it took a little time. I nursed myself onto it😂. Get another line board and take the lines off of half of the board. You can still use two of the three lights for fog and have lines on about two lights. This way you can adjust the fog for the close and long views. When you are unsure of a feature you can page back and forth to the lines to see it how your mind is used to seeing it and learn the differences. I find myself using fog way more than lines now. I can see more of the fine details in the dent with fog. I do check at the end with lines at times still. It can keep me in check making sure I didn’t miss anything. First getting into fog, I found it easier to push, but I found lines were easier for knocking down. I think because it was easier to see the lines slightly move when knocking down and I couldn’t tell as much in the fog. It was harder for me to gauge how much force to use when tapping down, but after awhile I figured it out. Hope this helps.👍
