being new to detecting, i bought a vaq. i believe i made a good choice, find stuff with it. 3 weeks with it now, can gb with no probs. i set up a test garden to hear the difference in sound with clad coins, pull tabs, brass, iron, etc. at different depths. the modern quarter, dime, nickel can only get at 6 inches deep max. pennies, tabs, iron put off a better hit at 8-10 inches deep than the coins do at 6 inches. esp the dime. i can live with it, just asking is that the norm?
