Delta Pulse 2 Metal Detector

Any person want a best metal detector he should try to make this detector , but if you want to buy this detector you have to spend to much amount for it , but having a good skill in circuit assembling you can enjoy this versatile detector , i have made this circuit about 5 years ago , and enjoy a lot , in below circuit i have connected LEDs bar, every body worry about coil winding , which is very simple  ,    Below are the two pictures of professional delta pulse 2 metal detector ( Pulse Induction ), where i added LM3914 Ten LEDs BAR graph ,  Perfect and versatile detector. Coil winding for this detector is the critical part , if high gauge wire having  less turns , it will directly damage the FET, if more turns then detector may not work , but i prefer the 26 SWG silver wire to be the best choice for the normal coil diameter coils  with the upto 30 turns , if still have doubt about the number turns of the coil just wind the coil up to 40 turns , just take upto 3 taps after 5 winding, with the best tap selection you can get better result, check result .
