ADVANCED CONCEPTS

Identifying the source of detector noise
EMI: Hold the coil still more than 100 mm (4 inches) above the ground� If noise is present, it is likely to be EMI�
Conductivity: Pump the coil up-and-down approximately 1 metre (3�3 feet) above the ground� If noise is present, it is likely to
be casued by Conductivity�
Ground Noise: Swing the coil over the ground� If noise is present, it is likely to be ground noise�
Mono vs. Double-D coil
Coil winding configuration
Mention the pinpointing difference at all?
When to use the Double-D coil
Use of the Double-D coil is only recommended if good results cannot be achieved using a Monoloop (Mono) coil�
Automatic Ground Balance
GPX 6000 tracks automatically to changing ground conditions during normal use� It is effective for typical detecting in less
variable ground� Automatic tracking adapts more slowly to ground conditions than Quick-Trak�
Ground Type
Ground Type controls the amount of unwanted ground noise that is removed from the
audio response�
Setting the Ground Type
1. Press the Ground Type button to toggle between Normal and Difficult�
2. The icon for the currently enabled Ground Type is displayed�
Ground Type guide
Difficult (Default)
Removes excessive ground signals from audio
` Suitable for difficult (mineralised) or variable ground
` Generally gives smoother audio
CONTENTS
` Ideal for less experienced users
Normal
Removes fewer ground signals from audio
` Suitable for normal ground (less mineralised)
` Generally gives noisier audio
14
` Useful for more experienced users
