I had the machine on GMP basic 1 (program 1).
01. When sweeping across the ground no numbers appear on the control box in the middle square until you actually hit a target (is this correct) ?
02. The machine sounded silent until a target was hit, is this normal and is this because iron is discriminated out ?
03. If iron is discriminated (10) do you lose any important signals in this program set up ?
04. Lee B mentioned putting GB on tracking.... How do you achieve this ?
Sorry for the basic questions but any help much appreciated.
Thanks to everyone for the great advice and help
