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
MEDIUM TONE
Newer pennies
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 | MEDIUM TONE | HIGH TONE |
