Maven B.3 Binoculars Price
Maven’s price is attractive in large part because they’re a direct-to-consumer manufacturer. With no retailer markups, you get the savings advantage.
The B.3 is available in 6 x 30, 8 x 30, and 10 x 30 lens configurations with a price ranging from $525 – $575. They’re backed by a lifetime warranty.
Should You Buy Them?
I own Maven optics from both the B-series and C-series, and I heartily recommend them to anyone in the market for an upgrade. The B-series offers the highest quality, with a sharp, clear edge-to-edge picture. They use Japanese components and are assembled in Lander, Wyoming, in a facility overlooking the town, which has a fantastic view of Lander’s legendary 4th of July fireworks.
The Maven B.3 is a compact binocular suitable for a wide range of outdoor activities, including hunting, birding, and general travel. However, it’s not the most compact. That award goes to the B.7 binocular, which is my go-to when I’m traveling. The price tag is a little lower on the B.3, though, and if you don’t mind a bump in size and weight, you’ll also enjoy a bump in brightness and field of view.
The B.3 also doesn’t have the highest magnification in the B-series lineup. That goes to the B.5, which has magnification options up to 18X plus a much larger objective lens. As you would expect, they are larger, heavier, and more expensive. But if you’re stalking big game at the longest distances, you should consider them.
So where does it fit?
The B.3 is your top all-around pick if you’re looking to balance clarity, brightness, and compactness. It’s also the most affordable in the line, giving you an excellent entry point into the B-series’ quality. When you look at the price compared to what you’ll have to pay to get the same quality from other brands, you’ll be impressed.
