The best metal detector coils for different detector families
The right replacement coil is the one confirmed to work with your detector, then suited to your sites and sweep style. These picks cover several detector families and include a few complete machines for shoppers comparing full setups.
Garrett at Series 5" x 8" DD: Best for compatible Garrett AT detectors
- 5 x 8 in DD search coil
This Garrett PROformance coil is a focused replacement option for buyers whose AT detector supports this model. Confirm your exact detector model before ordering.
The Garrett at Series 5 x 8 in DD PROformance coil is the top replacement pick for buyers with a compatible Garrett AT detector. Its compact stated dimensions make it a practical option when you want a smaller coil format.
For a model-specific comparison, see Garrett AT Pro coils.
This is a coil accessory, not a complete detector. Before ordering, match your detector's exact model to Garrett's compatibility guidance, since the product name alone doesn't confirm fit for every Garrett machine.
Choose this coil when your detector is confirmed compatible and you want a 5 x 8 in DD format. If you own another Garrett family, verify fit rather than assuming the same coil works across the brand.
Nokta LG24 9.5x6" Waterproof DD Search Coil: Best for The Legend
- 9.5 x 6 in DD coil
- Waterproof
- Coil cover and mounting hardware included
Made for Nokta The Legend, this waterproof DD coil includes a cover and mounting hardware. Its stated detector compatibility makes model matching straightforward.
The Nokta LG24 is made for Nokta The Legend and measures 9.5 x 6 in. It is waterproof and includes a coil cover and mounting hardware, which helps when replacing a worn coil or adding another option for that detector.
Its named compatibility is the key buying point. Don't select it for a Simplex or another Nokta model unless the manufacturer confirms that fit.
For other Minelab models, compare best Minelab metal detector coils separately, since coil fit varies across detector families. Manticore owners can also compare Manticore coil sizes.
Nokta Simplex Ultra Waterproof Metal Detector: Best complete detector with an 11 in coil
- 11 in search coil
- Waterproof up to 16 ft (5 m)
- Carbon fiber shaft
This is a complete detector rather than a replacement coil. Consider it if you're comparing an entire setup, and note that it comes with an 11 in search coil.
The Nokta Simplex Ultra is a complete waterproof detector with an 11 in search coil, not a standalone coil. It belongs here for buyers weighing whether to replace a coil or move to a different detector setup.
Nokta states the Simplex Ultra is waterproof up to 16 ft (5 m). It also has a carbon fiber shaft that retracts to 25 in, which may help with transport and storage.
For carrying a detector, compare metal detector carry bags.
Choose it when you want a complete detector with a coil included. If you only need a replacement coil, confirm that the coil is compatible with your current machine before buying.
MINELAB V8X Double-D Waterproof 8" Search Coil: Best for confined X-TERRA PRO searches
- 8 in DD coil
- Waterproof up to 16 ft (5 m)
- Skidplate included
This smaller add-on coil is designed for the Minelab X-TERRA PRO. Minelab describes it as useful in confined spaces and sensitive to smaller, shallow targets.
The Minelab V8X is an 8 in waterproof DD coil made for the X-TERRA PRO. Minelab describes this small coil as useful in confined spaces and sensitive to smaller, shallow targets.
It operates underwater up to 16 ft (5 m), and a replacement skidplate is included. Those details make it a fit for X-TERRA PRO owners who want a small, protected coil option for wet areas or tight spots.
This coil is not presented as a universal Minelab replacement. Check your detector model before ordering, and compare other model-specific options in our Minelab coil guide.
Bounty Hunter 4-Inch Gold Nugget Search Coil: Best for tight spaces
- 4 in coil
- Waterproof
- Compatible with most Bounty Hunter detectors
The compact coil is intended for tight quarters such as spaces between rocks or under bushes. Check compatibility with your particular Bounty Hunter model.
The Bounty Hunter 4 in Gold Nugget coil is designed for tight quarters, including spaces between rocks and under bushes. Its compact size may suit cluttered areas where a larger coil is harder to sweep.
