Beach hunting puts a metal detector close to wet sand, splashes, and sometimes shallow water, so the first thing to check is what is actually waterproof. The detectors below have waterproof search coils, but their control boxes are not designed to be submerged. That makes them options for dry sand, damp shorelines, and shallow-water searching with the coil—not for underwater use with the whole detector.
Our picks range from simple, beginner-friendly designs to models with more search modes and portability features. Compare the coil size, controls, fit, and included gear to find the right match for the way you plan to hunt.

Our Picks: Best Waterproof Metal Detectors For Beach Hunting reviews
1. Gbnryg Professional Metal Detector: A Feature-Rich Kit for Family Outings
The Gbnryg combines a 12-inch IP68 search coil with five modes: All-Metal, Disc, Memory, Jewelry, and Pinpoint. The larger coil can cover more ground per sweep than the smaller coil on the Bounty Hunter, which may be useful when scanning broad stretches of beach. The product description says it can detect a quarter-sized object up to 12 inches deep under suitable conditions; treat that as a stated capability, not a guaranteed depth for every target or beach.
Its stem adjusts from 21 to 53 inches, and the backlit display is intended to make readings easier to see in low light. The included headphones, digger, backpack, and two batteries make this a ready-to-go package. The built-in memory also saves custom settings between uses, according to the supplied product details.
The main limitation is important for beach use: only the search coil is waterproof. Keep the control console out of the water, and do not treat the detector as a fully submersible unit. The five modes offer flexibility, but beginners may need time to understand which settings are useful for a particular beach and target.
Pros:
- 12-inch IP68 waterproof coil for shallow-water and wet-shoreline searching
- Five modes, including Jewelry and Pinpoint
- Adjustable stem and backlit LCD
- Includes batteries, headphones, a digger, and a backpack
Cons:
- The control console is not waterproof
- The number of modes may take practice to use well
Verdict: Choose the Gbnryg if you want a broad set of features and included accessories for family beach outings, while keeping the control box safely dry.
2. BOXTREN Metal Detector: Five Modes and a Foldable Stem
The BOXTREN uses a 12-inch IP68 DD coil and offers All-Metal, Disc, Notch, Memory, and Pinpoint modes. Its mode selection gives you options for broad detection, target filtering, and locating a signal before digging. The product description also highlights a digital signal processor and claims a detection depth of up to 12.8 inches in suitable conditions. Actual results can vary with the target, soil, and other conditions.
The stem folds for transport and adjusts from 20 to 53 inches. A backlit LCD shows target ID, depth, and battery status, while audio tones provide another way to follow signals. Headphones, a shovel, a backpack, and two AA batteries are listed as included, so the package covers several basic needs for a day outdoors.
Like the other coil-only waterproof picks, this model is not a choice for submerging the full detector: its control box is described as splash-proof, not waterproof. Its feature set is a step up from the simpler Bounty Hunter, but shoppers who want a compact one-piece folding design may prefer the ULHUND.
Pros:
- 12-inch IP68 DD coil
- Five modes, including Notch and Pinpoint
- Foldable stem and adjustable length
- Backlit LCD and included headphones, shovel, and backpack
Cons:
- Control box should not be immersed
- More settings may be unnecessary for someone seeking very simple operation
Verdict: The BOXTREN is a good fit if you want several target-selection modes, a foldable stem, and a large waterproof coil for shoreline searches.
3. Bounty Hunter TK4 Tracker IV: A Straightforward Choice for New Hunters
The Bounty Hunter TK4 Tracker IV takes a simpler approach than the other detectors here. It has three detection modes—All-Metal, tone, and discrimination—along with adjustable sensitivity and analog controls. That smaller feature set can be appealing if you would rather learn a few basic controls than work through five search modes.
Its 8-inch waterproof coil is smaller than the coils on the other picks. A smaller coil covers less ground with each sweep, but the straightforward design may suit casual searching around the shoreline, in damp sand, or in shallow water. The supplied information does not specify a waterproof control box, so keep the electronics dry and do not submerge the detector.
This is the most basic option in the group, and it does not list the larger LCD, multiple accessories, or expanded mode selection found on several competitors. If you want a feature-rich detector with a larger coil, consider the Gbnryg or BOXTREN instead. If ease of use is your priority, the TK4 is the more focused choice.
Pros:
- Simple analog controls and three detection modes
- Waterproof 8-inch search coil for shallow-water use
- Adjustable sensitivity
- Designed for use by adults and kids
Cons:
- Smaller coil than the other listed models
- Fewer modes and display features than the more advanced picks
Verdict: Pick the Bounty Hunter TK4 if you want an uncomplicated detector for casual beach and outdoor searches and do not need a large display or extensive settings.
4. Raynesys Metal Detector: A Long-Adjusting Stem for Shared Use
The Raynesys has a 10-inch IP68 waterproof coil and five modes: All-Metal, Disc, Memory, Jewelry, and Pinpoint. The product description says its coil can detect a quarter up to 12 inches deep under suitable conditions. As with any advertised depth, real-world results depend on factors such as the size and position of the target and the ground being searched.
One standout detail is the stem’s wide adjustment range, from 19 to 59 inches. That gives several people more flexibility to share the detector, and the stem retracts for storage in the included backpack. The kit also lists two 9V batteries, a digging shovel, and a headset. A backlit LCD shows target information, and the soft elbow support is intended to help during longer searches.
The Raynesys is a practical family-oriented option, though it has a smaller coil than the 12-inch Gbnryg and BOXTREN. Its control box is not waterproof, so the coil can be used in shallow water while the console stays above the waterline. The supplied details do not mention a dedicated saltwater setting.
