The MP
Digital is a high powered metal detector designed for the
X
serious treasure hunter. Using special advance circuitry, automatic
operation along with the ability to see further in the ground the MP
will achieve depths at up to 20% deeper, through the use of surface
mount technology. This MP
X
series also uses more power in the
searchcoil which in turns "pushes" the signal deeper in the ground.
Exclusive Features of the MP
• State-of-the-art surface mount technology.
• 20% more depth then the standard model.
• More power in the searchcoil that pushes the
signal deeper.
FEATURES —
1. Use the Target ID to learn what you've found.
The detected objects are shown on the large LCD meter.
You can determine immediately whether the objects are
worth digging, or not.
2. Use the Bar Graph LCD to locate your target fast!
3. Fully automatic with no tuning or ground balancing
required.
4. State-of-the-art adjustable Icon Target identification
system.
5. Unique Tone for Targets.
When an object is being detected, a unique tone correspond-
ing to the target will be heard. Therefore you don't have to
keep watching the LCD display while searching.
6. Auto-low battery voltage indication.
The Battery Icons will be displayed on the LCD when the
battery voltage goes below the proper value. In this case,
the batteries should be replaced at once.

Air Test - A sensitivity test performed by
outwardly moving various sized metal
X
samples under the metal detector search-
coil to measure the distance limit of detec-
tion. This test is not always an accurate
indicator of ground depth penetration
capability. (see Bench Test)
Alkaline - A class of battery characterized
by the ability to sustain longer periods
of current drain and greater storage life
when compared to the standard carbon-
zinc type.
Bench Test - An air test to determine at
what discriminate settings various metal
samples are rejected or accepted. The test
is conducted in a non-metallic area.
Cache - Any intentionally buried or se-
creted hoard of valuables.
Conductivity - The measure of a metal
target's ability to allow eddy current gen-
eration on its surface.
Control Housing - A metal or plastic box
which holds circuit boards, indicators, me-
ter, controls and power supply.
Depth Penetration - The greatest mea-
sure of metal detector ability to transmit an
electromagnetic field into the soil matrix
and produce a target signal.
Discrimination
which ignores or nulls audio responses
from a specific conductivity range allow-
ing positive responses to be heard from
metals higher in conductivity above the
discriminate control setting. Designed
primarily to eliminate audio response from
trash metals.
Double Blip - A signal characteristic com-
mon to elongated ferrous targets such as
nails detected in the all-metal non-motion
mode.
Faint Signal - A sound characteristic of
targets that are sometimes deeply buried
or very small in size.
False Signal - An erroneous signal cre-
ated by automatic retuning overshoot,
ground voids or highly mineralized hot
rocks.
Ferrous - Descriptive of any iron or iron
bearing material.
GLOSSARY OF TERMS
Metal - Metallic substances; iron, foil,
nickel, aluminum, gold, brass, lead, cop-
per, silver, etc.
Metal Detectorist - A person operating
a metal detector in the field. This name is
preferred by many over Treasure Hunter.
Mineralized Ground - any soil that
contains conductive or non-conductive
components.
Motion Discriminator - A detector type
that requires searchcoil motion to activate
its simultaneous ground balance and dis-
criminate functions.
Non-Ferrous - Not of iron. Metals of the
precious class (i.e. gold, silver, copper,
etc.)
Pinpointing - Finding the exact target
location with respect to a searchcoil's des-
ignated center. Accomplished by interpret-
ing the centers of audio response width in
perpendicular direction or scans.
Searchcoil - A circular (can be other
shapes) plastic housing containing single
or multiple transmit and receive windings
in a specific orientation or configuration to
emit and receive signals from ground and
targets. (also called loop or coil).
- Adjustable
circuitry
Searchcoil Cable - An electrostatically
shielded cable of conductors (wires) which
convey signals to/from the searchcoil or
control housing.
Sensitivity - The measure or capacity of
a metal detector to perceive changes in
conductivity within the detection pattern.
Generally, the more sensitivity a detector
can smoothly provide, the more depth it
will achieve.
Signal - An audio response or visual in-
dication alerting the operator that a target
has been detected.
Slow Motion - A description of searchcoil
speed required to operate the motion dis-
criminate mode.
Sweep - the motion one employs in mov-
ing the coil.
