HELP,THE MANUFACTURE,COIL DD!
HELLO, FRIENDS,. NEED OF A GOOD TECHNICIAN TO TEACH ME, THE MANUFACTURE, one ,coil DD,METAL DETECTOR (P.I).................. 30 inch S,, DIAMETER
1200 uH -16 R.(16R is the value of ONE COIL, or the total of two? 16 OHM?? OR 1,6 OHM??
HOW MANY ROUNDS OF YARN IN EACH COIL? THICKNESS OF THE SAME?
16 R 1R6 OR, IS THE SAME AMOUNT? OR NOT?
Very grateful!

1200uH probably has 16 ohms. You can use the coil calculator (top post of this forum) to figure out # of turns. Since you don't say what you are building it for, it will be difficult to help any further.

is the inductivity 1200 uH for only RX coil? write pls what PI detector you mean looking for the coil data.

I'm sorry, ignorance! the drawing, which I sent above, is for VLF, s
I want DD COIL, FOR, my DEEPERS-7.PULSE INDUCTION.NOW THIS NEW DESIGN IS CORRECT? OR NOT? DESIGN=8
CALCULATE NOT KNOW, ABOUT THE POST ABOVE.
PLEASE CALCULATE FOR ME YOU CAN BE? 30 inch S,, DIAMETER
1200 uH -16 ohm.(HOW MANY ROUNDS OF YARN IN EACH COIL? THICKNESS OF THE SAME?
thank you very much

No, that's not how to build a DD coil. There is information in other threads on this forum that explain building DD coils. I seriously doubt a Deepers PI uses a 1200 uH coil, you should re-measure this.
