Pin out for DD coil

[Mark-VA]

Will a DD coil made for a Minelab PI machine work in the TDI?

If so what is the pin out of the connector?

Thanks,

Yes. Most Minelab coils are compatible. To include the Connector. Just Plug and Play.

Actually would also like to know the pin out ohms. I've got a couple older DD coils I'd like to try by changing the pin connectors.

Here are the pin outs for sd and gp coils, which are compatible with the TDI. The TX will measure under 1 ohm, maybe .5-.6 ohms. On my 11in DD the RX resistance is 17 to 18 ohms. The mono coils have a jumper in the connector to short the tx coil out and rx out pin
