CHAPTER
White’s VX3 represents the latest technology in metal
detecting. The heart of VX3 is a high-performance ARM-9
RISC microprocessor which simultaneously analyzes signals
from 3 transmitted frequencies. Those frequencies — 2.5kHz,
7.5kHz, and 22.5kHz — were chosen for their diverse
responses to a variety of metal targets, resulting in a superior
system of target analysis and identification.
The face of VX3 is a stunning 320x240 color display with an
easy-to-use menu-driven interface. Along with three frequencies, there are three search modes and a three-level Spectra-
Graph® display which provides detailed target information for
each frequency. With a level of simplicity for the novice user
and advanced features to satisfy the experienced user, VX3 is a
metal detector for everyone.
This manual is organized to provide progressive information, a format that attempts to minimize information overload.
If you are a new detectorist, the QuickStart chapter will allow
you to get a quick jump on using VX3. Then, as you run across
new features and want to find out more, continue reading the
manual to get progressively detailed information.
If you are already familiar with high-end detectors (especially those with a menu interface), you might want to read over

pace. There is no need to master all the features to get excellent
performance.
If you need help, White's Electronics is a phone call or
mouse click away. Your dealer is an excellent resource, and the
White’s web site has a VX3 help forum for questions & answers,
tips, and sharing programs. Go to www.whiteselectronics.com
and click on the Forum link. There are also many other on-line
forums for metal detecting where you can chat with other
White’s users and ask questions. Finally, look for a detecting
club in your area. Members are often eager to help people get
started, and there is nothing like having that help close by in the
field.
Conventions
In discussing the features of VX3, we will use Arial-Bold-
Caps
to distinguish keypad buttons and menu selections. For
example, “press ENTER” means to press the “Enter” key on the
keypad, and “select Enable” might mean to select the “Enable”
menu option, probably by using the arrow keys to highlight it
and then pressing ENTER. VX3 keys and menus work just like a
modern computer graphical interface, so things are fairly intuitive.
In some cases, you need to use multiple key combinations,
or combinations with the trigger switch. “Press MENU, ENTER”
means to press and release the
MENU button, then press and
release the ENTER button. But “press MENU+ENTER” means to
press and hold the
press the
ENTER button. Order often matters, so MENU+ENTER
MENU button, and while holding it down
is not the same as ENTER+MENU. If you find that you have accidentally pressed the wrong key or key combo, pulling the trigger switch will usually back you out.
Tip: Keypad buttons usually take you into menus, trig-
ger gets you out.

Two keypad buttons have dual names. MENU/TAB is used
both as an entry button into the menu system, and to “tab” from
one screen area to the next. This tab method is identical to how
a PC interface uses it. So in some cases we will tell you to press
MENU, in other cases press TAB. It’s the same button. ZOOM/
works the same way. VX3 also has four arrow keys, and
VIEW
these may be either called UP DOWN LEFT RIGHT (or UP DN LT
RT
) or represented with the symbols . Any of these
representations might be used.
Most menus are nested, so instead of telling you to press
MENU, then select the Audio menu, then select Search Audio,
then select Discrimination, then select Modulation, we may
instead say, select MENUAudioSearch AudioDiscrimina-
tion
Modulation. This means to drill down through the stated
menu path.
Finally, there is a trigger switch under the pod. It has a normal (center) position, a forward position, and a momentary
pulled position. When we say “pull the trigger,” we mean to
pull it to the momentary position and release it. If we say “Pull/
hold the trigger,” then pull it back and hold it there. This might
be in conjunction with a key press, such as, “Pull/hold the trigger and press ENTER,” which is the same as “Trigger+ENTER.”

4. Wind the search loop cable around the rod assembly, first
revolution starting over the top of the rod. Work your way to
the top of the S-rod. Use the Velcro retainers, one near the
loop and one near the top, to hold the cable in place.
5. Insert the rod/loop assembly into the control box rod
(unlock the cam lock if necessary); the spring clip buttons
will click into the holes. Turn the cam lock to secure. Normally, the S-rod should curve upward.
6. Two adhesive black foam pads are included; they can be
placed on the insides of the arm cup.
7. Adjust the Velcro arm strap so that you can easily slip your
arm in and out. The strap provides extra leverage and control, though some prefer not to use it.
8. Install the battery pack (see next section for details).
9. Hold the detector normally and check for comfortable angle
and balance. Adjust the lower rod extension and/or the arm
cup position if necessary.

