Preset:
Placing the TUNER to (Preset). AUTO GEB
(automatic ground exclusion balance) to GND
AUTO TRAC (ground automatic tracking), and the
MODE to the HIGH, good results will be achieved
in average conditions. However, it may be neces-
sary to fine tune the detector for use in other than
average ground, or simply to maximize perfor-
mance for a specific type of searching. These preset
positions are intended to offer generally acceptable
settings. Most anxious detectorists prefer to venture
out and use their new detector for the first time
before they have carefully read this manual. The
allows such use with surprising success. After
use, the SIERRA MADRE will eventually fine
tune its own ground rejection through tracking,
thus improve its performance automatically. It has
also been found that becoming proficient using
the detector at the settings eases the learning
curve, making further study a smoother and more
enjoyable experience.
Keep the loop sweeping from side to side very
close to the ground, always moving. Those using
a detector for the first time often sweep the loop
too slowly; a brisk sweep of about two seconds for
each pass is desirable.
Overlap each pass by at least 50%.
Metals produce a solid abrupt “beep”. The meter
deflects positive (to the right) in unison with the
sound “beep”. Sweep the loop over the area several
times. Once the decision has been made to dig,
slowly “X” the loop over the area to pinpoint
its exact location. The strongest sound and furthest
meter movement to the right
indicate target center.
