Thanks Steve, your advice helps me to decide to buy an Equinox 800, because I have already saved all your instructions and now I will read the manual, while the detector arrives. Greetings from Venezuela, oh and I report you, here the detetocrists to deal with the magnetite, they use a magnet and every time the detector gives a signal, they pass the magnet to the ground and if it continues to sound it is gold, and if it does not emit again sound was iron or magnetite.