The Basics of VLF Operation
VX3 is a multi-frequency (MF) induction-balance (IB) very
low frequency (VLF) transmit-receive (TR) metal detector. In
order to understand what all the user adjustments do, it is
important to have at least a rudimentary understanding of how a
modern metal detector works.
Metal detectors work on the principle of induction, discovered by Michael Faraday in 1831. The typical induction-balance
1
metal detector
and this magnetic field in turn produces a small reaction in
nearby metal targets. A receive coil is used to detect this small
1. The first practical metal detector was an induction-balance
design, built by Alexander Graham Bell in an effort to locate an
assassin’s bullet lodged in US President James Garfield. He
failed — not enough sensitivity. Ever since then, “more sensitivity” has been the goal of every detector.
uses a transmit coil to produce a magnetic field,
Page 1-7

RX
reaction. A so-called “induction-balanced” coil arrangement
prevents the receive coil from being overwhelmed by the transmit signal, allowing it to see very small target signals.
Phase & VDI
Practically all VLF-IB detectors operate as phase discriminators. The received signal is converted to phase, and the phase
is a strong indication of what the target might be. The particular
phase of a target can vary with the frequency of the transmitted
signal, so different detectors designed to use different frequencies can report completely different phase results.
To keep users from having to learn all these different phase
response scales, White’s has chosen to normalize them all to a
standard “VDI” scale. VDI stands for Visual Discrimination
Indicator and is simply a consistent numerical value assigned to
targets regardless of the frequency being used. Therefore, a US
nickel detected with a 6kHz detector will have the same VDI as
with a 15kHz detector. For historical reasons, the standard VDI
scale is based on a 6.592kHz detector and is shown below.
The ability to separate targets by VDI is what allows a
detector to discriminate. Targets with a negative VDI are usually ferrous (iron), and targets with a positive VDI are usually
non-ferrous. Small gold tends to have low VDI’s while thick silver coins have high VDI’s. Other targets like cupro-nickel
coins, brass and bronze relics, and aluminum trash can have
wildly varying VDI’s depending on their alloy, size, and thick-

ness. This means you need to apply your own discriminator —
your brain — in deciding what the VDI responses are telling
you.
Ground Response
Unfortunately, buried metal is not the only thing the detec-
tor sees. Most soil contains ferric oxide minerals, and this min-
eralization looks like a target2. In terms of VDI, practically all
ground mineralization falls in the extreme negative range of the
scale, even beyond most iron targets. But it can vary somewhat
as shown by the gray range in the prior diagram. At most loca-
tions the variation is small, so you can ground balance at a par-
ticular spot and be very close for the entire area. Some locations
have significant variations and you should occasionally re-
ground balance as you hunt, or use automatic ground tracking.
Many locations have enough mineralization to create quite a
strong ground signal, often much stronger than that of a moderately deep target. The VDI diagram on the preceding page uses
vectors to represent specific target responses, with the angle of
the vector representing the VDI value. We can also use the
length of the vector to represent the strength of the target
2. In this manual, we’ll refer to the signal resulting from ground
mineralization (including salts) as the “ground signal” or the
“ground response.”

response, so that a strong ground and weak quarter response
would look like:
The detector will see both signals at the same time, and the
combination of the two can be represented with a third vector as
follows:
The resulting signal appears to be a fairly strong ferrous target instead of a quarter. This is the downfall of the old TR-discriminator designs. Fortunately, since the VDI response for
ground is usually far away from the response of desirable targets, there are ways to deal with it. In a modern VLF motion
discriminator, the receiver determines what part of the signal is
the ground response and, using special filter techniques, normalizes the whole VDI scale to the current ground signal,
resulting in the ground signal being ignored. Graphically, this
looks like:

Any error in the ground balance point can result in an error in
the target VDI response so it’s important to maintain a decent
ground balance point.
Ground Tracking
In order to better handle variations in ground mineraliza-
tion, many detectors now incorporate automatic ground track-
ing (White’s uses the term AutoTrac®). The detector attempts to
determine what part of the signal is due to ground and continu-
ously track the phase and strength of that signal, and eliminate
it. One trick is to limit the range of VDI’s for normal ground
(the grayed area in the VDI scale) and consider anything else a
target. This works for most soils, with two caveats.
Besides “normal” ground mineralization, some areas contain rocks or small pockets consisting of material with slightly
different mineralization than the surrounding ground. The difference in VDI between these anomalies and the surrounding
ground isn’t enough to consider them a true target, but they are
small enough to act like a target to the detector’s ground filters.
These so-called “hot rocks” can create annoying responses in
many detectors.
Another situation concerns soils with significantly conductive salts. A pure salt response lies all the way in the non-ferrous region of the VDI scale, roughly in the midst of foil. Some
salt-water beaches are close to having a pure salt VDI, while
other beaches include black sand mineralization that creates a
Page 1-11
Spectra VX

