Meopta - 10x42 MeoStar B1 Plus HD Binoculars

A Guide to Marine Binoculars

The Meopta 10x42 MeoStar B1 Plus HD Binoculars provide a superior viewing experience by combining well-engineered optics and a wide field of view in a lightweight and durable housing.

The extra-low dispersion (ED) fluoride glass lenses, treated with proprietary MeoBright multicoatings, and compact Schmidt-Pechan prisms deliver vivid true-color images that are bright and crisp across the entire field of view. The lenses are further treated with Meopta's proprietary MeoShield and MeoDrop exterior coatings that protect the lens surfaces from scratches and makes cleaning oils and other contaminants easy without leaving residue. These coatings ensure the lenses stay free from imperfections that can interfere with your glassing experience and let you immerse yourself in the view.

Meopta designed the binoculars with ergonomics in mind to minimize user fatigue during long observations. Its large center focusing wheel is easy to use with either hand and a locking dioptric correction dial, located on the focusing knob, ensures precise focusing even if you normally wear corrective eyeglasses. The housing is made from a lightweight and durable aluminum alloy that is center weighted by the prism design, so they sit comfortably in the hand. Protective rubber armor wraps the body and provides a slip-resistant grip, especially in cold and wet conditions. The housing is nitrogen filled and sealed to be waterproof and resistant to internal fogging in extreme conditions.

Optical Performance

Ideal for wide and open terrain where extreme long-distance observation and identification are common

High 10x power magnifies the view, allowing detailed observation of distant subjects

42mm objective lenses deliver bright views even in challenging light conditions without being too bulky or heavy

Schimdt-Pechan roof prism design allows for thinner optical tubes versus the more common Abbe-Koenig design, resulting in an easier-to-hold form factor without compromising performance

Extra-low dispersion (ED) fluoride glass objective lenses correct chromatic aberrations and fringing to deliver bright and clear high-contrast and high-resolution views with accurate color representation

Proprietary ion-assisted MeoBright multicoatings deliver 99.7% light transmission while suppressing glare

MeoShield exterior coating protects lenses from scratches or abrasions

MeoDrop lens coatings repel water and allow grease, skin oils, and surface contaminants to be removed without residue that can impair view clarity

Wide 63° apparent angle of view provides sweeping views of the terrain with reduced appearance of the distracting hand shake that is common when holding high-power optics

Generous 332-foot 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-resistant center focusing knob with ±3 dioptric correction dial is easy to manipulate in cold and wet conditions, even while wearing gloves

Locking diopter sets the desired correction against accidental adjustment

Wide 56-74mm interpupillary adjustment range

Twist-up rubber eyecups for easy use with or without eyewear

15mm eye relief reduces eyestrain during long glassing sessions

4.2mm exit pupil will cover most pupils as they open and dilate in fading light to avoid vignetting of the view

Construction Details

Lightweight and durable aluminum housing

Rubberized armor protects chassis while offering a slip-resistant grip

Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging in extreme conditions and temperatures

Tethered objective lens caps protect the lens surfaces without the fear of losing them when using the binoculars

Compact design is just 5.5" long

Weight: 33.3 ounces
