So what is the impedance of a human's skin? Why can they feel what we can't?
When I first set the level, it was 20 but we were inside where it is very dry. Outside, 20 will send her yelping for cover, i.e. behind me. So, her working level outside is much, much lower than inside, and I'm assuming due to the increased moisture.
Now I'm wondering how that feels on her at zero if she can feel what we can't. Obviously, we can't go by what it feels like to us if it's amplified for them.
