some areas. Another option for difficult ground areas is searching in
the All Metal mode. Automatic Ground Tracking provides optimum
performance when the changes in the ground mineralization are
progressive. Trac Locking tends to improve performance when search-
ing highly spotty mineral changes or anytime an average ground setting
doesn't provide good results. When Trac Locked, 6T continues to
calculate an ideal "average ground" rejection level. Upon Unlocking
Trac, 6T instantly chooses that level.
8. Beach - salt water beaches present a particular challenge for all
metal detectors. Salt, when wet is conductive like a metal target is
conductive. When searching wet salt water beaches, press Beach.
Beach appears on the right side of the display when ON. Beach ON
changes the perimeters of the ground balance and tracking system to
better suit wet salt conditions. Beach is not recommended for non-
conductive ground types. Ocean beaches, desert salt flats or heavily
fertilized farm fields "when wet" are the only common conductive
ground types.
