Magnified optics are always helpful for any firearm enthusiast. Whether it is for hunting or target shooting, being able to see further than our Mk1 Eyeballs is helpful. While I have used binoculars in the past, I do not own a pair. I have gotten by with spotting scopes or using my scopes to glass down range. So the Maven B.6 12×50 were a pleasant surprise. It is certainly a phenomenal pair of binoculars so let’s dive in and see what makes it so good.

Maven B.6 12×50
The Maven B.6 came in an interesting package. It looks like recycled cardboard used for eggs with a slip cover.
Those two circles are tabs that hold the lid in place. Push them in to lift the lid.
Underneath the lid is another layer of recycled cardboard with an envelope that holds the cleaning cloth and instructions.
Remove that layer and the Maven B.6 binos are in a microfiber cloth bag similar to the lens cleaning cloth material.
Other than aesthetics, the Maven B.6 binos are like any regular binoculars. It has flip covers for the objective lenses and a slip-on cover for the eyepieces. One side of the eyepiece cover is looped over the neck strap.
The neck strap loops are metal.
The focus adjustment knob is machined metal and has aggressive knurling so even with wet hands you will not slip trying to adjust focus. The focus knob has very little resistance. I was impressed by how easy it was to adjust with just a single finger. It felt effortless.
At the front of the bridge is that circle medallion. Unscrew it to uncover the tripod adapter hole.

How Does It Look?
While it is not apparent in the photo above, the air is full of smoke from a nearby wildfire. So the picture through the Maven B.6, below, is hazy looking due to the smoke.
That dam is 2.43 miles away.
Here are some more practical distances at the range.
Low Light Transmission Test With Night Vision
Maven makes this claim on their website:
The B.6 is one of our brightest mid-sized binoculars. Additionally, with one of the most modern optical systems on the market, this purpose-built binocular is designed to maximize optical light-gathering properties, a vital feature for enhanced glassing during those low-light periods.
So I figured a good test would be using these binoculars with night vision. I was not disappointed.
All I had to do was put the Maven B.6 binos in front of my night vision goggles and I could easily see over 100 yards away.
I used the Maven B.6 with my SiOnyx Aurora Pro and was surprised how well it works in urban environments with a decent amount of ambient light.
Final Thoughts On The Maven B.6 12×50 Binos
As mentioned earlier, I have only used my friends’ binoculars in the past so I do not have extensive experience with them. That being said, I did find these Maven B.6 binoculars to be fantastic. The image clarity was great and the low light transmission is phenomenal.
Maven charges $1,000 for the B.6 and that is for either their 10×50 or this 12×50 they sent in for review. At first, I thought that was expensive but when I compare it to other binoculars it is not that bad. The Vortex Razon HD 12×50 is a bit more expensive at $1499.99 and weighs 0.5 lbs more than the Maven B.6. This makes me think that the Maven B.6 is a better value.