Bounty Hunter describes it as waterproof and compatible with most Bounty Hunter detectors. "Most" leaves room for exceptions, so confirm your exact machine's compatibility before choosing this coil.
The maker also describes it as intended to detect coin-sized objects up to 4 in deep. Treat that as a stated capability, not a guarantee for every target or soil condition.
Minelab Gold Monster 1000 Universal Metal Detector: Best gold detector kit with two coils
- Includes 10 x 6 in DD and 5 in DD waterproof search coils
- 45 kHz VLF
This complete Minelab detector kit includes two waterproof DD coils, one 10 x 6 in and one 5 in. It's a full setup, not a standalone replacement coil.
The Minelab Gold Monster 1000 is a complete detector kit that includes two waterproof DD search coils: a 10 x 6 in coil and a 5 in coil. It suits shoppers who want a detector and coil options in one setup, rather than a replacement coil alone.
Minelab specifies a 45 kHz VLF detector with a 24-bit signal processor. The kit also includes headphones and batteries, so compare the full package with your needs before choosing it.
For audio gear, see headphones for metal detecting.
If you're only replacing a coil on an existing Minelab detector, first check whether either included coil is compatible with that particular model.
Garrett: Best detector bundle with a Viper coil
- ACE Apex detector
- 6 x 11 in DD Viper search coil
- Multi-Flex technology
The Garrett ACE Apex is a complete detector with a 6 x 11 in DD Viper coil. Consider it when comparing detectors as well as coil options.
The Garrett ACE Apex is a complete detector with a 6 x 11 in DD Viper coil. Its coil size offers a broader sweep than the compact standalone coils in this roundup, while Garrett specifies Multi-Flex frequency options.
This pick is best for shoppers comparing a detector as well as its coil. It's not a replacement coil, and the ACE Apex's coil should not be assumed to fit a different Garrett model.
Garrett also specifies Z-Lynk wireless technology and a rechargeable battery. Those detector features may matter when comparing full setups, but they don't change the need to verify coil fit.
ULHUND Metal Detector for Adults: Best foldable detector with a DD coil
- 11 in IP68 waterproof DD coil
- Foldable design
- Control box is not waterproof
This complete ULHUND detector has an 11 in waterproof DD coil and a foldable design. The control box is not waterproof, so plan for wet conditions accordingly.
The ULHUND is a complete detector with an 11 in IP68 waterproof DD coil and a foldable design. It may suit someone who wants a portable detector for beaches, wet grass or riverbanks.
The coil is waterproof, but the control box is not. Keep the control box out of water, and follow the manufacturer's instructions for use in wet conditions.
This is a full detector kit, not a spare coil for another machine. Its stated 11 in coil size makes it a different choice from the smaller replacement coils earlier in this guide.
Bounty Hunter 10-Inch Magnum Search Coil: Best for broader Bounty Hunter coverage
- 10 in coil
- Compatible with Bounty Hunter detectors
The 10 in Magnum is a larger replacement option for Bounty Hunter detectors. Verify your detector model and mounting fit before choosing it.
The Bounty Hunter 10 in Magnum coil is intended to give compatible Bounty Hunter detectors a larger search area per sweep. It is described as compatible with all Bounty Hunter metal detectors, but confirm that the exact model and mounting setup match before buying.
Compared with the 4 in Bounty Hunter coil in this guide, the Magnum is the larger format. Consider it when broader coverage matters more than moving through tight quarters.
Choose it as a replacement or add-on only after confirming compatibility with your detector. Its 10 in size alone doesn't guarantee greater depth in every soil or target condition.
What should you compare before buying a metal detector coil?
Compare compatibility first, then coil size and the conditions where you plan to search. A coil's shape and design can affect how it handles ground response and tight areas, but only if it works with your detector.
How do detector fit and coil size affect the choice?
Your detector model sets the shortlist. Match the full model name, not only the brand, because manufacturers often make coils for specific detector families.
