Dell Systems Remote Sensing Geo-Surveyor

The controversy over what has become known as the MFD, or molecular frequency discriminator, continues. Electronic engineers who rely strictly on conventional physics maintain the MFD is essentially a dowsing rod because it is not based on universally accepted scientific principles. Over the last several decades another group of engineers, familiar with the principles of dowsing, have attempted to bridge the gap between standard physics and the so-called extrasensory abilities of the human mind. They believe that any substance creates a measurable electrical field that inter-reacts with the electrical magnetic fields of human cells. Since the molecular composition of substances differ, the frequencies or harmonics of their electrical fields likewise differ. The job of the MFD is to filter out the frequencies of unwanted substances, so the operator can tune in only desired substances, such as gold.

Science may never prove these theories correct, but perhaps that is unimportant. Scientists still don't know exactly what electricity is, yet their theories about the phenomenon led to many useful appliances. As development and testing proceed, MFDs may prove out the same way, for a few treasure hunters, including non-dowsers, claim some success with them. With this in mind, let's take a look at the operating principles of one of the more interesting units on the market Dell Systems Geo-Surveyor, a compact, lightweight instrument utilizing the concept of harmonic induction discrimination for medium range, sub-:surface metal and mineral exploration. The Geo-Surveyor circuits were designed by electronic engineer Vernon Rose, one of the pioneers of the molecular frequency discriminator. The circuitry in the Geo-Surveyor provides greater latitude resulting in better discrimination and a more accurate on-target signal. The Geo Surveyor also incorporates a "Magna Wave' receiver to smooth distortions of the magnetic field, providing more definable responses from the receiver antenna rods.

The small but powerful transmitter was developed to utilize the medium of soil or water to transmit and receive wavelengths for distances up to 1/2 mile horizontally or vertically. The range of the Geo-Surveyor is dependent on soil density and atmospheric conditions, however, and most practical surveys are generally conducted within a range of 100 yards. The signal is omni-directional, and the unit reflects and receives its own signals from surrounding metals or minerals.

The returning signals are received through an analyzer which rejects frequencies other than those that it is programmed to accept. The Geo-Surveyor comes factory programmed to identify and locate gold or silver, but it can be custom programmed to find more than 58 other elements.

The Geo-Surveyor is easy to operate, but efficiency of the operator is gained through practice and is the key to proper interpretation. Although training is advised when possible, it is not essential for immediate use, and the operator can become proficient through adequate practice and close attention to the operating instructions provided with the instrument.

To survey a potential site, two small ground probes are inserted in the ground. These connect: to the transmitter by virtue of color-coded positive and negative plugs that match the color-coded jacks on the face of the transmitter. A two-position switch on the transmitter face allows the operator to select the setting for either silver or gold (or the other elements that have been custom programmed). An indicator light above each setting comes on at the selected position when the unit is turned on.

Two antenna rods with telescoping shafts can be lengthened when in use and retracted for easy storage in the carrying case when not in use. The antenna rods have a single plug which connects to the belt mounted Magna Wave receiver. Power for the receiver is provided by one 9-volt battery. A battery test button on the top of the receiver can be depressed to test the battery. An LED light next to the test button will light up and an audible tone will sound to indicate battery condition. Care should be taken to prevent the antenna rods from touching together. This will rapidly deplete battery life. However, a breaker has been installed in the receiver in the event the rods are inadvertently held together while plugged into the receiver. When operating, the antenna rods should be held in a horizontal position and properly balanced. This technique will become natural with practice. The rods are made to rotate freely in the handles.

The transmitter is powered by four 'C' batteries that may be easily replaced by removal of the plastic panel cover on the rear of the transmitter. Although the four 'C" batteries will provide many hours of usable battery life, the manufacturer recommends the operator always carry an extra set of batteries, including a spare 9-volt for the receiver, whenever going out into the field.

It is important to wait three minutes after first turning on the transmitter before beginning a search pattern. This allows time for the signal to reach a target and return a signal to the receiver.

When beginning a search, the antenna rods are held by the operator, one in each hand, and are the visual indicators that identify the signal line received by the belt mounted receiver. The rods align themselves with the line of signal, remaining straight ahead when traveling parallel over the signal line or crossing when traveling perpendicular over the signal line. Following an 'S' pattern from the transmitter, back and forth over the signal line, and moving further away from the transmitter with each crossing will identify the line between the transmitter and the target, by causing the antenna rods to cross directly over the signal line on each pass. Once past the target location, the rods will cease to cross, even when passing over the direction that the signal line had taken up to the target.

Once a signal is received and the exact location identified, the operator can then adjust a rotating anomaly qualifier knob, which has been mounted on the transmitter face in order to identify the quantity of precious metal present. Turning the knob counterclockwise identifies the quantity in ounces. Turning it clockwise identifies the quantity in pounds, up to five pounds. This knob should be set at 'O' (straight up) when beginning the search process. Once a deposit or vein has been located, the quantity (weight) can be ascertained, and by approaching the target material from four different directions, it is possible to determine the size (and to some degree, the configuration) of a deposit or vein.

The electronic circuitry of the Geo Surveyor is so designed to eliminate signals from micron (flour) gold while picking up the signal from a gold nugget, even when the nugget is surrounded by flour gold.

The Geo-Surveyor is specifically designed for the purpose of locating and analyzing metal and mineral deposits that are out of reach of conventional metal detecting equipment. It sells for $895 programmed for a single element and includes a one year limited warranty. For more information, do not hesitate to write to Dell Systems, P.O.
