9.6 Surface Elimination
The surface elimination mode only works in motion mode and can improve the detection accuracy in soils
with lots of trash. It restrains the signal from trash in the soil.
Note that the detector's sensitivity is decreased in this mode.
Press the SURF ELIM button to enter or to quit the surface elimination mode.

Using Headphones

Using headphones (not included) makes it easier to identify subtle changes in the threshold level. It also
reduces battery drain.
To protect your hearing, set the volume level to the lowest setting, plug in the headphones and
gradually increase the volume level.
Extended exposition to high volume levels can lead to permanent hearing loss.
9.8 Audio Target Identification (ATI)
You do not always keep your eyes on the LCD display when hunting in the field. However, the LCD
display is very accurate in identifying buried objects.
Therefore, this metal detector features an audio feedback system to alert to the nature of the target. The
three-tone system only functions in motion mode (DISC, NOTCH and AUTO-NOTCH mode).

In-the-Field Technique

10.1 Reading the Display

Target Indicator
The LCD display shows the probable targeted metal, as well as the probable depth of the target. The
metal detector will register a repeating, unchanging sound when a buried target has been located and
identified. If, upon repeated passes over the same spot, the target identification reads inconsistently, the
trash is probably trash or oxidized metal. With practice, you will learn to unearth only target generating
repeated signals. Also, the greater the distance between the target and the coil, the less accurate the
target identification.