User’s Guide
composite VDI that can land anywhere between pure ferrite
(VDI = -95) and pure salt. Other areas, like fertilized fields with
residual salt ions, can also have a composite ground response.
Many deserts have a layer of surface salts that have been
leached from the soil; this is generally not a problem as long as
it is dry.
Frequency
Metal detectors are produced using a wide range of trans-
mitted frequencies, from 1kHz up to around 100kHz, though
the vast majority fall in the VLF range of 3kHz - 30kHz. Low
frequencies usually favor thicker targets and metals of higher
conductivity, while high frequencies favor thin and low-conductive targets.
Interesting Experiment: Thickness matters because of a
phenomenon known as skin effect. To demonstrate this,
cut several identical flat squares (say, 1”x1”) of aluminum
foil. Test the VDI response of a single square, and see how
the VDI varies as you stack more squares (tightly)
together.
Low frequencies also do a better job penetrating ground
mineralization, including salt. High frequencies tend to generate stronger ground and salt signals which can limit the ability
to distinguish weak targets. Obviously, when trying to detect
thin low-conductive targets (like nuggets and jewelry) in harsh
ground (like wet salt sand or black sand) there are competing
frequency requirements, so a compromise is necessary. With the
ability to run 3 simultaneous frequencies or any one of them
3
individually, VX
has the ability to deal with a wide variety of
conditions.

•
tings for this program are weak, intended for in-store demos.
These programs are designed for good performance under most
conditions and provide an excellent starting point. However,
ground conditions vary considerably, so some adjustments may
be necessary. Changes to factory programs are automatically

saved to memory and recalled each time VX3 is powered on.
Restoring factory settings is covered in Chapter 7.
Ground Balance
3
’s automatic ground balance system has a fast-track
VX
mode that attempts to balance the system to soil conditions
within 20 seconds of turn-on. If you do not begin searching
within 20 seconds or the ground is unusually trashy, VX3 may
not fast-track correctly and you may want to do a manual
ground balance:
• Squeeze/hold the Trigger, then press/hold
ENTER.
• Pump the search coil over the ground (1-12 inches) until the
background hum becomes steady (usually 4 to 6 times). Make
sure you do this over an area free of targets.
• Release ENTER, then release the Trigger, and begin searching.
Tip: If you release the trigger before releasing ENTER, VX
will lock the screen to pinpoint mode. Simply pull the trigger twice to resume searching.
3
This manual ground balance sequence can be done at any
time during normal search. Once the initial ground balance is
3
completed, VX
will automatically track to most typical ground
mineral changes.

Tip: If VX
3
seems to have an erratic audio only when
sweeping the search coil on the ground, check the
ground balance.
Electromagnetic Interference (EMI)
EMI can be a problem with any wide-band metal detector,
whether a multi-frequency VLF or a pulse induction design.
3
includes a frequency offset to help deal with this. Select the
VX
Transmit Frequency item on the Live Control Bar to access the
Offset control:
There are 5 increments of frequency offset; with the search
coil held in the air, find the one for best stability.
Tip: EMI is easiest to hear in pinpoint mode (trigger
pulled).
Tip: If VX
3
continues to have erratic audio with the
search coil held in the air, reduce the RX Gain.
Menus & Controls
VX3 has a number of configuration settings with 2 ways to
access them:
• Live Control Bar — Live-search settings
• Menus — All settings, suspends operation
When the
Main Menu appears. We will cover all the menu settings in subsequent chapters.

Live Control Bar
You may want to quickly change settings while searching.
The Live Control Bar is displayed at the bottom of the Search
screen and its items are accessible via the left/right arrow buttons. When a Live Control item is selected (using the ENTER
button), a small control box pops up with one or more individual controls:
Any available setting in the Live Control Bar performs the
same function as any like-named setting in the menus, but the
live controls can be adjusted while the detector is in normal
operation. For many of the Live Control items, you can press
the VIEW button to access menus with additional settings and
controls. Accessing these menus suspends the search operation
of VX3.

