Hi Theseus,
There seems to be a lot of confusion about the Rangertell Examiner. We have Mike(Mont)'s idea of how it should be used, and we have the skeptical viewpoint, and the LRL proponent viewpoint with a lot of different ideas mixing together here. I will try to clear up the confusion by separating the manufacturers concept from all the other ideas we are reading here.
I studied the manual to find exactly how the manufacturer says this LRL works. I find the inventors publish definite descriptions of how it works, as well as definite methods that should be used when operating the Examiner.
To start with, it is not possible to follow the methods the manufacturer specifies if I am using the methods Mike(Mont) says are required. I can use one method or the other, but not both at the same time. I will perform Mike(Mont)'s method after I have completed the manufacturer's techniques in the interest of making a fair test for the manufacturer.
Paraphrasing what I read in the manual, I can explain how the Rangertell factory says it works:
The manual describes the Examiner as an electronic device, not a dowsing device. From what they say it is basically a kind of MFD that is much more precise than other MFDs on the market. The manual states that the target materials you are searching for have their own specific frequencies, and the coil antenna within the Examiner can amplify this frequency once it detects it. The coil antenna within the examiner will detect the target frequency because you set this frequency by entering a number in the calculator. The calculator frequency is then coupled to the antenna within the Examiner by magnetic induction, which transfers this frequency to the antenna circuitry.
The manual goes on to explain how the coils inside the Examiner are sensitive to similar vibrations as the target material, and will resonate when you have the correct numbers for the target entered into the calculator. They also explain the importance of adjusting the tuning dial and setting the antenna length when tuning the Examiner. They caution to not change anything such as removing or adding jewelry, coins, or mobile phones in your pocket after the Examiner has been tuned, because this can degrade the tuning you had arrived at and will require you to tune it again. (I suppose you are best to remove loose change and jewelry before tuning the examiner if you don't want to deal with this problem). Once the Examiner is tuned, magnetic laws govern the disposition of the Examiner to align with the target.
The manual says that a dowser may be able to locate treasures using bent wires, but not nearly as well as with the Examiner. The reason is because the bent wires are not tuned. They pick up all frequencies, similar to an un-tuned broadband receiver that picks up all RF at the same time, while the Examiner is more similar to a finely tuned radio that picks up only one signal and amplifies it. The result is the Examiner will find the target when a dowser cannot. I can quote: "The frequency that the Examiner processes is so fine you cannot possibly go wrong, even if standard L rods refuse to move for you which is a way".
Another thing that should be mentioned is this is not the average MFD according to the manual. The adjustment dial on top can be adjusted to be responsive to different size targets. That is to say, you can tune it to find jewelry stores while ignoring a ring on the ground. Or you can tune it to ignore Jewelry stores and only see ring-sized gold. The buttons pressed on the calculator are also used for selecting sizes and shapes of targets in conjunction with the dial on top. These are the ways the examiner can ignore micro gold that can confuse other MFD users.
Having said all that, I have hopefully given you and others a clearer idea what the Rangertell factory manual says about the Examiner. From what I have discerned they are describing it as an electronic locator which uses magnetic induction to transfer electronic pulses from the calculator to circuitry inside the Examiner. Then the circuitry will begin resonating at an exact frequency as a target you have adjusted it for, and magnetic laws cause the antenna to swing toward the target.
As you can see, the manual describes the Examiner as an electronic machine, not a dowsing machine. The Rangertell manual makes the distinction to show how the electronics will locate treasures that dowsers can miss. But it does seem to use the same kind of "signals" that dowsers claim to use. What is different is they use electronic means to tune these signals. And the operator's body is part of this electronic circuit along with the calculator on top. The manual also makes mention that solar interference can be annoying, but usually does not stop the Examiner from locating a target.
When I am able to make some field tests, we can check to see how well all this works. So far I have made a test to see if I can find any inductive signals coming from the calculator. I found I could pick up a series of pulses when placing a small coil at the back side of the calculator. These pulses could be measured until I moved the coil about 3 cm away from the calculator. I am sure I could detect the pulses farther if I used a more sensitive instrument, but detecting the pulses with a coil confirmed it is possible to send a pulse signal from the calculator inductively into the enclosure of the Examiner. I don't know about any of the other things like resonant frequencies or magnetic laws causing the antenna to swing, but inductive coupling is possible.
Best wishes,
J_P
