The Anfibio is a dual-purpose Metal detector that may be used both on land and in water without the risk of causing harm to the detector. It possesses all of the characteristics that qualify it as a “do-it-all machine.”
Multiple frequency and selective detectors are difficult to distinguish from one another, and marketing terminology doesn’t help matters.
Although the Anfibio has a wide range of frequencies at its command, it can only use one of them at a time, classifying it as a single frequency detector. True multifrequency detectors are capable of operating at the same time.
Five, fourteen, and twenty kilohertz are the single frequencies used in this concept. Each sort of frequency will assist you in narrowing down your search for coins, fine jewelry, and maybe even gold chunks.
The Anfibio is reasonably priced for the detectorist who needs a single machine that can do various tasks. A submersible depth of 16.4 feet, nine pre-programmed search modes, and expert user-adjustable parameters distinguish it from the competition.
Because it removes the need to navigate through many panels to make a change, you’ll find the one menu display an appealing feature.
Time is money, therefore spend less time messing about and more time digging up treasure. When you’re underwater, the vibrating feature will come in for giving you that extra assurance that you’ve hit something solid.
With its single tone and lack of discriminating, it is similar to the All Metal mode. Still, it excels in regions with high mineralization, where false signals and background chatter frequently cover excellent targets.

Single Menu Display.
13. Garrett Sea Hunter Mark II Underwater Metal Detector:
Surprisingly, the Sea Hunter Mark II is a pulse induction metal detector with a retail price of less than $1000. The manufacturer’s warranty only covers the Sea Hunter for one year after purchase.
To properly care for and maintain a detector that will be exposed to demanding circumstances as a result of its submersion in water, you should take extra precautions.
The Mark II detector has been designed to withstand submersion up to 200 feet below the water’s surface. Divers will appreciate being able to go deeper and retract the duration of their lives as needed.
While the knob controls allow for simple changes while the device is submerged, they do not provide a digital display for visual information. Visual data would be impossible to utilize anyhow when you’re that far down the rabbit hole. It’s a good thing the headphones and jack that come with the package are waterproof.
A pulse induction detector’s strengths include depth sensing and sensitivity, while its faults are discrimination and sensitivity. Even though there is some differentiation, it is still mostly a one-tone detector, with your shovel serving as the most potent discriminator.
Purchasing the Sea Hunter Mark II will provide you with excellent value for your money. Exceptional submergence level, pulse induction, and consistent quality from a name you can rely on, with detectors built in the United States.
The AT Pro is entirely underwater and submerged to a depth of 10 feet, making it an excellent detector for searching in and near ponds, canals, streams, lakes, and even the ocean.
Because it was specifically developed for underwater hunting. It is remarkable to discover a detector like the AT Pro that is completely submersible despite many detectors having a waterproof coil as standard. Considering this, the Pro isn’t particularly well adapted to diving situations. It is possible to purchase separate detectors with a considerably higher depth rating developed expressly for scuba diving or shipwreck searching; however, we will get to that in a minute.
When used in normal audio mode, the AT Pro provides a full-range audio response with no distortion. This implies that the sound of the detector that switches on after scooping up an area will always be continuous and steady, no regardless of what the object is or how deep the object is located in the environment.
When you are in this mode, you will hear from your objective and receive information on the type of thing you have discovered. For example, if you step away from an object, the audio will weaken, and if you go closer to the target, the audio will become stronger.
A higher frequency has a variety of advantages over a lower frequency. First and foremost, this detector excels in picking up even the tiniest of objects while also providing great target separation. Its higher frequency also makes it better suited for identifying gold chunks than some of the other VLF versions, thanks to the device’s excellent ground balance function, which is particularly effective in this application.
The AT Pro also has high-resolution iron detection levels ranging from 1 to 40, which may be adjusted. Using the appropriate discriminating level setting, you’ll have the ability to filter out unwanted things like rusty nails and other debris.
Simple as it seems, setting the appropriate discrimination level is as simple as going to the iron differentiation menu and pressing the appropriate button (+) or (-). While this is true, it’s also vital to remember that you shouldn’t make your search parameters too high, or you’ll lose out on important goods or metals that you’ve been seeking all along.