Pros:
- 10-inch IP68 coil for beach and shallow-water searches
- Five modes, including Jewelry and Pinpoint
- Stem adjusts from 19 to 59 inches
- Includes batteries, a shovel, a headset, and a backpack
Cons:
- The control box is not waterproof
- Coil is smaller than the 12-inch options in this list
Verdict: Consider the Raynesys if several people of different heights will share one detector and you want a useful set of modes and accessories.
5. ULHUND Foldable Metal Detector: A Portable Design with a DD Coil
The ULHUND is built around portability. It weighs 2.4 pounds, folds for storage, and has a built-in cable design that avoids the cable-wrapping step described for traditional models. Its stem adjusts from 22 to 60 inches, and the package includes a backpack for carrying it to the beach or another search area.
The 11-inch IP68 DD coil is waterproof for shallow-water and shoreline searches, while the control box is not. The product description says the DD coil is designed to help with interference and signal stability, and it lists four search modes: All Metal, DISC, Notch, and Pinpoint. It also claims detection up to 12.8 inches in suitable conditions; that should not be treated as a guaranteed depth for every beach target.
Compared with the Gbnryg and BOXTREN, the ULHUND has one fewer listed mode, but its folding build and stated low weight may matter more if you carry your detector on foot. The product information provided does not list included headphones or a digging tool, so check the package details if those accessories are important to you.
Pros:
- Foldable design with a built-in cable
- 11-inch IP68 DD coil
- Lightweight build and adjustable stem
- Four modes, including Notch and Pinpoint
Cons:
- The control box is not waterproof
- Fewer listed modes and accessories than some competing kits
Verdict: The ULHUND makes sense if easy packing and a lightweight, foldable frame matter more to you than having the largest coil or the most modes.
How to Choose a Waterproof Metal Detector for Beach Hunting
Check Which Parts Are Waterproof
A waterproof coil does not mean the whole detector can go underwater. Several models here clearly state that the control box is not waterproof, and the BOXTREN control box is described as splash-proof rather than submersible. Before hunting near the waterline, confirm the limits for the exact model and keep the console out of water unless its instructions explicitly allow immersion.
Match the Coil Size to Your Search Area
A larger coil generally covers more ground with each sweep, which can be useful when scanning a wide stretch of sand. The picks here range from the Bounty Hunter’s 8-inch coil to 12-inch coils on the Gbnryg and BOXTREN. Coil size is only one factor, though: consider how easy the detector feels to sweep and how much control you want when searching a smaller area.
Think About the Kind of Beach You Visit
Dry sand and shallow water at the edge of a beach are different from wet, mineral-rich sand or surf. The product details list waterproof coils and general beach use, but do not describe dedicated saltwater ground-balance features for these models. If you plan to search wet salt sand often, check the manufacturer’s guidance about that specific environment rather than assuming a waterproof coil guarantees stable operation.
Choose Modes You Will Actually Use
All-Metal mode is meant to respond to metal broadly, while Disc or Notch modes can help filter or select targets. Pinpoint mode is intended to help locate a signal more precisely before digging. Five modes can provide more control, but they may take longer to learn. If you want simpler operation, the Bounty Hunter’s three-mode layout may be a better fit.
Get the Right Fit for Comfortable Sweeping
Beach hunts can involve repeated sweeps over a large area, so an adjustable stem and a comfortable grip matter. The Raynesys and ULHUND offer particularly broad stated adjustment ranges, while the other models also adjust for different users. If the detector will be shared, compare the full range with the heights of the people who plan to use it.
Consider Portability and Included Gear
A detector that folds or comes with a backpack may be easier to carry and store. The ULHUND emphasizes a foldable design, while the Gbnryg, BOXTREN, and Raynesys list backpacks and various accessories. Check whether the kit includes the items you need, such as headphones, batteries, or a digging tool, so you can plan for anything not listed.
Keep Advertised Depth Claims in Perspective
Some product descriptions state maximum detection depths, but those figures should not be read as guaranteed results on a beach. Target size, position, and ground conditions can all affect detection. Use depth claims as a comparison point, not as a promise that every coin or piece of jewelry will be found at that depth.
Frequently Asked Questions
Can these metal detectors be fully submerged?
The supplied details describe waterproof search coils, not fully waterproof detectors. Several models explicitly say the control box is not waterproof. Keep the control box above water and follow the manufacturer’s instructions for the specific model.
Can I use these detectors on wet sand?
The product descriptions list beach or shoreline use, but they do not establish that every model is tuned for wet salt sand. Check the manufacturer’s guidance for your intended beach conditions, especially if you plan to search near surf or on wet sand.
Which detector has the largest coil?
The Gbnryg and BOXTREN list 12-inch coils. The ULHUND has an 11-inch coil, the Raynesys has a 10-inch coil, and the Bounty Hunter TK4 has an 8-inch coil.
Which option is simplest for a beginner?
The Bounty Hunter TK4 has three modes and analog controls, making it the most straightforward pick on this list. A simpler layout can be easier to learn, though it offers fewer settings than the five-mode models.
Do any of these models include headphones or digging tools?
The Gbnryg, BOXTREN, and Raynesys list headphones and a digging tool or shovel in their packages. The supplied ULHUND details do not list those accessories, and the Bounty Hunter description does not specify them.
Are the stated detection depths guaranteed?
No. Depth figures in product descriptions are claims under suitable conditions, not guarantees for every target or beach. Results can vary with the target and ground conditions.
Final Recommendation
For a versatile beach-hunting kit, the Gbnryg stands out with its 12-inch waterproof coil, five modes, and included accessories. Choose the BOXTREN if its foldable stem and Notch mode appeal to you, the Bounty Hunter if you prefer simple controls, the Raynesys if several people need a wide adjustment range, or the ULHUND if portability is your top priority. Whichever you choose, remember that a waterproof coil does not make the control box safe to submerge.
