Built with Superior optical design, the Prostar WP Binoculars are ideal for astronomical use with aberration-free view. It features 10x magnification, 70 mm objective lens, and 5.1° Angular Field of View adapts to any situation with the need of high precision focusing. Its high-eyepoint design gives a longer eye relief even in longer time span of use. The rubber armouring will provide secured grip and comfortable hold to avoid accidental slip. With the waterproof up to 2m/6.6 ft. (for 5 minutes) and fog-free structure, it is capable to be used at seas. The Multilayer Coated Lens guarantees the right amount of light transmittance to achieve the right glow of the object, like you looking at them with your naked eye. Prostar binoculars can be fixed to a tripod for a more stabilized view and an optional Polarising filter and horn-shaped rubber eyecup.
Porro Prism Type
Binoculars that employ a Porro prism, which was invented by Ignazio Porro in Italy. All of its reflective surfaces are completely reflective, so it loses no light and realises a bright field view.
IF (Individual Focusing)
Binoculars that have an IF (Individual Focusing) mechanism. Focus the right and left eyes separately by rotating the dioptre adjustment ring located on the eyepiece. Structurally, the design easily maintains
airtightness, making it suitable for waterproof models.
Multilayer coating is applied for increased light transmittance.
Long Eye Relief
High-eyepoint binoculars with eye relief of 15mm or longer. Eyeglass wearers can also obtain the field of view without vignetting.
Waterproof structure is employed. Nitrogen gas-filled models are resistant to fog and mould.
Astronomical observation requires a bright optical system with a large objective diameter and exit pupil. Waterproof and aberration-corrected binoculars are preferred.
Marine sports, fishing
Waterproofing and durability are essential for these activities. Enhanced brightness and a wide field of view are desirable too. Models that feature vibration reduction are favoured for on-board use.
For professional workplace usage such as sailing or maritime observation. Waterproof, large-diameter binoculars are recommended
