Identifying Targets before You Dig with tone
The Treasure Commander TC3X provides you with two ways to identify targets before
recovering them. The first is the indication on the LCD screen via the eight Metal
Category segments. In addition to the visual indication, the audio response will vary
based on the type of metal that has been located. The four tones and the metals that
correspond to each are defined below:
•
Bass Tone: Ferrous metals such as nails, smaller bolts, stainless steel, cast iron
and very small pieces of gold
•
Low Tone: Tinfoil, aluminum, nickels, newer pull tabs (rectangular style) and some
gold jewelry
•
Medium Tone: Older pull tabs (winged style), bottle and screw caps, newer U.S.
pennies (post 1982), newer Canadian $1 and $2 coins, small silver jewelry, most
gold jewelry and military artifacts such as bullets and buttons
•
High Tone: Older pennies (pre-1982), dimes, quarters, half dollars, dollars, and
silver jewelry
