I'm sorry, but about a third of Edge's stuff is almost incomprehensible to me, I cant follow the grammar half the time nor make out what he's on about. Perhaps it comes with being delusional, which he more and more appears to be. "Delusional? How so?", I hear you cry. Well...
Edge has a magic stick which he believes defies all known science and can be used to detect precious metals, water and minute disturbances in electromagnetic fields, amongst other things. He can detect a few grammes of gold buried deep in sediment, or detect the minute magnetic anomaly in the earths magnetic field caused by a small lump of heavy material. Or so he claims.
In reality he cant detect large quantities of gold hidden under a cup, or indeed any metal of any value hidden under anything not transparent. As he admits himself, every test of the abilities of his magic stick have proven that it's not in any way magic, and is in all likelyhood just a stick. He refuses to accept that.
He has spent three years mining for gold using his magic stick as a guide, and in doing so has grown thinner, not richer. Anyone else in the world blessed with a true method of easily finding buried gold would be independantly wealthy in a short time. He refuses to see this, since he finds tiny quantities of gold where his magic stick tells him to dig. Admittedly he's digging in a known gold field, but it's still proof enough for him.
In short, all the evidence points to Edge being a deluded guy being led around to his detriment by his belief in the magic powers of a twig. All the evidence says it's nonsense, Edge believes it's magic. Deluded.
