The monocular will allow you to see in complete darkness using the IR light source. I live in a rural area and light gathering ability of the device is OK. You can see better at night with the device but keep in mind the image is Gen 1. I was prepared to return the device if I felt that the image was unusable but that was not the case. I can see my dog at night using the device whereas he is undetectable to the unaided eye. I think the monocular is worth the money...again it is a Gen 1 device and performs as expected.
Pros: Allows you to see in the dark
Cons: Image is Generation 1
