Detailed Review and Analysis

Sturdy Construction

Maven builds these binoculars with a lightweight magnesium body and rubber armor so that you can feel secure and comfortable when holding them. The eyepieces also have rubber coatings for additional protection during falls.

Produce bright images

These Maven B2 binoculars optimize the Abbe-Koenig Roof Prisms instead of the Schmidt-Pechan used in most other roof binoculars. This former design is impressive with 100% internal light transmission. That is the biggest bonus when it comes to image brightness and contrast.

Plus the ED glass, these binoculars can perform as well as other competitors with lower magnification in high and low ambient light. Only in twilight that the 8x performance is slightly better.

Easy focusing

The positive turn in the focus dial allows you to know exactly where your focus setting is. At no time will you lose your focus. That is superior to other cheaper products with loose knob, which makes you lose focus quite often. 

Incredible minimum focus range

It is high-promising for 11x binoculars like Maven B2 11×45 to have a 4.9ft minimal focus range. Combined with their powerful magnification, these binoculars are ideal for both short and long-range observation.


The body is fully sealed for water protection. This pair of binoculars achieve the IPX7 standard, tested in 30 minutes under 1 meter of water. They are fogproof, too, thanks to the Nitrogen gas-filled.

Weak points 


These binoculars are heavier than other standard binoculars out there. If you are looking for compact binoculars to take on the go, these Maven B2 might not be your perfect choice. However, this is not a big issue for most users as the added weight is not significant.

No carrying case

Unlike other products, the Maven package does not include any carrying case. For some people, a case is an important accessory to protect their binoculars, especially for high-end brands like Maven. Nonetheless, the lack of a protective case means you save a few dollars; and later, you can easily purchase one if you need.

Maven B2 11×45 vs. Vortex Razor UHD 10×42

To help you have a comprehensive understanding, we are trying to compare the Maven 11×45 with some binoculars of the same size. But it is difficult to find anything having the same “out of normal” size as Maven binoculars. Therefore, we decide to choose the standard size – the Vortex Razor UHD 10×42 binoculars.

FactorsMaven B2 11×45Vortex Razor UHD 10×42

That is an equal battle; the results are so close. Both are great binoculars, but the Maven outweighs them in terms of clarity, brightness, and quality, thanks to the Abbe-Koenig roof design and phase correction coatings. You get the crystal clear images and have almost no issues with the chromatic aberration at all.

The Vortex’s performance is impressive, too. Their FOV and minimum focus distance are impressive at 346ft and 3.3ft, respectively. However, it is incomparable with the Maven as they are not the same size. Vortex Razor UHD binoculars are lightweight with magnesium chassis and rubber armor and come with a sturdy harness to take them along on hunting trips.
