location. Listen for the loudest, most pronounced audio signal. The Target ID Cursor will 
indicate the target's probable identity on the Display. The Target Guide above the cursor is an 
aid in determining the identity of the target. 
 
PINPOINTING: 
 
Precise pinpointing is an important feature of your detector. Press and hold the PINPOINT 
Touchpad and the searchcoil can remain steady and hover over the target. Slight movements 
of the searchcoil will be reflected on the Upper Scale of the GTA Display. The greatest 
deflection or illumination of segments-right to left- on the Upper Scale indicates the target is 
directly beneath the center of the searchcoil. At the same time on the Lower Scale the 
illuminated segments, left to right, indicate the depth of coin-sized items.  
 
Another method of Pinpointing and Depth Reading used by many treasure hunters is as 
follows. After acquiring a target, set the coil on the ground near but not directly over the target,  
then press and hold the Pinpoint Touchpad. Do not lift the coil from the surface but slide it 
around watching the LCD Display. When the two rows of segments touch each other, the 
target is beneath the center of the coil at the depth indicated by the lower scale. 
 
JUNK TARGETS: 
 
The detector in its initial factory default settings, will not respond audibly to most junk items. On 
occasion, the detector will respond  with a signal that is not clear and sharp as that of a coin. 
Before digging some of these "blips"  see where the target registers on the Graphic Display. 
For many trash targets the detector will show two cursors at once or will give varying target 
identities as multiple scans are made over the item. 
 
It is not unusual for a large object such as an aluminum soft drink can to give an audio signal 
indicating that a good target has been discovered. This is nothing to be worried about. The 
target has been located due primarily to its size, conductivity, and nearness to the searchcoil. 
 
When you determine that it is time to turn the detector off, it takes only a simple press of the 
POWER Touchpad. 
 
OPERATING ADJUSTMENTS: 
 
 When you press the POWER Touchpad the first time, your detector is ready to operate with 
the factory settings in place and the discrimination set to find coins while eliminating most trash 
from detection (Mode B). Many hunters never change from this "Notch" pattern. If you wish to 
change operating modes however, press the Last Mode Touchpad and the detector changes 
to Mode A that is established originally, to find all metals. 
 
The discrimination pattern is easily adjusted to meet the operating needs of any detector 
operator. From locating only one specific item, to locating all metals, it is simply a matter of 
pressing a couple of touchpads. Press the directional arrow to move the cursor either left or 
right. When it comes to the position you wish to turn on or off, press the "Set Disc" touchpad. 
The segment then is either illuminated or not . It is so easy to customize the discrimination 
pattern to fit your own desires.
