ASSEMBLY INSTRUCTIONS -
1. Remove all parts from the shipping carton and check assembly page to
make sure all parts are present.
2. Install black rubber washers on fiber clevis/lower rod, insert clevis lower rod
onto loop ears. Use only nonmetallic washers, fiber bolt, and fiber thumbnut to
secure loop/search coil to clevis/lower fiber rod.
3. Unlock “S” rod cam-lock and insert clevis/lower rod into curved “S” rod so
that stainless steel spring clip buttons line up and lock into one of the adjustment holes in the curved “S” rod. Turn cam-lock to secure. The second or third
adjustment holes are suitable for average sized adults. Individuals six feet or
taller should use fully extended position. Individuals well oversix feet tall should
purchase the optional Tall Man Rod accessory.
4. Unravel loop cable and wind the cable around the clevis and rod assembly,
first revolution over the top of the rod. Wind cable all the way to the top of the
curved “S” rod, about five revolutions. Use the black cable retainers, one near
the loop, and one near the top of the curved “S” rod, to hold the loop cable in
place.
5. Unlock control box rod cam-lock and insert curved “S” rod so that stainless
steel spring clip buttons line up and lock into the rod on top of the control box.
The “S” rod is designed to curve up towards the display. However those who
prefer to sweep the loop close to their feet may desire to assemble the “S” rod to
curve down towards the ground. Turn cam-lock to secure. Plug loop connector
into control box, screw lock ring to secure.
6. Grip the instrument by the handle, with your arm in the elbow cup with strap
and sweep the loop/search coil over the floor. If the instrument fit feels uncomfortable, readjust clevis/lower rod length with spring clip button and cam-lock so
that search coil can be held near the floor without requiring stooping over.
7. Remove the protective paper from the two black arm cup foam pads.
Carefully align pads on the inside of the elbow cup, one on each side of the
center rod, and press firmly into place.

8. 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. The elbow cup strap provides extra leverage and control. However,
some prefer not to use it.
9. Install battery as described in next section.
10. It should be noted at this point that the detector may not work as expected
indoors due to the high degree of metal used in modern construction. It is best to
tune and practice out-of-doors to ensure stable, predictable results. Additionally,
freshly buried targets will rarely produce the normal depth results of targets that
have been naturally lost and settled in undisturbed ground. Due to the abnormality caused by digging a hole in the ground matrix, and the lack of the normal
target to soil reactions, it may take a number of years for freshly-buried targets to
respond at true depths. The best way to determine true detection depth is in real
search conditions.
11. Hip Or Chest Mounting a) On top of the control box, the rod-to-case mounting plate has four
Phillips head screws. Remove these four screws and remove the rod/loop/arm
cup assembly from the top of the control box. To prevent moister/dirt from
entering the control box, replace the four screws on top the control box (sink all
the way) without the rod or mounting plate.
b) Adjust/unravel enough loop cable wrapped around the rod, to allow
slack to sweep the rod/loop and connection with the control box. Use two velcro
straps provided to secure loop cable around rod.
c) The control box can be worn on ones chest, hip, or waist based on
personal preference. Belt hook provided on bottom of control box as well as
four “D” rings to attach camera/dog leash connector type straps.

ENGINEERING DESCRIPTION -
Although the new Pulsescan TDI was designed with the Gold Prospector in mind, its features and performance will be just as valuable to Beach & Relic
Hunters.
During the development of the PulsescanTDI, we kept in mind the
comfort of the user by designing an instrument which would be as light as possible, and easy to operate in addition to producing outstanding performance at an
affordable price.
The Pulsescan TDI is a deep searching, very sensitive pulse induction metal detector which incorporates a true user controlled manual ground
balancing feature, a byproduct of which is the ability to produce an audio tone,
for possible identification of the detected target. User controlled manual balancing of the ground has the additional benefit of giving the user the option of fine
tweaking for different situations, thus increasing the probability of hearing the
faint signals of small or deep targets. The Manual Ground Balance feature of
the Pulsescan TDI can be turned off if the ground mineralization is not severe
enough to require it, as then the pulse circuitry itself is able to ignore most
ground mineralization by its very nature. In this situation, with the Ground
Balance toggle off, there is no audio tone variation - all metal targets will sound
alike, and additional depth can be attained.
White’s is proud to have been able to work with Eric Foster, of Oxford,
England, who enjoys the world wide reputation of being the “Father of Pulse
Technology”.

CHARGING SYSTEMS, BATTERIES AND BATTERY CONDITION -
Batteries and Charger
The PulsescanTDI uses a rechargeable Lithium Ion battery pack as the power
source. This type of battery can supply the high current levels required by the
detector and weights much less than other battery packs that have the same
power characteristics. It supplies a nominal voltage of 14.4 volts and approximately 500ma of current to the detector during operation.

The Smart Charger (Part Number 509-0040) used for recharging the Lithium Ion
batteries is supplied with the detector. It has two internal lights that indicate the
status of the charge cycle.

AND RECHARGE
PulseScan TDI Owner’s Guide 9
To recharge the battery:
1) Connect the battery pack to the charger and plug the
charger into the A.C. outlet.
2) The light in the charger will flash RED-GREEN-RED-
GREEN. This is a self check that indicates the charger is
operating correctly.
3) The RED light then comes on to indicate the battery is
charging.
4) When the battery reaches full charge, a minimum of seven
hours, the light will turn GREEN indicating that the battery is
ready to use.
5) If the battery is left connected the light will start to cycle
between RED and GREEN. Unplug the charger and dis connect the battery.
6) Only use the charger indoors. It is not weatherproof.
7) Do not cover the charger.
8) Do not use the charger in an ambient temperature greater
than 140 degrees Fahrenheit or 40 degrees Celsius.
9) Remove the charger from the AC outlet before
disconnecting battery.
10) Charger or battery may get very warm during charging.
This is normal.
If the battery has not been used for a long period of time, it is a good idea to
recharge before use in the detector.

CONTROLS
POWER -
What it does
This traditional control turns on or off the POWER from the internal, chargeable,
Lithium Ion battery pack. The toggle switch incorporates a locking device to
prevent accidental movement off or on.
How to use it
The locking mechanism prevents this toggle from accidentaly being bumped.
This is particularly valuable while operating the various control knobs. Just lift the
spring loaded toggle to release the lock and move the toggle.
IMPORTANT -
You must LIFT the Power Switch to release the lock, and move the
toggle.
PulseScan TDI Owner’s Guide 11
THRESHOLD -
What it does
This control adjusts the threshold of the unit. This is the faint background hum
which is present during the normal operation of the Pulsescan TDI. This hum,
which is always present, is increased when the knob is turned clockwise.
How to use it
In most detectors, including the Pulsescan TDI, the threshold is adjusted to a
faintly audible level by turning the knob clockwise. Unique to the Pulsescan TDI,
it is best to adjust the threshold past the chatter point, so that the sound is reasonably continuous. Then adjust the headphone volume to a comfortable level.
