Metal Categories: The eight (8) segments that appear in a semi-circle on the LCD
True Touch screen provide you with an indication of what a detected target might
be. Categories of commonly found targets - treasure and trash - are provided on
the screen. The following figure shows what types of targets will register in each of
the eight segments. A useful function on the TC3X is the ability to accept or reject
any of the segments independently from each other allowing you to quickly and
easily create a custom program designed to handle any conditions you might come
across in the field. Use the Notch Mode to setup a custom Notch or Discrimination
Pattern. ( see Page 10)
It is important to note that the eight segments capture commonly found targets but
not all targets you might come across are listed. Military artifacts including lead
bullets, brass buttons and iron artillery shells or cannon balls can register in
segments that might indicate they are trash. The same holds true for jewelry which
can vary greatly in terms of content and size. The following figure shows the wide
range of segments that can indicate a gold target has been detected. The rejection
of specific segments should be based on a combination of the likelihood of finding
what might be rejected in the specific search area, how much trash is actually
present and how much time you have available to search.

Sensitivity: This function determines how strong a signal is needed to produce and
audio / visual response from a target. Detecting deeper or smaller targets typically
require higher levels of Sensitivity to be used; however, erratic operation can occur
if the level is too high for conditions at the specific site being searched. The
selected level is indicated in the lower section of the LCD display to the right of the
