Testing and using the
detector
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 sound 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.
