The new PROSTAFF 3S binocular lives up to its namesake with bright, multicoated optics, wide field of view, long eye relief and waterproof/fogproof performance. Notably lightweight and compact, the PROSTAFF 3S is a standout binocular for those looking for rugged-yet-portable optics worthy of any adventure. Features an optical system created from lead-and-arsenic-free Eco-Glass. Multilayer coatings, which provide high light transmittance across the entire visible light spectrum, are applied for bright images.High-reflectivity silver-alloy mirror coating applied on the mirror surfaces of the prisms for a bright and clear view.
Optics Designed for Brighter Views
ProStaff 3s features an optical system created from lead-and-arsenic-free Eco-Glass. Multilayer coatings, which provide high light transmittance across the entire visible light spectrum, are applied for bright images. High-reflectivity silver-alloy mirror coating applied on the mirror surfaces of the prisms for a bright and clear view.
Long Eye Relief
Nikon has manufactured the PROSTAFF 3S binoculars, as well as many other of its optics, with a high-eyepoint design for long eye relief without vignetting. This provides a clear field of view for everyone, even when the user is wearing eyeglasses.
Rubber-Armored Design
ProStaff 3s has a rugged rubber-armored coating to provide a non-slip grip, even in the wettest conditions.
MAIN FEATURES
- 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
- 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 multi-coated 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
- 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
