Pendulum dowsing and radiesthesia

What it is

Dowsing uses a hand-held instrument (most often a pendulum, a small weight on a thread or chain, or rods) whose movements are read as answers, usually yes or no, to questions the dowser asks. The BSD describes dowsing as "often associated with locating underground water, minerals, or energy…

Format

• Who practises: BSD members, affiliated local groups, independent practitioners, and some complementary therapists who combine dowsing with other methods.
• This work is not a separate course of therapy. It is woven into ordinary assessment and treatment and revisited when health decisions come up.

Who practises it, and how they are trained or regulated

• What a client experiences: The client either consults a dowser or learns to dowse for themselves. BSD-listed professionals are approved after they have "provided references from clients or patients or such other evidence as the Council of the Society deemed appropriate". Their listings describe services such as health and personal development, geopathic and EMF stress, earth energies, space clearing, spirit release…
• Training: The BSD runs a training programme and keeps a register of approved tutors and professional dowsers. Its courses include foundation courses and an introductory day on dowsing for health (October 2026). A "Code of Ethics for Tutors" and a "Code of Professional Ethics" are named on the BSD site, but their text is. The approved-professionals page publishes no complaints procedure and no medical disclaimer.
• Regulation, UK (one line): Dowsers are not statutorily regulated. Advertising is covered by the CAP Code: claims to diagnose or treat a medical condition need a suitably qualified advertiser (rule 12.2) and robust evidence (rule 12.1).

Evidence status, as the guide reports it

• Evidence status (one line): Controlled tests have not shown dowsing to detect anything beyond chance. In a government-funded Munich test of about 500 dowsers in the 1980s, results were consistent with chance.

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• How do you and the practitioner understand what is happening, in spiritual or cultural terms? Is that a source of comfort, worry, or both?
• Does it use a device, heat, cold, water or a physical procedure? Has a medical professional checked that it is safe for you?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• A rupture in the relationship after reporting (see section 5).
• Your own pull to collude or to debunk. It is working when the client experiences you as neither selling nor mocking.
• Loyalty conflicts. Withdrawal from family. Escalating spending. It is working when the client keeps the parts that help and feels free to question the parts that don't.
• Distress when a decision is made without the pendulum. The client experiencing it as a threat to their spiritual practice; if so, return to 4.10. It is working when the client can make small…
• Embarrassment or guardedness, which suggests the client expects judgement, so slow down and normalise. Any use for medical diagnosis, for medicines or for children. It is working when the client…

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
