DEPTH INDICATOR
In Discrimination Mode, each time an object is detected, a Bar Graph
illuminates in addition to the Target-ID.
The Bar Graph is a graphic representation of the distance from the searchcoil,
and is calibrated to a coin-sized object.
• More bars indicate a deeper object.
• Fewer bars indicate a shallower object.
The scale for coin-sized objects, with sensitivity at maximum, is:
Display:
>15cm
Depth:
(6")*
* 3 Bars: If the object is a coin, it is more deeply buried.
...or this could be the faint signal from a large, but very deeply buried,
object.
** 1 Bar: If the object is a coin, it is shallow.
...or this could be a large object deeply buried.
