IN THE FIELD TECHNIQUES
- No-motion modes
In the No-Motion All-Metal Mode, coil sweep technique is not important. Rather,
user retuning is critical.
The detector does not automatically adjust to changing ground and
environmental conditions; the operator is required to make the adjustment. If
the detector sounds a constant tone over all areas of the ground, retune the
detector by pressing the GroundTrac button.
RETUNING
Keep the coil still, just above the ground surface, and press the GroundTrac button.
Make sure that the spot on the ground you chose for tuning did not contain
metal; pass over the area with the coil again to insure that the detector does
not emit a tone.
TEMPERATURE CHANGE
If the detector moves from one temperature environment to another, or if the
temperature changes, you must retune the detector until the temperature
stabilizes. If you move from a cooler to a warmer environment, the detector may
emit a constant tone; if so, retune. If you move from a warmer to cooler
environment, the detector may lose sensitivity; if so, retune.
PINPOINTING
How To Pinpoint Targets Using The ALL-METAL Mode
When you’ve discovered a target you wish to dig, do the following:
1.
Hold the searchcoil about half an inch above the ground, off to the side of
where you think the target probably is.
2.
Tap the ALL METAL touchpad button. This will put you into the All Metal
Pinpoint mode. NOTE: unlike the other modes, this mode does not require
the searchcoil to be in motion to detect a target.
3.
Lift the searchcoil slightly, and pass it over the target. The sound will be
loudest over the center of the target.
To Narrow It Down Further:
4.
Now that you know about where the target is, again lower the searchcoil to
about half an inch above the ground, near the center of the target but not
right over the top. Tap the button again. The sound will instantly go away.
5.
Lift the searchcoil slightly and move it horizontally over the target. The audi-
ble response zone will be much narrower. If you move the searchcoil
around right and left and also forward and back, making an “X” pattern over
the target, you can determine the location of the target usually within an inch
or two.
NOTE:
if at any time it seems like the signal may be drifting, just tap the
Ground-Trac button. This restores the signal to its zero level.
