Nobody, not even the legendary Edgar Cayce, was right 100% of the time. He is meant to have been the greatest psychic of the 20th century. He went bankrupt on dowsing for oil in Texas! I believe Marie Diamond herself probably does not get the right answer all the time with dowsing.
Kinesiology is different, so I use it to double check my dowsing or viceversa. I don't claim that in this way I will get it right all the time. From time to time I get tested by my kinesiologist, so I like to self test at times (NB I live alone and do not have friends to do muscle testing with me).
Also the Trutester is cheap and easy to carry around.
