I saw that very thing on an episode of Modern Marvels. Love that show.

You can also usually size the target in pinpoint mode by judging how big a footprint the target is giving you. Coins and large objects sound very different when pinpointing them. It is all a matter of getting out there and spending lots of time in the field. No matter what advice or knowledge you may gleem from people sitting behind a computer screen, phone or tablet, until you put it to use in the field you will not understand. Spend the time and it will all come together. Who knows, after a few years you may be answering newbie questions.

Excellent advice. Lifting the coil several inches will let you know if it's a can or large iron and allow you to move on and save digging those good sounding junk signals.
