Maven Optics | B3 Review
By Brock Akers, Rokslide Moderator
Measuring in at under 5 inches long and weighing a mere 16.25 oz. These are the ounce counters dream binocular. Built using the Schmidt-Pechan prism, Maven was able to get these extremely compact. Perfect for a hunting scenario where big binoculars aren’t as important. Such as a hunt in thick timber or if you are packing a big spotting scope.

Once out of the package, the construction and attention to details on these 8×30’s really jumped out at me. Built out of a polymer frame, They felt rock solid. The focus wheel is very smooth with virtually zero slop. I liked the included harness attachment clips. I followed the instructions for installation and it was very easy. Adding the objective lens protectors is a must. Cheap insurance to prevent scratching and wearing off of the lens coating. With 99% light transfusion, they have no effect on performance and are available for a very affordable price. A quick visit to yielded an impressive spec sheet with more information than expected. A lot of questions were answered there with ease.

Light testing
I took these out to test their performance with fading light. This might be the conventional way to test an optics performance but I felt it was the most realistic scenario I could simulate aside from sitting on the mountain looking at an animal. The sunset was at 4:59 P.M. on sunny day. I picked two places I would look every 5 minutes. A tree line that was 400 yards away and few black and brown cows in the neighbors pasture 150 yards away. Here are my notes:
5:05 P.M. – Full light, can see very well
5:10 P.M. – Full light, can see very well
5:15 P.M. – Notice light fading with naked eye, tree line and cows still very visible
5:20 P.M. – I can still see the cows. Easily could spot a deer or elk along tree line if they were moving.
5:25 P.M. – Tree line still visible, saw a flock of ducks fly through my FOV. Picked the white wings out easily.
5:30 P.M. – Tough to see darker colors now. Light colors only (tan elk body moving against the dark tree line for example). Black and brown cows hard to pick out.
5:35 P.M. – I would be heading back to my tent now.
Chromatic Aberration
On a recent coyote hunting trip to the deserts of Washington I was able to detect some chromatic aberration. Although it was there, it wasn’t bad. I had to really look for it. The conditions were overcast and dry. I could only see it when I was looking at a tree or sage brush with the bright white sky as a backdrop. Built using ED glass, the amount of CA you see, is perfectly acceptable for hunting situations in my opinion. Spending hours behind these would be no problem.
Maven will be a player in the optics game for some time to come. With their optic quality and custom build option on their website, they are sure to be a popular choice among the growing crowd of hunters. With an unconditional lifetime transferrable warranty behind them and a price point starting at $500, these will be a great purchase in the upper middle class range for optics. They have found a spot in my bino harness and on my tripod for the upcoming season.

Brock Akers
Growing up in hunting family, it was expected that Brock would take to hunting at an early age. Spending most of his childhood in the duck blind with his Dad, he was eager to take part in the harvest himself. Passing his hunter safety course at the age of 9 and taking his first buck that fall was all it took for him to be hooked. Between deer camp each October & weekend trips to eastern Washington waterfowl hunting, time was pretty much consumed. However education was stressed by his parents as the number one priority. He graduated from Renton Technical College in 2008 with a certification in Engineering Design & Technology and has been working in the design/drafting field since then. His current job allows for flexible dates which in turn means a generous hunting season. Aside from hunting in his home state of Washington, Brock also hunts a variety of species each year in Idaho & Montana while building points in several other states. Most of his hunting is done in the remote backcountry. This type of hunting really makes him appreciate the outdoors for what they are. You can find and follow along with him on Facebook & Instagram.
