Huhh, got coin indications but no coins? One of the first things I've always done with any detector I've recently acquired is just simply throwing down some
coins and familiarizing myself with what the machine tells me. Then do a bit of pin pointing. Now go to the local park and spend a couple of days with it. Its all about learning your machine. Cant say how many new detectorists I've watched get frustrated and retire *or spend a bunch of money buying new magic wands* their machines because they don't have the patience to learn.
Good luck and happy hunting.
