[QUOTE="maulbrooks, post: 599728, member: 20653"] Hi, Horses for courses. These are 2 different machines trying to find fine gold in different ways. The sd2300 is probably closer to the ideal given the overall mineralisation of Australian soils. Detectors send out a magnetic field that cuts across the conductive small nugget inducing a small current in the nugget which creates its own magnetic field which is read by the detector. The Gold monster is a cheaper VLF detector that blasts continuous high frequency that greatly excites currents into the small nugget causing a larger magnetic field, easily read by the receive coil of the detector. If this was the only consideration the gold monster would be superior to the sdc. However blasting high frequency from a transmit coil also excites currents in iron and other minerals in the soil masking the nuggets magnetic field so the detector cant see it. Using gold mode or auto balance etc to try to overcome this problem just makes the gold monster worse than the sdc2300. The SDC2300 is a single frequency single coil pulse detector. It sends one pulse into the ground then listens for a magnetic field. The delay in listening allows the nuggets field to decay quickly. A pulse induced magnetic field is much smaller and shorter lived than those induced by high frequency detectors and this coupled with the fact the the smaller the nugget the smaller the field means the sdc can miss small nuggets especially if the coil is moved on quickly. However the sdc can detect small nuggets deeper in mineralised soils. So which detector depends on where in the world you are. Most of the cost of better detectors in Australia comes from overcoming mineralisation. So these videos of detector air tests on small nuggets are worthless comparisons, the only value of an air test is to demonstrate if your detector is working properly. Cheers [/QUOTE]
