C. GROUND EXCLUDE CONTROL
This control enables the user to select a mode of operation best suited to the site to be worked on,
for instance:
G 1 is the mode to be used on mineralised inland sites and can be used in conjunction with any of
the Simdisc modes described above depending on the nature of finds the user wishes to locate or
reject. With this setting the level of ground exclusion is pre-set.
G 2 is the mode best suited to beaches, but it can also be used on non-mineralised inland sites when
ground effect is not particularly serious but the rejection of iron is specifically desired. In this
setting, the user can finely adjust the level of ground exclusion required for wet salt sand by using
the "LEVEL" Control D.
D. LEVELCONTROL
This control is used in conjunction with the G 2 mode and acts as a variable ground exclusion
control to allow the user to accurately set the level of ground exclusion required on particular beach
sites, or allows adjustment to the rejection level against iron and small pieces of silver paper.
E. AUTO-TUNE BUTTON
The Auto-tune button is the control on the detector which is most frequently used. It must be
pressed and held whenever an alteration is made to any one of the four other controls and should
only be released once such alterations have been completed. It also acts as a memory retune button
and will, when pressed, recall the optimum tuning level should the detector drift out of tune due to
temperature changes, search head to ground level changes or when false signals are received. Please
note that the Auto-Tune button should only be released after initial tuning, mode changes etc. once
the search head has been lowered to the operational search height. Searching should always take
place with the Auto-Tune button released.
F. METER
1 . The meter will give a visual indication of the optimum tuning level when the needle is in the
central TUNE position.
2. When using the detector in the meter discriminate mode, it will show a negative response to
unwanted items (needle will swing to the left from its central position).
3. When pinpointing a target signal, full deflection of the meter needle to the right will indicate
that the object is situated under the centre of the search head.
4. The meter acts as a battery check - See G.
