INTRODUCTION
The Pulse 8X is one of the finest hand-held metal detectors manufac-
tured today. The Pulse 8X is used by commercial divers, US and foreign
military, law enforcement and dive rescue groups worldwide.
HOW PULSE DETECTORS WORK
Pulse detectors operate by transmitting a continuous stream of high en-
ergy electromagnetic pulses (one hundred per second), from the coil. After
each pulse is transmitted, the detector then “listens” using the coil as the
receiving antenna.
When a transmitted pulse hits a metal object, a magnetic field is induced
in the object. This causes eddy currents to flow in the metal, which in
turn generates a second magnetic field. This field is picked up by the
coil, amplified, and then displayed by the meter and heard in the speaker/
earphone.
Almost all metals are detectable by pulse induction. Stainless steel bolts
are not, but stainless steel props are (high iron content). The shape of the
metal can also influence its detectability. Almost any shape of target is
detectable except small loops of metal such as those used in a necklace.
Larger loops, such as rings are detectable. Alloy content of rings can
vary the detection range.

NOTE 2: When changing the battery, if any of the white plugs be-
come disconnected from the electronics board, reconnect the plugs
making sure that the mark on the side of the plug lines up with
mark on the electronics board.
- Insert the screws and snug up. DO NOT OVER TIGHTEN.
- Make sure o-ring is visibly compressed all the way around.
Optional Cable Connector and Coils
An underwater connector on the coil wire is available. It allows the coil
to be disconnected from the electronics housing. This enables field chang-
ing of different size coils. The available coils are: 5”, 7.5", 10", 16", 18"
with 100' of cable, 8" x 48" oval with skids and 100' of cable, and hand
held 1" probe (for pushing into sand/mud). When swapping coils on the
detector, be sure the o-ring is in place (in the housing side of the connec-
tor) and the locking ring is turned fully clockwise until it stops. The o-
ring size is 1/2" OD x 3/32" W. If water drops are present in either side of
the connector, allow it to air dry or use compressed air to dry before
reassembling.
MAINTENANCE
Your Pulse 8X was designed to be maintenance free. It is constructed of
corrosive resistant materials. However, as with most diving equipment,
it is recommended that it be rinsed in fresh water after use and stored in a
cool, dry place.
LIMITED WARRANTY
Your detector underwent constant inspection during assembly to insure
many years of trouble free performance. The PULSE 8X is warranted for
TWO FULL YEARS from the date of purchase. During this period, your
detector will be repaired free of charge should a failure occur due to
materials or workmanship. The warranty does not cover broken or cut
cables, broken shafts or coils, or damage due to dropping or general mis-
use.
Should service be required, write or phone us explaining the nature of
the problem, and we will provide shipping instructions. All repairs are
made at our factory. Repairs by unauthorized persons may void the
