Owner’s Guide MXT PRO White’s Electronics, Inc.
Congratulations and thank you for choosing White’s MXT Pro. The MXT series, which by design marry “versatility & high performance” with “simplicity of use”, is a wildly successful metal detector design. I’m proud to put my name on the MXT Pro. As well, I’m proud the MXT is grouped among a handful of landmark metal detector designs. Among the highest tribute, success in the field has earned the MXT “benchmark status” for which all other metal detectors are judged.

There are rubber washers between clevis/lower rod and loop ears. Use only nonmetallic washers, fiber bolt, and thumb nut to secure loop/search coil to clevis/lower rod. 3.
Chapter 1 MXT Pro Batteries Batteries Using the Standard Battery Holder 1. The standard battery holder holds eight “AA” cell batteries equaling 12 volts total. Alkaline batteries are recommended for use with this model. During normal searching conditions you can expect about 40 hours of hunting time from a quality set of eight alkaline batteries. 2. Non-alkaline batteries can be used in this holder.
Chapter 2 MXT Pro Batteries Rechargeable Battery (Opt.) A rechargeable battery system is not standard equipment with your MXT Pro, however, two different high quality systems are available. White’s rechargeable battery #802-5211, and charger #509-0022 are the recommended standard system and offer quick charge and overnight charge options. (QUICK CHARGE IS FOR USA ONLY. It is not available on 220-240 volt.

Prospecting Mode Only, Trigger Squeezed and held, or pushed forward and locked, temporarily disables ground tracking (same function as holding Grab) “MUSICAL NOTES” Selects different types of variable tone or pitch options. GRAB 1.
Chapter 3 MXT Pro Quick Start Instructions With the MXT Pro properly assembled and the batteries installed, follow the instructions below to start finding valuables! 1. Set the Ground Balance Toggle to the Ground position for normal dirt, Salt position for saltwater beaches or alkali desert regions when wet. 2. Set the Trigger Switch (under the handgrip) to the center (Primary Search) position. 3.
Chapter 4 MXT Pro Display MXT Pro Display The MXT Pro display and reference label below the display provide a wealth of information about the metal target. Important; consult the display information only after a solid repeatable audio tone “beep” has been located over multiple search coil passes. The MODE selection changes both the audio sound presentation and the type and content of the information shown on the display, better suiting the MXT Pro to the application, Coin & Jewelry, Relic, or Prospecting.
Chapter 4 MXT Pro Display Half block indicating detector is not certain but possible. 2. Blocks- A series of 16 blocks appear along the bottom portion of the display and line up with the indications on the reference label below the display. It is important to note these blocks are a different separate opinion compared to the VDI number and they may or may not agree. There is significance to how these blocks appear. A full block indicates the MXT Pro is confident of indication.
Chapter 4 MXT Pro Display 5. PP Blocks- Trigger (on the handgrip) squeezed and held or pushed forward to lock, the PP blocks aid in pinpointing the exact center of the metal target. Only when the search coil is directly over the center of the metal target (longest possible length PP Blocks) is the depth reading giving you the most accurate depth indication in inches. Also of importance is that with some experience the relative size and shape of the metal target can be recognized during pinpointing.
Chapter 4 MXT Pro Display 3. Text/Labels - In Relic mode you will see target ID labels in the upper right of the display. The text labels are Hot Rock, IRON, BUTTON, BULLET and BUCKLE. Obviously there are many more relic items possible. Just keep your imagination open for what possible objects were produced in metal and how they might compare in size and alloy to the ones mentioned above. NOTE: Before squeezing the trigger, the quarter Block reading is questionable.
Chapter 4 MXT Pro Display Prospecting MODE The Prospecting MODE changes the audio and display information more dramatically compared to switching from Coin & Jewelry to Relic. Mode toggle switch Down for Prospecting Gold in its natural state can be any size and shape from very tiny pinhead size flakes to large placer gold nuggets as well as veins of various sizes in quartz rocks. The Prospecting MODE takes these facts into consideration and changes the display accordingly.
Chapter 4 MXT Pro Display 3. GND- Indicates the phase (measurement) of the ground. This is useful in two different environments. A. Use Ground Numbers primarily to Find Gold Bearing Ground in a Dry Wash. Within a dry wash the gold will settle with the heavier materials (black sands). When searching you notice the ground phase is declining (lowering in number), generally you are working further away from the heavy black sand deposits.
Chapter 5 MXT Pro Controls Controls MODE COIN & JEWELRY MODE *Trigger (on handgrip); Trigger Center Position “Primary Searching” (traditional DISC control). With the Trigger on the handgrip in the center position, the Discrimination control works like most traditional metal detectors, metal items below the Discrimination control setting are suppressed (quiet or broken) by the audio and metal items accepted by the Discrimination control setting produce a smoother solid audio beep.
Chapter 5 MXT Pro Controls DUAL CONTROL MODE indication (0-1”), compared to heavier gold jewelry, which typically indicates with deeper depth indications. “Music Notes” Tone ID. Coin & Jewelry always starts out with Tone ID ON. Targets higher on the VDI number scale respond with progressively higher pitch tones. At minimum discrimination (fully counter clockwise) seven different audio tones represent the entire target range from iron the lowest pitch, to large silver coins the highest pitch.
Chapter 5 MXT Pro Controls Trigger Pushed forward to Lock “Pinpointing/ Depth Reading”. When operating in the Relic MODE and the Trigger on the handgrip is pushed forward to Lock, the same functions are provided as if the trigger where squeezed and held. The audio is changed to an all-metal (no trash rejection) pinpoint mode and the display provides a screen that indicates the depth and intensity of coin-sized targets to further aid in pinpointing exactly where to dig.
