Size Of Pendulum

Hello,

Does the size of the pendulum have an influence about the power of it?
Big pendulum BIG power - small pendulum LESSER power?

I like the Josef Baj pendulums and I have the feeling that they are the best on the market, is that correct?

I have read that the Baj pendulums are programmed during production, how this can be done and what they are programming?

Can you suggest me literature about TELE-healing and map dowsing, in which I am most interested?

Thanks in advance for answering my questions.
Kindest regards
Peter
