TESTING AND USING THE DECTECTOR
This 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.
Set 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 .5~2 inches / 1~5cm above the surface. Sweep the search coil
from side to side in an arc line of 2.75 inches / 7cm motion.
When the detector detects a buried target, it sounds a tone. 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 detected according to the setting position of
DISC.
A reference for you to know what kind of metal is rejected depending on
the DISC setting.
