The writer mentions Zeis,swavoski,leica & Nikon but another alternative with comparable glass and clarity is Stiener. As a captian running offshore fishing boats for years I have relied heavily on stiener binos with great success. I also have a buddy that is a Fish & Wildlife Officer and after using mine also purchased a pair, After using his nearly every day for about 3 years the focus adjusment started to become loose. When he called steiner and told them about the problem they told him to send them back and they sent him a new pair within 2 weeks. Great customer service, but the big selling point for me was the eye cups once you've put the steiners up to your face you'll never own anything else. Before you buy a new pair of binos try the stieners, you wont be sorry. The model that I use is the 10x42 Merlin, the Predator is supposed to be fiscaly the same but a little more rugged, but the Merlin was about $300 cheaper and having them on the boat all the time I would rather a $500 pair fall overboard than a $800 pair. Just My Opinion
