Discrimination Modes (Two Tone, Three Tone, Beach, Deep)
Different than the All Metal mode, these modes do not have a background sound. The
device only provides a warning tone when a target is detected. A crackling noise can be
heard if gain is not at the right level in these modes. Therefore, the gain adjustment in
these modes should be performed in a location without metals and when the device is
silent.
Some of the features of the discrimination modes are similar, however, there are minor
behavioral differences between them. ID FILTER, NOTCH FILTER, IRON AUDIO and TONE
BREAK are frequently used common features in these modes. ID FILTER value is preset by
the factory for these modes. You can modify these settings if you want according to the soil
conditions where you are searching.
Two Tone Mode
It is the deepest mode after the DEEP mode among the discrimination modes. It is
recommended especially for relic and coin 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 contain waste metals by using the ID FILTER and NOTCH FILTER features
and swinging the search coil more slowly (one right/left pass per approximately 1 second).
ID FILTER value is set to 03 as a default value. You can modify this value according to the ID
of the target you don’t want to detect.
In the Two Tone mode, the device produces a low tone for ferrous targets with IDs between
0-10. For gold/non-ferrous targets with IDs 11-99, it produces a high tone which increases
in pitch as the coil approaches the target. By using the TONE BREAK feature, you can adjust
the break points of the target response tones on the TARGET ID range.
It is recommended that you perform tests with mineral rocks and different metals before
using the device in the field in order to get familiar with the warning tones of the device.
All Metal
It is the deepest mode of the device. Different than the other modes, this mode features a
threshold tone which is continuously heard in the background.
The device does not discriminate targets while in the All Metal mode and detects all
targets (metal, mineralized rocks etc.). ID of the detected target is shown on the display
(except for negative hot rocks) and the same warning tone is provided for all targets. The
warning tone increases in pitch as the coil approaches the target.
Gain, threshold and iSAT settings in this mode are set to default values which provide the
best performance on different terrains. You can modify these settings based on ground
conditions.
ID FILTER, NOTCH FILTER, IRON AUDIO AND TONE BREAK features not active in the All Metal
mode. Therefore, these settings cannot be selected in the menu.
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.
