I'm a dowser too but a little skeptic to dowsers who are claiming to find those diamonds. I am relying on magnetic fields that you can not find on diamonds as we all know those diamond atoms are just carbon and electrons are almost inactive.
I understand your point bro. There are two kinds of dowsing.
One kind is totally limited to your nervous system's natural bio-reaction to preexisting magnetic fields. Working within the natural boundaries that already exist, instead of creating your own boundaries.
The other kind, which is vastly more powerful, is psychic dowsing. Using the unlimited power of the human mind to literally create your own frequencies and electromagnetic reactions.
For psychic dowsers there are no limitations on what type of object can be dowsed. Remember that every object in the universe is in a state of perpetual vibration and has its own very specific frequency to which it resonates. Therefore, any object can potentially be dowsed if the dowser is able to transmit the specific frequency for the object he is seeking. In my opinion, psychic dowsing is far superior to any treasure locating method in existence and probably always will be.
What other method gives you the ability to walk out on a plot of land, where all the signs have long since been removed, the landscape long changed, buildings now covering the targets, and locate every item within a matter of minutes? Its not really to my advantage to go deeper in to explaining this. So when it comes to supporting my claims, I'll stop here. To those who still doubt I say its totally understandable and good luck.
