're put together, I don't doubt they are in the slightest. - While the rangefinder is kinda crap, the compass is insanely handy and is designed to minimize unnecessary battery usage. - Easy to focus. - Despite their weight when you're holding them, they seem almost weightless in their carrying case. Go figure. But the biggest pro is that their customer service is spectacular. Mine arrived with a very minor issue, and it was immediately taken care of, above and beyond my expectations. These are perfect for birding, camping, stargazing, or hiking. Their weight is offset easily by their usefulness in orienting yourself to a distant target using the internal compass, and being able to choose a path well in advance. 10/10, would absolutely buy again. ... show more

    • Well Made Optics
Color: 7X50
Although we have other binoculars, we needed a waterproof, boat ready set. These are well made, optics are clear, and focus is easy. Having dealt with inferior glass before, I was surprised at the quality for the amount spent. These are tack sharp and the compass is an added plus. Certainly would recommend these as an extra pair for your boat. ... show more

    • Bought Steiner Bincoulars for triple the price too.
Color: 7X50
I have both, the ESSL product and Steinier Navigator Pro (German Mfg’er). I figured some on else on the boat might like to take a look too. So some thoughts: Cost: ESSL ~$125,vs. Steiner ~$400 Performance: The ESSL performs >80% as well (arbitrary assesment not based on science) Some thoughts: The difference is in the little finish details, as you would expect the German product represents extreme quality, fit finish, every detail is pure BMW like. The ESSL image clarity is very good approaching that of the Steiner, light gathering of the Steiner is superior (viewing at dusk or night I grab the Steiner). Both are waterproof and float so they say. I do not plan to “test” this but am hoping if we drop them off the boat, they can be recovered., I can ... show more

    • Effective for in-the-field observations
Color: 7X50
I am a protected species observer and spend much of my time outside in the marine environment. After my first pair of binocular broke, I found myself in need of a new pair. This one ticks all the boxes for what I am looking for. Not overly heavy or cumbersome. They are 8 reticles. Oculars are reasonable, and focus is good. If you want a decent pair of binoculars that can hold up to the marine environment that don't cost and arm and a leg, I would recommend this pair. ... show more

    • This item is NOT night vision. IT IS night vision compass, meaning" glow in the dark" compass dial
Color: 7X50
Misleading advertising in description. Night vision compass means just that, glowing compass at night so you can see the compass, NOT a NIGHTVISION binoculars. Which I thought I was buying. My bad I guess. Bad for Amazon popping it up when I searched for Night vision binoculars.I Returned this Item because it was not what I thought It was. In its defense, it seemed to be very well built, but it's not "Night vision" ... show more

    • Decent set good for the price
Color: 7X50
It is nice to be able to see a compass direction when Navigating at sea. The night light did not work on the unit, and the prisms are slightly off giving a little bit of Double vision, but for the price it did what I needed it to do. I would save my money for a better pair in the future.
