I dont know bout your detector but on mnine i can turn the Discrimination and notch to max and not lose silver quarter, dime and penny signals. Nickels are cancelled out and any fine jewelry are cancelled, also. I would imagine gold coins would be nulled out too, though i dont have any to try it on. Experiment with your machine on all the settings till you know exactly what is cancelled and where the settings were when the items were nulled out. If your using a meter, make a log of the number readouts for different items and carry it with you to reference on the site. Dont rely on you meter as what was said befoe gold jewelry will read very close if not exact as pull tabs. Use your gut instinct on a questionable target and dig it, as digging a pulltab or other junk beats walking away and always wondering if you let some nice gold trinkets get away.