Chapter 5 MXT Pro Controls “Music Notes” Tone ID. Starting out turned on, Iron Grunt provides a distinctive grunt for all targets certain to be iron (80% and higher probability). If turned off by pressing “music notes” Tone ID the same VCO audio tone will be heard for all targets. CONCERNING ALL MODES TRAC ToggleThe TRAC toggle selects the type of ground mineral rejection (ground balance) and automatic tracking to ground mineral changes best suited to the specific area.
Chapter 5 MXT Pro Controls Salt water beaches for example or alkali desert regions. The Ground setting will not track into the nonferrous metal region. The Salt setting will. The MXT Pro ground rejection system is capable, in both the Ground and the Salt settings, of considering some iron a ground mineral. If operating in a known salt area, salt water beaches for example, it is not necessary to balance in the Ground TRAC setting.
Chapter 5 MXT Pro Controls indicates a very large target, sweep loop higher over area to confirm if the target may be of interest. 5. In the Prospecting MODE the use of the SAT (variable self-adjusting threshold) control will help to maintain a reasonably smooth THRESHOLD “hum” particularly at higher GAIN settings and will be covered in a later section. 6. While using a steady slow search coil sweep speed, simultaneously advance GAIN towards “+3”.
Chapter 5 MXT Pro Controls (Dual Control) in Coin & Jewelry or Relic - While operating in the Coin & Jewelry or Relic MODES the Dual control operates as a DISC (discrimination) control. DISC (Discrimination) is used to adjust the level of audio rejection against trash metals. The “Triangle” just below NICKEL is recommended for most general purpose searching. In this position, the detector will provide a reject response to most iron and light foil and respond to most valuables including jewelry.
Chapter 5 MXT Pro Controls might be necessary to use the SAT feature and/or reduce the GAIN control. This noisy behavior will make it difficult to recognize a true target (possible nugget) from pieces of mineral, commonly referred to as “hot rocks”. It is not wise to keep a high level of GAIN if the detector will not operate smoothly. This is a false sense of security. Maintain as smooth a threshold as you can.
Chapter 5 MXT Pro Controls Threshold ControlThe THRESHOLD control sets the loudness of the background “hum” or edge of sound. This background “hum” should normally be maintained during searching. In order to hear the tiniest and deepest targets the THRESHOLD “hum” should be set at the faintest audible level. It can be slightly scratchy, chatter or static like but it must be constant so as to not miss that small or deep targets. At this point, we can’t recommend too highly the advantage of using HEADPHONES.
Chapter 6 MXT Pro Pinpoint Technique Pinpointing NOTE: Turn the detector 90° to the first side-to-side loop movement and repeat for “+”ing the center. Pinpoint TechniqueDue to the wide scan nature of modern search coils it can be difficult to locate small targets under the physical center of the loop. Use an “X” marks the spot technique as shown in the diagram to identify the portion of ground the metal target is in.
Chapter 6 MXT Pro Searching Headphones HeadphonesThe headphone jack on the MXT Pro is located on the control box above the battery compartment. There is a dust cover on the headphone jack that needs to be removed before the stereo plug from the headphone is inserted. Replace this cover when headphones are not being used. Most users prefer high quality stereo headphones so White’s has chosen to wire the headphone jack for stereo.
Chapter 6 MXT Pro Searching 2. Trigger (on handgrip) center “primary Searching” position. for digging coins and jewelry that indicate outside the pull tab range. However, note; when aluminum is rejected the probability of digging jewelry substantially diminishes. The highest (furthest clockwise) discrimination setting than still responds to the USA nickel, or a medium sized 14K gold ring, is the highest trash rejection level that still responds to most jewelry. 3. TRAC to Ground position. 11.
Chapter 6 MXT Pro Searching and/or increase the Dual control (Disc) clockwise and try again. An area littered with man-made iron would dictate the Lock setting. On the other hand an area littered with small aluminum foil would not, such an area would dictate the Reduced Gain and/or higher discrimination settings. The 2nd option is Gain.
Chapter 6 MXT Pro Searching too fast, about 2 seconds per pass from right-to-left and two seconds returning from left-to-right. Overlap your sweep path 50% so that you won’t miss the small and/or deeper metal targets. Targets to deep or small to achieve good tone identification will sound at the threshold level tone. 9. Once a solid repeatable beep is located consult the display information.
Chapter 6 MXT Pro Searching preferred over 2 Tone. you won’t miss the small and/or deeper metal targets. The 5th option is Threshold level. It is best to search with a continuous hum or threshold (edge of sound). In many modes you can hear rejected targets (threshold fades) and be made aware when and where concentrations of trash items lay, indicating traffic areas more likely to produce good targets. It, however, also requires more patience and concentration.
Chapter 6 MXT Pro Searching adjustments. If you are unsure if a response is a real target, and/or wish to sweep over any target repeatedly, if is best to do so either holding in the Trigger on the handgrip, or holding the GROUND GRAB button. Squeezing and holding the trigger on the grip or squeezing and holding the GROUND GRAB button, temporarily disables tracking. The 1st option a user should consider is the selection of an appropriate TRAC toggle setting for the area.
Chapter 7 MXT Pro Information Proper care 1. CleaningA. Both the coil and rod are waterproof and can be cleaned with fresh water and mild soap. The control box is not waterproof and must be kept dry. Never lift a wet coil above the height of the control box as water can run down the inside of the rod damaging the electronics. A damp cotton cloth can be used to wipe off a dirty control box. 2. WeatherA. Do not expose your detector to the conditions of a car trunk during winter and/or summer extremes. B.
