Depth Reading
Located in the center of the meter is a vertical bar (G), which predicts the likely depth of the
target. On shallow targets, the cursor is very high or close to the top, and the bar becomes almost
fully shaded, whereas for deep targets the cursor is quite close to the bottom, and the bar is
only partially filled.
The full depth of the bar is equal to 12" plus, meaning that the
target will be greater than 12" deep. If the bar is only half
shaded, the depth of the target is likely to be about 6" deep.
Information on the target’s depth is very useful if detecting in
sensitive areas like sports grounds or parks. By using the depth
meter you can concentrate on a specific depth of the soil, which
can improve your success rate.

Overload
If the target is too big or too close to the coil to be classified, the word OVERLOAD will appear on
the display screen. This is accompanied by a rapid continuous buzzing sound. Detect the target
again by lifting the coil slightly higher and you will often get an accurate response.

Detect Modes
There are four factory pre-set ‘Detect’ modes and four save modes available for searching.
Each mode is customized with the optimum settings, to allow you to find the types of objects
described by the detect mode name. The four detect modes are:
- Coin (3a) - Relic (3c)
- Coin/Jewelry (3b) - All Metal (3d)
In some locations, there may be a specific pattern to the type of targets found in the area. For
example, an old house or building site may have certain areas where a certain junk type has been
concentrated, or other areas where it is more likely coins have been lost. On the beach, foil and
modern coins are more plentiful on the dry sand, whereas less junk and more gold jewelry are
located on the wet sand.
Due to the different types of targets you may expect in certain areas, you will often prefer a
different discrimination pattern for each area. With the Minelab Quattro MP, you have the choice
to search in one of the factory pre-set discrimination patterns, or you can create and save your
own patterns to suit the different areas you commonly search.
Start – Up
On the initial start-up, your detector will default to the factory COIN Mode.
To select a different factory pre-set Detect mode, press and release the appropriate mode button.
The icon (H) next to the corresponding preset mode, indicates that a factory preset mode has
been selected. The detector will apply the factory determined discrimination pattern, and audio
response for that mode.
QUICK START:
Simply turn on the Quattro MP by pressing the POWER button (1), select one of
the four preset modes (3a; b; c;or d), press the NOISE CANCEL (8) and you can commence
detecting straight away.

3.1.
Coin Mode
This mode has an "accept/reject" or "discrimination" pattern that is best for ignoring a variety of
junk targets, while still being able to detect most coins. One of the features of the Quattro MP
is its ability to vary the tone on the target signal. In COIN mode the Audio signal/tone will vary
according to the level of conductivity of the detected metal. Eg: Highly conductive metals like
silver, gold and brass will produce a high pitch signal. Lower conductive items like foil, nickel, and
low carat jewelry will produce a lower tone.
(see Section 10 : Detector Sounds).
The reject settings for this mode are (–10 to +2) and (+6 to +8).
Use: This mode is best used in high trash areas such as modern parks, sporting grounds,
playgrounds, busy beaches etc. and, will ignore a large percentage of foil and ferrous trash.
Note: Some modern coins are produced with nickel or steel cores and should be considered in
certain regional applications. These coins may not be detected in COIN Mode.

3.2.
Coin/Jewelry
This mode has a slightly reduced level of "rejection" or "discrimination" to enable you to locate
non-ferrous (iron) coins, as well as gold jewelry. It allows some coins with a high ferrous content
or low carat jewelry, that may have been discriminated in COIN mode to be detected, however
aluminium foil will also be detected. The audio signal response will vary depending on conductiv-
ity in the same fashion as the COIN mode.
The pre-set reject settings for this mode are (–10 to –1)
Tip: Low tone = Low Conductivity content. High tone = High Conductivity content.
Use: The most common use for this mode is for those who are prepared to dig some foil and pull
tabs to find all gold jewelry, ideal for beaches, old parks, abandoned house sites, camps etc.

3.3.
Relic
The RELIC mode has an even lower level of "rejection" or "discrimination," as many rare and
valuable relics can have very low conductivity and/or ferrous content. The Audio response in
RELIC mode is different to the COIN, and COIN/JEWELRY modes in that it uses the ferrous (iron)
content to determine the pitch of signal.
Note: Depending on which mode you select , a beep
and icon will appear briefly which will indicate which
mode the audio response is in. This is shown as:
In this RELIC mode, a target with a high ferrous content will produce a low tone and objects with
a low ferrous content give a high tone.
The pre-set "reject" or "discrimination" settings for this mode are (–10 to –3). Because of this,
beach hunters who specifically target gold jewelry may also prefer to use the RELIC mode.
The other difference with the RELIC mode is that the pictorial on-screen
icons are not shown, as
operators using this mode are more likely to interpret signals using the ID numbers and audio
response only.

All Metal
ALL METAL mode is similar to the RELIC mode, the difference being that no discrimination is used.
