TONE ID AND TONE ROLL AUDIO
The
CSI Pro's
Tone ID feature produces three distinct
audible tones based on a target's metal type and conductivity.
Low-Tone:
Ferrous targets such as nails, iron,
steel-core projectile, etc.
medium-Tone: Small, thin targets that are non-ferrous,
including many lead bullets, foil, and some
smaller brass, such as a .22 casing.
High Tone:
Non-ferrous targets with medium to high
conductivity, including larger brass and
copper bullets and casings.
The
CSI Pro
's advanced audio features allow the operator
to hear a target's size and depth via the Proportional Audio
and conductivity changes via Tone Roll Audio. more audible
target information helps the operator to identify targets,
particularly flat iron objects such as bottle caps and washers.
Garrett's Tone Roll Audio provides a variance of target tones
as the searchcoil approaches and passes over such iron
targets. These varying tones of audio provide better overall
target information to help avoid digging undesired iron
targets.
knives and guns made primarily of steel may produce any
of the three above audible tones based upon the size of the
object and its orientation in the ground. Scan several test
targets to better understand what tones they can produce.
(See "Iron Audio" section, pp. 31–33, for details on using
the Iron Audio feature to better identify undesired iron trash
items.)
