Assemble your detector as per instructions from your operations manual making sure that
there is enough slack in the cable where the coil meets the lower stem to allow for flip-
flopping at different angles. Place your detector lengthwise on a table with the coil hanging
over the edge. Now position the coil so that it faces upwards towards the ceiling as
illustrated. To eliminate any possible false signaling make sure that there are no electronic
devices turned on nearby such as TV's and Radios.
Air Testing in the "DISC" mode:
Turn your unit on as per the instructions in your Operations Manual. We will start by testing
the unit in the "DISC" mode.
Quick Draw, Sharp Shooter _ Press the DISC touchpad on top of the control box. The
mode indicator will now have an arrow at "DISC".
Big Bud Select 220-D _ Make sure the toggle switch is in the "DISC" left position-Also, be
careful that the Blanker toggle switch on the right side of the control box is in the middle
position; otherwise, you will not be able to air test anything less than 2-4 inches from the
coil.
Other Bounty Hunters _ The same instructions under the Select 220-D applies. If your
Bounty Hunter has a Blanker, be careful that it is turned off-follow your operations manual to
determine if your blanker is set in the off position.
Other required settings applied to all models: Make sure that your Disc/Notch control is
turned completely counterclockwise. Turn your Sensitivity 3/4's or more. If turned too high,
you may get chattering and false signals.
In the "DISC" mode, all items to be tested will require movement. When operating in the
field, this would mean slowly sweeping the coil over the target. When air testing, you will be
required to sweep the target slowly over the coil. When sweeping coins or rings, be aware
that the targeted area will be much more receptive if the coin or ring is swept flat instead of
at an angle. Most coins and rings fall flat on the ground and usually do not end up being dug
at angles; even though, there are rare cases where a coin can be dug up on its edge. Be
careful not to sweep the target too close to the coil or a double-signal may be emitted-three
inches from the surface of the coil should suffice for this air test. Remove all jewelry,
bracelets, and watches from your hands or wrist before attempting to air test.
Let's start by slowly sweeping your sample nickel across the coil. Notice that the detector
emits a low tone and indicates "Nickel" on the readout. Observe your meter/readout
carefully making sure that you're getting a good ID indication. Sometimes there will be slight
variation and the ID indicator may jump back and forth and your tones may vary; for
instance, one time you sweep the nickel it may read pull-tab-another time, it may read
nickel. To minimize this from occurring, try lowering the coin closer to the coil. Experiment
with turning down the Sensitivity; sometimes, if the Sensitivity is set too high, false signaling
will occur. Be careful not to sweep the coin too quickly over the coil; this also applies when
sweeping your coil in the field.
Our next test involves the ominous pull-tab. Try sweeping the pull-tab slowly across the
coil being careful to follow the same procedure used for the nickel air test. Notice the
different tone being emitted by the pull-tab from the nickel-a medium tone.
