The journey of metal detecting can be incredibly rewarding, but choosing the right equipment is crucial. Many detectorists struggle to find machines that can reach those elusive deep targets. It’s frustrating to miss out on significant finds simply because your detector can’t penetrate the soil deeply enough. This guide will show you how the Garrett Infinium LS metal detector can be your ultimate solution, helping you achieve those deep, satisfying finds.

What Makes the Garrett Infinium LS Stand Out?

The Garrett Infinium LS metal detector is built for serious treasure hunters. It is designed to find targets that other detectors miss. This machine is especially good for finding old coins, lost jewelry, and valuable relics buried deep. Its robust design means it can handle tough conditions, making it a reliable companion for any expedition.

Deep Target Detection: The Infinium LS Advantage

One of the most impressive features of the Garrett Infinium LS is its ability to detect targets at extreme depths. This is thanks to its advanced Pulse Induction (PI) technology. PI detectors work differently than Very Low Frequency (VLF) detectors. They send out powerful pulses of energy into the ground. When these pulses hit a metal object, they create a return signal. The Infinium LS is designed to pick up these faint return signals from very deep targets. This gives you a significant advantage over other detectors.

This deep-seeking capability is essential for finding older, larger items that have settled deeper over time. It also means you can explore areas that have already been searched by less powerful machines. You might be surprised what lies hidden just beyond the reach of ordinary detectors.

Built for Tough Environments: Durability and Reliability

Metal detecting often takes you to challenging places. You might be searching on the beach, in salty water, or through dense undergrowth. The Garrett Infinium LS is built to withstand these harsh conditions. Its durable construction ensures it can handle being bumped, dropped, or exposed to the elements.

The detector is also waterproof, allowing you to search in shallow water and even fully submerge it. This opens up a whole new world of possibilities for finding treasures lost at the beach or in rivers. You can hunt confidently, knowing your detector is designed to last.

Key Features of the Garrett Infinium LS

The Garrett Infinium LS comes packed with features that enhance its performance and user experience. These features work together to make it a top choice for deep searching. Understanding these features will help you appreciate why this detector is so effective.

Pulse Induction (PI) Technology Explained

As mentioned, the Garrett Infinium LS uses Pulse Induction technology. PI detectors are known for their ability to ignore ground minerals and salt. This is a major advantage when detecting on beaches or in areas with highly mineralized soil. Unlike VLF detectors, PI detectors do not need complex ground balancing adjustments for these conditions.

This makes the Infinium LS particularly effective in environments where other detectors struggle. It can maintain its sensitivity to targets without being falsely triggered by mineralized ground. This means more consistent performance and fewer frustrating false signals.

Adjustable Sensitivity and Threshold Settings

The Garrett Infinium LS offers adjustable sensitivity and threshold controls. Sensitivity controls how deeply the detector can search for targets. Adjusting it allows you to fine-tune the detector’s performance based on your target depth and ground conditions. A higher sensitivity setting can find deeper targets but might also pick up more interference.

The threshold control sets a quiet background hum when no metal is detected. Adjusting the threshold can help you hear faint signals more clearly. Finding the right balance between sensitivity and threshold is key to maximizing your finds. These settings allow you to customize the detector for optimal performance in various situations.

Audio and Visual Indicators for Target Identification

When the Garrett Infinium LS detects a metal object, it provides both audio and visual cues. The audio signal is a tone that changes in pitch and volume as you sweep over the target. This helps you pinpoint the target’s location. The detector also has a visual meter that shows signal strength.

While PI detectors are not known for their precise target ID (like discriminating between different metals), the Infinium LS’s indicators are still helpful. They help you confirm a target and guide you to the precise spot for digging. This combination of audio and visual feedback aids in efficient target recovery.

Exploring Different Terrains with the Infinium LS

The Garrett Infinium LS is versatile and performs well in a variety of challenging environments. Its design makes it suitable for more than just your average park or field. Let’s look at where this detector truly shines.

Beach and Saltwater Detecting

Beaches are a prime location for lost jewelry and coins. However, the salt in the sand and water can cause problems for many metal detectors. The Garrett Infinium LS, with its PI technology, is excellent for beach hunting. It can cut through the mineralized salt and find targets effectively.

You can use it on wet sand and even in shallow saltwater. This opens up a vast area for potential finds that might be overlooked by others. Imagine finding a lost ring or bracelet right where the waves wash up!

Relic Hunting in Mineralized Ground

Old battlefields, homesteads, and historical sites are often rich in relics. The soil in these areas can be highly mineralized, making it difficult for some detectors to function properly. The Infinium LS’s PI technology makes it ideal for relic hunting in such conditions.

