Metal detectors for underwater treasure hunting

People have different hobbies. There are those who are inclined towards finding antique valuables and there are those who collect items for the sake of it. If you are one of the people who enjoy hunting for metallic stuff, you will be related to finding out that there is a wide variety of metal detectors out there that will help you achieve your goal.


So, what is a metal detector?

A metal detector is what it sounds like: an instrument used for detecting metallic objects, and if your hobby is finding coins and other stuff, it helps you find these items no matter how deeply they may be buried, depending on the type of metal detectors that you have.

A metal detector works by producing magnetic fields which, when in line with or near a metallic object, produce either a sound or cause the fluctuation of a needle on an oscilloscope.

Getting the best metal detector

When looking for a metal detector, you will quickly realize that there are lots of different models in the market. Most of the older models have a pole while some of the newer models can be attached to a belt and hang around your hip. When getting the metal detectors that hang around your hip, you may want to consider the weight of the machine especially if you are looking to use the device for extended periods of time. Regarding the accuracy of the model, you may be looking to buy: different models offer a range of precision in addition to how deeply they look for objects. Be sure to have a good look around to find the best metal detector especially if you are looking to go hunting for objects in places such as the beach.

The second thing you might want to consider is the output of the metal detector. We have mentioned that some metal detectors produce a pulse while others use an oscilloscope to indicate that they have located an object. The beeping and pulsing sounds of the metal detector may be annoying to some people, so if you fit into this category, it would be best to get the needle-based metal detectors.

The third thing to look it is how the metal detector works. Different metal detectors work differently and thus may be seen to be better than others. For example, some metal detector models use a bigger and better coil. These help you to locate objects that are located a bit more deeply.

If you are looking a metal detector that will help you locate smaller objects or looking in areas that have a lot of objects lying close together, it is advised that you get a detector with a smaller coil.

In addition, if you think that you are going to be looking for objects in grounds that have some minerals in them, it is always a good idea to go for metal detectors that have ground balance control or a multi-frequency style indicator.

A lot of people who shop for metal detectors do so to use the detectors to do underwater exploration. The best metal detectors for these activities include pulse induction metal detectors and very low-frequency metal detectors.


The difference?

Pulse induction metal detectors work by emitting a series of pulses. These pulses are not affected by water or wet sand. They are best suited for those looking for precious metals because they are highly sensitive to these types of materials. The pulse induction metal detectors are also better suited for salty water.

These types of metal detectors are very deep-seeking and therefore work very well in areas that have hard ground mineral conditions. The one caveat about these metal detectors is that they have very low differentiation abilities meaning that you may have to dig up a lot of useless items before striking gold, literally and figuratively.

On the other hand, we have very low-frequency metal detectors. These works in the 3-30 MHZ range and are best suited for finding coins, jewelry, and relics. In contrast to the pulse induction detectors, they have high discrimination and differentiation abilities and are affected by ground mineralization.

Very low-frequency metal detectors do come with ground balance control and sensitivity adjustments. By making use of these two types of adjustments, it is possible to minimize false positives that are caused by ground minerals.

Interesting items that you can find using your metal detector.


One of the most touted reasons of why people buy metal detectors is finding precious coins and antiques. These can go for a pretty penny, pun intended, making them precious. Finding coins can be challenging which makes searching for places where coins are found using a search engine is usually the best way to go.

A lot of people go hunting for items on the beach and most of the items they do find, as mentioned, are coins and jewelry. The jewelry could come in handy when you need some cash making this hobby still valuable.


Is coin hunting dying?

Coin hunting, as mentioned, is one of the biggest reasons why people buy metal detectors. It has been a hobby for a lot of people for a long time but some enthusiasts report that it is a dying hobby. Why is this, you ask? Well, if you look at what people have found over the years hunting for coins and the efforts put into finding these items, the balance is not quite right: the effort does not equal the payout.

That said, there are more and more coin hunting sites being discovered all over the world, and this is one of the things keeping this old hobby alive.


In conclusion

There are lots of metal detectors in the market. In selecting one, all you have to do is gauge your needs and choose the one that you can carry, that can work where you want it to, be it on the beach or deep inside the ocean, and one that discriminates items so that you do not spend most of your time hunting for objects that have no value.
