Correct me if I'm wrong please. The DD coils from my 7.8 Khz machines would be fully compatible with the 19 Khz Fisher detectors (Goldbug pro/F19/G2) but not with the 13 Khz detectors (F70/F75) right ? So if I was to purchase an F70, F75 or T2, none of my present DD coils would work on these machines ? Thanks.
