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.

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.

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.
