Waterproof Metal Detectors

Find Treasures Underwater

Adventurers and treasure hunters have been interested in the secrets of the ocean for hundreds of years. Under the smooth, sparkling water of rivers, lakes, and seas are coins, artifacts, and relics that tell stories of times long gone. But to find out these secrets, you need the right tool, which is an underwater metal detector.

This complete guide will help you make an informed choice, whether you're a new diver who wants to explore beaches or an experienced diver who wants to find treasures that have sunk. We can help you choose the best waterproof detectors and learn about the past of treasure hunting underwater.

The Evolution of Underwater Treasure Hunting

Treasure hunters used simple tools like dive bells and magnets for a long time before waterproof metal detectors came along. Since the invention of technology, the field has come a long way:

1960s: The first submarine metal detectors were big and couldn't go very deep. Scuba divers were the main ones who used them.

1980s: In the 1980s, pulse induction (PI) technology came out, which made it possible to find metals in places like oceans that are very mineralized.

2000s: Lighter Multi-frequency monitors came out, making them easier to carry and more accurate.

Present Day: Treasure detectors today come with GPS, waterproof headphones, and advanced discrimination features that make the hunt easier and more approachable.

Because of this change, fans all over the world now have more chances to explore the depths and find secret treasures.

Why Choose Waterproof Metal Detectors Over Regular Ones?

A lot of people want to know if they can just use their standard metal detectors near water. A few standard detectors can handle small splashes or drizzle, but they aren't made to be submerged or exposed to saltwater.

This is why waterproof types are important:

Full Submersion Capability: Waterproof devices are made to work underwater, usually at least 200 feet deep.

Protection Against Salt Corrosion: Regular detectors can quickly rust in salt water, but waterproof types are sealed to keep damage from happening.

Features Designed for Use in Water: These devices usually come with features like saltwater calibration, buoyancy control, and better visibility underwater.

Selecting a waterproof device will help you find things in more places and increase your chances of success.

Features to Look for in a Waterproof Metal Detector

When choosing the perfect detector, it's important to understand the features that matter most:

Detection Depth:

• Entry-level models can work in water up to 10 feet deep.
  
• Professional models can go down at least 200 feet, making them perfect for deep-sea dives.

Technology:

• Pulse Induction (PI): Pulse Induction (PI) technology works best in saltwater and high-mineral settings and is very good at ignoring interference.
• Very Low Frequency (VLF): This frequency works best in fresh water and can tell smaller things apart better.

Accuracy of Discrimination

• Advanced forms of discrimination help tell the difference between junk (like bottle caps and nails) and valuable metals (like gold and silver).

Plan and build

• Lightweight and ergonomic shapes make long-term use less tiring.
• It's easier to carry and keep detectors that can be folded up or made small.

Additional Accessories

• For extra ease, look for detectors that come with waterproof headphones, digging tools, and carrying cases.
