Also included with the VANQUISH Pro-Pack. MULTI-IQ TECH. This small DD coil combines the power of multiple detectors into 1. Equipped with our revolutionary Multi-IQ tech, it automatically employs 5 frequencies at once so you can search all metals, all soils, all the time. WATERPROOF. Don't stop your search at the beach or the river bank. This coil is waterproof and can operate in harsh environments. FIND MORE TREASURE.

Plus, it can fit in very confined spaces. PROTECTIVE SKID PLATE. Includes a back replacement skid plate to keep the coil protected from potential damage. MINELAB offers a wide variety of coils so you can tackle all terrains and all targets.
