SENSITIVITY

TARGET DEPTH

Sensitivity is the depth setting of the device. It is also used to eliminate the ambient

electromagnetic signals from the surrounding environment and noise signals transmitted

from ground.

NOTE: To obtain maximum depth performance, to eliminate the noise caused by

electromagnetic interference, try shifting the frequency first.

Sensitivity setting consists of 6 levels and is pre-defined for each mode. All modes start at the default

setting. They can be manually modified when necessary. Sensitivity adjustment applies to the selected

mode; the modified setting does not affect the sensitivity setting of the other modes.

Sensitivity setting is a personal preference. However, It is important to set the sensitivity to the highest

level possible where no major popping sounds are heard to avoid missing smaller and deeper targets.

For example; if the noise level is suitable for searching and is the same at level 3 and 6, then 6 should

be preferred.

You can increase and lower the setting by using the up and down buttons on the main screen. The

bar on the left indicates the level of sensitivity.

IMPORTANT! If you want to lower the sensitivity setting, pay attention to pressing the down button

one by one and not holding it down for a long time. As the down button is also the power button,

holding it down will cause the device to shut down.

The device provides an estimated target depth according to the signal strength during detection.

Depth Indicator: It shows the target's proximity to the surface in 5 levels during detection. As

the target gets closer, the levels decrease and vice versa.

Because each mode of the SIMPLEX+ has different depth, the depth indicator will display a

different depth level for the same target in different modes.

Depth detection is adjusted presuming that the target is a 2.5cm (1'') coin. Actual depth varies according

to the size of the target. For instance, the detector will indicate more depth for a target smaller than a

2.5cm (1'') coin and less depth for a larger target.
