Geophysical apparatus
Geo, that patent is a hybrid between "VLF geophysical" and Turam apparatus. It is for geophysical mapping and doesn't have anything to do with "LRL's" which (as everyone knows) is a designation for fraudulent apparatus. Not much use for detecting individual coins either- it circumvents the "rule of 64" that's been discussed recently on the Geotech "coils" forum, but pays the price of having done so.
If you are interested in constructing something according to that patent, this is the wrong forum, I highly recommend Geotech where there are a few people who actually understand this kind of stuff.
This is the LRL forum. If you expect technical help from the likes of Montana and Hung and Dell, you already know from them in their own words what kind of company you're keeping. By their own frank admission they don't know squat about electronics or physics, would you trust either one of 'em to change a burned out light bulb? Oddly enough, they regard their admitted ignorance as a defense! of their products! "Skeptics" don't have to make this incredible nonsense up, my slogan "read the advertisement" is a solidly paved road to the truth of the matter. Who posts links to Mineoro's website? It's me, not Hung! We obviously know the same thing about what's to be found there. Mineoro's own website and promoters' forum posts are the best source we've got for evidence of fraud to be made public. It's why people like me have argued in favor of allowing LRL fraudsters to say their piece, even when they're "marketing", something that's usually forbidden on forums. I say let the criminals and delusional incompetents be given the opportunity to confess to what they are, and that's something they do well.
Geo, I don't know your educational background. This is an enterprise where without high school level physics and math as well as practical knowledge in electronics, you're doomed. (That's why they teach this stuff in public schools-- so those who find the subject matter interesting won't be doomed.) One of my very well-educated co-workers just took a grad level University course in this stuff and found it challenging, but thankfully earned an A in the course. Thanks in part to my abundant file material on the subject, something to which the other students had no access.
After all, the physics basics have been kicking around for something like 100 years, it is only the technical ability to achieve improvements in performance of practical products that has changed.
The first patent on a VLF induction balance discriminator for ID'ing coins dates back to the late 1800's, before "electronics" even existed, it was just electricity. The patented device was a bench model for use by banks to detect counterfeit coins, but the physical principles haven't changed, any modern metal detector engineer would immediately recognize it for what it was. ....Sorry, I don't have the patent number, but the thing really existed, a few years ago I printed it out, but sorry, I don't know what file I stuck it in. No majick, just creative use of the technological possibilitities that presented themselves at that time. And, that was an extraordinarily creative period of scientific-technological endeavor, it created the modern world as we now know it.
