White's 15 Inch Magnum Force Field Coil. This coil was designed for Series 1, Series 2, Pro and Eagle detectors. Comes with complete lower fiber rod.
Condition of the coil is excellent, showing very little use, (see photos). Coils this large are designed for hunting large deep relics or caches with the detector being operated in the all metal mode. Large coils are generally designed for can size targets and up. From what I have read the 15 inch coils can go better than 3 feet. Designed for detecting large deep targets this coil is not suitable for hunting singe coins. The White's stock 950 coil is as large as a person should go for single coins and preferably in light trash areas.