A smaller coil can be easier to maneuver in dense brush, between rocks and around clutter. A larger coil can cover more ground per sweep, but may be less convenient in tight areas.
What does coil design change?
Double-D coils have two overlapping windings and are common across many detector families. For more detail on the geometry and tradeoffs, see [What Is Metal Detector Coil Design?
Tips to Know](/what-is-metal-detector-coil-design/).
Design doesn't replace the need to match the detector. Also consider your usual ground and whether you hunt in wet settings, since waterproof limits vary by coil and the rest of the detector.
Should you buy a coil or a complete detector?
Buy a standalone coil if your current detector works well and you have confirmed the replacement fits. A complete detector may make more sense if you're changing machines or want a package that includes multiple coils.
The Gold Monster 1000 kit, for example, includes two waterproof DD coils. The Simplex Ultra, ACE Apex and ULHUND are also complete detectors with coils, so compare them as full setups rather than replacement parts.
How can you match a search coil to your hunting area?
Choose a coil based on access, ground conditions and the kind of targets you seek. No single size or design suits every site.
Which coil works for tight spaces?
A compact coil can help you sweep between obstacles or through dense vegetation. The 4 in Bounty Hunter Gold Nugget coil is specifically described for tight quarters, while the 8 in Minelab V8X is intended for confined spaces with the X-TERRA PRO.
If your sites are open and clear, a larger coil may be more comfortable for covering ground. Think about the space you actually sweep, not just the largest coil available.
What should you know about waterproof coils?
Waterproof ratings and limits apply to the specified component. The V8X is described for underwater use up to 16 ft (5 m), while the ULHUND's coil is waterproof but its control box is not.
Check the full detector's water limits before beach or river searches. A coil rating does not show that the control box, connector or entire machine can be submerged.
Does a larger coil always detect deeper?
No coil size guarantees greater depth in every setting. Target size, soil conditions, detector settings and coil design can all affect results.
A larger coil can cover more ground per sweep, while a compact coil can be easier to control in clutter. Use the manufacturer's stated capabilities as a guide, not a promise for every hunt.
Verdict: which metal detector search coil should you choose?
Choose the Garrett 5 x 8 in DD coil if your exact AT detector is confirmed compatible. Pick the Nokta LG24 for The Legend, the Minelab V8X for X-TERRA PRO, or a compact Bounty Hunter coil for tight spaces with a compatible machine.
If you need a complete detector, compare the Simplex Ultra, Gold Monster 1000, ACE Apex and ULHUND by their included coil and overall features. For target ideas before planning a hunt, see What Can You Find With a Metal Detector? and [How Does a Metal Detector Work?

Frequently asked questions
How do I choose the right metal detector search coil?
Start with your detector's exact make and model, then confirm that the coil is designed to fit it. After compatibility, compare coil size and the conditions you hunt in.
Smaller coils can be easier to move through tight spaces, while larger coils cover more ground per sweep.
Those tradeoffs don't replace model compatibility.
Are all metal detector coils interchangeable?
No. Coils are made to fit particular detector families or models, and a connector that looks similar does not confirm compatibility.
Check the coil maker's compatibility details against your detector's exact model name before buying.
When in doubt, ask the manufacturer or an authorized dealer.
Is a smaller search coil better?
A smaller coil can help you work among rocks, bushes or other obstacles, and some small coils are designed to respond to small, shallow targets. It also covers less ground with each sweep than a larger coil.
Choose by your typical hunting area and target goals, not size alone.
What is the difference between a DD coil and a concentric coil?
A DD coil has two overlapping detection windings arranged in a double-D shape. Coil design can affect ground response and how you sweep, but the right choice depends on your detector and site conditions.
Compare the design with your machine's compatibility guidance before choosing a replacement.
Can a waterproof coil be used underwater?
Only within the limits stated for that coil and detector. A waterproof coil does not automatically make the control box or the full detector waterproof.
For example, the ULHUND detector's coil is waterproof, but its control box is not.
Check each component's limits before entering water.
