Options range from open-face searchcoil covers for smaller configurations to closed designs for larger coils, with most quality covers priced between $11 and $32 depending on specifications. You’re avoiding expensive downtime and performance degradation that occurs when dirt buildup or physical damage forces replacement purchases.
This small upfront expense eliminates hundreds in preventable repair costs, keeping you detecting without interruption.
Step-by-Step Guide to Installing Your Coil Cover
Installing a coil cover correctly guarantees maximum protection while preserving your metal detector’s performance.
Begin your coil cover installation by cleaning the search coil surface with a soft brush, removing all dirt and debris that could compromise signal clarity. Inspect for damage, then ascertain complete dryness before proceeding.
A clean, dry coil surface ensures optimal signal clarity and proper cover installation for your metal detector.
Align the cover’s edges precisely with your coil’s perimeter, starting at the back side. Snap the cover onto the outer edges gently, working progressively around the perimeter without excessive force. Push the front end back towards the coil to lock the snaps in place securely.
For DIY setups, tighten zip ties through drilled holes with clasps facing upward. Select non-metallic zip ties to avoid interference with the detector’s electromagnetic field.
Test immediately by scanning a known metal object to verify unchanged sensitivity. Check for loose edges by shaking the assembly.
These coil maintenance tips ascertain your detector performs flawlessly while you explore unrestricted terrain.
Finding the Right Coil Cover for Your Metal Detector Brand and Model
You’ll need to match your coil cover to both your detector’s brand and the specific coil dimensions, as manufacturers use different sizing standards and mounting systems.
Start by identifying your exact coil model—Garrett uses measurements like 8.5″ x 11″ DD while Minelab designates coils as V8, V10, or EQX series depending on your detector line.
Factor in your hunting conditions since rocky terrain, saltwater beaches, or high-trash areas require more durable cover materials and precise fitment to maintain target separation accuracy. For Garrett ACE series detectors, you’ll find covers in various sizes including 7×10, 6.5×9, 9×12, and 8.5×11 DD options that protect the original coils while maintaining detection performance.

Garrett users can choose covers for AT Max, AT Pro, and AT Gold configurations.
XP provides durable caps engineered for their proprietary coil designs.
Proper detector maintenance demands precision-fit covers that won’t slip during hunts. DetectorWarehouse stocks manufacturer-specific options alongside aftermarket alternatives from NEL, Detech, and Coiltek.
These brands offer cross-compatible solutions when factory covers aren’t available, ensuring your investment stays protected across beaches, fields, and relic sites without compromising detection performance.
Verify Coil Size Compatibility
Before purchasing any coil cover, measure your detector’s search coil diameter and configuration to guarantee proper fitment. Coil size directly impacts protection requirements—small coils (5-8 inches) need different covers than large coils (12-15+ inches).
You’ll find covers manufactured for specific diameter ranges, so accurate measurements prevent purchasing ill-fitting protection that compromises detection depth or slips during operation.
Consider your coil’s shape—concentric, double-D, or elliptical configurations require matching cover designs. An incorrectly sized cover creates air gaps that allow debris penetration or adds unnecessary thickness affecting ground clearance.
Match the cover precisely to your coil’s dimensions and geometry. Most manufacturers provide sizing charts correlating coil models to compatible covers. Don’t assume universal fitment exists.
Verify specifications before ordering to maintain your detector’s performance characteristics while ensuring maximum coil protection during field operations.
Consider Terrain and Conditions
Your hunting environment determines which coil cover construction will provide adequate protection and longevity. Terrain challenges like rocky ground demand strong, durable plastics that resist cracking, while sandy beaches require abrasion-resistant materials preventing scratches.
