OWNER’S MANUAL
The
Discovery 1100 is
an easy to use detector.
The most difficult aspects of
metal detecting have been automated.
However, if you are new to the hobby,
we strongly recommend that you:
1) Adjust the Sensitivity to a low setting
in the event of false signals. Always begin
use at a reduced sensitivity level; increase to full
sensitivity after you have become familiar with the
detector.
2) Do not use indoors. This detector is for outdoor use only. Many
household appliances emit electromagnetic energy, which can
interfere with the detector. If conducting an indoor demonstration,
turn the sensitivity down and keep the searchcoil away from
appliances such as computers, televisions and microwave ovens.
If your detector beeps erratically, turn off appliances and lights
(especially those with dimmer switches).
Also keep the searchcoil away from objects containing metal, such
as floors and walls.
3) Read this manual. Most importantly, review the Quick-Start Demo
(p.7) and Basic Operation (pp. 9-12).
4) Use 9-volt ALKALINE batteries only. Do not use Heavy Duty
Batteries.

TERMINOLOGY
The following terms are used throughout the manual, and are standard
terminology among detectorists.
ELIMINATION
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.
DISCRIMINATION
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.
RELICA 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-TABS
Discarded pull-tabs from beverage containers are the most
bothersome trash items for treasure hunters. They come in many
different shapes and sizes. Most pull-tabs can be eliminated with
the Mode Control, 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 BALANCE
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.

ASSEMBLY
Assembly is easy and requires no tools.
●
1Position the lower stem (the straight
tube) with the silver button toward the
back.
Using the bolt and knurled knob,
attach the searchcoil to the
plastic extension
protruding from the
lower stem.
●
2Press the button
on the upper end
of the lower stem,
and slide the lower
stem into the upper
stem.
Adjust the stem to a length
that lets you maintain a
comfortable upright
posture, with your arm relaxed at your side, and the
searchcoil parallel to the ground in front of you.
●
3Wind the cable securely around the stem.
●
4Insert the plug into the
matching connector on
the right underside of the
detector body. Be sure
that the key-way and
pins line up correctly.
Caution: Do not force the
plug in. Excess
force will cause
damage.
To disconnect the
cable, pull on the
plug.
Do not pull
on the cable.

Adjusting the Armrest
Most people will find the standard
position of the armrest very comfortable.
Very large forearms and short forearms
(particularly children’s arms), can be
accommodated by moving the armrest
forward.
The armrest may be moved forward or
backwards by removing the single
screw and nut, and then repositioning
the 2-piece armrest. Users with shorter
arms may find the armrest more
comfortable in the forward position. In
order to move the armrest backwards,
the plastic plug must be removed from
the aluminum tube.
Armrest Strap
(optional accessory)
The strap is available for purchase as a
separate accessory. Some users prefer
to use the strap when swing the detector
vigorously, in order to hold the detector
secure against the arm.
The detector can also be used without
the strap, with no compromise to
detector balance and stability under most
conditions.
6
Use ALKALINE
batteries only.
To install the
batteries:
●
1Remove the
battery cover by
disengaging the
clip at the back.
●
2Align the polarity
of the batteries
correctly, with
the positive "+"
toward the coil
plug connection,
as indicated by
the + and –
indicators on the
housing.
●
3Insert (2) 9-Volt ALKALINE batteries, with the contacts pointed inward,
and press down on the back of the batteries to snap them into place.
Some brands of batteries will require moderate force to clear the
retaining tabs.
●
4Replace the battery door.
The Low Battery Indicator will come on and stay on if the batteries need
to be replaced.
Most metal detector problems are due to improperly installed batteries,
or the use of non-alkaline or discharged batteries. If the detector does
not turn on, please check the batteries.

BASIC OPERATION
POWERING UP
Press the ON touchpad.
All display indicators will illuminate momentarily.
The 4-segment pyramid-shaped Sensitivity Indicator will illuminate on
the left side of the display. The 4-segment pyramid indicates that the
detector is at full sensitivity.
When an object is detected, the object will be identified by a tone, a
display indicator, and a depth indication.
A two-minute “warm-up” is required before the detector reaches full
sensitivity.
UNDERSTANDING THE DISPLAY
The LEFT SIDE of the display has a dual purpose:
●
1SENSITIVITY LEVEL
Upon power-up, and after
pressing either the up- or
down-sensitivity pads, the
pyramid-shaped display
indicates the detector’s
sensitivity level.
The sensitivity level can be
changed using the up- and down-pads.
At maximum sensitivity, the unit can detect a coin-sized metal object
buried about 6" beneath the surface; larger objects can be detected
much deeper.
●
2DEPTH INDICATION
After detecting an object, the
pyramid-shaped display
indicates the approximate depth
of buried, coin-sized objects.
Objects at or near the surface
will illuminate the single
segment at the top of the
scale.
More deeply buried objects will illuminate more segments, indicating
depths of 2, 4, or 6 inches, as identified to the left of the display.
The depth indicator is not accurate for large, or irregularly shaped, objects.
However, the scale will provide relative depth indications for larger objects; a
given object will induce deeper readings the farther it is from the searchcoil.
10
BASIC OPERATION
The RIGHT SIDE of the display classifies objects into three categories.
Silver/Copper: ------------------------------------------
Objects composed of silver and
cooper will illuminate this arrow.
Buried and heavily oxidized metal
objects, such as old tin cans, can
also fall into this category. Larger
aluminum objects, like beverage
cans, will sometimes fall into this
category.
Mid-Range: ------------------------------------------------
Mid-range objects cover a large
variety of metals.
Among them are: pull-tabs from
beverage containers, nickels,
medium-sized gold objects, some
types of aluminum, and zinc.
Iron: -------------------------------------------------------------
All ferrous objects, and some
smaller aluminum objects, fall into
the iron category. Small gold
objects can also fall into this range.
The BOTTOM RIGHT SIDE of the
display will illuminate a Low Battery
Indicator symbol if the batteries are
discharged. The indicator illuminates,
and remains illuminated, when the
9-volt batteries have discharged to a
level of 7.35 volts.
Reading the Display IN THE FIELD
With the detector in use in the field, the display will indicate both the DEPTH
and the TARGET IDENTIFICATION of each object detected. After a target is
detected, these indicators will remain illuminated with this information until
the next target has been detected. If uncertain about the target’s
identification, try sweeping the coil at a faster speed. A more rapid sweep
over a target will generally provide a more accurate target identification.