Hovering the search coil over your possible target and pressing the eliminate button is yet another way of filtering your search so that you don’t end up detecting unintended items. Because you’ll most likely lose out on other suitable targets, this strategy is a little risky, but if you’re consistent and direct in your approach, you should consider using it.
The iron audio capability, comparable to pro mode audio, was absent in entry-level or beginning Garrett detectors until recently. When the system is active, you can hear discriminating iron in a way that makes you certain that there is iron beneath the surface.
It will be obvious whether you are collecting iron content when extremely low and groaning tones emerge from your gadget. It is most likely garbage at this point. Hunters of all kinds, but particularly coin collectors, will find this feature quite beneficial.
The digital target ID function also referred to as the target identification feature shows the potential identification and ranges from 1 to 99. For example, if or when you discover an iron item, the TID value will be extremely high, and the pointer will be located on the absolute right side of the scale.
Ground balance the sensor in mineralized soil as soon as possible.
Ear cushions are included in the purchase of these headphones.
Within a year, there may be problems with the headset.
A little on the expensive side.
15. FYSMY Fully Waterproof Pinpoint Metal Detector:
A portable underwater metal detector such as the FYSMY waterproof is the gadget to choose if mobility is a high requirement. Because of the tool’s long neck and wand-shaped body, your odds of discovering well-hidden treasures are as good as they can be.
According to the most recent revision, the detector is completely waterproof (note the IP68 sign) and submerged underwater for up to 35 feet.
Audio, quiet vibration, and sound vibration are options for the device’s built-in alert system, which is quite adaptable. However, although the audio alarm is most effective for on-land hunts, the other two methodologies are well suited for underwater search and rescue missions.
To get this gadget up and running, all you have to do is push the built-in button once to turn on the detector and hold it down for two seconds to turn it off again. This helps you discover your goal fast and spend the least amount of time possible digging it from under the surface.
A 25 percent increase in sensitivity over previous underwater metal detectors of comparable caliber is claimed for this device.
The one-button operation method makes it simple to use in any water, regardless of the temperature.
It is not recommended for serious treasure hunting.
Suggestions for Using a Metal Detector While Underwater:
When you’re hunting under the surface, unseen hazards hide around every corner or quietly work against you. Make sure you’re prepared.
First, you need to ensure that you have the proper equipment, including more than simply an underwater detector. Sharp stones and pebbles, rubbish, glass, and coral may all cause serious damage to your feet and ankles.
The selection of the most appropriate sort of water boots for your hunting spot is critical. When you’re collecting stuff, having a mesh bag linked to your hip will make it easier to keep track of them and keep them secure. Using a sand sifter or sand scoop when beach searching will allow you to filter away the sand and other undesired minerals while still preserving the treasures you’ve discovered.
A sturdy, locking shaft on the detector can aid in maintaining balance and ensuring reliable operation while submerged. If your detector is particularly heavy and you intend to use it for land-based detecting as well, a chest strap or hip attachment may be necessary.
You should also take into account tidal movement. It is crucial to remain aware of when the water is moving out for your protection. Given that sand travels with the tide, it’s fair to expect that it will likewise shift treasures and make the seafloor more visible.
Summer is a fantastic time for metal detectorists because sunbathers and visitors are out and about, constantly losing their items. You will remain out and search for as long as possible because the weather is becoming warmer and the days are getting longer.
Swim gear is essential if you plan to go swimming underwater during the winter months to avoid hypothermia and other difficulties from occurring.
What to Look For When Purchasing an Underwater Metal Detector: Detailed Buying Guide
To make an informed decision about which underwater metal detector to purchase: it is recommended that you make a list of the qualities that will help you distinguish one model from another.
Exploring the sandy ocean floor with a bigger search coil enhances your chances of discovering hidden gems. Because of the larger diameter of the coil, it can cover a greater amount of ground in less time, resulting in less time spent searching for treasure.
