Brunton Echo Pocket Scope 7X18 mm
The monocular is ultra-light and compact so I don't even notice it in my backpack or pocket. As a consequence, I carry it far more often than I was carrying my compact binoculars.
However, because the unit is so light, it jiggles a lot which makes it desirable to use a support such as a tree or post. In addition, the width of field and depth of focus are limited, making it hard to locate and focus on a target, e.g., a raptor sitting on a transmission tower.
It is a decent value at its price point. I'm glad I have it, and would buy it again even knowing its limitations, but would advise a would-be purchaser to keep their expectations modest.
I bought these to carry in my Polaris RZR for those times when you see something, such as an animal, and would like to get a better look. Usually when we are riding our RZR we are out just for fun, and binoculars around the neck get to be a pain. I attached the carrying case for the pocket scope to the roll cage of the RZR, and now I have ready access to it. The image is adequate (certainly not what one would get from a good pair of binoculars), and considering how little these monoculars cost, they provide a good image. If you are looking for something to throw in the glove box, pocket, backpack, or attach to the roll cage, this is just the ticket.
