This coil is the Miner John Designs 8 x 12 TDI Folded Mono coil. It’s the only elliptical Mono coil that is designed and tested to work well with the White’s TDI line of detectors. We tested it in the California and Nevada gold country, as well as some of the toughest areas in Australia, and it performed extremely well. This coil is now the stock coil on the Special Edition TDI SL sold by White’s Electronics, Inc., USA!
You can submerge this coil up to 3 feet, and it comes with a 3 year warranty and coil cover (skid plate). The coil weight with cover is 1 pound 1 ounce.
This coil is not compatible with Minelab detectors.
