SEARCH MODES
8
SIMPLEX+ has 4 search modes designed for different terrains and targets. You can navigate between
the modes easily by using the right and left arrow buttons. The selected mode will be highlighted in
black.
All Metal
Different than the other modes, this mode features a threshold tone which is
continuously heard in the background. You cannot search in the All Metal mode
without ground balancing.
In this mode, the device does not discriminate targets and detects them all (metals, mineralized rocks
etc.). ID of the detected target is shown on the display (except for negative hot rocks) and the same
audio tone is provided for all targets. The audio tone increases in pitch as the coil approaches the
target.
The threshold tone in this mode is optimized to provide the best performance on different terrains and
cannot be adjusted. You can however, adjust the sensitivity setting based on ground and environmental
conditions.
As the sensitivity is lowered, the threshold tone gets weaker and cannot be heard at the lowest
sensitivity levels.
We recommend using the All Metal Mode when discrimination is not important and not using it in
heavy trash areas or areas containing many hot rocks.
Field
Recommended especially for relic hunting. It produces good results particularly on clean
sites which do not contain waste metal. More depth can be obtained on sites which are
rocky or trashy, by using the notch discrimination setting and swinging the search coil
more slowly (one right/left pass per approximately 1 second).
In this mode, the device produces a low tone for ferrous targets with IDs between 0-15. For non-ferrous
targets with IDs 16-99, it produces a higher tone which increases in pitch as the coil approaches the
target.
Park
This is the 3-tone discrimination mode designed for coin hunting especially in trashy
sites such as parks.
In this mode, the device produces a low tone for ferrous targets with 0-15 IDs, a medium tone for
gold and non-ferrous metals with IDs 16-42 and a high tone for non-ferrous metals with IDs 43-99
such as silver, brass and copper.
Beach
This is a special mode of the SIMPLEX+ developed for conductive grounds (salty wet
sand beach, grounds with alkali soil etc.). The feature of this mode presents the ability
to ignore iron and similar targets in this group and to be able to perform ground
balance on any type of ground. While the device performs ground balance in the
range of 20-99.8 automatically in the other discrimination modes, the device ground
balances in the range of 0-99.8 in this mode. This enables easier ground balancing
on conductive grounds where normally ground balance cannot be performed at all or
performed with difficulty.
Different than the other modes, targets with 0-15 IDs are notched out by default and cannot be
changed in order to ignore ferrous metals or ground noise. In this mode, the device produces a
medium tone for gold and non-ferrous metals with IDs 16-99.
Salt water and alkali grounds are significantly conductive due to high ionization and cause effects
similar to that of iron in detectors. These effects may make it impossible to search for metals with
a standard detector. Existence of an iron elimination feature in a detector can improve the situation
but may not be sufficient.
SIMPLEX+'s beach mode eliminates such effects and ground noise. Aspects to be taken into
consideration while searching on conductive grounds are explained in more detail in the section
titled Detection on the Beach and Underwater (page 17).
