The Minelab M9 double-D searchcoil was specially developed for the Manticore. It is waterproof up to 5 meters and ideal for underwater and beach searches. At just 362 grams, it is the lightest searchcoil for the Minelab Manticore. The narrow design offers better selectivity than the standard 11" coil. Thanks to the flat profile, the coil can be easily swung in the water with little resistance.
