Carson MonoZoom Reviews

Solid Monocular

By Kyle
Rated 5 out of 5

Bought this for various magnification needs, getting a better look across a lake, closer, but still distant, bird watching; and just general pirates-spy-glass-things. Great device overall, I appreciate the carrying pouch, the included lanyard is a bit much for me, but still a nice touch. The image quality has been dry crisp, and the device is easy to operate; this puppy checks every box
