A metal detector is an electronic device that uses magnetic fields to detect the presence of metal objects buried underground. A metal detector can be used to locate buried artifacts, coins, or other objects that may be of value.
Waterproof metal detectors, as the name implies, are metal detectors that are designed to be used underwater. These metal detectors are ideal for beachcombing, scuba diving, or any other activity that involves searching for objects in or near water.
While some waterproof metal detectors can be quite expensive, there are also many affordable options available on the market.
In this article, we will explore the benefits of using a waterproof metal detector, the different types of waterproof metal detectors available, and what to consider when purchasing a cheap metal detector.
Benefits of Waterproof Metal Detectors
One of the biggest advantages of using a waterproof metal detector is the ability to search for objects in water. This makes them ideal for beachcombing, scuba diving, or any other water-based activity where objects may have been lost or buried.
Waterproof metal detectors are also versatile and can be used on land as well as in water. In addition, they are designed to be durable and can withstand exposure to the elements.
Another benefit of waterproof metal detectors is that they can help to increase your chances of finding valuable objects. While some people may think that metal detecting is a hobby that is only pursued by treasure hunters, the reality is that many people enjoy finding lost items that may have sentimental value.
A waterproof metal detector can help to locate lost items such as rings, watches, and other valuables that may have been lost in or near the water.
Types of Waterproof Metal Detectors
There are several types of waterproof metal detectors available on the market. Each type has its own strengths and weaknesses, and choosing the right one will depend on your specific needs and preferences.
Pulse Induction Metal Detectors
Pulse induction metal detectors are designed to work in saltwater environments, making them ideal for beachcombing or scuba diving. They work by sending a high-voltage pulse into the ground, which creates a magnetic field that is used to detect metal objects. Pulse induction metal detectors are particularly effective at detecting metal objects at greater depths.
Very Low-Frequency Metal Detectors
Very low-frequency metal detectors are designed to work on both land and in water. They use two coils – one for transmitting the signal and one for receiving it. The signal is sent into the ground, and when it comes into contact with a metal object, it creates an electromagnetic field that is picked up by the receiver coil.
Very low-frequency metal detectors are particularly effective at detecting small, low-conductivity metals such as gold.
Multi-Frequency Metal Detectors
Multi-frequency metal detectors are designed to work on both land and in water, and they use multiple frequencies to detect metal objects. The advantage of using a multi-frequency metal detector is that it can detect a wider range of metals, including those that are less conductive. This makes them ideal for beachcombing or scuba diving, where a variety of metals may be present.
Factors to Consider when Purchasing a Cheap Metal Detector
While a cheap metal detector may not have all the features of a more expensive model, there are still several factors to consider when making your purchase.
Depth Rating
The depth rating of a metal detector refers to how deep it can detect metal objects. A cheap metal detector may not have as high of a depth rating as a more expensive model, but it should still be able to detect metal objects at a reasonable depth.
Sensitivity
The sensitivity of a metal detector refers to how well it can detect metal objects. A cheap metal detector may not be as sensitive as a more expensive model, but it should still be able to detect metal objects.
Discrimination
Discrimination refers to the ability of a metal detector to distinguish between different types of metal objects. A cheap metal detector may not have as advanced discrimination features as a more expensive model, but it should still be able to distinguish between common types of metals such as iron, aluminum, and copper.
Coil Size
The size of the coil on a metal detector can affect its sensitivity and depth detection. A larger coil will be able to detect objects at greater depths, but it may not be as sensitive as a smaller coil. A cheap metal detector may have a smaller coil, but it should still be able to detect metal objects at a reasonable depth.
Battery Life
The battery life of a metal detector is an important consideration, especially if you plan to use it for extended periods of time. A cheap metal detector may not have as long of a battery life as a more expensive model, but it should still be able to last for several hours of use.
Tips for Using a Cheap Metal Detector
Research the Area Beforehand
Before you begin using your cheap metal detector, it is important to research the area where you will be searching. Look for areas where people may have lost or buried items, such as parks, beaches, or old homesteads.
Properly Adjust the Settings
Each metal detector will have different settings for sensitivity, discrimination, and depth detection. It is important to properly adjust these settings for the specific environment and type of metal object you are searching for.
Practice with Your Detector
Before you head out on your search, it is a good idea to practice with your cheap metal detector. This will help you become more familiar with its settings and functions, and will help you to better understand how to interpret its signals.
Use Headphones
Using headphones while searching with your metal detector can help you to better hear the signals it emits. This can be especially important if you are searching in a noisy environment or if there is a lot of background noise.
Best Cheap Metal Detectors on the Market
There are many cheap metal detectors available on the market, but some of the best options include:
Bounty Hunter Tracker IV
The Bounty Hunter Tracker IV is a popular entry-level metal detector that is affordable and easy to use. It has a maximum depth detection of 8 inches and features a 6.7 kHz operating frequency.
Garrett Ace 200
The Garrett Ace 200 is another affordable option that is ideal for beginners. It features a 6.5 kHz operating frequency and has a maximum depth detection of 6 inches.
Fisher F22
The Fisher F22 is a mid-range metal detector that is still affordable for those on a budget. It has a maximum depth detection of 9 inches and features a 7.69 kHz operating frequency.
Conclusion
While a cheap metal detector may not have all the features of a more expensive model, it can still be a great tool for those who are just starting out with metal detecting. When purchasing a cheap metal detector, it is important to consider factors such as depth rating, sensitivity, discrimination, coil size, and battery life.
By properly adjusting the settings and using headphones while searching, you can increase your chances of finding valuable objects. With options like the Bounty Hunter Tracker IV, Garrett Ace 200, and Fisher F22, you can get started with metal detecting without breaking the bank.
