Garrett’s Apex features Multi-Flex multifrequency technology. This allows users to choose between powerful single frequencies and simultaneous multi-frequency options. Moore explained that the frequency options enable Apex users adapt their detectors for different ground mineralization conditions, and enhance detection of metallic treasures.
Moore also noted that Apex is the only detector with such a wide range of frequency options at a MSRP below $500, which is a significant advantage over its competitors. Apex has advanced features like a high-resolution ground balanced option that allows the detector to adapt to difficult soil conditions, such as saltwater and highly mineralized soil.

Operators can adjust the overall target volume, undesired iron objects volume, detector sensitivity, search mode, target notch discrimination and frequency to remove any interference with simple, intuitive menu controls. Garrett’s ACE Apex has built-in ZLynk(tm), wireless technology that is six times faster than Bluetooth(r), allowing for the operator to use headphones without a wire.
Garrett officials describe the new treasure-finding device’s lightweight and ease of use for veterans treasure hunters as well as beginners. The most common technology used by Garrett metal detectors is called very low frequency (VLF). Two coils are embedded in a protective plate to make a VLF metal detector. The first coil emits a radio wave at a low frequency that penetrates soil. It also electronically “paints,” any metallic materials.
If metal is present, a second coil will receive the reflected signals and produce an audible tone. VLF technology is suitable for many amateur applications such as coin hunting and relic searches. Garrett metal detectors with more advanced technology use a single coil to generate a stronger magnetic pulse. This pulse can penetrate deeper and work underwater.
However, this pulse technology (PI) does not distinguish between valuable and junk metals like VLF models. Beginners often discover that there is more aluminum and scrap metal in the ground than silver or gold. Garrett metal detectors are more capable of distinguishing between valuable metals such as silver and copper from junk metals. Some models offer adjustable levels of discrimination while others are set at a fixed calibration.
A metal detector that can distinguish between aluminum and iron is sufficient for most users. An Iron Discrimination setting must be selected in order to use the Iron Audio feature. The Iron Discrim setting in this demonstration is 35. Both the silver coin and bottle cap sound good without Iron Audio. Iron Audio’s bottle cap response contains iron “grunts”, which indicate that this may be a trash target.
There is plenty of cool stuff you can find in the US, however. Green Mountain Metal Detecting’s Brad Martin has a YouTube channel that highlights some of his most memorable finds, including some Spanish Gold in the Vermont mountains. He says it is crucial to choose the right tools. A person searching for gold jewelry at a beach should use a different tool than someone looking for coins in a park.
I recommend that you visit your local hobby shop to have a conversation, they will know the best machine for you.” We also asked Martin, Barisic, and five other detectorists from Europe and the United States about their metal detectors and the current ones they are using. You’ll also need other gear to find your treasure and get it home safely. Experts who spoke with us said that you’ll need a pinpointer in order to locate your treasure after you begin digging.
Thompson describes it as a small version of a metal detector, which helps him avoid digging too many large and messy holes. You want to dig something that looks like a trap door. You simply cut the dirt along three sides and tilt it over. This way, everything will be in place when you put it back in. Modern metal detectors have a display built into the control box.
This allows you to better understand the sound and prevents you from digging up any unwanted items. Although not all displays provide the same information, most display details include the depth of the item, the iron content and the conductivity. Low conductivity means iron. Higher conductivity signals more valuable metals like silver and gold. You can also use metal detectors to amplify or “mute” iron signals.
This allows you to ignore or identify specific objects that have high iron content. Ground balancing helps eliminate signal interference from mineralized soil. Some specialty gold detectors can even be equipped with discrimination settings that reduce interference from nearby hot rocks. Due to the low frequencies (7-18 kHZ), most detectors cannot search beyond 8 inches of soil.
Some detectors are used for prospecting gold (yes, there is still gold in the hills!) can penetrate deeper. To take advantage of the highly conductive properties of gold, they use higher frequencies. It is lightweight and easy to use, making it ideal for travel and allowing you to use it for extended periods of time without tiring your arm. It’s not a toy detector, but it is aimed at beginners.
The ACE 250 VLF detector is a 6.5kHz model that’s simple to use and has many features for treasure hunting. The ACE 250’s most impressive feature is its simple display. It’s simple to read the display, even if you have never used one before. You won’t have to spend hours trying to figure out how to use the buttons. They are all clearly labeled and responsive so it doesn’t take you long to get used to them.

The ACE 250’s simplicity does not mean it lacks in features. It features a graphical Target ID and several built-in search options, including pinpointing mode, coin depth indicator, discrimination setting, and a pinpointing mode. It’s submersible so it can be used for shallow water hunting. The ACE 250 is a good choice if you are looking for a simple model to hunt coins or relics.
The ACE 250 has its flaws, but this is to be expected for a low-cost Garrett detector. Although the detector has a preset ground balance, it is not possible to manually adjust it. While this is a good option for beginners, and a common feature for entry-level detectors, it can be limiting for more experienced users. There is no volume control. Although I recommend the 250, headphones with built-in volume controls are an essential.
Also, you shouldn’t expect to get the same level of audio feedback as more expensive models. The Garrett ACE 400 metal detector is both easy to use for beginners and more advanced for experienced users. As soon as you get this metal detector, you’ll be impressed by the adjustable stem, padded grip, armrest and large visual display.
You can adjust the sensitivity to get different audio and visual feedback depending on what type of metal you are looking for. Visual display displays indicate iron, foil and gold as well as silver. This allows you to see what you have found before digging. Users have reported success with metal detectors that generate a ten-kilohertz signal, some at deeper depths than ten inches.
