Do you run another health related channel? You look familiar! I always go out on spots I've hammered, when it recently has rained. It's almost always a few new signals that pops up!
You should use a towel or other method to hold the dirt not so messy you need to work on your plugs and be more professional especially on private property. Digging holes like that in a public park will get detecting banned. You seem like a nice guy who loves to detect live and learn peace..
You seem like a nice guy, but I'm not sure you're suited to "teach" people how to detect, seeing as how poor your retrieval methods are (lawn looks bad). You swing too fast too - you're probably missing some good stuff.
