TROUBLESHOOTING
TROUBLESHOOTING GUIDE
SYMPTOM CAUSE
Detector chatters • Using detector
or beeps erratically indoors
• Using detector near • Move away
power lines
• Using 2 detectors in • Keep 2 detectors
close proximity
• Highly oxidized
buried object
• Environmental
electromagnetic
interference
Constant low tone • Discharged batteries • Replace batteries
or constant repeating • Wrong type of
tones batteries
LCD does not lock • Multiple targets
on to one Target-ID present
or detector emits • Highly oxidized
multiple tones target
• Sensitivity set
too high
No power, no • Dead batteries
sounds
• Cord not connected • Check connections
securely
Detector sounds • Ground Balance

coil is lifted away
from ground.

SOLUTION
• Use detector
outdoors only
from power lines
at least 20' apart
• Only dig up
repeatable
signals
• Reduce sensitivity
until erratic
signals cease
• Use only 9V
alkaline batteries
• Move coil slowly
at different angles
• Reduce sensitivity
• Replace batteries
• Move Ground
Balance knob
counter-clockwise
• Re-ground balance

TERMINOLOGY

The following terms are used throughout the manual, and are standard
terminology among detectorists.
ELIMIN TION -
Reference to a metal being "eliminated" means that the
detector will not emit a tone, nor light up an indicator, when a
specified object passes through the coil's detection field.
DISCRIMIN TION
- When the detector emits different tones for different
types of metals, and when the detector "eliminates" certain metals,
we refer to this as the detector "discriminating" among different
types of metals.
Discrimination is an important feature of professional metal
detectors. Discrimination allows the user to ignore trash and
otherwise undesirable objects.
NOTCH
- Notching is the elimination of an item, or range of items, within
the metallic spectrum. We "notch-out" an object, or objects,
selectively. Objects to the left and right on the metallic spectrum
can be retained using the notch technique.
RELIC
- A relic is an object of interest by reason of its age or its association
with the past. Many relics are made of iron, but can also be made
of bronze or precious metals.
IRON
- Iron is a common, low-grade metal that is an undesirable target
in certain metal detecting applications. Examples of undesirable
iron objects are old cans, pipes, bolts, and nails.
Sometimes, the desired target is made of iron. Property markers,
for instance, contain iron. Valuable relics can also be composed of
iron; cannon balls, old armaments, and parts of old structures and
vehicles can also be composed of iron.
FERROUS
- Metals which are made of, or contain, iron.
PINPOINTING
- Pinpointing is the process of finding the exact location of a
buried object. Long-buried metals can appear exactly like the
surrounding soil, and can therefore be very hard to isolate from
the soil.
PULL-T BS
- Discarded pull-tabs from beverage containers are the most
bothersome trash items for treasure hunters. They come in many
different shapes and sizes. Pull-tabs can be eliminated from
detection, but some other valuable objects can have a magnetic
signature similar to pull-tabs, and will also be eliminated when
discriminating out pull-tabs.
GROUND B L NCE
- Ground Balancing is the ability of the detector to
ignore, or "see through," the earth's naturally occurring minerals,
and only sound a tone when a metal object is detected. The
Discovery 3300 incorporates proprietary Super-Scan™ circuitry to
eliminate false signals from severe ground conditions
