Walk slowly forward. Sweep the coil from side to side in a wide, overlapping arc. Pinpointing a Target
| Problem | Possible Cause | Solution | | :--- | :--- | :--- | | | Dead or improperly installed batteries | Check the battery orientation. Replace the 9V batteries. | | Erratic beeping / false signals | High ground mineralization | Press the RESET button while holding the coil stationary in the air. If that doesn't work, lower the SENSITIVITY knob slightly. | | Low volume or weak detection | Low battery power or poor connection | Run the battery test. If the needle is low, replace the batteries. Check the coil connection cable for damage. | | Detector doesn't respond to metal | Sensitivity set too low or Discrimination set too high | Increase the SENSITIVITY knob. Turn the DISC knob to "0" to ensure you haven't rejected all metal types. Press RESET . | | Metallic taste or vibration in the shaft | Static buildup or loose coil cable | Unplug and re-plug the coil cable from the control box, ensuring the connection is tight and the signal wire is securely wrapped around the stem. | Orbitor Prospector 100 Metal Detector Manual
Filters out unwanted items like pull-tabs or iron nails. Walk slowly forward
With basic care, your detector will last for years. Always remove the batteries if storing the unit for more than a month to prevent chemical leaks. Clean the search coil with a damp cloth after use, but never submerge the control box in water—only the coil is waterproof. Troubleshooting Common Issues Replace the 9V batteries
Do not lift the coil at the end of your swings like a pendulum; lifting causes the detector to lose depth and give false readings.
To prevent false signals from mineralized soil, follow this calibration process before searching: : Turn the Test/Operate dial to Operate .
Keep the search coil parallel to the ground surface at all times. Avoid lifting the coil at the end of each swing like a pendulum. Sweep slowly from side to side, overlapping each stroke by 50 percent.
