Using Pinpoint; Reading The Display - Fisher GOLD BUG Owner's Manual

OPERATING IN DISCRIMINATION MODE
Press-and-Hold the Pinpoint button to narrow down the location of a buried metal object.

Using PINPOINT

Pinpoint is a mode of detection which does not require the searchcoil to be in motion.
A motionless searchcoil held over a metal object will induce a hum; volume and
pitch of the hum increase with target strength.
The approximate target depth, in inches, will be indicated in the center of the screen.
The depth scale is calibrated to coin-sized objects.
relative depth is indicated for larger or smaller objects.
Upon releasing the button, you will return to the motion Discrimination detection mode.
If you keep the Pinpoint button depressed for a long time, the audio tone may begin to drift.
If you plan to search like this, release and re-press the button periodically to avoid
drift. Drift may result in a loudening sound or a reduced sensitivity with no sound.
See the manual section on Target Pinpointing for how to narrow down a target's location.
This technique is indispensable as long-buried metals can look exactly like the
surrounding soil to the naked eye. If you are not adept at pinpointing, digging up a
small metal object can be very frustrating. So learn how to narrow-it-down.
RE DING THE DISPL Y
each time you pass the searchcoil over a metal object, a 2-digit value will appear in
T RGET-ID
the center of the display. See the manual section on Target Identification for a better
understand of these values.
Three segments will simultaneously appear above the arc at the top of the screen.
This represents the same Target Identification, but displayed graphically within the scale.
This display works as in the All Metal Mode.
T RGET SC LE
The arc across the top classifies metal objects.
each time a target is detected three segments will illuminate above the arc.
The segments will remain illuminated for three seconds.
This indication shows the approximate classification of the buried metal object.
See the section on Target Display for a more detailed explanation.
Iron is on the left. U.S. dimes and quarters are to the far right.
In an air test, gold indicates right of center -- the larger the gold piece, the
farther to the right.
In the ground, the ID of gold may jump around with each pass of the coil.
each time a target is detected, bars will illuminate on the bottom left showing the
SIGN L
strength of the target's signal.
If all 7 bars illuminate, the target signal is strong.
This may be a large metal object.
Or it may be a coin-sized metal object close to the surface.
If only a few bars illuminate, the target signal is weak.
This may be a deeply buried object, even a big one.
Or it may be a very, very small metal object, close to the surface.
The depth of a coin-sized object can be confirmed using Pinpoint.
