Rutus Argo NE, User Manual, Page: 12 / 22

No matter what mode of operation we use the detector, there are settings which are
common to all operating modes of the detector.

Frequency 6.6 kHz, 16 kHz
Frequency shift -2 to +2
Hot Rock -30 to +30
Backlight 0 – 29
Volume 1 – 30
Wireless Off, Ch 1, Ch 2

Frequency
The user has two operating frequencies: 6.6 kHz and 16 kHz. The higher frequency is
designed to search for very fine, thin objects such as jewelry and very fine coins. Iron masking
at 16 kHz is low. The 6.6 kHz frequency is a universal frequency - it can be used if the purpose
of the search is not for small items.
NOTE: After each Frequency change the detector requires the ground balance procedure to be
repeated.
Frequency shift
The Frequency shift gives you the ability to slightly separate the detector's operating
frequency to compensate for electromagnetic interference - for example when another metal
detector is operating nearby.
NOTE: After each Frequency shift change the detector requires the ground balance procedure
to be repeated.
Hot rock
This adjustment allows the detector’s reaction to magnetic rocks and objects of
particularly high identification value to be modified. Magnetic rocks are plain field rocks which
have residual magnetic properties. Magnets do not attract them, but they influence the
detector’s operation. They are essentially recognized by the detector as signals with an ID value
of -90 and in most cases these objects can be isolated using the discrimination option, in the
same way as simple steel scrap. Objects with exceptionally high ID values (+89 or +90) are
large pieces of aluminium, aluminium sheets and aluminium canteens. In this way Hot rock
adjustment can be used to set the reaction to objects at both ends of the identification scale.
This is a result of the detector „virtually” connecting both ends of the scale. The microprocessor
does not treat the identification scale as linear, but rather circular, where values of -90 and +90
are connected, and therefore an object identified as above -90 is automatically identified as a
high value object and vice versa.
