rejection sound to the point you can recognize it when compared
to the sound of a good target. Accuracy is greatly increased
sweeping the center of the target. Pinpoint (press √/X and "x"
the area, return to Discrimination (press √/X again), then pass
the search coil over target center and note the sound and display
indication.
When a metal target doesn't indicate as expected, peculiarities
within that metal's alloy mix (metal types) are usually to blame.
As alloyed steel bottle caps age, the iron deteriorates and the
better (non-iron) alloys remain and become prominent (e.g., very
old bottle caps are likely to indicate as quarters). The longer they
are in the ground, the more the iron dissolves and the stronger/
better the non-iron looks to a metal detector. Soil conditions,
corrosion factors, depth, and other variables can skew the audio
and display indications and, thus, Discrimination settings. Used
properly, however, Discrimination will more than double your time
spent digging valued targets. The point is to reject the most com-
mon trash and accept the most common good targets. The MX
Sport has 20 rejection ranges. Discrimination comes already set
up for the Program you have selected.
To Customize Discrimination:
It is sometimes necessary to customize discrimination for tar-
gets you want to accept/reject. Iron will likely jump all over the
scale inconsistently. You can only reject the first range for iron.
For other targets that indicate consistently in a range, identify
and then reject that range.
1. Press Options and use up & down arrows to select Discrimi-
nation.
2. Use the + or - buttons to select the desired range you want
to change, indicated by the flashing curser. Press pinpoint
button to toggle between accepting or rejecting that range.
The pinpoint button changes that range from reject (solid
indicator bar) to accept (blank indicator bar) or from accept
(blank indicator bar) to reject (solid indicator bar).
3. Press Options to exit, or wait 10–15 seconds for the Options
mode to automatically time out.
