I believe there is a slight possibility that I have a bad coil on my Nox. I get good depth but my recovery speed is not good. I was wondering if anyone here can do the down the barrel nail test on a penny like in my video and see if you get it better than my machine.
Here is the video in case you haven't seen it.
