This message is for Bob Parnass and anyone else wondering about
metal detectors.

I just bought one of those $89 VLF discriminator metal detectors from
Radio Schmuck.  It works quite well although it gets heavy to hold after
a couple of hours of searching.  The thing is capable of detecting a 
dime at 6" underground.  While using the detector I discovered a new
form of pollution on the earth: pulltabs.... the thing picks 'em up
like gangbusters.  What is needed is a pulltab detector to go along
with your metal detector...when you find something you would use the
less sensitive but discriminating pull tab detector to figure out
whether you should dig/scrape.  The only problem is that a pull tab
ring is about the same size as a diamond ring!
 
 Any ideas?  perhaps an imaging metal detector that lets you *look* at
 your find.
