Adjust Ground
This is a critical step for accurate operations. Adjusting the ground settings will allow
separation from false signals given off in highly mineralized soil conditions.
•
With Mode set to VLF, lower the search coil to 0.5 inch to 0.6 inch (1.3 to 1.5 cm) above
the ground.
•
If the analog needle swings to the right (Non-Ferrous), adjust Ground setting to Normal.
If the analog needle swings to the left (Ferrous), adjust Ground setting to Basalt.

Adjust Discrimination
IMPORTANT! Re-adjust discrimination settings for each new search location. Discrimination
settings determine whether the detector will distinguish between different types of ferrous and non-
ferrous metals.
a.
With Mode set to VLF, lower the search coil to 0.5 to 0.6 in. (1.3 to 1.5 cm) above
the ground.
b.
The higher you set the discrimination, the more sensitive your detector becomes to
the differences between large aluminum and gold pieces. However, it also becomes
less sensitive to small finds, like coins. If you set your Mode to TR2, begin with
discrimination set to midrange and adjust to the best position for the site.

Adjust Sensitivity
To adjust the search coil's ability to detect objects at different depths in the soil, rotate
sensitivity between Minimum and Maximum. For maximum detection depth, leave sensitivity
setting as high as possible. If the detector makes a chattering noise, reduce sensitivity until
chatter stops.
No detector is 100 % accurate. Various conditions influence metal detection. The detector's
reaction depends on a number of factors:
•
The angle at which the object rests in the ground
•
The depth of the object
•
The amount of iron in the object
•
The size of the object.
•
If buried trash is so heavy in an area, you get false signals, slow your sweep speed and
use shorter sweeps.
•
Recently buried coins might not respond the same as coins buried for long periods of
time due to oxidation.
•
Nails, nuts, bolts and other iron objects tend to oxidize and create a halo effect. This
effect is where, due to natural elements of the soil and oxidation of metals, target
signals might not be in a specific position. This makes these objects very hard to
locate accurately.
