Long Range Locators (LRL)
Long Ranged Locators, also known as LRL is a type of instrument transmitting a sine or square signal in the frequency range from 3 Hertz's to 10,000 Kilohertz's also known as KHz's. The frequencies of different elements or noble metals were in the frequency range mentioned above. Gold had a frequency of around 5 KHz's; however, some Treasure Hunters used the empirical engineering method of obtaining their own frequencies by experimenting with different type of noble metals.
The frequencies used on the Function Generators were dictated by the Federal Communication Commission (FCC,) in the U. S. Any frequency above 10 KHz's is in the FCC domain of frequencies; therefore, off limits for use.
A Function Generator used in the manufacture of the LRL had very low power signal to begin with, and the earth-ground has many-many different frequencies, plus the earth electromagnetic field. The earth electromagnetic field is easily distorted by different anomalies of either chemical, metal or mineral in nature, to cause "Magnetic Grid Points," which would attract the signal from a low power function generator.
The LRL device used two ground probes or rods made from brass welding rods for an antenna. Some LRL were advertised as OMNI type of devices. In order for the device to be OMNI in nature it need only one ground probe; therefore, when using two ground probes for an antenna, one ground probe had a outbound signal, and the other ground probe was the return ground wave signal probe. From experimenting it was found there was around a 30 degree null area off each ground probe. Therefore, there was a 150 degree outbound signal forward, and a 150 degree signal transmitted in the reward direction, for a total of 300 useful degrees of coverage.
A 20-watt audio amplifier was, custom built, and marketed for the so-called Omnitron Noah device. The amplifier could be configured to operate in a 300-degree mode or by separating the antenna ground probes by twenty feet; the device could be made directional, transmitting a signal in a directional beam pattern. The rear antenna probe was the return signal antenna and dictated the direction of the signal travel.
There were rumors that gold and silver Treasure Caches had been found using an Omnitron Noah device; however, no caches were ever documented, by reliable sources.
The Omnitron Noah device operated on the premises that ever material known to man (metal, mineral or chemical) has it's own frequency signature. The device programmed with a frequency of Gold would resonate and reflect a return signal to the Omnitron Noah device. If the Gold were buried inside of an Iron container the Gold signal would pass through the outer Iron container, and be reflected to the ground return antenna probe. In other words the device was a cross between radar and sonar, using the ground as a matrix.
The Function Generator used in the manufacture of the LRL had a problem of not being stable in generating a signal. The Simpson 420A required a precise 4.8 volts to generate a stable signal of a specific frequency. By experimenting the author found by adding a solid-state voltage regulator, built around the 317-voltage regulator chip, a stable voltage could be obtained to where the Simpson 420A Function Generator would produce a stable frequency.
The Omnitron Noah marketed used a Global Max 50 frequency counter to adjust the frequency of the device. The Max 50 Frequency counter only had a resolution of 50 hertz's. Therefore, it was difficult for an operator-user to know about the frequency drift of the Omnitron Noah, or the Simpson 420A Function Generator. However, when a Global Max 110 Frequency Counter was used the drift in the Function Generator could be detected. Even the Global Max 110 had a problem with frequency stability and a solid-state voltage regulator had to be used to read a precise frequency.
To give you an idea of how far the LRL was taken trying to make it find gold caches, countless hours were spent in research and development in field-testing. The Simpson 420A Function Generator used a 5 K ohm variable rheostat to adjust the frequency. It was found from empirical experimenting that the, one turn, 5 K rheostat was not sensitive enough to be adjusted to a precise setting of a 1 hertz's resolution. A fifteen turn military surplus rheostat 3" X 2.5" was mounted externally and driven by a 60:1 worm gear transmission drive. With this type of configuration a frequency change of one hertz could be made while operating the device.
