The scalar field is unaffected by the metal, only the link cable and scalar unit can be affected by the metal. The metal within the body has no effect on the scalar field, it won’t interfer with the scalar field.
The jewelry is fine and it is ok to leave on during the treatment.
It does not affect the field, or the effect is so small to make it negligible.

As I am a total beginner, I would like to know if there is a tutorial for the initial operation of a Spooky2 Scalar equipment.
Dear Hermann, here is a Spooky2 Scalar Training Course for scalar new users: https://www.spooky2scalar.com/spooky2-scalar-training-course/
Would someone in a wheel chair with large amounts of metals from the metal frame of the wheel chair be a problem for the Spooky2 Scalar machine?
Dear disciplineab, what you need to care about is to keep your linkcable and two scalar units away from metal. It’s ok to have metal in scalar field.
I did have some concern using Spooky Scalar after a heart attack
in Januar this year. (2019 )
A stent(metal) was inserted in the main artery.
The metal worried me,that the scalar field could cause problems.
But this statement has cleared my concern.
Should there be any additional information, please notify me
by Email. Thanks….Bodo
Dear Bodo Geissler, we’ll do that. If you have any other problems, you can ask in scalar group: https://www.facebook.com/groups/spooky2scalar/
