Search Programs
Search Programs are implemented as a method for quickly changing multi-
ple options at the same time. Some of these options are also available in the
menu (ex. Discrimination), and some are not (ex. the type of audio being used).
The factory default settings for each program are intended for general use.
Adjustments made to options in the menu are saved each time the user
changes programs and each time the MX 7 is turned off. Performing a factory
reset as detailed on page 16 will return all Programs to their factory default
settings.

Features (Detailed)
Navigation
During normal searching there are two live controls that add convenience for
the two most common adjustments; Sensitivity and Threshold.
SENSITIVITY: During searching (in all search modes) pressing the + or -
buttons adjusts the sensitivity, or responsiveness, of the MX 7. If the sensitivity
is set too high, excessive noise will make it difficult to locate targets due to
the noise from either the ground or external electric interference. Too-high
sensitivity is noted by false signals. Lowering the sensitivity will improve perfor-
mance. Increase sensitivity for increased depth when the ground and external
conditions allow. Note: Few areas will allow maximum sensitivity.
THRESHOLD:
The MX 7 can be efficiently used with or without a threshold
hum. Threshold can be defined as a steady continuous background hum. In
all search modes, the up & down arrows control the Threshold. The lowest
setting of 0 is Silent Search. Use of a threshold provides more information
regarding what the metal detector sees. Rejected targets or ground
