The only experience I have with one rod has been some testing here at home. I could pick up the signal but found that I could follow it and mark the spot more accurate with two rods. For map dowsing I use a pendulum. I first read the Dowsers Oath and then I Question the whole map, photo etc. I then divide the map into 4 parts and start to eliminate areas. I keep dividing the areas where I get hits until I have it down to a small area. Here is the Dowsers Oath that I read…
May I, can I, should I, ESTABLISH, CHANGE OR ADD Dowsing Conditions and Agreements or Programs which will be continually in effect until changed by me.
"Primary Program is to be continually in effect until I choose to make changes.
Covering the overall primary controls, limits, agreements and dowsing responses.
The Purpose is to determine amounts, effects, conditions, circumstances, influences, times, measurements, distances, numbers, percentages and other requested areas.
Dowsing Communications to be inter- cooperative and restricted to: the Overall Universal Superconscious, my Superconscious, my Higher Self and their approved Spirit Guides/Guardian Angels, and others of their choice, my Mind Systems, my Subconscious and its related systems. This is to cause me no harm, discomfort or loss of energy, either physically or spirituality.
Influences such as misleading thoughts, imaging, wishes, or any other conditions from any source, physical or non- physical, including my own or other persons, entities or mind systems of any kind, are not to affect me adversely or cause incorrect dowsing answers.
Time as related to dowsing is to be in my time unless other wise requested.
Answers are to be selected from all available knowledge and information sources.
The Method of Answering by the pendulum or any dowsing systems is to be: General, swinging or moving to "yes", "no" or other information, indicating the most appropriate answer for the question asked. Clockwise spin is for searching or other agreed-on systems.
Temporary Changes may be made by me while dowsing, reverting back after use.
Program Changes like adding, deleting or changing may be made by me, but only by using a three step system of my choice. End of program."
"May 1. Can 1, Should I Program, is to become a working part of all my Dowsing Programs, and be continually in effect until I choose to make changes. When used in reference to dowsing questions, the May 1, Can 1, Should 1, is to have the following meaning:
May I is to mean: Do I have appropriate permission?
Can I means: Do I have the ability to successfully dowse in this area and am I ready?
Should I means: Considering all aspects related to this situation would it be appropriate, proper and suitable to dowse in this area?
"Map Dowsing Program is to become part of and work with all my programs or agreements, and to be in effect until I choose to make changes. When using a map or drawing, some type of dowsing device, and with or without an additional pointer or straight edge, the dowsing system is to indicate when the pointer, straight edge or dowsing device is indicating the present map represented location of the object, subject or target specified by the dowser. End of Program., thank you"
