|:"Digging Deeper with the
Part I: Starting Off
Deeper with the DFX begins with a basic overview
of the DFX, the principles of metal detection, and how
the DFX is used. Since all settings on the DFX are
changed through the DFX's menu system, a "comfort
level" with the DFX's menu system is important and a
chapter is dedicated to this required skill.
Following this is an overview of an example detecting
session. Next is a chapter focusing on a few of the
most important settings that will help in virtually all
programs. These chapters provide a good foundation
for using the DFX.
Part II: Learning More
next few chapters look at a number of areas in more
detail. The DFX identifies items that it detects
based on the VDI number system and a more detailed
chapter on VDI numbers is provided. Next is a
chapter on understanding ground mineralization and
includes ways to measure both the VDI response and
strength. Next is a focus on the
"All-Metal" mode of operation. It is the
"All-Metal" mode that is the basis of the DFX
operation and by understanding this foundation, one can
better understand the more advanced capabilities of
"Discrimination Mode" which is provided in the
next chapter. After this, there is a chapter on
Mixed-Mode. Following this is a chapter on optional
search coils provided by White's along with coil
performance graphs. These chapters provide more
details of how the DFX works, what it's up against in
terms of ground minerals, and further information on the
VDI number system that is the basic "language"
of the DFX.
Part III: Putting it All Together
next couple of chapters looks at creating custom DFX
programs and presents a number of example programs.
The final chapter provides a summary of the all the
DFX settings with "adjustment guidelines" for
Appendix A: Important DFX Procedure Cross-Reference
appendix provides a quick cross-reference to the
- How to Ground-Balance the DFX.
- How to Confirm that the
Ground-Balance is Set Correctly.
- How to Pinpoint Targets.
- How to Adjust the DFX for High
- How to Measure the Ground's VDI
- How to Estimate the Ground
- How to Adjust the GROUND
FILTERING and SWEEP SPEED
- How to Adjust the RECOVERY
- How to Reset the DFX.
Appendix B: A More Advanced Look at GROUND
appendix presents the results of lab testing on the GROUND
FILTERING and SWEEP SPEED
settings (in 3D-graph form) that may be of interest to
the more technical reader.
Appendix C: CORRELATE Mode Measurments
appendix contains additional technical details.
3D-graphs showing a comparison between CORRELATE
and BEST DATA operating modes for
different VDI SENSITIVITY settings.