It can ignore the ground mineralization and focus on the metal objects. This allows you to search areas that might be considered “dead” by less capable detectors. You can uncover important historical artifacts with confidence.

Gold Prospecting Capabilities

While not its primary focus, the Garrett Infinium LS can also be used for gold prospecting. Its deep-seeking capabilities and ability to handle mineralized ground make it suitable for finding small gold nuggets. When prospecting, you often encounter highly mineralized soils. The Infinium LS can perform well in these challenging conditions.

It’s important to note that specialized gold detectors might offer finer discrimination for tiny gold flakes. However, for larger nuggets or in areas with mixed targets, the Infinium LS can be a valuable tool.

Coil Options for the Garrett Infinium LS

The coil is the part of the metal detector that interacts with the ground. Different coils are designed for different purposes. The Garrett Infinium LS can be used with various coils to optimize its performance for specific types of detecting.

Standard Search Coil

The Infinium LS typically comes with a standard search coil. This coil is a good all-around performer. It offers a balance of depth and coverage, making it suitable for general treasure hunting. It works well for finding coins, relics, and larger gold nuggets.

This coil is often waterproof, allowing you to extend your search into wet areas. It’s a reliable choice for most common detecting scenarios.

Optional Deep Seeking Coils

For those who need to reach even greater depths, optional larger coils are available. These larger coils can cover more ground with each sweep and penetrate deeper into the soil. They are particularly useful for finding very large, deep targets.

However, larger coils can sometimes be less sensitive to smaller targets. They can also be heavier and more cumbersome to swing. Choosing the right coil depends on what you are searching for and the terrain you are in.

Using Your Garrett Infinium LS Effectively

Getting the most out of your Garrett Infinium LS involves more than just turning it on and swinging it around. Proper technique and understanding its settings are crucial for maximizing your finds. I’ve learned a lot from years of swinging detectors, and here are some tips.

Mastering the Sweep Technique

The way you swing your coil is important. You want to sweep the coil slowly and steadily from side to side. Keep the coil as close to the ground as possible without hitting it. Overlap each sweep by about half the coil’s width. This ensures you cover the entire area thoroughly.

A consistent sweep speed is key. Too fast, and you might miss faint signals. Too slow, and you could become fatigued or miss targets. Practice your sweep until it feels natural and controlled.

Understanding Audio Signals

With a PI detector like the Infinium LS, the audio signals are your primary guide. Learn to distinguish between faint signals and loud ones. A faint, repeatable tone often indicates a deeper or smaller target. A loud, sharp tone usually means a shallow, strong target.

Pay attention to how the tone changes as you sweep over the target from different directions. This helps you pinpoint the exact location of the object. Sometimes, a faint repeatable signal can be a very rewarding find.

Pinpointing Your Targets

Once you get a signal, you need to pinpoint the target before you dig. Sweep the coil slowly over the area. Move the coil from front to back and side to side. The loudest part of the signal indicates the center of the target.

You can also try sweeping the coil at a right angle to your initial sweep. Where the two loudest signals intersect is usually the target’s location. Accurate pinpointing saves time and minimizes the size of your plug.

Essential Accessories for the Garrett Infinium LS User

To complement your Garrett Infinium LS metal detector, a few key accessories can significantly improve your detecting experience. These tools help you dig, recover, and manage your finds efficiently.

Pinpointer: Your Best Friend in the Hole

A good pinpointer is absolutely essential for any serious detectorist. Once you’ve located a target with your main detector, digging can be frustrating. A pinpointer is a small, handheld detector that you use inside the soil plug. It quickly locates the exact position of the target within the plug or the hole.

This saves a lot of time and reduces the disturbance to the ground. I never dig a plug without my pinpointer ready. It’s a small investment that pays off in saved time and frustration.

Digging Tools: Shovels and Trowels

You’ll need appropriate digging tools. For general use, a sturdy digging trowel or a small shovel is necessary. Look for tools made from strong steel that can cut through soil and roots. Some detectorists prefer serrated edges for cutting through tougher ground.

For beach detecting, a sand scoop is invaluable. It allows you to sift through the sand quickly and efficiently to find targets. Choose tools that are comfortable to hold and durable enough for regular use.

Headphones: Hear Every Whisper

Using headphones with your Garrett Infinium LS is highly recommended. They block out ambient noise, allowing you to hear even the faintest signals. This is particularly important in noisy environments like windy beaches or busy parks.

Good headphones also help protect your hearing by allowing you to use lower volume settings. Many detectorists find that using headphones helps them focus better on the audio cues from their detector.

Garrett Infinium LS vs. Other Deep Seeking Detectors

When looking for a deep seeking metal detector, you have several options. The Garrett Infinium LS is a strong contender, but it’s good to know how it compares. Understanding these differences helps you make the best choice for your needs.
