Quest Metal Detectors Troubleshooting Guides

All Quest Metal Detectors

• Recharge the detector.

Quest Q60 Metal Detector

• If the detector shows no conductance number in the middle, the coil might not be connected to the control unit. Check the cable between the coil and the control unit.
• If it just doesn‘t make a sound, check if the volume is set to zero or the wireless headphones-mode is activated.

• Perform an automatic or manual Ground Balancing, set the sensitivity lower, or try it at another place with less interference.

• Check if the coil cable is broken.

• Turn to WET BEACH or SALT WATER MODE if you are detecting on the beach or high mineralized ground.

• When the detector is turned off, press and hold the power button until the display restarts to reset the detector to factory settings.

Quest Q30 Metal Detector

• Ensure the search coil is properly connected to the control housing
• Check the Sensitivity level – if set too low, detection depth will be greatly limited

• Ensure the volume is not set too low
• Check to see if there are headphones connected to the back of the control housing
• Plug in a set of headphones to see if there is a problem with the internal speaker
• Ensure the wireless option has not been activated (see flashing icon on the upper right side of the screen)

• Reduce the Sensitivity level
• Try using the Frequency Shift function to minimize or eliminate the chatter
• Check the Ground Balance as ground conditions may have changed
• Try another part of the site you are searching – there may be a large number of targets present
• Electrical interference in the area may be the cause. If reducing Sensitivity does not help, you may need to come back at a different time to see if the cause is no longer present.

• The overload signal indicates that the detected target is either very shallow or very large. Try lifting the coil a few inches and recheck the area.

• Typically this indicates the coil is either passing over multiple targets, an irregularly shaped object, or trash. Turn 90 degrees and wiggle the coil across the target side-to-side an inch or two. This will help you separate multiple targets or determine if it is a larger piece of trash.

Quest Q40 | Q20 Metal Detector

• Check that the coil is connected to the control box.

• Ensure the Volume is not at ZERO level.

• Try another area with less interference.

• Confirm the coil cable is not broken.

Quest X10 | X5 Metal Detector

• If the solutions above do not address the issue you are experiencing, reset the X10 | X5 to its factory settings. Turn the detector off and hold the POWER touchpad for 5 seconds. All of the icons on the screen will illuminate indicating the detector has been reset.

• Ensure the search coil is properly connected to the control housing
• Check the Sensitivity level – if set too low, detection depth will be greatly limited

• Ensure the volume is not set too low
• Check to see if there are headphones connected to the back of the control housing
• Plug in a set of headphones to see if there is a problem with the internal speaker

• Reduce the Sensitivity level
• Check the Ground Balance as ground conditions may have changed
• Try another part of the site you are searching – there may be a large number of targets present
• Electrical interference in the area may be the cause. If reducing Sensitivity does not help, you may need to come back at a different time to see if the cause is no longer present.

• This is the overload signal. Lift the coil a few inches and recheck the area.

• Typically this indicates the coil is either passing over multiple targets, an irregularly shaped object, or trash. Turn 90 degrees and wiggle the coil across the target side-to-side an inch or two. This will help you separate multiple targets or determine if it is a larger piece of trash.
