Buyer’s Guide for the Highest-Rated Waterproof Metal Detector

This brief guide is designed to acquaint you with waterproof metal detectors, especially if you are a beginner. We have discussed a few tips on purchasing the best detectors on the market according to your specific requirements.

How to Choose the Right Waterproof Metal Detector?

Since there are multitudes of options available in the market, it is important to have a little background knowledge so you can make an informed decision. Here are a few considerations you should keep in mind when browsing different brands.

Detector sensitivity

The sensitivity of the metal detector is probably one of the most important considerations because it can define the tool’s ability to detect different kinds of metals. Several factors, like appliances and soil mineralization, can impact the signal, so it is important to purchase one with high sensitivity, even if you want one for non-professional use. Also, buying a detector with adjustable sensitivity is ideal so that you can adjust it according to the ground type and environment.

Search coil

The quality of the search coil is also an important feature because it works as a magnetic transmitter as well as a receiver. Generally, a larger coil is better for high frequency and sensitivity because it can cover more ground. However, you need to be mindful of bad falsing and sometimes missed targets as well. Also, if you plan to use your detector underwater, make sure that the coil is submersible.

Battery life

The battery life of your metal detector should be at least 10 hours. However, this is the minimum and is usually considered ideal for beginners. Some advanced and professional metal detectors can provide a battery life of up to 75 hours. Since such tools can be expensive, they are ideal for professionals. It is also recommended to remove the battery if you plan to store your detector for a prolonged period of time. If you are going on a long expedition, keep a few extra batteries at hand just in case.

Difference Between Saltwater and Freshwater Hunting

Even though waterproof metal detectors are ideal for both saltwater and freshwater hunting, you need to make sure that you are purchasing the right tool for your specific requirement. When hunting near the beach or underwater, there is likely to be a lot of saltwater mineralization around. This can interfere with the signal, which is why it is necessary to invest in a multivariable metal detector. These tools allow you to adjust the frequency so that you can detect desirable items more accurately.

Freshwater hunting does not require very advanced tools because the level of mineralization around these waters is very low. As long as your detector is waterproof and provides sufficient detection sensitivity, you are good to go. It is essential to keep the purpose in mind when buying a waterproof metal detector.

People Also Asked

Do waterproof metal detectors work on land?

Yes, waterproof metal detectors can be used on land. However, these tools tend to be a little heavier than those that are not waterproof, so if you only plan to use them on land, look for one that is designed for that specific purpose.  

Can a waterproof metal detector detect diamonds?

No, metal detectors are only designed to detect metals, so they will not pick up the presence of diamonds or other gems. However, if the diamond you are looking for is attached to a metal chain or ring, a metal detector will be able to pinpoint it. 

What is the ideal frequency of waterproof metal detectors?

The ideal frequency for somewhat accurate metal detection ranges from about 5Hz to 15Hz. Professional detectors have higher frequencies, but these are generally expensive. Just make sure the detector you buy comes with an adjustable frequency.
