Hi Esteban,
I saw this picture from you... posted on page 2 of this thread...
Now... I know that circuit cause was employed in a pinpointer stuff (russian schematic based on that magazine too, I think first time I saw it was around 1989, is that possible ?) but know for use in pinpointers not LRL. I remember there's a lowered amplitude when e.g. iron is near...
Now this that's really surprising to me... see that stuff used for LRLs too I mean! It's very basic circuit , kind of hartley osc...
Which kind of signal variations you read in presence of a gold target ?
And which is the range you noticed from it LRL behaviour in relationship with which target/size ?
Kind regards,
Max
