Specifically engineered and built to withstand the rigors of life on the water, Steiner's 7x50 Navigator Pro Binocular produce bright and clear images and reduce the disorientation commonly experienced when using optics in marine environments. Its large objectives gives the binocular high light-transmittance for enhanced low-light performance, and a large exit pupil which helps to reduce the effects of rough and rolling seas - which can cause disorientation during observation. The porro prism optical design combined with the fully multicoated optics provides high-contrast images with true color representation and long depth of field.

Each ocular is individually focused for precise customization for each user and will maintain that focus from 65' to infinity - so users can concentrate on the views, not re-focusing. To hold up to the elements, the housing is made of temperature and impact-resistant Makrolon polycarbonate. NBR rubber armoring on the exterior is resistant to oil, acid, and weathering, as well as providing a slip-resistant grip in cold or wet conditions. The optical tubes are nitrogen-filled for fogproof performance, and the Navigator Pro is waterproof to 16'.

7x50 Navigator Pro Binocular is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by from Great value I use these 7x50 for hunting deer at dusk. I hesitated between these ans the Marine 7x50 model. I choose the Navigator because they are Nitrogen-Filled. I had 2 binoculars who fogged inside , and i wanted a fogproof model. They are very crisp and clear. Especialy at twilight. And i can use them for very long periods without eye strain, or head hache.This is a very good quality binocular.I love them.

Rated 4 out of 5 by from Very nice! Not perfect, but worth the many. Excellent night vision. Compact, waterproof. Matirials quality 8/10 Day vision 7/10 Liltle chromatic adoration in day and some visual distortion. A bit dizzy if you move it around fast. The "sport auto focus" working very good! Basically you focus with your own eyes, like wen you looking something far or near. You get used with it very fast. All marine binoculars should be like that! These binoculars are really excellent for night vision. If you never use them after sun set you better buy something else like 7x30.

Rated 5 out of 5 by from A masterpiece! If you like porro prism binoculars, this is one of the two best I have seen, and I have seen and used many. The other is the Fujinon Polaris 7x50. The best use cases are for sports, birding and wildlife, including whale watching. Optically they are both excellent, but the Steiner is a third lighter, less bulky and costs a third less. Both work on the principle of large depth of field (DOF) - you adjust the left and right eye settings, and after that, you're good to see everything from about 65-70 feet to infinity in good focus. They sell it as autofocus, but it is really not autofocus - everything within the DOF is in good focus, without having to focus. In fact, there is no central focusing ring at all. The advantage of this method is, you simply hold up the binocular and see. That's it. These binoculars are very good when you're not trying to very sharply focus on one thing, but rather, see a number of things that are spread around a little, some closer to you than others. So it would be really great for sports, since you can see the entire width or length of a football field in good focus at one time, without having to constantly refocusing on one slide of the field somewhere. The weight of the binocular is not a big factor in this case, since you can keep your elbows dow and supported by your chest, so your forearm remains vertical, and your palms can simply hold up the binocular. That is very easy to do, IF you don't have to focus! So the weight is not a problem. The disadvantage of this design is, it's very impractical to use if you need to also see things that are close. If your use case requires you to see things subjects both far and closer than 65-70 years, get a binocular with a central focusing ring. This Steiner binocular has enough eye clearance to work with eyeglasses, but it may or many not work for a specific individual, depending on face / head / eye physiology. So you have to test it to see if it works for you.
