https://youtu.be/OToHLys8Okw Well not the best but hey only took a hour to get out it's hard to see the screen when I trying to explain how to tell nails from coins .
But If you get a bastard nail and a good nail and scan them between ferrous coin combine and 4 tone conduct you will see what I'm talking about .
Another thing I failed to mention pinpointing tight signals if you use normal it will downsize to where you want , now pinpoint sizing will down size manually and give more control of the spot you want to be looking at. To get a good look at that exact spot. sube
