Minelab Gold Monster 1000 Universal Metal Detector with 2 Search Coils, Waterproof

  • KIT INCLUDES: Minelab Gold Monster 1000 Metal Detector | 10x6" DD Waterproof Search Coil | 5" DD Waterproof Search Coil | Headphones | Lithium-Ion Battery | 8 x AA Batteries | Lens Cleaning Cloth | Minelab 2 Year Control Box & Coil Warranty.
  • 45 KHZ VLF & 24-BIT SIGNAL PROCESSOR: This primary combination greatly boosts sensitivity to gold beyond that of other single frequency VLF detectors over a wide range of nugget sizes, without introducing excess noise and false signals..
  • IMPROVED DISCRIMINATION: The GOLD MONSTER 1000 also has improved ferrous/non-ferrous discrimination and copes better with conductive (salty) soils than higher frequency detectors, making it the perfect choice to maximise your gold recovery..
  • VERY LOW FREQUENCY: VLF (Very Low Frequency) is a conventional single frequency sine wave continuous transmission technology. This is the traditional type of technology used in most basic metal detectors. Single frequency sine wave detectors create an electro-magnetic field, which is transmitted into the ground in a continuous wave. The receive signal processing has improved enormously. ​.
