Here's the response I received from one of the owners of Maven:
Tim, thanks for reaching out. All three of the operating Owners used to work for Brunton and we were heavily involved with the product development of their top of the line optics. The units we are producing now out perform those in all categories, primarily due to advancements in technology over the years since the Epoch and Eterna lines were developed.
As far as where to demo them, you have 2 real options.
One: Wind River Outdoors in Lander WY is our sole retail store carrying our binoculars. We operate on a direct-to-consumer price structure, allowing us to make optics that compete with the German and Austrian brands but at about half the price. We chose this one store so that locals could go there instead of come by our warehouse, which is not set up for retail sales.
Two: You can try a demo unit from us. We charge a deposit for a lightly used bino ($800 for an 10X42), you use/test/play then you return it (using the included shipping label) and we refund your deposit.
Let me know if you need any more info.
