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 three different tones. These three tones correspond to the three target categories depicted on the LCD display.
LOW TONE
Ferrous objects, such as iron and steel, will induce a low tone. Small gold objects can also induce a low tone.
MEDIUM TONE
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.
