I used to live in Cornwall and several times met Hamish Miller (famous dowser who lived nearby). He got me interested in dowsing and this zome is my first attempt at "Litho-puncture" (acupuncture for the land) which I made a couple of years ago. I dowsed the energy-centre of the quinta and placed it there, as a way of honouring Mother Earth - and of helping the energy-flow to improve. This affects both underground water movement, and the vitality of plants, although I have no 'scientific' proof - but imho proof is only for superficialities.
Hamish was an amazing guy (read his obituary here: https://www.theguardian.com/theguardian/2010/feb/18/hamish-miller-obituary)
and I have a pair of dowsing-rods he made for me.
