On Monday I bought a Radio Shake Discovery 1000 metal detector on Craigslist and the seller didn't have the search coil. Although I bought this metal detector for my dad, I am looking forward to finding treasure myself around the Fort Fisher area at Kure Beach NC. Is there any type of search coil that would work with this metal detector that is not expensive. If so, please provide me the web address. Thank you and I greatly appreciate your help.
