Assembly Instructions
1. Remove all parts from shipping carton and
check the assembly page to make sure all parts are
present. Remove control box from the “S” rod by
compressing both the spring clip buttons on one
side of the rod and pivoting the control box off.
For superior water proofing, the Loop, Headphone, and their cables are hard wired (not removable) from the control box, headphone and loop.
The waterproof fitting and strain reliefs on the
cables are torqued to a specific ideal setting and
should not be loosened or tightened. Extra care/effort must be taken in assembly regarding winding
the cable around the rod.
2. Unlock “S” rod camlock and insert the reduced
end of the center rod into curved “S” rod so that
stainless steel spring clip buttons line up and lock
into the holes in the curved “S” rod. Turn camlock to secure.
3. Fit the rubber washers between clevis/lower
rod and searchcoil ears. Use only non-metallic
washers, fiber bolt, and thumbnut, to secure loop
to clevis/lower rod. Then insert into center rod so
that stainless steel spring buttons line up and lock
into one of the adjustment holes in the center rod.
Turn Camlock to secure.
4. Unravel cable and wind the cable around the
clevis and rod assembly, first revolution should be
OVER the top of the rod with some slack before
applying the cable retainer. This is done so that
the search coil can be paddled backwards toward
the rod without putting a strain on the cable. Wind
cable firmly all the way to the curve in the “S”
rod. Then attach control box to the rod by compressing the two spring clips on the rod aligning
and inserting control box lid bracket. To secure
cable, wrap velcro cable retainers around rod and
Chapter 1 Surf Dual Field Assembly
cable, one near the searchcoil and one near the
padded handle on the “S” rod.
5. Grip the instrument by the handle, with your
arm in the elbow cup with strap secure, and sweep
the coil over the floor. If the instrument fit feels
uncomfortable, readjust clevis/lower rod length
with the sping clip buttons so that the searchcoil
can be held near the floor without requiring stooping over.
6. Adjust the elbow cup strap so that it is loose
enough for you to slide your arm in and out without loosening each time you want to set the detector down. Peel and stick elbow cup foam pads on
the inside of the elbow cup, one on each side.
7. Install batteries as described in the next section.
8. This model can also be worn as a hipmount
simply by removing the control box from the “S”
rod, adjusting the length of cable wound around the
rod, and weaving your belt through the slots on the
bottom of the control box.
9. It should be noted at this point that the detector
may not work as expected indoors due to the high
degree of metals ( nails, pipes, etc.) used in modern
construction and the presence of electrical interference. It is best to tune and practice out-of-doors to
ensure stable, predictable results.
10. The Surf Dual Field is designed to respond to
all metal types, no trash metal rejection.

Installing Batteries
The Surfmaster Dual Field is powered by eight AA
Penlight batteries. Alkaline cells are recommended.
Lift the latches on the sides of the case and remove
the lid, using care not to lose or damage the “O”
ring seal, located on the lid. Remove the battery
holder from the parts bag and install the penlight
batteries. Connect the battery lead to the pack and
put the pack into the case. Clean any dirt or sand
from the “O” ring, case and lid. Replace the lid, being sure it is seated properly. Close the case latches.
Look at the “O” ring to be sure it is compressed
and seated properly on the lower case surface.

Standard carbon-zinc or heavy duty batteries will
last for approximately 15 hours. Alkaline batteries are recommended and should provide 25 to 35
hours of continuous operation. Battery life will
vary with changes in temperature, number of target
responses, as well as battery type.
Testing Batteries
A battery test can be performed with the T-HOLD
control. When the T-HOLD is turned fully counterclockwise until it clicks, the audio battery tester is
turned on. The condition of the batteries is indicated by the volume of the “beep.” When the batteries
are new a loud “beep” is heard. The “beep” will become weak when the batteries need to be replaced.

