Published on: October 16, 2025 | Updated on: October 16, 2025

Garrett waterproof metal detectors open up new treasure hunting possibilities, letting you explore beaches, rivers, and shorelines with confidence. Discover how these robust devices are a breakthrough for any detectorist.

Finding treasure is an exciting hobby. Sometimes, the best spots are underwater. But most metal detectors can’t handle water. This is a big problem for beachcombers and river explorers. Thankfully, Garrett has made a big step forward with their waterproof metal detectors. These machines let you search where others can’t. I’ve tested many detectors, and these waterproof models from Garrett are truly special. They offer a breakthrough in how and where we can hunt for lost items.

Why Waterproof is a Game-Changer for Metal Detecting

Being able to detect underwater or in wet conditions is a huge deal. Many valuable items are lost near water. Think about coins dropped on a beach or jewelry lost while swimming. A standard detector would be ruined by water. A waterproof model lets you safely search these areas. It expands your hunting grounds dramatically. This means more chances to find interesting things.

The Challenge of Wet Environments

Water is the enemy of most electronics. Saltwater is even worse. It can corrode metal parts quickly. Sand and mud can clog moving parts. This makes detecting in wet places very difficult. Without the right gear, you risk damaging your equipment. You also miss out on many potential finds.

Garrett’s Waterproof Innovation: What’s New?

Garrett has been making metal detectors for a long time. They know what detectorists need. Their waterproof models are built tough. They are designed to work perfectly in water. This is not just about being splash-proof. These detectors are fully submersible. You can take them into the ocean or a lake.

Key Features of Garrett Waterproof Detectors

Garrett’s waterproof detectors come with advanced features. They have excellent sensitivity to find small targets. They offer good discrimination to ignore trash. Many models have adjustable ground balance. This helps them perform well in different soil types, even wet ones.

Exploring Different Garrett Waterproof Models

Garrett offers several waterproof metal detectors. Each one is suited for different types of hunting. Some are great for beginners. Others are for more experienced treasure hunters. Knowing the differences helps you pick the right one.

The All-Terrain Champion: Garrett AT Pro

The Garrett AT Pro is a very popular choice. It is fully submersible up to 10 feet. This makes it perfect for shallow water and wet sand. It has a high frequency for finding small gold nuggets. It also works well for coins and relics. Its Fast Target ID technology helps you identify targets quickly.

For Serious Prospectors: Garrett AT Gold

The Garrett AT Gold is designed for gold prospecting. It operates at a higher frequency than the AT Pro. This is better for detecting tiny gold pieces. It is also fully submersible. This lets you search streams and riverbeds for gold. It offers excellent sensitivity and ground balance.

The Versatile Explorer: Garrett Sea Hunter Mark II

The Garrett Sea Hunter Mark II is built for saltwater. It uses Pulse Induction (PI) technology. This technology works very well in salty water. It ignores the signals from salt minerals. This detector can go as deep as 200 feet. It is ideal for diving and offshore hunting.

Using Your Garrett Waterproof Metal Detector Effectively

Getting a waterproof detector is just the start. You need to know how to use it. Proper technique will help you find more. It will also protect your gear. Always read the manual for your specific model.

Submersion and Handling Tips

When you submerge your detector, do it slowly. This allows the water pressure to equalize. Make sure all seals and battery compartments are closed tightly. After use, rinse your detector with fresh water. This is especially important if you used it in saltwater. Salt can cause damage over time.

Coil Selection for Underwater Hunting

The coil is the part that senses metal. Different coils work better in different situations. For general underwater hunting, a standard coil is often fine. For very trashy areas or deeper targets, you might consider a specialized coil. Garrett offers various coils for their detectors. Always check compatibility with your model.

Essential Accessories for Waterproof Detecting

Having the right accessories makes detecting easier. Especially when you are near or in water. These tools help you find, recover, and manage your finds.

Pinpointers: The Small Target’s Best Friend

A pinpointer is a small handheld detector. It helps you pinpoint the exact location of a target. This is very useful when digging in sand or mud. Garrett makes excellent waterproof pinpointers like the Garrett Pro-Pointer AT. This tool saves a lot of time and effort.

Digging Tools for Wet Conditions

You’ll need tools to dig your finds. For wet sand, a scoop is very helpful. It lets you sift through the sand easily. For softer mud, a small trowel or digging tool works well. Ensure your tools are also corrosion-resistant.

Carrying and Storage Solutions

Protecting your detector is important. Use a waterproof bag or case. This keeps it safe when you are not using it. After rinsing, allow your detector to dry completely before storing. Proper care ensures your detector lasts longer.

Where to Hunt with Your Garrett Waterproof Detector

The possibilities are vast with a waterproof detector. Think about all the places you couldn’t search before. These locations often hold lost treasures.

Beaches: A Treasure Trove of Lost Items

Beaches are prime locations. People lose coins, jewelry, and other items daily. You can search the dry sand, wet sand, and even shallow water. Always check local regulations about metal detecting on beaches. Some areas have restrictions.

Rivers and Lakes: Uncovering History

Rivers and lakes can hold old coins and artifacts. People have been using waterways for centuries. You might find old currency or historical items. Be aware of water currents and depth. Always practice water safety.

Shorelines and Docks: Accessible Finds

The areas around docks and piers are often fruitful. Items can fall off boats or be dropped by people. These spots are usually easy to access. They are great for beginners to practice.

Maintaining Your Garrett Waterproof Metal Detector

Proper maintenance is key to longevity. This is especially true for waterproof gear. Following a few simple steps will keep your detector in top shape.

Cleaning After Each Use

Always rinse your detector with fresh water after every use. Pay attention to nooks and crannies. Use a soft cloth to dry it. If you detect in saltwater, a more thorough rinse is needed.

Checking Seals and O-Rings

Regularly inspect the seals on battery compartments and cable connections. Make sure they are clean and free of debris. Replace any worn or damaged seals. This is crucial for maintaining waterproof integrity.

Battery Care

Use the recommended batteries for your detector. Remove batteries if you plan to store the detector for a long time. This prevents corrosion from battery leakage.

Garrett Waterproof Metal Detector: A Smart Investment

Investing in a Garrett waterproof metal detector is wise. It opens up a whole new world of detecting. You can explore more places. You can find more types of treasures. The durability and advanced features make it a reliable tool.
