Lobo SuperTraq Operator Instruction Manual
There are 2 parts in Step 5:
Identify the Target Response
Use Discrimination
Flip the MODE switch to DISC
Leave the DISC LEVEL control set to min
Note: In Discriminate Mode, you will not hear the continuous threshold sound of the All Metal Mode.
Identify the Target Response
Hold the quarter in your hand and move the quarter back and forth about 12 inches in front of the
searchcoil bottom.
Gradually move the quarter closer to the searchcoil—as you continue to move it back and forth—until
you hear a "beep." This beep is 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 coin still then moving it
slightly. 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. Your detector can respond to objects made of any kind of metal if there is movement
between the object and the detector. A detector operating in this way is called "Silent Search."
Use Discrimination
Turn the DISC LEVEL control from min to max
Pass the quarter back and forth in front of—and close to—the searchcoil bottom. Notice the sound as the
coin nears the center of the searchcoil. Now, try this with the nickel and then the zinc penny. Notice there
is no sound with these two coins. The ability of a metal detector to ignore certain types of metal is called
"discrimination." A detector operated in this way is referred to as "Silent Search Discriminate Mode."
Control settings to ignore most zinc and nickel objects can be:
MODE switch: DISC
DISC LEVEL: max
Move the DISC LEVEL control from max to 7
Pass each of the three coins in front of the coil. Notice the quarter and the zinc penny now cause a target
response sound.
Control settings to ignore most nickel objects can be:
MODE switch: DISC
DISC LEVEL: 7
Now move the DISC LEVEL control from 7 to 4
Pass each of the three coins in front of the searchcoil. Notice all three coins now cause a target response
sound.
Control settings to include newer US coins while excluding most iron objects can be:
Mode Switch DISC
DISC LEVEL 4
8 sur 18
