I think most of non working LRL´s(and expensive) are MADE IN GREECE.
And if one of this can work as LRL,i´m sure they are more popular...
So many LRL´s produced in Greece

may be any of those detect wall electric lines very good

1st: LRL is an very important "task" finding real valuable treasures!

that's why 2nd:
It would also be very important to create a testfield with the needed "energy-fields" for testing that kind of stuff.


If possible bury some non-golden stuff that developes the same LRL-aura and put it behind some massive glass-wall, so everyone can see where it is buried but still the half of the energy field remains within the ground.

Another easier way would be finding or burying some "long time ago" object, digging a little hole so it's surface becames visible but leaving it there and then secure this hole from falling in and put some stable glass cylinder or plate over the opening.

In both cases there still should remains at minimum 50% of the formerly LTA-energy-field intact so tests with LRLs are possible!


btw. what are the similarities between Alonsos PD and the NASA ferrit locator? Those are in principle completly the same, aren't they? Shure it makes a little difference using omega coils or whatever with the PD but the positive-negative balance coil circuit that needs a very stable and accurate adjustment is the same.

That's why we just would need a much larger ferrite (30cm lenght!), more power (30 Volts), a quarz controlled oscillator and more coil windings for getting the real good results.

Perhaps mikebg has already the analysis ready for this:

I will post soon an analysis of maximal amplifier gain for ideal BALANCED REGEN metal detector.

you mean something like that ???

The principles of operation are in no way the same. They are not even similar.
The detector you show in the schematic is basically a 20 khz pinpointer metal detector that depends on eddy currents to detect metal objects at a range up to 10 inches. It uses a pair of critically balanced ferrite coils to gain more range than a typical ferrite pinpointer that may be able to detect up to 5 inches using the principle of eddy current detection by detecting magnetic field variances at the ferrite loop.

The Alonso pistol is a passive receiver with a fixed tuning capacitor and an RF detector stage and filter stage to pass VLF at about 60 Khz. It is said to work with or without a transmitter nearby, and is thought to work by sensing differences in the RF signal sensed at the ferrite loop. The only similarity between the two circuits is they both use coils wound on a ferrite. In fact, the Alonso pistol ferrite circuit is more similar to an AM broadcast receiver than to a metal detector in design. The AM broadcast receiver also uses a coil wound on a ferrite, and it uses the same tuning method, except with a variable capacitor that is tuned to a higher frequency.
