Features of Maven B1 42 mm ED Binoculars

Weight and Dimensions

These binoculars weigh about 29.12 oz which some people may find a bit heavier but given the metal chassis and 10x magnification, this weight is completely acceptable.  

The dimensions of the Maven B1 Binoculars are 5 x 6.2 x 2.1 inches. These mid-sized binoculars are perfect for any kind of outdoor activity. 


The Maven B1 Binoculars are ergonomically designed with robustness and durability features that will last you for more than one generation. The magnesium chassis is quite sturdy and is stronger than the plastic one.

Though this all-metal body may add up to the bulkiness, it is negotiable considering these binoculars remain quite intact to external wear and tear. 

The rubber armor is soft, textured, and provides a non-slip grip while using in any environmental conditions. There is a wide gap between the two barrels for proper gripping.

Magnification and Objective lenses

Most of the hunters prefer a magnification of about 10x which the same as Maven B1 42 mm Binoculars offer. These binoculars bring the world ten times closer to you. 

The diameter of objective lenses is 42 mm which gathers enough light to form an edge-to-edge sharp, generous depth of field, and crisp view. 

With much larger objective lenses, the binoculars often tend to get bulky.

So, 42 mm objective lens diameter is quite good considering the magnification and keeping these binoculars under standard mid-size value. 

The objective lenses can be used with 49 mm filters either UV filter or polarising filter for viewing in harsh situations. 

Lens coatings

The Maven B1 ED Binoculars consist of extra-low dispersion (ED) glasses to reduce chromatic aberration and restore the natural colors of the object.

The glasses are fully multi-coated at multiple layers that ensure maximum light transmission so that these binoculars deliver superior low-light performance.

The dielectric coatings reduce the loss of light due to reflection and deliver elite optics even at low lighting. 

The lenses are coated externally to make them scratch and oil resistant. 

Prism type

To reduce the size as much as possible, the Maven B1 Binoculars have roof prism construction.

The prisms are designed in Schmidt-Pechan design to enhance more than 90.99% light transmission for bright image formation even during dusk, dawn, or haze.

There are dielectric coatings on the reflective surfaces of the prisms.  

Waterproof and Fogproof

Designed with an IPX7 rating, the Maven B1 ED Binoculars are waterproof.

They are nitrogen purged to reduce the internal fogging of the lenses. The lenses are coated with hydrophobic coatings that save them from moisture, dust, and scratches.

So, you can fully trust these binoculars to render high-quality performance while using them from hot deserts to the Alaskan weather. 

Won’t matter if it’s raining or shining bright, these binos will provide you with a high-quality viewing experience without any performance drops under the weather.


The focus knob is centrally placed in the narrow bridge which is easy to access. The knob is made up of aluminum with ridges on the surface. It is easy to turn and allows smooth focusing of the objects. The distance of close focus is 6.6 feet. 

The eyecups are twistable and can be adjusted to provide an eye relief of 16 mm.

People who use glasses or elderly people can use these binoculars with maximum comfort.

You can twist the eyecups in three positions and they remain fixed in place. The eyecups are replaceable so that you can remove them whenever not in use.   

Exit Pupil

The exit pupil of the Maven B1 42 mm ED Binoculars is 4.2 mm. Eye relief is the ratio of the size of objective lenses to the magnification of the binoculars. 4.2 mm eye relief is enough to transmit enough light for forming bright images. This also helps with low-light viewing ensuring great image quality.

Field of view 

These Roof Prism binoculars have a wider field of view of 341 feet at 1000 yards. Most of the high-end binoculars fail to achieve a wide range of views but Maven B1 ED has a large field of view that will be your companion while on the field. 


The price of Maven binoculars is somewhat cheaper than other high-end binoculars from renowned companies.

Maven also supplies its products directly from the manufacturer to the buyer that cuts off the price spent in the retail market. So, you will get a good product at a relatively lower price. 

You can get the Maven B1 42 mm ED binoculars from Amazon at $950 which we agree is quite expensive. But it is much cheaper considering the high quality and performance than the same ones from other German brands. 


The accessories you will get along with the packaging are a neoprene neck strap, rubber lens caps, manual and double-layered microfiber bag.  

Additional Features

These binoculars are adaptable to tripods that reduce the fuss of holding them still during prolonged use. The single hinge of the binoculars consists of sockets for tripod adaptors.

The unconditional lifetime warranty from Maven is something you won’t get on other brands. No matter when you have bought the Maven binoculars, you can always replace and repair them.

You can also personalize your own binoculars from the official website of Maven that is  where you can choose the color of the housing or even inscribe your name on the binoculars.

Maven B1 42 mm ED Binoculars FAQ

Is the Maven B1 binocular better than the C1?

Both of the binoculars have unique features that make them better in their own place. The C1 Binoculars are much cheaper than the B1 binoculars.

Both the binoculars have similar traits like the Schmidt Pechan roof prism, ED glasses, weatherproof designs, and so on. The B1 series provide more clear and high-resolution images because of more lens elements in them. 

If you are looking for mid-range binoculars and small details are not much important for you then you can opt for the C1 series.

The Maven B1 Binoculars are the best if you are someone who doesn’t want to compromise on quality and want to spend a few extra bucks on a good pair of binoculars. 

Can Maven B1 42mm ED Binoculars be used in rainy and harsh weather?

These binoculars are made with IPX7 waterproof ratings. So be sure that they won’t be damaged even if you drop them 3 feet underwater for some minutes. Also, the nitrogen purging makes them fog proof so the weather might be foggy but your lenses will be clean. 

The hydrophobic coatings on the lenses make them water, oil, and debris resistant and the rubber armor is strong enough to provide firm gripping. There is no doubt that these binoculars will perform best in any outdoor condition. 

Why are Maven Binoculars cheaper given the same optical features as some of the pricey binoculars in the market?

Maven believes in supplying products with less marketing but with high quality. While most of the brands spend thousands of bucks in marketing and retailing, Maven supplies all its products directly from the distributor MavenBuilt to the users. 

So the hefty price of the retail market is cut off from the product making it cheaper than the high-end competitors. This helps in utilizing the profit in product development and testing them. Hence the product becomes only better and better with time.

Aren’t Maven B1 ED Binoculars heavy?

The total weight of the Maven B1 42mm ED Binoculars is 29.12 ounces. For a binocular like this having more lens groups and an all-metal frame, this weight is justifiable. The standard weight for binoculars of mid-size is 29-33 oz.

The quality would have been decreased drastically if they had tried to decrease the weight of these binoculars. Hence the weight is slightly more than the plastic frame binoculars and is negotiable as compared to the performance. 

Why should you choose Maven B1 Binoculars?

If you are someone who is brand conscious and prefers some specific brands, then it’s completely up to you. But when you are getting the same quality and attributes for a relatively low price value then it is unquestionable that you should choose Maven. 

We are not saying that these binoculars are the best than other German brands but if the brand is not much of a concern to you and wants a good pair of binoculars at a comparatively lower price, Maven B1 ED Binoculars should definitely be your go-to options.
