mode. All METAL also comes with auto ground balance. It’s used to
find not only ferrous metal, but also non-ferrous one (see more details
below).
b. VOLUME—Rotate the control clockwise to power on the unit. Rotate
it fully counter clockwise to power off the unit.

TESTING AND USING THE DECTECTOR
The metal detector has two operation modes: ALL METAL & DISC. All metal is
used to find all kinds of metal targets. DISC is used to discriminate the metal
type.
In general case, user firstly sets the operation mode to ALL METAL, DISC to
counter clockwise end, SENS to high position. Then hold the search coil parallel
with the ground about 1~5cm above the surface. Sweep the search coil from
side to side in an arc line of 7cm motion.
When the detector detects a buried target, it sounds a tone. User can make a
visual note of exact spot on the ground where the detector beeps.
Then stop the search coil directly over this point on the ground. Move the
search coil straight forward away from you and straight back towards you a
couple of times. Meantime slowly rotate the DISC control clockwise away from
ALL METAL until the unit does not sound or sounds short tone. You can identify
what kind of metal is rejected according to the setting position of DISC.
