Actually I have a metal detector that will locate a dime sized object 12 inches
in the ground. When I start getting close I switch to my pin pointer. Its a $20
metal detector called the Little Wizard. Its normally used to find nails and
such in lumber and used by wood workers to protect their tools. I bought mine
several years ago at Harbor Freight for about
$15 but evidently they dont carry them anymore, however Woodcrafters and
numerous other places do..

It will pick up nails several inches deep and in my experience will locate small
bits of metal with ease.


I should have thought of this earlier...
