LRL Frequence of Gold

[goldfinder]

Gold Bug freq

The original 1980's Gold Bug was all-analog, the new GB's have a microprocessor. Both run at 19.2 kHz for somewhat similar (undisclosed) reasons.

Since it's a thoroughly proven frequency for gold, it ought to work for LRL'ing at least as well as any other frequency a person might fancy-- provided that it doesn't interfere with your metal detector.

It is well known dave that the higher frequency helps to find small pieces of gold. Most of the detectors used for gold prospecting run at higher frequencies. The Tesoro Lobo and the Tesoro Tejon run at about 18 KHz.

frequency for "micron gold"?

LRL fans often talk about having located "micron gold". Maybe their secret gold frequency is in the micron wavelength range. Since the gold thus located is of the imaginary kind, the transmitter evidently transmits only on the j axis. Fortunately without any power on the real axis, the transmitter itself can be imaginary. People make it sound so hard to build an LRL when in fact it's so easy!

The Gold Bug 2 runs at a frequency of 540 gigaradians/fortnight. No wonder it finds such small stuff! And since the phase sweeps through all 2 pi radians, the power is real and the gold thus found is real, users post photos of it. And owners of other models from other manufacturers (not even of LRL's!) don't question whether the GB2 actually works or not. 540 gigaradians/fortnight, the phase rotating through all 2 pi radians, imagine that!

Sorry Dave G. , but I think frequency is measured in Hertz (HZ), not in gigaradians/fortnight

Dave J (not Dave G, by the way) is being deliberately facetious.
However, for the record, his statement of 540 gigaradians/fortnight is still [strictly speaking] correct.

TX frequency of Gold Bug 2 = 71kHz.
Therefore:
71000 * 2pi * 3600 * 24 * 7 * 2 = 539.61E9
i.e. 540 gigaradians/fortnight.

Please be aware that these types of units will become obsolete in the future when we move to metric time. Under the new system there will be 100 seconds to the minute, 100 minutes to the hour, and 20-hour days. Seconds will be referred to as millidays, minutes as centidays, and hours as decidays. Terms such as "a month of Sundays" and "fortnight" will be abolished.

I have no knowledge for this anymore, and I have no interest, so I'm over with my posts.
