c) Testing and using the detector
To learn how the detector reacts to different metals, you should test it before you use it the first time. You can test
the detector indoors and outdoors.
- INDOOR testing and use
NOTE: Never test the detector on a floor inside a building. Most buildings have metal of some kind in the floor,
which might interfere with the objects you're testing, or mask the signal completely.
1. Slide the POWER switch to ON.
2. Select the operating mode.
3. Place the detector on a wooden or plastic table, and remove any watches, rings or metal jewellery you are
wearing.
4. Adjust the search coil so the flat part points towards the ceiling.
5. Slowly sweep a sample of the material you want the detector to find (such as a gold ring or a coin) 2-3
inches above the face of the search coil. When the detector detects any metal within the selected range, it
sounds a tone and an arrow appears below the target icon. The LCD displays the depth of the target.
NOTE: if you are using a coin, the detector will detect it more easily if you hold it so that a flat side is
parallel with the flat side of the search coil. A sweep with the side of the coin over the search coil might
cause false indication and unstable display of the arrow.
- OUTDOOR testing and use
1. Slide the POWER switch to ON.
2. Select the operating mode.
3. Find an area on the ground outside where there is no metal.
4. Place the material you want the detector to find (such as a gold ring or a coin) on the ground.
NOTE: If you are using a valuable metal sample such as gold to test the detector, mark the area where you
placed the item, to help you retrieve it later. Do not place it in tall grass or weeds.
5. Hold the search coil level to the ground about 1-2 inches above the surface, slowly move the search coil
over the area where you placed the sample, sweeping the search coil in a side-to-side motion.
6. If the detector detects the item, it sounds a tone, and an arrow and the depth appear on the display below
the target icon.
7. If the detector does not detect the item, make sure that the target mode is set correctly for the type of metal
you're searching for. Also make sure that you're moving the search coil correctly.
d) Search coil sweeping hints
- Never sweep the search coil as if it were a pendulum. Raising the search coil while sweeping or at the end of a
sweep will cause false readings.
- Sweep slowly. Hurrying will cause you to miss targets.
- It's better you sweep the search coil from side to side in a straight line and keep the search coil parallel with the
ground.
- The detector responds with a signal when it detects most valuable metal objects. If a signal does not repeat after
you've swept the search coil over the target a few times, the target is probably junk metal.
- False signals can be caused by trashy ground, electrical interference, or large irregular pieces of junk metal.
- False signals are usually broken or non-repeatable.
e) Adjusting sensitivity
After you've become familiar with how your detector works, it's important to fine tune the sensitivity to get a good
result. Press the touch button SENS on the panel. Then press Up or Dn to increase or decrease the sensitivity.
The level on the segment will be displayed form high to low position.
NOTE: in order to detect a target deeply buried, you can adjust the SENS to a high position. But don't set the
SENS lever to MAX, because the detector will receive interference and false signal from broadcast antennae and
other electronic lines. The detector will have unstable arrow and irregular tone indications.
