Frequently Asked Questions
Can the Discovery 3300 detect through mineralized or salty soils?
Yes, but it’s recommended to reduce sensitivity and use manual ground balancing to minimize false signals in these conditions. Consider using a smaller searchcoil for highly mineralized areas.
How does the detector respond to multiple targets in close proximity?
The Discovery 3300 may provide mixed signals when detecting multiple targets close together. Using the notch or discrimination mode can help identify desirable targets among clutter.
Does the type of battery impact detector performance?
Yes, alkaline batteries are recommended for optimal performance. Rechargeable batteries may work, but they typically have lower voltage and may reduce sensitivity and battery life.
How can I prevent electromagnetic interference (EMI) from affecting my detector?
Reduce sensitivity and avoid using the detector near power lines or large metal objects. If EMI persists, move to a different area or change the detector’s frequency by restarting it.
What’s the best way to pinpoint targets without using the pinpoint mode?
To pinpoint manually, use an “X” pattern by sweeping the searchcoil back and forth, then side to side over the target. The loudest point of the signal indicates the center of the object.
How often should I recalibrate ground balance while detecting?
Recalibrate ground balance whenever you move to a different type of soil or when the detector starts giving inconsistent signals. Changing elevation or proximity to water may also require recalibration.
