Z-7K X-Coils require an adapter to be made using the plug end of your existing coil to operate.  This process requires soldering skills and it is recommended the adapter be made only by a professional electronics technician as it can damage your detector if made incorrectly or poorly.   

If you're based in Australia we will provide you with the contact details of a person that has made adapters for a large number of our customers.  Outside of Australia you'll have to find a skilled electronics technician to create it for you and we can supply them the instructions required to make it.

Contact us prior to purchase if you have any questions with the adapter process.
