If you get a pulltab reading on your targer ID detector, do you pass, or do you dig? You just might be surprised by digging a pulltab or zinc penny signal indication I've found some relly neat things in that target zone. Location is the Key. I use both kinds of detectors, Target ID for nice victorian yards and non metered for relic hunting with a sharpshooter as a digger, just the right tools for the right job at hand. JMTZ's