Controls
Chapter 3 Surf Dual Field Controls
As the Pulse Timing Control is moved clockwise, it
increases the delay of the sample pulses that detect
targets, and reduces the ground noise from black
sand. However, if the control is increased too far
clockwise it will reduce the detectors's sensitivity for small jewelry and coins you should use the
lowest control setting required to minimize ground
noise.
THE TRIANGLE REPRESENTS
THE OPTIMUM SETTING THE
FACTORY RECOMMENDS FOR
MOST SEARCHING
GAIN
The GAIN control turns the power ON and OFF
and is used to select the responsiveness (sensitivity)
of the Surfmaster Dual Field.
High ground mineralization or electrical interference in the search area may require a decreased
level of Gain to stabilize responses to be both predictable and reliable.
Low mineralized areas and/or areas of little electrical interference may require increased levels of
Gain for the best performance. At the maximum
setting some instability may be expected depending
upon electrical noise in the area. The recommended
setting is the furthest clockwise setting that allows
smooth predictable responses.
Under most circumstances, you should dig every
signal. However when you find yourself searching
an area that is littered with bits of aluminum foil
you can advance the Pulse Timing Control to ignore
the foil and still detect shallow US nickels. At this
control setting you will lose deeper nickels and
some gold jewelry and the depth for other coins will
be reduced by about ten percent.
T-HOLD
The T-HOLD is used to adjust the background hum
(threshold). The threshold is the low hum you hear
when you are not detecting a target. The T-HOLD
should be adjusted so that you can hear a slight hum
(edge of sound). If the hum is set too loud, it may
mask some of the deeper targets. If it is set too low,
some of the deeper targets may not be heard. The
T-HOLD also functions as a sensitivity control.
Setting it for silent operation will reduce sensitivity eliminating noise from nearby detectors or other
electrical sources, however, some reduction in
detection depth can be expected.
PULSE TIMING
The Pulse Timing Control can be adjusted to reduce
the effects of mineralized ground that can cause
false target signals. The control is very useful in
minimizing ground noise on beaches containing
large amounts of black sand or regions with sand
derived from volcanic rock. If the ground does not
cause false signals the control should be set at minimum for optimum performance.
We could have made the threshold “preset” at the
factory. We chose not to because no two people
hear things the same way. When you are hunting in
dry sand in a quiet area, you can set the threshold
very low. If you are near the surf or in a noisy area,
you may have to increase it slightly to hear it.

Chapter 4 Surf Dual Field Operation
Operation
Background
The Surfmaster Dual Field has been enhanced with
increased performance over past Surfmaster PI
models. It is a high-performance user-friendly metal
detector, waterproof to an underwater depth of 100
feet, operating on the Pulse Induction principle. It
is capable of extreme detection depth on coins and
jewelry in salt water and mineralized ground. In
the past, P.I. metal detectors had to be swept very
slowly for maximum depth and they had very poor
sensitivity to copper-nickel coins and gold. They
had manual tuning which was critical to adjust and
prone to drift. Most used a VCO or "fire siren" type
of audio tone which changed from a low growl to a
squeal when a target was detected.
The Surfmaster Dual Field is different. It is the
result of over fifteen years of research and develop
ment. Our goal was to develop a Pulse Induction
metal detector which could match the sweep speed,
sensitivity, stability and ease of use of an Induction Balance VLF without responding to wet salt or
mineralized ground. The Surfmaster Dual Field may
be swept either quickly or slowly with virtually no
loss in sensitivity. It was designed to be more sensitive to gold and copper-nickel alloys than to other
metals.
-
Dry Sand Searching
The Surfmaster Dual Field operates on the Pulse
Induction principle. Unlike an induction balance
detector, it does not require any ground balance
adjustments. Most P.I. instruments must be swept
very slowly in order to achieve maximum depth, but
the Surfmaster Dual Field, does not. It was designed
to have a fast target response, so it can be swept
almost as quickly as an Induction Balance (VLF)
detector.
When you lower the loop to the ground, you should
not hear any change in the threshold tone. Mineralized ground might cause a slight response, but the
S.A.T. circuit will compensate for it. Sweep the
loop from side-to-side and listen for any increase
in the threshold tone. Try to keep the loop level
about one inch above the ground. Any repeatable
signal, no matter how faint, should be investigated.
The loop needs to be in motion continually during
searching.
The Surfmaster Dual Field loop field is shaped
somewhat like a half-circle rather than the more
familiar “V” or funnel. For maximum coverage,
you should overlap your sweeps by at least 50%.
Targets can also be detected outside the edge of the
loop depending upon their depth and position with
relation to the coil plane.
The Surfmaster Dual Field has fast Self-Adjusting
Threshold. Once the threshold tone has been adjusted, the S.A.T. system will maintain it. If you stop
the loop over a metal target, the S.A.T. will tune it
out and return the detector to the threshold tone. If
you move off the target, then back on, the detector will re-tune giving a response. For this reason,
the loop must be kept in motion while detecting or
pinpointing a target.
6
Chapter 4 Surf Dual Field Operation
The sweep speed affects the performance capability of the detector. If you sweep too slowly, the
S.A.T. will attempt to tune out a detected target.
The result will be a loss in depth. If you sweep too
quickly, the detector may not respond to a detected
target also resulting in a loss in depth. The optimum sweep speed is three to five feet per second.
In other words, if you sweep the loop in a five foot
swath in front of you, you should be able to count
“one-hundred-and-one.”

