7. AutoTrac
AUTO TRAC™ allows the instrument to automati-
cally readjust the Ground Balance setting during
searching. This readjustment allows for natural
occurring changes in the ground mineral of an area.
By maintaining an accurate Ground Balance,
detection depth and stability are enhanced. AUTO
TRAC™ is recommended for typical search condi-
tions. If, however, a great deal of decomposed
man-made iron is encountered, AUTO TRAC™
OFF, or a reduced AUTO TRAC™ SPEED is
advised. AUTO TRAC™ operation is affected by
TRAC INHIBIT.

8. Trac View
When ON, "TRACK" appears on right side of
display when AUTO TRAC™ makes adjustments
to the Ground Balance setting.
TRAC VIEW offers a way to observe
Autotracking. When ON, "TRACK" will appear
momentarily on the right-hand side of the display
just above the SignaGraph™ while AUTO TRAC
is adjusting. This information is valuable when
attempting to determine an appropriate Trac Speed.
It may also be a valuable aid in determining the
relative ground conditions. Re-occurring
"TRACK" would indicate difficult ground. In
average ground it is desirable to see some tracking
occur (see TRAC SPEED).
