Garrett Sea Hunter XL 500-Need Large coil

[agd]

I would like to add a 4'X4' one inch PVC coil to this detector-how would I make this coil to hunt for larger deeper treasure?-AGD

Try to use 8 to 11 turns of 1mm pvc wire.

Thanks-I have all types of wire, so @ 160 ft of wire are needed to make this coil. -AGD
