Marc Lowell - Metal Detector
Marc, as seen from the pedestrian foot bridge, paces back and forth, sweeping for treasures big and small.
A path is swept for hidden finds under the earth. This place is frequented by many people sitting on the grass who occaisionally lose coins, watches, rings, or keys.
On this dig Marc finds a vintage soda/beer can pull tab. The metal detector does not discriminate between this piece of tin and a gold ring as they are both circular in shape. Each find has to be dug up to distinguish between treasure and trash.
Once there is a strong enough signal, out comes the knife or trowel to search for the treasure.
After the metal is detected and dug up, Marc carefully replaces the divot in the earth. It's a best practice of all good metal detectors.
