Hello Everyone . I have learned that almost all Metal Detector Schematics posted on the internet and Metal Detector/ Electronic Forums are "NOT CORRECT" , even if someone says so !!  Shocked
The schematics posted on This Forum that have a W.L. [Lahr] . or "Ivconic" signature are the Best schematics to Trust !!!! All the other schematics I recommend to use a Breadboard or a wire-wrapping method for building and testing your prototype . We still have a pretty good Library of schematics on this Forum to choose from !!
HH........Best Regads..........Eugene

I've only just started going over the schematics on this one and there are a few things I'd do differently but no glaring errors. So far.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

Hello Luc . I will be checking the Tesoro Lobo schematic and PCB very soon . If I remember correctly the biggest problem was with making the [original lobo 20khz] search-coil . I think the tx and rx inductance values of the prototype coil were never correct .