Tip: Press VIEW+DN and VIEW+UP to hide or expand the
Live Control Bar.
Main Menu
While the Live Control Bar and its menus contain all of
VX3’s configuration settings, they are rather spread out. The
Main Menu pulls all the settings together in one easy-to-navigate linear list. The Main Menu can be accessed by pressing
MENU from the Search screen. To exit back to the Search
screen, simply pull the trigger switch. When you re-enter the
Main Menu VX3 will remember where you were last, even if
after a power down.

Controls
VX3 uses a variety of different interface controls such as
sliders and radio buttons. Most of them are very similar to those
found in computer graphical interfaces so they will be familiar
to many users.

VX3 Displays
VX3 has 2 display modes which are controlled by the posi-
tion of the trigger switch:
• Trigger neutral — Normal Search
• Trigger forward — All-metal pinpoint (no SAT applied)
• Trigger pulled — All-metal pinpoint (no SAT applied)
This section briefly describes the modes and their screens.
Chapter 5 has a more detailed discussion of display modes.
Search mode
Search mode is the normal display mode for VX3 and shows
a 3-frequency SpectraGraph1:
1. Programs which run in single frequency mode will display a sin-
gle frequency SpectraGraph.

User’s Guide
Along the top of the screen are the VDI number, icons, and
depth. The majority of the screen consists of the SpectraGraph
display, which provides real-time information on the target’s
VDI. See Chapter 5 for more information on how to read this
display.
Below the SpectraGraph is the Status Line, which contains
icons for the status of wireless headphones and backlight. In the
middle of the Status Line the name of the active Program is displayed, and is occasionally overwritten by the ground tracking
status.
At the bottom of the Search screen is the Live Control Bar
which gives instant access to the most common settings while
VX3 is operating.
Pinpoint mode
Pinpoint mode places VX3 in an all-metal mode and displays the Pinpoint screen:
Again, this screen has the depth (but no VDI or icons), Status
Line, and Live Control Bar. The Pinpoint display consists of 3

horizontal moving bars
which give the relative signal strengths
of the three frequencies. This can be used to precisely pinpoint
the target, and to see which frequency is giving the strongest

VX3 Audio
VX3 supports a built-in speaker, plug-in headphones, and
White’s proprietary wireless headphones. Headphones are
highly recommended as they help block out ambient noise,
making it much easier to discern the deeper target responses. If
you purchase the optional wireless headphones for your VX
see Chapter 8 for connect instructions.
Metal Detecting Basics
There are many excellent books available that cover the
hobby of metal detecting, and this manual cannot possibly do
justice to all the aspects of the hobby. Ask your dealer to recommend a good introductory book. We will, however, touch on a
few important topics.
Where to hunt
The basic rule of location is: the older the better. Old homes,
home sites, schools, parks, swimming holes, and picnic areas
can all yield great finds. However, “old” can also mean heavily
used, which can result in a lot of accumulated trash. The best
sites are those that have been “lost” or unused for decades.
Besides “old,” there are places which are constantly getting
replenished. With high gold prices, hunting for jewelry at
beaches can be very profitable, especially if it includes stones.
At parks and recreation areas, people often lay items on the
ground while they play sports, then lose or forget them.

Permission
This is CRITICALLY IMPORTANT! Over the years, a small
minority of inconsiderate detectorists have, in some places, created a negative image for the hobby (see the Treasure Hunter’s
Code of Ethics on the back cover of this manual). Do your part
to maintain a positive image: ask permission.
Private property always requires permission. Approach the
owner in a professional manner; some detectorists even make
up business cards. Be willing to offer the property owner a portion of the finds, especially if it’s a really choice site you’re
dying to hunt.
In many cities, homes have easements (the grass strip
between a sidewalk and street) which technically belong to the
city but are kept up by the homeowner. Assume it belongs to the
homeowner, and don’t hunt these areas without their permission.
Public lands have mixed access. National Parks are absolutely OFF LIMITS to metal detecting, and Park Rangers can
confiscate your detector and even your vehicle. Don’t even try!
State parks vary considerably, depending on the state and/or the
type of park. The best approach is to check with the Ranger Station responsible for the park.

Local parks and schools are usually open to detecting,
though some localities may require you to register. Find out
what the local laws are.
Detecting fundamentals
When you arrive at a hunt site, use your best intuition (and,
hopefully, research) to identify the most likely areas for good
finds. Often a site will be too large to cover 100% so you need
to narrow it down. If you are just learning, don’t be concerned
with patterns, just walk around and hunt. As you get proficient
with your detector and want to improve efficiency, you can
mentally grid off areas and hunt them in a back-and-forth pattern.