PINPOINTING
A TARGET BY
"X"ING
If you are searching an area
that has produced valuables, or
has the potential for producing
valuables, cover the area at least
twice. Search first in one direction and then again at a different
angle 90 degrees from the first.
Some targets, such as coins on
edge, may only respond from
one direction.
You may wish to bottom scrub the loop for maxi
mum depth. Scrubbing is not really necessary and
may cause false signals over highly mineralized
sand/silt. Scrubbing also causes wear on the bottom
of the coil and puts added stress on the coil connecting hardware. If you wish to scrub, you should
purchase a protective loop cover. Be sure to remove
the cover at regular intervals and clean out any sand
or water.
The search coil has a very wide scanning area.
When you hear a target, sweep slowly over it until
the response is equal as you move the loop back
and forth. Pinpoint by sweeping it from two directions, from back-to-back and side-to-side until the
response is equal in all directions. If you slow the
sweep, you can pinpoint with a good degree of accuracy. The most sensitive area of the loop is in the
center.
Shallow targets can be difficult to pinpoint if they
overload the coil. Simply raise the loop while “xing” the target area. Coins lying flat will usually
respond best in the exact center of the loop. Coins
on edge, nails and irregularly shaped objects may
tend to pinpoint near the outer edge of the loop. If
you have trouble locating the target, turn the loop
90 degrees and pinpoint with the edge.

Chapter 4 Surf Dual Field Operation
Searching in Salt Water
Pulse Induction instruments do not need to be adjusted to ignore the effects of wet salt or ground
mineralization. When you plunge the loop into salt
water, it will take a second or two for the S.A.T. to
stabilize the detector. If you lift the loop out of the
water, you will hear a brief tone.This is a normal
function of the S.A.T. system.
If you are hunting at the surf line, simply lift the
loop just above the water as the wave comes in.
This will minimize false signals, plus it is easier to
sweep the loop in air than in water. If the loop is
dunked in salt water, then pulled out and swept on
dry land some false signals may be heard. They are
caused by the water droplets moving around on the
loop case. You can minimize these noises by treating the loop case with Armor All, silicone spray,
or spray wax. This makes it easier to shake off the
sand and excess water.

Interpreting changes in the threshold is the key to
success using the Surfmaster Dual Field. Some very
deep targets could cause a subtle beep in the normal
threshold. Identifying these subtle changes can be
challenging underwater with noise from your air
supply. Practice with known targets to become familiar with the way the threshold changes over such
sample targets.
Some threshold changes are caused by dramatic
changes in the ground, for example placing the loop
in salt water. Obvious changes in conditions are
easily recognized and the Surfmaster Dual Field
will quickly and automatically reduce the sound
back to threshold. However, less obvious changes
may result in some conditions. Decomposed iron,
for example, may respond. Such signals must be
investigated. Fortunately some idea as to the size
of a target can be determined by the size of the area
that causes the change in threshold. Remember to
keep the loop in motion so that the instrument will
continue to respond.
Information
Proper Care
Cleaning
The entire Surfmaster Dual Field is waterproof and
submergible. It can be cleaned with fresh water
and a mild soap. After cleaning, dry the instrument
thoroughly.
Weather Conditions
Protect your detector from excessively cold weather. Freezing can damage the electronic components,
the case and/or the battery. Excessive heat can also
damage the instrument. Never leave it in the sun.
It's best to lay it in the shade when not in use. If it's
left in a car or boat on a hot day, cover it to protect
it from the direct rays of the sun, and then leave the
windows slightly open to permit ventilation.
Saltwater
Saltwater is very corrosive! After your detector has
been exposed to saltwater, rinse the loop and rods
in fresh water. Then wipe it with a cloth dampened
with fresh water, and dry it thoroughly.
Chapter 5 Surf Dual Field Information
Opening Control Box
When opening the control box, first make sure the
instrument is dry. Water, if allowed to contact the
circuit board, will damage it.
When opening the control box to replace the batteries, always make sure the “O” ring is free of dirt
or sand, and is properly positioned before the case
is closed. If this “O” ring shows any signs of wear,
replace it before using this instrument in the water. This "O” ring, Whiteʼs Part Number 527-0040
is a custom shape, and can be ordered from your
White's Dealer or Service Center. Failure to maintain the “O” ring properly will result in extensive
damage to the instrument, and will not be covered
under warranty. If traveling abroad or using this
model extensively, ordering additional “O" rings is
highly advisable. Professionals typically replace the
“O” ring once a year.
Storage
If you plan to store your instrument for any length
of time, unsnap the batteries and remove from the
instrument. Whenever your instrument is not in
use, turn the ON/OFF GAIN Knob all the way to
the left until it clicks off.
Travel
If traveling and expecting large variations in alti
tude, such as traveling through mountain passes,
disengage control box latches to allow equalization
of pressure.
