One of the most crucial components to upgrade is coil upgrades for your metal detectors, which is essentially listening for buried valuables. 

Upgrading your coil can make a substantial difference to your detecting abilities. Here’s a guide by GoldXtra to understanding coil upgrades for your metal detectors.

1. Understanding the Importance of Coils

The depth and sensitivity of your metal detector depend on the size of your coil.

Before diving into upgrades, it’s essential to understand what the coils are and what purpose they serve.

  • Detection Depth: The coil determines how deep your detector can detect into the ground.
  • Sensitivity: It impacts the sensitivity towards different metal types.

  • Coverage: The shape and size of the coil influence the ground area you cover with each sweep.

2. Types of Coil Upgrades

To effectively upgrade your coil you need to understand beforehand how they work and whether or not they will help in your particular goal.

Different terrains and targets call for various coils. Here’s a rundown of the primary coil upgrades available, their benefits, and their drawbacks:

  • Larger Coils:
    • Benefits: Covers more ground and detects deeper targets. Excellent for vast, open spaces.
    • Drawbacks: Might be less sensitive to smaller targets and can be heavier to carry.
  • Concentric Coils:
    • Benefits: Provide even and well-balanced sensitivity and depth.
    • Drawbacks: Less effective in mineralized soils.
  • Double-D Coils :
    • Benefits: It is great for challenging terrains like mineralized grounds and offers excellent ground coverage.
    • Drawbacks: Might have less depth than concentric coils in certain conditions.
  • Small Sniper Coils:
    • Benefits: Perfect for trashy areas, allowing for better target discrimination. They are also great for tight spaces.
    • Drawbacks: Cover less ground due to their size.

3. Factors to Consider When Upgrading

Upgrading your coil isn’t just about picking a new, shiny option. You need to consider:

  • Compatibility: Ensure the coil you’re looking for is compatible with your metal detector model.
  • Terrain: Your regular hunting grounds (beaches, parks, or mineral-rich areas) can determine the best coil type.
  • Weight: A lighter coil can be easier on the arm during long detecting sessions, while a heavier one might offer deeper detection.
  • Budget: Like any upgrade, there’s a range of prices. Weigh the benefits against the costs to find a coil that offers good value for money.

4. Care for Your New Coil

Once you’ve upgraded, you can make sure that your coil stays in tip-top shape for a long time by taking proper care of it which includes:

  • Regular Cleaning: After each hunt, clean your coil from dirt and debris. This ensures optimal performance.

  • Coil Covers: Consider getting a coil cover. It acts as a protective shield against scratches and minor impacts.

  • Storage: Store your coil in a dry place. If it’s a backup or secondary coil, ensure it’s kept safely without excessive weight pressing on it.


In the world of treasure hunting, the coil plays one of the most important roles. So upgrading it can be very important if you want to succeed in your goal of finding treasure.

Remember, the right coil upgrade hinges on your specific needs, detecting habits, and the terrains you frequent.

Now that you are equipped with the right information about coil upgrades for your metal detectors, we hope you can make an informed decision on which coil suits your needs.
