American Society of Dowsers
(American Dowsing Society)
In America (United States), the "American Society of Dowsers" is the main dowsing society run by dowsers, serving American dowsers as well as international dowsers for over 45 years.
You can reach the American Society of Dowsers at http://www.dowsers.org
(remember to type .org and not .com)
Sometimes, mistakenly, people call it Society of American Dowsers or American Dowsers Society, or the American Dowsing Society. Just remember that their abbreviation is "ASD" (American Society of Dowsers), and not "Ads" nor "Sad".
Among the main dowsing services the society offers is the "The American Dowser" which is probably most sought after dowsing publication of interest to both expert dowsers as well as beginner dowsers in not just America but around the world.
The other major contribution of the American Society of Dowsers is organizing the major and largest dowsing conference in America every summer, bringing in professional dowsers and speakers to share their insights on dowsing. This dowsing event is open to anyone with an interest in dowsing, and not just expert American dowsers.
