ADJUSTING THE POLE & SEARCHCOIL
The pole length should be adjusted so that the detector does not become uncomfortable or tiring after
long periods of use. The detector grip should rest in your hand with your arm relaxed, your elbow straight but
not locked, with the pole extending out in front of you at the approximate angle shown in the photo.
You should be able to swing the detector back and forth in front of you —using relaxed shoulder
movement—while keeping the searchcoil as close to the ground as possible. This swinging movement is often
called a "sweep."
The searchcoil should not touch the ground during your sweep. The pole length should be adjusted to
allow this without having to lift the detector with your elbow or shoulder. The searchcoil should rest about one
inch above the ground while you are standing erect. The angle of the searchcoil should allow the bottom to
be parallel to the ground.
The pole length is adjusted by depressing the spring buttons and extending or shortening the pole until
the spring buttons click into the set of holes that give you the most comfortable pole length.
To adjust the searchcoil angle, simply loosen the searchcoil thumb nut slightly and move the searchcoil
into the desired position. Tighten the searchcoil thumb nut by hand so that the searchcoil will hold in place.
QUICKSTART SELF GUIDED TUTORIAL
The QuickStart is designed to help you use your new µMAX Bandido metal detector right away, even if
you have never used a metal detector before. Just follow each easy step carefully and you'll quickly see how the basic detector functions work.
You'll also be introduced to some important concepts on the way.
Here's what you will need:
1.
Your fully assembled µMAX Bandido metal detector
2.
Three newer coins: a penny*, a nickel and a quarter
3.
A nonmetal table or counter surface
4.
Approximately 20 minutes to complete the QuickStart
*must be 1984 or newer made of zinc
Here's what you will do:
1.
Perform an Audio Battery Test
2.
Adjust the SENSITIVITY control
3.
Perform an air test in All Metal Mode
4.
Perform an air test in Discriminate Mode
Prepare for the Quickstart
Place your assembled µMAX Bandido on the nonmetal surface. Make sure there are no metal objects near the coil. Remove any jewelry from
your hands and wrists.
Start with these control settings:
DISC LEVEL control set to MIN
l
SENSITIVTY control set to POW OFF
l
TUNE switch set to NORM
l
MODE swith set to DISC
l
GROUND control set to the middle of its range:
l
turn it 5 complete turns counterclockwise then,
turn it 2 complete turns clockwise and stop.
The GROUND control should be left at this setting for the entire QuickStart.
Step 1 Perform an Audio Battery Test
Turn the SENSIIVITY control from POW OFF to 1
l
You will hear the battery test tone for a few seconds as the battery is automatically tested. When the tone stops the detector is on the controls
are ready for adjusting.
Function Demonstrated: How the battery test tone will tell you the battery is working each time the detector is turned on.
NOTE: You should always perform the Audio Battery Test with Mode Switch set to DISC.
Step 2 Adjust the SENSITIVITY control
Turn the SENSITIVITY control from 1 to 8
n
This is a good setting to begin with each time you use your detector. Leave the control at this setting for the rest of the QuickStart.
Function Demonstrated: Where to set the SENSITIVITY control for basic operation.
Step 3 Perform an air test in All Metal Mode
Identify the Threshold Sound
Identify Target Response
Retune the Threshold
Flip the MODE switch to ALL METAL
l
Listen to the continuous, fairly even tone. This is called the "threshold sound". You will hear the threshold sound only when operating the
detector in All Metal Mode.
Hold the quarter in your fingertips and move the quarter from side to side about 12 inches from the front of the searchcoil.
Gradually move the quarter closer to the searchcoil as you continue to move it from side to side until you hear the threshold sound
increase. This increase in volume is called the "target response sound".
Continue to move the coin to test the target response sound. As you do this, try varying the distance or angle of the coin. Try varying the
speed you move the coin. Try holding the cold still and then moving it slightly. Try passing it in front of the edge of the searchcoil and then under
the center. Notice the differences in the target response sound with each change.
Repeat the test with each coin. Notice that the detector responds to each coin although the target response sound may vary, sometimes subtly.
Your detector will respond to objects made of any kind of metal when the object is in the searchcoil's sensitivity area or "range". Operating your
detector in this way is called a "no motion All Metal Mode with Normal Tune".
Retuning the threshold
Hold the quarter still about 2 to 4 inches from the searchcoil, in line with the searchcoil center. Listen to the target response sound for 1 or 2
seconds. Do not move the quarter!
Flip the MODE switch to RETUNE and release it
l
Notice that the target response sound will decrease to the regular level of the threshold sound. Now, slowly move the quarter from side to side,
going past the edge of the searchcoil. Notice the regular threshold sound is gone and the target response sound is now a "beep" that occurs when
the target passes in front of the searchcoil center. This technique is used to "pinpoint" the exact location of an object.
