coplanar coil

[michael88]

Hello,
Has any one made a coplanar coil and used on the minelab gpx4000? Curious of results and how it was wired at the control box.
Thank you, Mike

Hi Mike
I have made several,6, 8, 18 inch,all worked well.
Just follow Dave Emery's post and you will have no problems.
To set the null,I used a meter on the RX,and feed a signal in with detector.
