XP Metal Detectors Deus V4, User Manual

Page: 10 / 52

Discrimination enables undesirable targets to be rejected by raising or
lowering a threshold below which certain metals are differentiated.
The conductivity scale (0 to 99) for metal targets shown below will help
you better understand the discrimination range and its limits, and see
how it corresponds to the
digital display of target conductivity on the
remote control main menu.

Increasing the discrimination value enables you to gradually reject any target whose conductivity is
lower than the setting. For example, if you tune the discrimination level to 10, you will reject iron with
a value of between 0 and 10. If you tune it to 40 you will also eliminate small pieces of aluminium
foil whose conductivity is less than 40.If you wish to reject other rubbish with higher conductivity, such
as pull tabs from aluminium drinks cans, lead shot or copper hunting cartridges (whose conductivity is
60-75), you must also be prepared to accept the elimination of certain good metals with similar conduc-
tivity.If you are particularly bothered by contamination registering as highly conductive on the digital
screen, and you still wish to reject it, it is betterto do so using the NOTCH rejection setting.
Two alternatives involve selecting a low level of discrimination, between 5 and 10, then using either:
- 1/ The digital target display to more or less visually discriminate a target category.
- 2/ The Multi-tone mode to discriminate undesirable targets using a selected audio tone.
In both cases the decision then lies with you on whether or not to dig.

Depending on the frequency setting used, a target’s conductivity
is perceived differently by the detector. The digital conductivity display
may therefore vary depending on the frequency.
The 0 to 10 range relates to the rejection of iron. To achieve greater
precision in this range there is a digit after the decimal point (from -6.4 to 9.9).
In several menus, particularly at the top left of the Discrimination
screen, a reminder of the target conductivity index is displayed, which helps
you when adjusting the discrimination level.
