How to Use the Detector

a. Keep the detector in the search position and lightly press the coil onto the ground until it is parallel to the ground surface. The coil should maintain this parallel position, approximately 2-5 centimeters above the ground when you raise it to the correct swinging height.

b. Always swing the coil back and forth closely and parallel to the ground. Avoid sliding the coil along the ground if possible. Excessive shaking and bouncing can result in false signals, inaccurate target identification, and significant wear.

c. Overlap your search strips and practice swinging the coil in a side-to-side manner while taking a small step forward at the end of each strip. Ensure that each swing slightly overlaps the previous one to cover the entire ground area. Throughout the entire process from left to right and right to left, the average swing time should be around 2-3 seconds. Avoid swinging the coil too fast, or you might miss objects.


Missed Targets/No Metal Detection

a. The target area may be filtered out. Set the detector to Full Metal mode. The DISC mode may reject certain types of metal, making them undetectable.

b. The search coil is not parallel to the ground.

c. Moving too quickly will result in missed targets (!).

d. The sensitivity is set too low.

e. Low battery power.

f. Loose cable connections.

g. This product is a motion metal detector. You need to detect metal objects by moving the search coil slowly.

h. High humidity.

Unexpected Beeping or Inaccurate Test Results

a. Sensitivity is set too high.

b. Environmental electromagnetic interference, such as power lines, appliances, smartphones, and mobile phone towers. Be aware of electromagnetic fields and interference from other metallic objects, such as household appliances and rebars, when searching indoors. If searching outdoors, be mindful of possible interference from underground water pipes and electrical lines.

c. Incorrect movement of the coil can result in false signals (moving too fast or not parallel to the ground) and may cause missed targets.

d. Nearby metal detectors may be particularly susceptible to interference.

e. Saline-alkaline soil or heavily mineralized soil.

f. The search coil cable is not properly wound around the shaft.

g. Low battery power can lead to inaccurate test results.

h. Small or deep targets. To detect targets at greater depths, increase the sensitivity of the product.

i. Large targets. Maintain a distance of 2-5 cm between the coil and the target.
