BASIC OPERATION
POWERING UP
Press the ON touch pad.
All display indicators will illuminate momentarily
The inverted-pyramid depth-selection indicator on the right of the
display will stay illuminated.
UNDERSTANDING THE DISPLAY
●
1 DEPTH SELECT
The detector default to 3/4
sensitivity, indicated by
two illuminated segments.
To change the depth range
of the detector, and thus its
sensitivity to more deeply
buried objects, use the
DEPTH SELECT touch pad.
each touch of DEPTH
SELECT toggles the detector among three different sensitivity settings.
The detector is at maximum depth capability when three depth
segments are illuminated on the right of the display.
At the maximum depth setting, the detector will detect a coin-sized
object buried approximately 6 1/2 inches beneath the surface. With
two depth segments illuminated, the detector’s depth range will be
reduced to 80%, and with one depth segment illuminated, the range
will be reduces to 65%.
A more detailed explanation of depth selection is found on page 14.

2 LOW BATTERY
The LOW BATTERY
indicator will illuminate
when the 9-volt batteries
are discharged to a level
of 6.8 volts.
Replace the batteries as
soon as possible after
receiving th e low battery
indication. The detector

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 detector will sound one of three different tones, depending on the
type of metal 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.
MEDIUM TONE
Pull-tabs, 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. Medium tone objects will illuminate the
two center target indicators.
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.
Audio Target Identification (ATI) classifies metals into four categories.
LOW TONE
Nails, Bottle Caps,
& Smaller Gold
MEDIUM TONE
Old & New Pull Tabs, Zinc
Pennies (Post 1982), Nickel,
Larger Gold Objects
HIGH TONE
Copper, Silver & Brass
Copper Pennies (Pre 1982)
