What Is The Best Metal Detector for Freshwater?
Many beaches are hunted with metal detectors every day, but the shoreline of freshwater areas is not. Because of that, you may have more luck at a lake, creek, stream or river than you would at a beach. You can find a lot of jewelry and coins in freshwater areas.
Since freshwater won’t have the interference from the salt that beaches do, you have greater flexibility in picking a freshwater machine. You do, however, want to make sure it’s waterproof and sturdy. If you only plan to go ankle deep in water, a waterproof coil may be enough, but going this route always comes with risks. A dropped machine that is not waterproof can result in a dead machine and lost investment. Because of this risk, we never recommend using a machine that is not waterproof anywhere near water.
You may also want to consider a coil cover, since you may be scraping your detector along rocks and more rugged terrain.
Thinking about diversifying your scuba diving experience by adding an element of fun? Waterproof and underwater metal detectors are able to provide you with just that.
Using electromagnetism, waterproof and underwater metal detectors will quickly alert you to metal objects under the surface both on land or in the water. Regardless of whether you invest in a pulse or a very-low-frequency detector, you can expect it to give you a memorable experience .
Types of Underwater Metal Detectors
Pulse Induction Metal Detectors transmit a series of quick electronic pulses in to the ground. These electronic currents are not affected by wet salt sand and ground minerals, but they are highly sensitive to precious metals. A Pulse detector is best for salt water beaches and diving. The Pulse circuit is very deep seeking, and is great for tough ground mineral conditions. The PI circuit features limited discrimination capabilities, so you will need to dig more trash items if you want to locate the maximum number of precious objects. Here is a list of links to the best Pulse Induction under water metal detectors. You will also find reviews on each model at the links below:
Very Low Frequency (VLF) Metal Detectors typically operate in the 3 to 30 kHz frequency range and are quite sensitive to coins, relics, and jewelry. The VLF detectors have the capability of discriminating out junk targets while still accepting good items. Unlike the PI circuitry, the VLF circuit is affected by ground mineralization. Most VLF detectors have a sensitivity adjustment and sometimes a ground balance control. By adjusting the sensitivity or ground balance adjustment control, you can minimize signals caused by ground minerals. Here is a list of links to the Best VLF underwater metal detectors. You will also find an under water metal detector review on each model at the links below:
Although most underwater metal detectors have the same functionality, they differ in the following ways:
- The size of the search coil (which is closely linked to your chances of finding the sought-after treasure)
- The type (pulse induction (PI) detection vs. very low frequency (VLF) detection)
- The depth of water the device can safely be submerged under without stopping to work
- The availability of additional underwater audio support
To guide you in the right direction, we gathered a list of the best underwater metal detectors whose pros outweigh their cons. We suggest you carefully review the items listed below in order to find the best match for your needs.
Do you want to go metal detecting and scuba diving? The Minelab Vanquish is for you. This detector is waterproof up to 200 feet, but it’s also effective on land. It features 17 different frequencies to help you find more coins, rings and relics buried deep down.
One of the nifty features is that this detector emits a different tone for every frequency. The tone for gold, for example, will sound different than the tone for silver.
Nokta Makro Anfibio Multi
The Nokta Makro Anfibio Multi is waterproof up to 16 feet. It’s rugged, durable and reliable and the menu features a simple design that is very easy to use. Multiple search tones make this great for finding a wide variety of objects. It’s very stable on dry or wet sand, meaning it isn’t picking up signals for “junk.”
The Anfibio includes a vibration mode, which is specific to this manufacturer for the hearing impaired. This machine offers nine search modes, including a deep mode and a cache mode. It also features an adjustable armrest, which most other machines don’t have.
Minelab Equinox 800
The Minelab Equinox 800 can be used on every type of ground and is great for coins, relics, and gold. The gold mode is great for gold nuggets. This detector has eight custom search profiles and is fully submersible up to 10-feet. It’s lightweight, and holds up well in any environment, including around saltwater. The LCD screen features target numbers that allow you to know your target ID at a glance.
This machine set the metal detecting world on its ear when it was introduced to the public. The only machine with true simultaneous frequency technology that Minelab refers to as Multi IQ, this machine is revolutionary and is changing the game in metal detecting. It has the fastest recovery speed and target separation of any machine on the market today. It has been a perennial bestseller since its introduction and created massive waiting lists and production backlogs when initially introduced.
What accessories will I need to be successful?
Below are our suggestions for the basic equipment that every well outfitted underwater treasure hunter should have. You can always spend more money on additional items later, but these are the basics of what you should have. Headphones will let you hear the oldest, deepest targets & block external noises.
All underwater detector come standard with a set of waterproof headphones. A Carry Bag is an excellent way to protect your new detector and makes transporting easy. While hunting along the beach you will want a Trowel. You will also want one or more Metal Detector Sand Scoops. A beach sand sifter scoop will greatly speed up your recovery.
