Understanding the Garrett GTA 350: Key Features Explained

Let’s break down what makes the Garrett GTA 350 metal detector tick. Knowing its features will help you use it better. This way, you’ll find more targets.

The Search Coil: Your Detector’s “Ear”

The search coil is the part that sweeps over the ground. The GTA 350 comes with a standard coil. This coil is good for general detecting. It balances depth and coverage well.

The Control Box: The Detector’s Brain

This is where all the magic happens. The control box shows you information. It also lets you change settings. The display is clear and easy to read.

Adjustable Shaft for Comfort

The shaft of the detector can be made longer or shorter. This is important. It helps you adjust the detector to your height. A good fit means more comfortable detecting.

Built-in Speaker and Headphone Jack

You can hear targets through the built-in speaker. There’s also a headphone jack. Using headphones helps you hear faint signals. It also keeps your searching private.

Getting Started: Setting Up Your Garrett GTA 350

Setting up your Garrett GTA 350 metal detector is straightforward. Follow these simple steps to get ready for your first hunt. It doesn’t take long at all.

Step 1: Assemble the Detector

First, connect the search coil cable to the control box. Then, attach the search coil to the lower shaft. Slide the upper shaft into the lower shaft. Adjust it to your height and secure it.

Step 2: Install Batteries

The GTA 350 uses standard batteries. Open the battery compartment on the control box. Insert the batteries correctly. Make sure they are fresh for best performance.

Step 3: Power On and Initial Settings

Turn the detector on using the power button. The screen will light up. You can start with the default settings. We’ll talk about adjusting them soon.

Step 4: Ground Balancing (If Applicable)

Some detectors need ground balancing. This helps them ignore minerals in the soil. The GTA 350 has automatic ground balancing. This makes it easy to use in different locations.

Mastering the Controls: What Do They Mean?

Knowing your Garrett GTA 350 metal detector’s controls is key. Each button and setting helps you find different things. Let’s learn what they do.

Sensitivity Control

This setting affects how deep the detector can see. Higher sensitivity finds deeper targets. But it can also pick up more false signals. Start with a medium setting and adjust.

Discrimination Control

Discrimination lets you ignore junk targets. You can set it to ignore iron or foil. This helps you find more valuable items. Be careful not to discriminate too much. You might miss good targets.

Volume Control

This adjusts how loud the detector’s sounds are. You can turn it up or down. Using headphones also helps manage volume.

Mode Selection (If Available)

Some versions of the GTA 350 might have different search modes. These modes can be set for specific types of targets. For example, a “coins” mode. Or a “jewelry” mode.

Tips for Using Your Garrett GTA 350 in the Field

Taking your Garrett GTA 350 metal detector out for the first time is exciting. Here are some practical tips to help you have a successful hunt. These tips come from real-world experience.

Sweep Technique Matters

Sweep the coil slowly from side to side. Overlap each sweep by about half the coil’s width. Keep the coil as close to the ground as possible. This ensures you cover the area well.

Listen to the Signals

Pay attention to the sounds the detector makes. A clear, strong signal is usually a good target. A choppy or faint signal might be junk or a deep target.

Learn Target ID Numbers

The GTA 350 may show target identification numbers. These numbers give you a clue about what you’ve found. Different metals show different numbers. Learning these helps you decide whether to dig.

Work in Sections

When searching an area, divide it into sections. Search one section thoroughly before moving to the next. This prevents you from missing spots.

Common Targets and What They Sound Like

Understanding the sounds your Garrett GTA 350 metal detector makes is crucial. Different metals produce different tones and target IDs. This helps you decide what to dig.

Coins

Coins usually give a clear, repeatable tone. They often have a medium-range target ID number. This depends on the coin’s metal content.

Jewelry

Jewelry can be tricky. Rings and necklaces can sound different. Some might sound like coins. Others might be fainter signals.

Relics

Old relics can produce a wide range of signals. Some might be strong. Others might be weak and deep. This is where good listening skills come in.

Junk Metal

Nails, pull tabs, and foil often give choppy or low-tone signals. The discrimination setting helps filter these out. But sometimes, you might want to dig a questionable signal.

Troubleshooting Common Issues with Your Detector

Even with a great detector like the Garrett GTA 350 metal detector, you might run into problems. Here are solutions to common issues. Don’t let them stop your hunt.

False Signals

If you’re getting a lot of false signals, try lowering the sensitivity. Check for sources of electromagnetic interference, like power lines. Ensure your coil is not hitting rocks or roots.

No Signal or Weak Signal

Make sure your batteries are fresh. Check that the coil cable is securely connected. Try increasing the sensitivity slightly. If you’re in an area with high mineral content, ground balancing might be needed.

Difficulty Identifying Targets

Practice makes perfect. Spend time swinging the detector over known targets. Learn what coins and common junk sound like. Refer to your manual for target ID charts.

Essential Accessories for Your Garrett GTA 350

While the Garrett GTA 350 metal detector is great on its own, a few accessories can make your detecting experience even better. These are tools that experienced detectorists often use.

Headphones

Good quality headphones are a must. They let you hear faint signals clearly. They also block out distracting background noise. You can find comfortable, durable headphones designed for metal detecting.

Pinpointer

A pinpointer is a small, handheld detector. It helps you pinpoint the exact location of a target in the soil plug. This saves a lot of time digging and reduces damage to finds.

Digging Tools

You’ll need a good shovel or trowel. A digging tool with a serrated edge is great for cutting through roots. A sand scoop is useful for beach detecting. Always fill in your holes neatly.

Carry Bag

A sturdy carry bag protects your detector. It also makes it easy to transport. Look for one with extra pockets for accessories.

Where to Hunt with Your Garrett GTA 350

The Garrett GTA 350 metal detector is versatile. You can use it in many places. Always remember to get permission before searching on private property.

Parks and Playgrounds

These are great places for beginners. People lose coins and jewelry often. Look for areas under benches or near swings.

Your Own Backyard

You might be surprised what’s buried right under your nose. Search your yard for old coins or family heirlooms.

Beaches

Beaches are popular spots for finding rings and coins. You might need a different coil for sandy conditions. Some models of the GTA 350 are waterproof.

Old Home Sites and Fields

Research local history to find old home sites. These can be rich in relics. Always get landowner permission.

Taking care of your Garrett GTA 350 metal detector ensures it lasts for years. Simple maintenance keeps it working at its best. It’s like taking care of any other tool.

Clean After Each Use

Protect from the Elements

Avoid leaving your detector in direct sunlight for long periods. Protect it from heavy rain unless it’s specifically waterproof. Store it in a dry place.

Battery Care

Remove batteries if you plan to store the detector for a long time. This prevents corrosion. Use high-quality batteries for reliable performance.

Coil Care
