Display & Controls
POWER
A quick press of the button turns the MX Sport ON. Another
quick press of the power button toggles the backlight on and off.
Pressing and holding ON/OFF for a second turns the MX Sport
OFF.
Options: Activates option selections. Up & down arrows select
among available options. Pressing + or - adjusts that specific op-
tion. Select another option by pressing again or exit by waiting for
the option to time out automatically (10–15 seconds).
√/X: Access Pinpoint mode. Also used for some menu sequenc-
es.
In Search mode, + and - adjust Sensitivity; in Options they select
the level of adjustment.
TRACK
The MX Sport automatically self-adjusts to the ground mineraliza-
tion currently being searched and tracks to changes in miner-
alization. Ground compensation and tracking to ground mineral
changes is fully automatic. Automatic ground tracking improves
performance over typical/normal ground where ground mineral
changes are naturally occurring and gradual.
Spotty high ground minerals (naturally occurring or not), mixed
with lower mineralization, can cause errors in ground tracking
and result in instability and difficulties (as if the sensitivity was set
too high for the area). If stability does not return at reasonably
reduced sensitivity settings, spotty high mineralization is likely the
cause. To search these difficult areas, locking the ground balance
at a fixed level more often than not resolves or reduces instability.
Pressing the TRACK button can lock tracking. However, the level
the ground balance is set to when locked is critical for stable op-
eration. Holding the Track button puts the detector into Ground
Grab mode, where the number displayed is the relative ground
phase, and the depth meter shows ground strength.

• Option #1: In 80% of situations, tracking can be loced as
soon as the detector is turned on. This will result in improved
performance in difficult spotty areas. Locking the Tracking
prior to searching locks the ground balance at the ferrite
(high iron) level.
• Option #2: In 20% of situations, a natural or man-made spot-
ty mineralization may still cause difficulties at the initial fer-
rite, locked-ground rejection level. In these areas, find a highly
mineralized spot that is representative of all the spots in the
area, sweep the search coil 6–12 times (or until it doesn't
respond) and press the TRACK button. In this case, the user
is locking the ground rejection level at the high mineral spot
so that all similar spots can be ignored (no response).
If the minerals within these spots exceeds typical ground mineral
levels, and are seen as metal ore, they can not be reduced by
ground tracking. Reducing the sensitivity of the detector, or using
the discrimination mask, is necessary to reduce metal respons-
es. In some regions, hot rocks (iron rich stones) can exceed the
metal content of a mineral and thus exceed the range of any
metal detector's ground rejection. Any metal (gold silver, copper,
nickel, aluminum etc) can be found in metal ore (rock) form, as
well. Again, Discrimination and Sensitivity adjustments are the
only way to deal with these responses.
The MX Sport captures ground mineral information in real time.
Turning off the Power and turning back on will automatically un-
lock a locked ground balance level. This is necessary to capture
new ground information. Switching in and out of the Beach mode
(a different ground rejection range) will also unlock a locked
ground balance. When powering ON/OFF or switching in or out
of the Beach mode, remember to re-lock the ground tracking if
that is required for the area.
SENSITIVITY
Used to increase or decrease responsiveness to targets, ground,
and external electrical noise. Maximum depth will be achieved by
using the highest setting possible for the area. Settings 1–10
are available. Increasing sensitivity to 10 activates the Audio
