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 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.

Pull Tabs, Nickels,
