Metal Detector Troubleshooting and Repair

Hello All , What I wanted to mention is , since a bunch of Electronic Technicians and Electronic Engineers are members of Thunting.com now or will be joining soon we will be carefull how we post schematics here on this forum !!! Older Metal Detectors that are not in production anymore can be posted here but should be a re-drawn version of the schematic without a company copy-right on it !! I am working on a loop hole version now  !!! Most PCB circuit Board Photos can be posted without any problems . If there is a  copy-right "C" etched on the PCB board , it means if you make an Identical Clone of this circuit Board in quantities of 300-500 then you are kinda violating laws if you re-sell it in quantities . It is always best to make your own "Improoved" or "Modified" version , then you can be proud of your own work , BETTER THAN THE ORIGINAL !!!!!! SO "most" Crystal Clear "HD" photos/images of Metal Detector PCB circuit boards are welcome here on Thunting.com , we just have to be carefull of what types of schematics are posted , that is why I have not posted 10 giga-bytes of schematics here on Thunting.com yet !!!! We are just at a starting point here !!!!! My TECH-TALK under construction signs did not post right where I wanted them  !!! .........Regards........Eugene52

Hello d.p. swing . Sorry I did not see this sooner !!! On this forum questions can disappear quickly into the archives because of the number of new posts everyday . If it is not fixed yet , then there should be two adjustment screws on the pinpointer . Also , the only schematic I could find is for automax version 2  , but you can check for similarities...You can also post a picture if you like ......Regards......Eugene

Hello all, I recently was given a older "mp3 pro digital" detector from a friend.The wire connecting the coil to the control box must of been removed for whatever reason.Was wondering if anyone cold help me out on the wiring? On the PCB Reads R,B,W,G. But has 5 soldered connections? Im not sure where the extra wire should go.Thank's in advance.
