Let customers speak for us
from 18 reviewsThis is my second Maven, and their binoculars are everything they say they are on the advert: Exceptionally clear, bright high contrast image with excellent colour fidelity. These B.3's are edge to edge sharp optically and built like a tank. It's hard to look away from the Maven brand for small roof prism bino's now because they have everything i need.
Love it - used for target archery
Quick and easy way to set up phone for talking photos through binoculars
So easy to focus and clarity is great even at 50m plus.
I'm an archer and have used and borrowed various binoculars from £1200 being the most expensive, these at a quarter the price in my opinion do exactly the same job, i would normally stay away from reviews that say "great for the price" because this normally means they are crap, the longest distance i would normally use these binoculars is 50m and can easily identify the arrow I'm shooting amongst 24 arrows shot. would highly recommend these binos.
Good in lower light
Took a while to get used to
A replacement for 40 year old binoculars
Price was excellent
Enhanced my birdwatching experience no end
For the price we payed... This is definitely an excellent quality/product compromise
Very happy with it.
Thank to the team on the bird fair!

Excellent value for money.
Recently upgraded from a budget pair of binos to these for my job, they are fantastic and allow me to pick out finer details to accurately ID wildlife seamlessly!
Crisp, bright view. Firm, accurate focusing ring enabling fine adjustment. Smart, compact design, great for traveling. Haven't had much field testing yet but it will soon make it's debut in New Guinea.
These are amazing binoculars esp given the price for this starter type model. Quality lens crystal clear. So pleased with this purchase.
The clarity and brightness of the glass is incredible, even in fading light! Focusing is super quick and extremely accurate. Eye-cup extension with positive clicks are extremely comfortable even after several hours of use. The grip is extremely comfortable with a well-balanced weight. The C.1’s, look premium, with an ergonomic appearance without being overstated. These Binos are definitely up there with the best and certainly out-class the mid-range competition. They are an excellent price without breaking the bank, delivering exceptional quality. Well done to the Maven team!
Great details, good at dusk
great bit of kit for the money
As good as MY LEICA
