If it s a nugget you won t be able to tune it out unless it s very small Many strong hot rock signals will disappear rapidly when you lower the sensitivity level whereas a strong nugget signal will just get weaker Of course the best way to check a possible hot rock is to flip your mode switch into IRON DISC 2 Highly Mineralized Soil Unfortunately this is where most nuggets are found The Gold Bug 2 will handle all but the very worst soil Solutions Switch to the HIGH mineralization setting Ground adjust very carefully and often Lower the sensitivity Ground adjust to a height just high enough to eliminate most false signals and adjust your stem length to sweep at that height 3 Dissolved Salts On a wet ocean beach or moist inland soil Solutions Same as highly mineralized soil ee 23 FALSE SIGNAL continued 4 Junk Nails pull tabs beer cans etc The Gold Bug 2 was designed for extreme sensitivity to small bits of gold That means it s also extremely sensitive to small bits of ferrous metal Solution Hunt in the NORMAL MODE but use the IRON DISC Mode to check targets to see if they re ferrous Fortunately there s not much junk in nugget country and with practice you ll be able to recognize a lot of it Nails for example will respond with two beeps across the length of the nail end to end but only one beep when the search coil is swept at right angles to the length of the nail Also most trash is sh
