BASIC OPERATION (continued)
The RIGHT SIDE of the display classifies objects into three categories.
Silver/Copper: ------------------------------------------
Objects composed of silver and
cooper will illuminate this arrow.
Buried and heavily oxidized metal
objects, such as old tin cans, can
also fall into this category. Larger
aluminum objects, like beverage
cans, will sometimes fall into this
category.
Mid-Range: ------------------------------------------------
Mid-range objects cover a large
variety of metals.
Among them are: pull-tabs from
beverage containers, nickels,
medium-sized gold objects, some
types of aluminum, and zinc.
Iron: -------------------------------------------------------------
All ferrous objects, and some
smaller aluminum objects, fall
into the iron category. Small gold
objects can also fall into this
range.
The BOTTOM RIGHT SIDE of the
display will illuminate a Low Battery
Indicator symbol if the batteries are
discharged. The indicator illuminates,
and remains illuminated, when the
9-volt batteries have discharged to a
level of 7.35 volts.
Reading the Display IN THE FIELD
With the detector in use in the field, the display will indicate both the
DEPTH and the TARGET IDENTIFICATION of each object detected. After
a target is detected, these indicators will remain illuminated with this
information until the next target has been detected.
