How to Improve Metal Detector Accuracy and Find More Targets?

Metal detecting is a great way to uncover hidden treasures. But if your detector isn’t accurate, you’ll miss valuable finds. False signals, weak detection, and poor settings can make detecting frustrating.

The good news? You can improve accuracy with the right techniques. In this guide, you’ll learn how to adjust settings, use the right search methods, and find more targets.

How Metal Detectors Work?

A metal detector sends signals into the ground. When those signals hit metal, the detector alerts you. Different factors affect accuracy, including sensitivity, ground balance, and coil type. Understanding how these work will help you detect more valuable targets.

Adjust Sensitivity for Better Results

Sensitivity controls how deep your detector scans. Setting it too high can cause false signals. Setting it too low may make you miss targets.

How to adjust sensitivity:

• Start with medium sensitivity.
• Increase slowly until you get clear, stable signals.
• Lower it in mineralized soil or near power lines to reduce interference.

Set Ground Balance Correctly

Soil contains minerals that can interfere with your detector. Ground balance filters these out, making it easier to find real targets.

How to set ground balance:

• If your detector has automatic ground balance, let it adjust itself.
• For manual ground balance, start at neutral and adjust until extra noise disappears.
• In highly mineralized areas, fine-tune until signals are stable.

Choose the Right Search Coil

The coil size and type affect how well your detector works.

Coil size guide:

• Large coils – Detect deeper targets but pick up more interference.
• Small coils – Better for trashy areas and target separation.

Coil types:

• DD coils – Better for mineralized soil.
• Concentric coils – Provide good depth and pinpointing.
• Choose the right coil based on where you’re searching.

Use the Right Swing Technique

How you swing the detector matters. If you move too fast or too high off the ground, you’ll miss targets.

Best swing method:

• Move the coil in slow, overlapping sweeps.
• Keep the coil close to the ground (1-2 inches above).
• Avoid lifting at the end of each swing.

Use Discrimination to Filter Trash

Discrimination helps ignore unwanted items like nails or bottle caps.

Best settings for different hunts:

• Coin hunting: Filter out iron and foil.
• Relic hunting: Use low discrimination to avoid missing old artifacts.
• Gold detecting: Keep discrimination off to detect small nuggets.

Adapt to Your Environment

Every location requires different settings. Adjust your detector based on where you’re searching.

Beach metal detecting:

• Lower sensitivity to handle wet sand.
• Use a DD coil for saltwater conditions.

Park hunting:

• Use discrimination to avoid trash.
• Check areas near benches, pathways, and trees for lost coins and jewelry.

Relic hunting:

• Use low discrimination to find iron artifacts.
• Scan old homesteads, battlefields, and farm fields.

Maintain Your Detector

A well-maintained detector works better and lasts longer.

Maintenance tips:

• Clean the coil after each use.
• Check cables and battery connections.
• Update software if your detector allows it.

Final Thoughts

Better accuracy means more finds and less frustration. Adjust sensitivity, set ground balance, use the right coil, and perfect your swing. Practice these tips, and you’ll see a big difference in your results.
