The MXT Edge

Getting More from the White's MXT Technology

Part I: Basics of Using the MXT
          The MXT Edge is divided into two parts.  In Part I, the basics of using the MXT are covered.  Part II covers a number of advanced MXT topics such as VDI numbers, ground mineralization, optional search coil performance, and additional feature details that are sure to be of vital interest to the serious hobbyist.
          Chapter One provides an overview of the book and the approach used in the organization of information presented within it.  For example, the book is organized to both, be read cover-to-cover and to serve as a reference.  To assist with the latter, individual sections repeat important principles to allow those sections to better stand on their own when used for reference.
          Chapters Two and Three provide an overview of the MXT, its features, characteristics, and operation fundamentals.
          Chapter Four covers the MXT controls.  One of the controls is the "Mode Switch" which changes the basic mode of operation or "program" that the MXT runs.  Chapter Five is dedicated to examining the COIN & JEWELRY, RELIC, and PROSPECTING operating modes.
          The next three chapters focus on hunting examples using these three distinct operating modes.
          Ending Part I, Chapter Nine provides a number of additional tips and techniques to enhance further the MXT operator's abilities.

Part II: Advanced MXT Topics
          In Part II, a number of additional topics are presented to compliment Part I and provide a more thorough understanding of the technology of the MXT.
          Basic to the operation of the MXT is the VDI number system.  This "Visual Discrimination Indication" system is at the heart of how the MXT reports target information to the user.  Chapter Ten takes a detailed look at the VDI number system, the target and ground factors that cause VDI numbers, and the interaction between the VDI number system and other features on the MXT.
          The MXT is constantly working to overcome the effects of ground mineralization in the search for valuable targets.  Chapter Eleven examines the details of ground mineralization, what PROSPECTING mode's GND numbers mean, how to use them, how to estimate the strength of iron-based mineralization, and much more.
          Chapter Twelve provides an in-depth feature summary organized based on the MXT's internal design – not based on the unit's knobs and switches.  Need more information about a feature?  This chapter provides a different perspective on the MXT's bells and whistles and includes more in-depth discussion of some of the more esoteric features.
          Everything the MXT finds must first be sensed by the search coil on it.  Chapter Thirteen takes a detailed look at the five White's search coils currently available for the MXT.  3-D sensitivity patterns for each search coil are shown for both coin-sized and nugget-sized targets.  Graphs showing the results of performance testing of the five search coils in different strengths of ferrous ground mineralization are also included.

Appendix A. Important MXT Procedure Cross-Reference
          This appendix provides a cross reference to these important MXT procedures:

  • How to ground-balance the MXT.
  • How confirm the ground-balance is set properly.
  • How to pinpoint targets with a concentric (round) search coil.
  • How to pinpoint targets with DD (oval) search coil.
  • How to verify peak stable discrimination mode GAIN setting.
  • How to estimate the strength of ferrous ground-mineralization.
  • When to set the TRAC switch to LOCK, SALT, or GROUND.

Appendix B. Bench Test Illustrating MXT Features
          This appendix provides bench tests to illustrate the MXT's Self Adjusting Threshold and Mixed-Mode audio features.

Appendix C. Pinpointing Coil Dead-Zones
          This appendix provides 3-D graphs showing "dead-zones" that occur very close to the search coil that beginners, learning pinpointing skills, should know about.
