All dowsing is first done remotely from a google map of your property.
In order to dowse your property for water, I will need an address.
I can refer you to a specific driller for Sonoma, Napa, Marin, Mendocino counties if you wish.
I can dowse any address in the world, as long as I can see it on Google map.
Please send any requests/questions to email address below, adding Dowsing in subject line.
Thank you
