5.6 Balance Switch
The Balance switch selects either Automatic Fast Track
or Automatic Slow Track, or the Fixed ground balance
position. In the two automatic positions the Eureka Gold
is an Automatic Ground Balance detector. This means
that the detector continually adjusts itself to maintain
ground balance, which will ensure that your detector is
Fast Track being the faster ground balance should be used where the
ground is heavily mineralised or changes rapidly. For ground which is more
mild or reasonably constant in its mineralisation, use the slower
Slow Track.
It is important to know that a deep target may be ‘balanced’ out by
continual sweeping over it when pinpointing in the automatic modes. By
ground balancing next to the target then switching to the Fixed mode, the
target cannot be balanced out. For the same reason the Fixed mode is
recommended when locating targets once dug from the hole.
5.7 Mode Switch (Disciminate/All Metal)
The Discriminate switch allows the use of
the discriminator built into the Eureka Gold.
It has two positions: All Metal and
Discriminate. In the All Metal position, the
detector responds to all types of targets with
the same target response.
In the Discriminate position, the detector discriminates between ferrous
and non-ferrous targets. The discriminator generally performs best on loud
signals. Its ability to Discriminate between ferrous and non-ferrous targets
may be affected by the depth and size of a target. Ferrous targets will be
signalled by a blanking of the audio threshold. Using the Eureka Gold
discriminating mode will not sacrifice sensitivity or depth, but it will not
necessarily discriminate to the full depth at which the target can be
detected.
searching to its greatest possible depth at all times. Fast Track causes
the ground balance to respond rapidly to changing ground conditions, while
the Slow Track setting responds at about half this rate.
