Essential Finds You Can Expect with a Garrett Waterproof Detector

With a reliable Garrett waterproof metal detector, a world of finds opens up. Beaches, lakes, and rivers are rich with history and lost items. I’ve pulled everything from ancient coins to modern jewelry from these watery depths.

The types of items you find depend on the location and depth. But Garrett detectors are sensitive enough to pick up a wide range of targets. Let’s look at some common and exciting finds.

Coins: From Pocket Change to Ancient Currency

Waterproof detectors are fantastic for finding lost coins. People drop them all the time at beaches, parks, and near water bodies. You can find modern currency like quarters and dollars, as well as older, more valuable coins. I’ve unearthed silver dimes and even some foreign coins.

The discrimination features on Garrett detectors help you ignore trash. This means more time spent finding good targets. The AT Pro, for instance, is great at identifying coin signals.

Common Coin Finds:

• Modern US coins (quarters, dimes, nickels).
• Older coins (silver dimes, wheat pennies).
• Foreign currency.
• Commemorative coins.

Finding a piece of history in the form of a coin is always thrilling. These machines make it possible.

Jewelry: Rings, Necklaces, and More

Jewelry is a common and exciting find for detectorists. People lose rings, bracelets, and earrings frequently, especially at beaches. A waterproof detector allows you to search where jewelry is most likely to be lost – near the water’s edge and in shallow areas. I’ve found beautiful silver rings and even a gold pendant.

The sensitivity of Garrett detectors is key here. They can pick up the small, distinct signals that jewelry often produces. The AT Gold’s high frequency can be especially good for fine gold chains.

Types of Jewelry Found:

• Gold rings and necklaces.
• Silver bracelets and earrings.
• Gemstone jewelry.
• Personalized lockets.

The thrill of finding a lost piece of personal adornment is immense. It’s a tangible connection to someone’s story.

Relics: Echoes of the Past

Relics are items from past historical periods. These can include old buttons, buckles, tools, or even fragments of pottery. Waterlogged environments can preserve these items remarkably well. Garrett waterproof detectors can help you uncover these pieces of history.

Searching near old settlements, historical sites, or even old shipwrecks can yield amazing relics. These finds offer a glimpse into how people lived long ago. The Sea Hunter Mark II is excellent for deeper water relic hunting.

Examples of Relic Finds:

• Old metal buttons and fasteners.
• Antique tools and implements.
• Fragments of historical metalwork.
• Shipwreck debris.

Unearthing a relic connects you directly to the past. It’s like holding a piece of a forgotten story.

Understanding Your Garrett Waterproof Detector’s Settings

To maximize your finds, you need to understand your detector’s settings. Each setting plays a role in how the detector performs. Learning these will make your hunts more successful. I always recommend reading the manual thoroughly.

Properly adjusting settings helps you filter out unwanted signals. It also helps you identify good targets more accurately. This saves you time and effort in the field.

Ground Balance: Crucial for Water and Mineralized Ground

Ground balance is extremely important, especially in wet or mineralized soil. It helps the detector ignore the signals from the ground itself. This allows it to focus on metal targets. Garrett detectors offer automatic and manual ground balancing.

For saltwater, the Sea Hunter Mark II’s PI technology handles it differently. For the AT Pro and AT Gold, manual ground balancing can be very useful in areas with black sand or high mineral content. This ensures you get the best depth and target separation.

Discrimination: Filtering Out Junk

Discrimination allows you to tell your detector to ignore certain types of metal. For example, you can set it to ignore iron or foil. This is incredibly useful for avoiding trash targets like pull tabs and nails. However, be careful not to discriminate too much.

You might accidentally filter out good targets like gold rings. I usually set my discrimination low and rely on audio tones for target identification. This helps me dig more targets and learn what each signal means.

Sensitivity: The Detector’s “Power”

Sensitivity controls how deep your detector can find targets. Higher sensitivity means greater depth. However, running your detector at maximum sensitivity can cause false signals. This is especially true in areas with a lot of electromagnetic interference or mineralized ground.

It’s often best to find a balance. Increase sensitivity until you start hearing chatter or false signals, then back it off slightly. This gives you good depth without annoying false alarms.

Essential Accessories for Waterproof Detecting

Beyond the detector itself, a few accessories can significantly improve your experience. These tools make detecting easier and more productive. I never go out without my essential kit.

Having the right gear means you can handle more situations. It also helps you recover your finds safely and efficiently.

Pinpointer: Locating Targets in the Hole

A pinpointer is a small, handheld detector. It helps you pinpoint the exact location of a target once you’ve dug a plug or hole. This saves you a lot of time and frustration. Instead of sifting through dirt, you can quickly find the item.

Garrett makes excellent pinpointers like the Pro-Pointer AT. This one is also waterproof, which is perfect for wet environments. It speeds up recovery significantly.

Digging Tools: Essential for Target Recovery

You’ll need sturdy digging tools to retrieve your targets. For wet sand, a sand scoop is invaluable. It allows you to sift through wet sand quickly. For softer ground or less accessible areas, a durable digging trowel or shovel is necessary.

Look for tools made from strong metal. They should be able to handle tough soil. Some detectorists also carry a small brush to clean off finds.

Waterproof Headphones: Hear Every Signal

While many Garrett detectors have built-in speakers, waterproof headphones are a must for underwater detecting. They allow you to hear faint signals clearly, especially in noisy environments like crashing waves. They also help keep your finds private.

Garrett offers waterproof headphones designed for their detectors. These ensure you don’t miss any subtle target tones. This is crucial for identifying small or deep items.

Tips for Successful Waterproof Metal Detecting

Detecting in water presents unique challenges and opportunities. Here are some tips based on my field experience. These will help you get the most out of your Garrett waterproof metal detector.

Applying these techniques will improve your success rate. They help you work smarter, not just harder.

Research Your Location

Before you even hit the water, do some research. Look for old maps, historical records, or local knowledge about the area. Beaches can be great, especially those near piers or popular swimming spots. Rivers and lakes can hold historical artifacts from past settlements or activities.

Understanding the history of a location can guide your search. It increases your chances of finding something significant.

Master Your Detector’s Tones

Each metal produces a different sound, or tone, from your detector. Learn to distinguish between these tones. This is your primary way of identifying targets. A good target signal is usually clear and consistent.

Practice in your yard with different metal objects. This will help you recognize target sounds. The AT Pro’s Pro Mode Audio is designed to help with this.

Work Methodically and Cover Ground

When detecting, move slowly and systematically. Cover the area in a grid pattern. Overlap your sweeps to ensure you don’t miss anything. Patience is key, especially when searching in water.

Don’t rush the process. Take your time to analyze each signal carefully. This methodical approach yields better results than random swinging.

Clean and Maintain Your Detector

After each hunt, especially in saltwater, rinse your detector thoroughly with fresh water. This removes salt and sand that can damage the components over time. Check for any damage and keep it stored properly.

Proper maintenance ensures your Garrett waterproof metal detector lasts for years. It also keeps it performing at its best. You can find maintenance guides in your detector’s manual.
