Specifically engineered and built to withstand the rigors of life on the water, Nikon 7x50 OceanPro Binoculars for Marine Useproduce bright and clear images while reducing the disorientation commonly experienced when using binoculars in marine environments due to the rolling action affecting the horizon line when seen through magnified optics.

Their large objectives give the binoculars high light transmittance for enhanced low-light performance such as on cloudy or foggy days, and the large exit pupils help to further reduce the effects of rough and rolling seas while ensuring the entire scene remains visible in low light. The Porro prism optical design, combined with multi-coated optics, produces high-contrast images with true color representation and a rich depth of field that allows you to more easily discern the relative distances between objects in the field of view.

To hold up to the salt water and spray, the housing is made of corrosion- and impact-resistant polycarbonate, with rubber armoring on the exterior to provide protection against drops and impacts as well as a slip-resistant grip in cold or wet conditions. The optical tubes are nitrogen filled for fogproof performance, especially when moving between extreme temperature variations. They are waterproof to 3.3 feet for up to 5 minutes, and if they should go overboard, a high-visibility floating neck strap is included, so you'll be able to fish them out of the water in time.

• Moderate 7x magnification helps to produce a wide exit pupil for enhanced low-light use and easier viewing on rough or rolling seas
• Large 50mm objective lenses boost light-gathering ability for brighter views in challenging conditions such as at dawn and dusk or in heavy fog
• Traditional Porro prism light path presents a rich depth of field to more easily discern the relative position of objects within the field of view
• BAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortion
• Anti-reflection multi-coated optics improve light transmission for brighter high-contrast images
• Generous 378' field of view at 1000 yards

• Large slip-resistant center focusing knob is easy to manipulate in cold or wet conditions or while wearing gloves
• Fold-down rubber eyecups contour to the eye socket to block peripheral light from affecting the view
• Right-eye dioptric correction allows users to compensate for optical prescriptions for sharper views
• 56-72mm interpupillary adjustment range
• Tripod mountable with optional adapter
• Long 22.7mm eye relief allows the optic to be held away from the face and prevent accidental impacts on rough seas, and to make viewing more comfortable with reduced eyestrain
• Wide 7.1mm exit pupil allows users to enjoy the entire view without vignetting, even on rough seas

• Corrosion- and impact-resistant polycarbonate chassis
• Protective rubber armoring provides a slip-resistant grip, especially in cold and wet conditions
• Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions
• O-ring sealed, submersible to a depth of 3.3' (1m) for 5 minutes
• Includes high-visibility floating neck strap
• Tethered objective lens caps and ocular rainguard to avoid losing them during observation sessions

Related Questions and Answers

Q: 1. What is the eye relief for these bino's?

A: Unfortunately the eye relief for the Konus 7x50 Sporty Binocular has not yet been published.

Q: 2. Do you know where these binoculars are made?

A: They are made in China.

Q: 3. Is the compass visible in the dark/ at night?

A: Yes, that's what illuminated means.

Q: 4. Is a Nikon carrying case included ?

A: Yes it comes with a case. When shopping our site you can always see what is included with an item by viewing the overview tab and finding the “In the Box” listing located on the right hand side of our web page. The case is listed there.

Q: 5. Will these work in the Southern Hemisphere ?

A: No and I forgot about that the _vertical_ component of the Earth's magnetic field tilts the disc/needle opposite ways in the North and South, so a weight is needed. With a normal compass you can sometimes tilt it to compensate, but with this you can't do that.I lost a huge chunk of cost savings getting it adjusted for Ausie...it cost me IIRC about $120+ at The Aust branch, with post.Nick

Q: 6. Where is this binoculars made in?

A: They are made in China.

Q: 7. Are these stabilizing binoculars ?

A: No.

Q: 8. Why do specs of the Nikon 7x50 OceanPro Binoculars show the need for batteries?

A: I have notified the B&H web content team. No batteries required for this model only the model with a digital compass.

Q: 9. Is the internal rangefinder visible at all times? Can this binocular be use for astronomy too?

A: The Barska 7x50 WP Battalion Binocular does not have an illuminated rangefinder so it would be difficult to view in low light. They can be used for astronomy too but I would recommend using binoculars that do not have a rangefinder, but ones with more magnification and/or a larger objective lens diameter.

Q: 10. It has individual eye focusing, but is it what is commonly referred to as insta-focus, ie always in focus at nearly any distance once each eye is focused?

A: I believe so. Gift for my husband who is very particular. He loves them!!GREAT purchase.Ruth
