because of the latest trend in australia not to carry cash to buy most anything,using smart phones and credit cards is now the way to go.detecting has forced me to dig everything that squeecks burps or farts in the hope that it is somewhat valuable and keepable.no more not digging pull tabs or screwcaps off wine bottles.so buying the latest detector was really a waste of money.the other six detectors that i have still found stuff.the new one found the dwindling targets well.ah well,shouldn't have listened to all the hype again.emu bob.see ya
