B. The SENSITIVITY control can be varied from a setting of 1 to
a maximum of 10 with the arrow buttons when the SENS icon is
flashing. As with most detectors, set the sensitivity higher for best
depth performance in soils that are low in mineralization. As the
mineralization gets worse, lower the sensitivity setting as needed.
Please note that a SENS setting of 1 will still yield excellent results.
Remember, to exit the MENU mode at any time, simply press &
