“BOBBING” THE SEARCH COIL METHOD
This method takes a little more practice, but you may nd it slightly
more accurate with fewer false signals from ground minerals.
“PUSHBUTTON” GROUND BALANCE METHOD
This will probably be your method of choice in all but the most
difcult of ground conditions. It’s fast, easy and accurate. You can
use this method in either the Autotune or Target ID mode.
1. With your controls set as in the “Turn-On” procedure,
(GROUND control at 10), hold the search coil parallel
to and 6 to 12 inches off the ground. Press the
PINPOINT button and hold it until you’ve completed
step 2. Make sure you’re at least three feet away
from any metal objects.
2. Still pressing the PINPOINT button, lower the coil to the
ground. Starting at 10, rotate the GROUND control
clockwise until you hear an audio tone. Then back
it off to the exact point where the tone disappears.
Release the PINPOINT button and you’re ready to
search.
NOTES:
1. If you get an audio response as you rst lower the coil with the
GROUND control at 10, you’re probably over a piece of metal.
Move and try again.
2. If you get a sudden belltone not proceeded by an increasing
audio response as you lower the coil, you’re probably in some
very highly mineralized soil or sand. In this case, it’s best to use
the “Bobbing” method.
3. If you don’t get any audio response, or just a very faint one
as you rotate the GROUND control from 10 all the way to 0,
you’re probably in an area where there’s very little ground
mineralization. Just leave the GROUND control at 10 and begin
searching.
4. Recheck your ground balance occasionally and make sure you
haven’t accidentally moved the MODE switch.

TARGET IDENTIFICATION
7. Set your discrimination at an appropriate level. If
there’s very little trash in the area, set it low, say at
iron discrimination and dig every good signal. If there
is a lot of trash present and you’re mainly interested
in coins, set the discrimination level high—you may
even want to sacrice nickels and zinc pennies in
extremely trashy areas. If you’re looking for gold rings,
relics, artifacts, or small ancient coins, you’ll have to
set your discrimination level low. The best way to nd
out how low is to bury some sample targets or just dig
everything for awhile until you get a feel for which
target classications will be the most productive.
8. Look for repeatable signals and don’t waste time
on disappearing or one-way signals. If you hear a
good beep but can’t repeat it when you go back
over the target area, or if it beeps in only one sweep
direction, it’s probably a piece of trash—something
below your discrimination setting.
9. If you’re in a relatively non-trashy area, try searching
in the Autotune mode and then identify your targets
by switching to DISC = 0. You’ll nd more and deeper
targets this way.
10. If you’re having any difculty pinpointing or identifying
a target in the ID mode, don’t waste any more time.
Push the pinpoint button for quick pinpointing then
release it for accurate ID.
11. If your target disappears when you go into the Pinpoint
mode, you’ve probably tuned it out by pressing the
button too close to the target or over another piece
of metal. Try again, this time pushing the PINPOINT
button over another piece of ground.
12. Don’t waste a lot of time digging holes for targets
you can’t nd if your hole keeps getting deeper and
wider, cover it up and go on. You may be over a
buried pipe or some other large deep target.
