Hey guys the conversion is simple enough but once you put an Coiltek coil on the SDC you won’t be able to fold it down unless you put the stock 8″ back on. Minelab says this https://www.minelab.com/usa/customer-care/product-notices?article=353456
I’ve never tried one of the new Coiltek SDC coils, but certainly have had great experiences with their coils overall. Sometimes I miss my old GP Extreme with the orange 14 round mono. Terrific nugget detecting combination. I’ve read that they do not void the warranty. It would be ideal if Coiltek or Minelab would simply update their websites to state this, but given that a degree of user error may be involved with the process of attaching the coil to the SDC perhaps they are hesitant. My recommendation is to contact Coiltek and Minelab directly. Get it in writing.
