Metal Detecting Iron Falsing & Masking Prevention Tool

Diagnose and prevent iron falsing and target masking based on site, detector settings, and coil type to recover masked good targets in trashy areas.

Helps to navigate trashy sites.

‍

We ask for detector type, site conditions, current symptom, discrimination setting, coil type, sensitivity level, and experience level because these reduce falsing (e.g., low disc in iron). These inputs recover masked targets. Limitation: the tool uses general settings and may not eliminate all falsing; dig high-tone signals.

Iron Falsing Diagnosis and Solutions

Cause of Frequent Falsing

Frequent falsing or chirping from your metal detector can primarily be attributed to the following factors:

1. High Iron Content in Soil: Areas with a lot of iron debris can cause detectors to pick up unwanted signals.
2. Low Discrimination Settings: A low discrimination setting can lead to detecting both valuable targets and iron trash.
3. Coil Type: A DD coil is sensitive to small targets, which can result in detecting more trash and iron.
4. Ground Conditions: Highly mineralized ground can interfere with signal clarity, leading to falsing.

Step-by-Step Settings Adjustments

1. Increase Discrimination:
   • Adjust the discrimination setting higher to filter out iron signals. Start at a medium level and gradually increase until you find a balance that still allows for valuable targets.
2. Adjust Sensitivity:
   • Lower the sensitivity setting slightly. This will help reduce the detection of small iron particles, which often cause falsing.
3. Use Ground Balance:
   • Perform a manual ground balance to adjust for mineralization in the soil. Follow your detector's manual for the specific steps, but generally:
     • Raise the coil above the ground and press the ground balance button.
     • Lower the coil to the ground and listen for changes in tone.
     • Adjust until the detector becomes stable.
4. Change Frequency Settings:
   • If your detector has multi-frequency options, try different frequencies to see which provides the clearest signal with less falsing.
5. Coil Height Adjustment:
   • Keep the coil as close to the ground as possible without touching it. This can help improve target identification and minimize interference.

Understanding Masking Physics

Masking occurs when a large iron target obscures the signal from a smaller, valuable target nearby. The physics behind this involves electromagnetic fields emitted by the coil interacting with the ground and surrounding objects. Iron and other highly conductive materials can create a dominant signal that overwhelms the detector's ability to pick up weaker signals from smaller or less conductive objects.

Key Points:

• Signal Overlap: When two targets are close together, the detector may only receive the stronger signal.
• Ground Mineralization: High mineral content can create noise, making it difficult to distinguish between different signals.

Recovery Tips

1. Use a Pinpointer: After detecting a target, use a pinpointer to precisely locate it, especially in trash-heavy areas.
2. Digging Techniques: Use a small shovel or trowel to carefully dig around the detected signal, minimizing disruption to the surrounding area.
3. Re-scan the Area: After recovering a target, re-scan the area to catch any other potential targets that may have been masked.
4. Practice Patience: Frequent falsing can be frustrating. Take your time and listen carefully for changes in signal tone that might indicate valuable targets.

Prevention Tips

• Choose Search Locations Wisely: Avoid heavily trash-laden areas until you are more experienced.
• Regularly Adjust Settings: Continuously tweak your settings based on the terrain and conditions.
• Practice: Spend time familiarizing yourself with your detector's sounds and signals in different environments.
