ADJUSTING SENSITIVITY 31

The X-Terra 70 is highly sensitive and has a wide Sensitivity adjustment range. It is important to set the correct Sensitivity level for your detecting conditions.

Sensitivity is the detector’s level of response to a target and its environment. Real targets are indicated by distinct beeps. Interference or false targets are interpreted as crackling or popping sounds.

Tiny ferrous junk targets might be detected when the Sensitivity is set to a high level. The detector will also be affected by minerals in certain soils and signals from electrical appliances.

Some experimentation with the Sensitivity scale may be required for different areas. For beginners, start with a low setting and increase it progressively.

Decreasing the Sensitivity of the X-Terra 70 may stabilise the detector, reducing false signals and interference, and assisting in differentiating between signals caused by soil mineralisation and those of metal targets. Always choose the highest stable Sensitivity setting to ensure optimum performance.

For beach detecting, a setting below 15 may be required. In high trash areas, such as modern parks, a setting below 9 may be required, especially when searching for shallow coins.

Press MENU SELECT and choose Sensitivity.

Use the + and – buttons to adjust the Sensitivity level.

Press PINPOINT DETECT, to return to detection.
