Hey there and welcome to my post where we will check out my three best underwater metal detectors to explore the waterways with this year. If you are looking to add some more fun to your fishing, swimming or scuba diving adventures, what better way to do it than using underwater metal detectors?
I mean you just never know what treasures are hidden down there in the deep – or shallows if you are swimming – haha. And as this is something that you may not be totally familiar with, I have had a good look around and come up with three decent options for you check out below.
Let’s have a look…
My three recommended underwater metal detectors
I will review these in more detail below however if you just want to get moving without all the carry-on, my recommended products are listed here for your convenience:
What are underwater metal detectors?
Underwater metal detectors are specialized instruments that can detect metallic objects submerged in bodies of water or even those that the sand has covered along seashores. In essence they are exactly the same as metal detectors that are used on land, except they are a shaped differently and water proof.
When used in the water though, you should be aware that you do need to be down near the bottom for it to work meaning you will be swimming, snorkeling or scuba diving when looking for treasure. They may also be useful for your magnet fishing needs as well.
What should you be looking for?
The following factors should be considered as you hunt around for a good underwater metal detector for your fossicking adventures.
- Construction material
- Type
- Waterproof rating
- Search coil
- Audio support
- Additions
Construction material
As you shop for underwater metal detectors, you will probably come across products made from PVC or stainless steel. These materials are suitable for underwater metal detectors since PVC and stainless steel can withstand corrosion brought by submerging in the deepest waters.
However, stainless steel is more durable than PVC, making the former a better choice. Whatever construction material you prefer for your underwater metal detector however, just be sure that the instrument is appropriately sealed and has quality assurance markings to ensure it is effective underwater.
Type
Underwater metal detectors rely on two types of technology being pulse induction detection and very low frequency detection. These are outlined as follows:
- Pulse induction detection – Pulse induction metal detectors use a single coil as both the transmitter and receiver, making it easier to search in regions with high-ground mineralization. It emits electrical pulses into the earth, creating an electromagnetic field. They are extremely sensitive and will overlook minerals and salt in the water. Furthermore, the electromagnetic pulse penetrates deeper into the earth, boosting the likelihood of discovery.
- Very low frequency detection – These instruments generate a steady magnetic field that is generated by one coil and pushed into the earth by another. A secondary coil catches up with the magnetic field once it bounces back. When utilized in harsh conditions, most VLF devices nowadays are adjustable allowing you to fine-tune them to function in your surroundings.
Waterproof rating
As previously stated, depth and water protection are critical regarding underwater metal detecting mainly as the strain of deeper waters can effect waterproofing measures. To be sure, examine their IP ratings to determine how waterproof they are. In general terms, the deeper a metal detector can penetrate, the higher the IP rating the are.
Some will also record a depth rating on their products as well – this will also guide you to waterproofing capabilities too.
Search coil
When selecting the best metal detector, you must strike a balance between mobility and coverage. A broader search coil will allow you to scan broad regions fast. However, you will have to cope with the inconvenience of carrying a large gadget when underwater. On the other hand, metal detectors with small-size coils have a restricted scope and may cause you to overlook a metallic item.
Audio support
Most detectors emit an auditory signal to notify you of the presence of metal nearby whereas others will simply just pulse. The most basic audio support is a simple beeping sound and although useful, it does not convey nearly as much information as a ground-balanced audio system.
These devices generate high-pitched noise, which is proportional to the intensity of the electromagnetic field. Thus, a louder or higher-pitched tone indicates that the item is close.
Additions
Other potential additions include:
- Wrist strap: This item is useful for keeping the instrument within your reach and from slipping from your hands.
- Control interface: This refers to a metal detector that offers adjustable user settings to fine-tune the equipment better.
- Battery: Most use a replaceable battery whilst others offer rechargeable options.
- Warranty: Products with warranty offer buyers confidence that their items are new and in working condition.
FAQ
Can underwater metal detectors be used on land?
Absolutely, in fact many use them on the beach and lake’s edge as well as in the water. Whilst smaller varieties do not have the range of land based detectors, they will definitely work just as well.
Do underwater metal detectors work?
Yes they do! As long as it is waterproof and you are not using it at depths outside their range, they will detect metal very well.
My three recommendations broken down
So based on the information above and my own experience, I recommend the following options:
1. PudiBe Pinpoint Metal Detector
This handheld underwater metal detector is a pinpointer type making it very straightforward to use. It can be used both above and below the water for simple identification of buried objects. See its specifications below:
- Brand: PudiBe
- Construction material: PVC
- Type: Pulse Induction Detection
- Water proof rating: Not stated
- Depth capacity: 10 feet
- Weight: 0.56 pounds
- Dimensions: 9 x 1.5 x 0.9 inches
Other inclusions:
- Flashlight
- LED indicator
- Sensitivity modes
- 48 hour battery life
- 12-month warranty
Why have I chosen it?
My first underwater metal detector is easy to use due to its lightweight design with one-button operation that makes it excellent for newbies or those who just want something simple. It also works effectively due to its accurate placement and high-sensitivity 360-degree detection.
There are audio and vibrator alerts to choose from, so you have settings to use according to your preference and the built-in flashlight can assist you in seeing at night. With a depth limit of 10 feet, this item allows you to search for any metallic things beneath the waters as well.
2. SAKOBS Waterproof Metal Detector
My second underwater metal detector option allows for use at depths of 20 to 60 feet and is equipped with a high-sensitivity sensor that enables you to locate metallic items hidden underneath. See its specifications below:
- Brand: SAKOBS
- Construction material: PVC
- Type: Pulse Induction Detection
- Waterproof rating: IP68
- Depth capacity: 20 to 60 feet
- Weight: 0.34 pounds
- Dimensions: 11.06 x 2.95 x 2.8 inches
Other inclusions:
- Holster
- Safety clip
- Led indicator light
- Rechargeable battery
- Three alert modes (vibration, sound, sound and vibration)
Why have I chosen it?
My second underwater metal detector is a basic pinpointer with numerous settings to better adapt to your situation. It comes with vibration, audio and vibration and audio modes for alert via single button for one-touch activation. Aside from being simple to operate, the gadget is just 11 inches long, weighing just 0.34 pounds making it highly portable. And because the gadget can be entirely submerged up to 60 feet, you can explore deeper into lakes, rivers or the ocean with ease.
3. Wedigout Fully Waterproof Pin Pointer Metal Detector
My final underwater metal detector provides for great quality with vibration and liquid crystal display (LCD) detection. Its basic structure makes it easy to operate while underwater up to 100 feet below the surface. See its specifications below:
- Brand: Wedigout
- Construction material: Stainless steel
- Type: Pulse Induction Detection

Why have I chosen this?
The detector can detect to a depth of 100 feet and uses pulse induction (Pi) technology, which means there is no interference between your target and the metal detector. Its performance is unaffected by whether you use it for dirt, sand, seawater, or solid coral.
Furthermore, the device lacks sophisticated buttons, making it incredibly simple to operate when underwater and may be turned on and off with a simple hand movement. This scuba diving metal detector also has a vibration LCD detection that signals the user when a metallic item is nearby.