This does not imply that smaller coils are less sensitive; rather, it indicates that selecting a detector with a small-sized coil will result in a substantially longer time to locate a significant number of metals beneath the surface of the water.
The Depth of the Water:
Even though underwater metal detectors are meant to function underwater, they are available in various depth capabilities. Submerging them to a depth greater than they were designed can cause part or all of their functionality.
If you want to go deep into the ocean’s depths in search of treasure, models with greater depth ratings will be the most beneficial to you in your endeavor.
Water and Audio Assistance:
Those who intend to use their underwater metal detector in seawater must get a device designed to withstand this sort of water.
It is possible that you may receive incorrect information and that your machine will be damaged if this does not occur. Those that provide extra underwater sound capabilities are better because they appear to deliver the most accurate results.
Waterproof vs Submersible:
Waterproofness is commonly used to refer to a search coil and shaft that are impervious to water. According to the manufacturer, these detectors are OK to use in shallow seas and at depths that do not jeopardize electrical components attached to and contained within the control box.
The headphones that come with these detectors are not waterproof and are designed for use on dry land. Extra caution should be exercised, such as not lifting the search coil over the control box when it is wet and avoiding splashing water about the control box during operation.
Submersible detectors, including the search coil, control module, earphones, and other accessories, maybe submerged. Submersible depths and protection, on the other hand, will differ among variants and makers.
The control box can sometimes be submerged, but the supplied headphones are not waterproof. Look for waterproof headphones, watertight headphone ports, and waterproof compartments in the items you are considering purchasing.
Type of Metal Detector:
Pulse Induction tech is used to create the finest undersea metal detector for salty beaches and scuba diving. Because of its deep-seeking circuitry, this sort of detector is extremely sensitive to rare metals and is particularly well suited for employment in difficult ground mineral settings.
If you use a PI detector, you will not have to dig through a lot of garbage to develop a significant number of riches since the short series of electrical pulses from the detector are not influenced by ground minerals or damp salt sand. This is because the PI circuits have a limited ability to discriminate.
VLF metal detectors are different underwater metal detectors that operate at extremely low frequencies (VLF).
This option functions in various frequency bands and is extremely sensitive to jewelry, artifacts, and coins, to name a few examples. Because of its superior discerning powers, it will disregard most rubbish things while detecting the majority of valuables.
On the other hand, a VLF detector is impacted by ground mineralization, making it a poor choice for usage in saltwater environments. If you intend to seek treasure in freshwater circumstances, the gadget will perform well for you.
Frequently Asked Questions:
Should ou buy pulse induction or vlf?
Pulse induction metal detectors, also known as various frequency detectors, are used to detect metal particles. When compared to a VLF detector, the precision of target identification is lowered or nonexistent. Less power usage than VLF detectors: necessitating more batteries and the replacement of batteries more frequently.
What is the price of an underwater metal detector?
The price varies greatly across models and, of course, between different brands of clothing. Underwater detectors from reputable manufacturers will cost between $500 and $700. There are several options available for under $1000 that will suffice for 10-20 feet. A deeper level of detail may be found in more costly models, and they will also feature complex user settings that allow for more customized user control under difficult situations.
Is it possible to use my underwater metal detector on dry land?
It is not against the law to use an undersea metal detector on the ground when looking over sand or soil, although it is discouraged. Because they function so effectively underwater, there’s no reason why they wouldn’t be able to function properly beneath the earth as well.
Can metal detectors be used in the water?
Yes! However, submersible metal detectors can operate in the water, but most waterproof metal detectors are not. Their construction differs from standard detectors in that they provide waterproof security for the whole detector, along with the control module and headphones.
Is it possible to locate diamonds with an underwater metal detector?
No, non-metal goods like diamonds, gems, and rubies will not be discovered with a metal detector. However, they may be able to direct you to indicator minerals. Following the route may lead you to a lava pipe that may hold diamonds and gold if you are lucky.
There is a plethora of alternatives available, making it difficult to identify the finest waterproof metal detector. We hope that our list and review have assisted you in narrowing down your search and making an informed choice on which one is the best fit for you and your needs! Best of luck with your hunt!
