BASIC OPERATION
4) Press ZAP. An "R" appears under the segment to be eliminated.
5) Pass the searchcoil over the same object again.
The undesirable object is eliminated from detection
The ZAP control is easy to use in the field. As you are detecting, and
encounter an object which you wish to eliminate from detection, simply
press the ZAP touch pad after detecting the object.
The ZAP control eliminates the most-recently detected object category from
detection. The category eliminated is indicated with an "R".
PIN POINT MODE
Since long-buried objects can appear exactly like the surrounding soil, the
process of finding the exact location of a small object, such as a coin, can be
time-consuming and frustrating. Objects buried many inches deep present
an especially daunting challenge. In addition, during the unearthing process,
care must be taken not to damage valuable relics. The best solution to these
problems is the no-motion PINPOINT mode.
At any time during operation, press the PINPOINT touch pad, and the detector
enters the no-motion mode. In the PINPOINT mode, any object in the coil's
detection field will induce a monotone hum. The location of a coin-sized object
can be discerned with pinpoint accuracy as it will induce a tone only when it
falls within the inner circle of the searchcoil. Pass the coil slowly over and
around the target zone, and you will quickly see the target's exact location.
Be sure that the detector is properly GROUND BALANCED before using the
PINPOINT MODE. See page 20 for manual ground balancing instructions.
Also, consult page 22 for proper no-motion field techniques.
The Target Identification and Target
Depth indicators are disabled in this
mode.
To discern the identification
and depth of an object, you must use
one of the motion modes of operation.
HEADPHONE JACK
Using headphones (not supplied)
improves battery life, and prevents the
sounds from annoying bystanders.
It also allows you to hear subtle
changes in the sound more clearly,
particularly if searching in a noisy
location. For safety reasons, do not use
headphones near traffic or where other
dangers are present. This device is to
be
used
with
interconnecting
cables/headphone cables shorter than
three meters.

AUDIO TARGET IDENTIFICATION
While the LCD (Liquid Crystal Display) is very accurate in identifying
buried objects, the user in the field does not always maintain the display
screen in his field of vision. Therefore, we have incorporated an audio
feedback mechanism to alert the user to the nature of buried objects.
This audio feedback system first alerts the user to the presence and
classification of objects, whose nature and location can be confirmed
using the LCD display.
The 4-tone audio target identification system functions only in the motion
modes of operation. The detector must be in the DISCRIMINATION,
NOTCH or ALL-METAL modes, as indicated on the display. In PINPOINT
mode, the detector will emit only a monotone sound.
The detector can sound four different tones, depending on the object detected.
BASS TONE
Ferrous objects, such as iron and steel, will induce a bass tone.
The smallest gold objects can also induce a bass tone.
LOW TONE
Pull-Tabs, nickels & smaller gold
MEDIUM TONE
Newer pennies (post-1982), larger gold objects, zinc, small brass
objects, and most bottle screw caps will induce medium tones.
Many recent vintage foreign currencies will induce medium tones.
HIGH TONE
Silver and copper coins, larger brass objects, older pennies (pre-
1982), and highly oxidized metals will induce high tones. Quarters,
dimes and other precious coins fall into this category.
BASS TONE
LOW TONE
Nails, Iron Objects,
Pull Tabs, Nickels,
& Smallest Gold Objects
& Smaller Gold
Audio Target Identification (ATI) classifies metals into four categories.
(motion modes only)
MEDIUM TONE
HIGH TONE
Zinc Pennies (Post
Copper, Silver & Brass
1982), Larger Gold
Copper Pennies (Pre
Objects, Many screw
caps
1982)
