Overall, i'm happy with it. - Yukon NVMT 3x42 Sea Wolf Waterproof Night Vision Monocular - Multitask Night Vision Monocular 24022WP

This is a good product & I am happy with it overall. The focuser is somewhat loose & feels cheap, but the image can be focused to a sharp picture. The optics are suprisingly good. In town, with some residual light, at 100' without using the illuminator you can easily see and identify people that would otherwise be completely hidden from view.
The IR illuminator works great, almost too well. Don't expect to use the illuminator if you don't want to be seen. It is clearly visible by anyone you point it at. If you aren't going to be sneaking around it won't matter, but this would be a better product if you had the ability to run the illuminator at reduced output, or if there was an optional clip-on IR filter that blocked all visible light output. Even if they reduced IR output by 50%, it would still probably be fine.
The design of the lens cap storage slot seems somewhat clumsy & might actually increase the chance of losing the cap. I think tying a string on it, or putting it in your pocket would keep it safer. At least if you drop it you have night vision to help find it.
The NV will continue to function for several minutes after you switch it off. It can be confusing at first because the power light will be off, but it still functions.
Pros: Quality is good
Cons: IR illuminator is visible
