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.
Correct
Wrong
- Sweep slowly. Hurrying will cause you miss targets.
- It is better you sweep the search coil from side to side in an arc line of 3 inches
motion and keep the search coil parallel with the ground.
If the detector detects the target, it sounds a tone and the cursor above the target ID
will light. Also, LCD displays the numeric range of target as well as the depth (signal
strength).
If the detector does not detect the target, make sure that the mode is set correctly
for the type of metal you are searching for. Also make sure that you are moving the
search coil correctly.
Note:
- The detector responds with a signal when detects most valuable metal objects. If
a signal does not repeat after you sweep 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 piece of junk metal.
- False signals are usually broken or non-repeatable.
Adjusting SENSITIVITY
After you become familiar with how your detector works, it is important to adjust the
sensitivity to get a good effect. Press the SENS button on the panel and press + or –
to increase or decrease the level of sensitivity. The level will be displayed on
the LCD.
Note:
In order to detect the target deeply buried, you can adjust the SENS to a high
position. However, don’t set the level of SENS to Max position. Otherwise, the
detector will receive interference and false signal from broadcast antenna and other
electronic wires. The detector will have unstable and irregular indications.
Using LIGHT
In dark area, you can use LIGHT for better searching. Press MENU to select LIGHT.
Then, press + or – to adjust the level (0-9) of LIGHT. The level will be displayed on
the LCD.
Note: As the light consumes more power, we suggest you setting the value to 0 in
normal environment.
FACTORS THAT AFFECT THE DETECTING
It’s difcult to have an accurate detecting result. Sometimes, the detecting may be
restricted by some factors:
- The angle of the target buried in the soil
- The depth of the target
- The level of oxidization of the target
- The size of the target
- Electro-magnetic and electrical interference surrounding the target.
In area of highly mineralized ground or wet sand, the detector will sound even if there
is no metal. In this case, you can lower the sensitivity or increase the DISC numeric
value. At the meantime, enhance the distance between the search coil and the
ground.
In area with trashy metal, you can set DISC numeric value to 50. In this case most
nails and small pieces of iron will be eliminated.
Metallic digging tools will also affect the detection if they are near the search coil. So
it’s better to place them a little bit far away.
