With a powerful magnification and a relatively compact design, Nikon's 10x42 ProStaff 3S Binoculars give users the ability to discern details at distance without weighing them down.

These binoculars feature silver-alloy-coated roof prisms and anti-reflection multicoated optics that produce bright and clear high-contrast images with true color rendition across the spacious and wide field of view. The 42mm objectives boost their light-gathering ability to improve views in challenging light such as at dawn and dusk or in foggy and cloudy weather without the bulk and weight of larger-objective models. Their wide apparent angle of view helps to mitigate the appearance of visible hand shake that is often associated with holding powerful optics such as this and minimizes movement of the horizon line on rough or rolling seas to limit disorientation when using them on a boat. The combination of prisms, optical coatings, wide field of view, and comfortable eye relief allow users to enjoy a comfortable and immersive observational experience in most lighting conditions.

Complementing the optical performance are construction details that make these binoculars durable and comfortable to use. They have a lightweight and corrosion-resistant reinforced polycarbonate resin chassis and are protected by black rubberized armor that is accented with textured palm pads to give them a secure non-slip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and submersible, as well as resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A tethered one-piece ocular rainguard covers the eyecups as the binoculars hang around the neck and prevents rain and spraying water from filling them, and the objective lens caps can clip onto the neck strap to keep them safe from blowing overboard or being lost on the forest floor.

Whether you're hunting or birding, boating or watching your favorite team, these ProStaff optics will quickly become indispensable for all your outdoor activities.

Optical Performance
  • High 10x magnification brings distant objects in close for detailed observations
  • 42mm objective lenses improve light-gathering ability without adding excessive bulk or weight
  • Roof prism light path ensures optical tubes remain thin for a compact form factor
  • Anti-reflection multicoated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity
  • High-reflectivity silver-alloy prism coatings reduce internal diffraction to further improve light transmission and contrast
  • Wide 63° apparent angle of view helps to minimize the appearance of visible hand shake that is common when holding high-power optics such as this
  • 367' field of view at 1000 yards
Use and Handling
  • Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism
  • Large slip center focus wheel allows for precise focus control, even while wearing gloves
  • Right eye dioptric adjustment collar helps to compensate for individual eye prescription
  • Twist-up/click-stop rubber eyecups for use with or without eyewear
  • 15.7mm eye relief helps to reduce eyestrain and improves viewing comfort
  • Comfortable 4.2mm exit pupil will cover most pupils as they open and dilate in low light to keep the full scene in view
Construction Details
  • Environmentally friendly Eco-Glass is made without lead or arsenic
  • Lightweight and durable fiberglass-reinforced polycarbonate chassis
  • Chassis material is temperature resistant, preventing the expansion and contraction that is common with metal, which can cause the optical components to move out of alignment over time and prevent sharp focus
  • Textured protective rubber armoring provides a slip-resistant grip, especially in cold and wet weather
  • Textured, ergonomically placed palm pads improve grip stability and comfort
  • Nitrogen-filled and O-ring sealed to be waterproof and submersible to a depth of 3.3' (1m) for up to 10 minutes and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
  • One-piece tethered ocular rainguard protects eyecups from water pooling in them from rain or spraying water when hanging from the neck
  • Objective lens caps can be clipped to neck strap to avoid losing them during observation sessions
  • Packed in an attractive box
  • Weight: 20 ounces

These were a mothers day gift from me and my father. These nikon binoculars are high quality and very good for the price and we all were very pleased and my mother was impressed with the quality of image looking thru them.i beleive the quality of the optics is much more important than the power or magnification. Nikon is my #1 go to brand in binculars now across all the price ranges especially the 100-400 dollar range. This pair of prostaff are fogproof and fully multicoated lenses and i can tell what a difference those features make. I have 3 pair myself which are other quality well known brands in the 100-350 dollar range and imo the nikons are superior. I would definitely recommend any nikon binoculars that r fogproof with fully/multicoated lenses.

Binoculars do the job.

Based on the specs and reviews, I narrowed my choice to the Nikon ProStaff and one other competing brand. The sale by B&H clinched it. The resolution and clarity of the Nikon 3S binoculars at 10 X 42, and their light weight, made me very happy with my purchase. I use them regularly to observe wild life in and around the lake behind my house.

great binos

What is the main difference between the Nikon 10 x42 ProStaff 3S and 7S binoculars?
Asked by: Cristina
The 3s has Silver-Coated Roof Prisms while the 7s has Phase-Corrected Compact Roof Prisms. The 7s has Highly Reflective Mirror Prism Coatings while the 3s does not. And the 3s has Multi-Coated Optics while the 7s has Fully Multi-Coated Optics Multi-coated means at least one of the major optical elements in a fully-coated binocular has multiple coatings of anti-reflective compounds on at least one surface. Fully multicoated means all glass surfaces have multiple coatings and it is the best kind, resulting in light transmission of 90-95% for bright, sharp and contrast images.

How well do these bins work with eyeglasses? I wear bifocals.
Asked by: Dawn
I wear regular glasses and they are good when there is not much peripheral light that can hit your eye when you are looking into the eyepieces. Eye relief is good enough. The apparent field of view is very large so it is a bit difficult to see the very edges when viewing with glasses.
