Doc’s Goldscreamer Searchcoil Tape is the newest tape on the market.
The picture sort of makes it look metallic, IT IS NOT. It’s just a matte neutral color. There is nothing in the tape that will interfere with your detector.
Just so you have some idea, a 14 inch round coil takes about 4 feet of tape to secure the coil cover.
The Gold Screamer® brand coil cover tape has enough tape to do over 42 – 14 inch coils!! You will probably need 1 roll for the rest of your life.
