How to Choose the Best Waterproof Metal Detector?

If you’re dreaming of uncovering buried coins on the beach or relics lost to riverbeds, choosing the best waterproof metal detector can be your gateway to adventure. But with so many models on the market, how do you pick the one that’s perfect for your needs?

Know Your Terrain: Where Will You Be Detecting?

First and foremost, ask yourself: Where do you plan to use your metal detector? Waterproof detectors come in two main types—water-resistant and fully submersible.

• Water-resistant detectors are ideal for sandy shores or shallow streams where splashes are expected but full submersion is not.
• Fully submersible detectors, on the other hand, can be used underwater, often up to depths of 10 to 200 feet depending on the model.

Pro Tip: If scuba diving or snorkeling is in your plans, look for models with IP68 waterproof ratings and adjustable underwater audio or vibration alerts.

Sensitivity and Depth: Don’t Miss a Thing

Your detector’s sensitivity determines how well it picks up small or deeply buried objects. While most models let you adjust sensitivity manually, higher-end detectors automatically calibrate based on ground conditions—a huge advantage in saltwater environments.

Look for:

• Frequency range (5–15 kHz is great for general detecting; 20+ kHz is better for gold nuggets)
• Adjustable gain settings
• Multi-frequency capabilities (e.g., Minelab Equinox 800)

Why does this matter? Because depth and sensitivity often make the difference between walking away with a rusty nail—or a rare coin from the 1800s.

Discrimination Features: Find the Good, Ignore the Junk

Have you ever spent 10 minutes digging only to find a bottle cap? That’s where discrimination comes in. This feature helps filter out undesirable targets such as iron or foil.

Seek out models with:

• Customizable target ID systems
• Tone ID (so you can hear the difference)
• Notch discrimination, letting you accept or reject specific metal types

From personal experience, once I switched to a detector with advanced notch filtering, my finds improved dramatically—and my frustration level dropped just as fast.

Battery Life and Charging Options: Stay Out Longer

There’s nothing worse than running out of juice just as you’re zeroing in on a promising signal. When evaluating waterproof metal detectors, pay close attention to battery life and power options.

Recommended:

• At least 10+ hours of run time
• USB or magnetic charging for convenience
• Spare battery packs if you’re on long excursions

Some models even offer solar-powered charging cases, which I’ve found incredibly helpful during multi-day beach trips.

Ergonomics and Weight: Comfort Is Key

Don’t underestimate the importance of comfort, especially if you plan on detecting for hours at a time. A detector might perform brilliantly but leave your arm aching if it’s poorly balanced or overly heavy.

Look for:

• Adjustable shafts
• Lightweight builds (under 3.5 lbs)
• Comfortable grips and padded armrests

The Nokta Makro Simplex+, for example, is lightweight, adjustable, and ideal for beginners. I lent one to a friend for a beach hunt—and he ended up buying his own the next day.

Display and Interface: Stay in Control

Clear visibility underwater or in bright sunlight makes all the difference. Choose a detector with a backlit LCD screen, intuitive controls, and a menu that doesn’t require a Ph.D. to understand.

Advanced features to consider:

• Digital target ID
• Real-time depth indicators
• Mode presets (e.g., beach, relic, coins)

Don’t shy away from user-friendly interfaces—even seasoned detectorists appreciate a machine that makes life easier.

Frequently Asked Questions When Selecting the Best Waterproof Metal Detector

1. What is the best waterproof metal detector for beginners?

The Nokta Makro Simplex+ is often recommended for beginners. It’s fully submersible up to 10 feet, lightweight, and easy to use with a clear display and preset search modes. Its affordable price and solid performance make it a great entry-level detector for those new to water hunting.

2. Can I use a waterproof metal detector in saltwater?

Yes, but not all waterproof detectors handle saltwater well. Saltwater can cause false signals in some models. For saltwater use, choose detectors with multi-frequency technology like the Minelab Equinox 800 or those with *ground balance settings specifically for mineralized soil and saline environments.

3. What does “fully waterproof” mean in metal detectors?

“Fully waterproof” means the detector can be completely submerged in water without damage, including the control box and coil. Always check the depth rating—some detectors are waterproof to only 10 feet, while others like the Garrett Sea Hunter Mark II can go much deeper.

4. What features should I prioritize in a waterproof metal detector?

Key features to look for include:

• Submersion depth rating
• Discrimination and target ID
• Adjustable ground balance (especially for saltwater)
• Battery life
• Lightweight, ergonomic design
  These ensure you’ll have both comfort and effectiveness while detecting in wet environments.

5. Is there a difference between water-resistant and waterproof detectors?

Yes. Water-resistant detectors can withstand splashes and rain, but they shouldn’t be submerged. Waterproof detectors are designed to be used underwater. For riverbeds, beaches, or diving, always choose a fully waterproof model.

6. Can I use a waterproof metal detector on land too?

Absolutely. Most waterproof metal detectors work perfectly on dry land. In fact, many users prefer waterproof models for all environments because they are more rugged and resistant to weather and dust.

7. What’s the best waterproof metal detector for scuba diving?

The Garrett Sea Hunter Mark II and the Minelab Excalibur II are excellent for scuba divers. These detectors are rated for deeper depths and designed with waterproof headphones and vibration features, making them ideal for underwater exploration.

8. Do waterproof detectors have waterproof headphones?

Not all of them. While some include waterproof headphones, others require a separate purchase. If you plan to fully submerge your head, make sure the model supports waterproof audio accessories or vibration feedback.

9. How much should I expect to spend on a quality waterproof metal detector?

Prices vary based on features and depth capability.

• Entry-level: $250–$400 (e.g., Simplex+)
• Mid-range: $500–$900 (e.g., Garrett AT Pro)
• High-end/professional: $900+ (e.g., Minelab Equinox 800, Excalibur II)
  Spending more typically means better depth detection, discrimination accuracy, and durability.

10. How deep can waterproof metal detectors detect?

Detection depth depends on the object size, soil conditions, and the detector’s frequency. Generally:

• Small coins: 6–12 inches
• Larger relics: 2–3 feet
  Water depth ratings (for submersion) and detection depth (in soil or sand) are different, so check both before buying.

Conclusion

When it comes to finding the best waterproof metal detector, the right choice depends on your goals, environment, and experience level. Our hands-on tests revealed standout models that excel in various conditions—whether you’re a beginner beachcomber or a seasoned underwater explorer.
