get ALL METAL mode. LCD displays ALL METAL at the left lower part
of the screen.
Press GROUND TRAC several times to allow the unit to stabilize
when first going into ALL METAL mode.
Lower the searchcoil to about one inch (2.5cm) above the ground.
Slowly sweep the searchcoil above the ground. When the unit
passes over metal object, LCD will display the depth of the object.
Also the unit emits a tone. When the unit approaches the target , it
emits a higher tone.
When searching in the ALL METAL mode, it is important that the
detector be ground balanced to offset the effects of any minerals
present in the soil or to balance the effects of saltwater when you
search near the ocean.
GROUND BALANCE—used to offset the effects of any minerals
present in the soil or to balance the effects of saltwater.
1. Begin with the GROUND BALANCE button adjusted to PRE SET
and lift the searchcoil about waist high in the air. Press GND
TRAC several times to let the unit stabilize before starting an
effective detection.
2. Lower the searchcoil to about one inch (2.5cm) above the ground.
If a tone is not being emitted, the PRE SET position is the proper
ground balance for that area. If a tone is being emitted, readjust
the GND BAL.
3. Lift the searchcoil in the air, turn the GND BAL counterclockwise
slightly. Push GND TRAC several times. Then repeat step 2. If
the unit still emits tone, repeat the procedure until the unit does
not emit tone.
Note:
1. Always be careful that there’s no metal on top of or under the
ground where you proceed ground balancing.
