Search under water with a metal detector. Underwater search in difficult conditions. Hook system for underwater search

If you want to choose an underwater metal detector, then right now is the time when you need to choose a model, and getting ready for the summer. In this article, you will see short review to the most popular and lesser known models, which I will briefly describe.

There are two types of underwater metal detectors, this is an amphibious metal detector, with the ability to walk both underwater and on land. But, usually the maximum immersion depth of such metal detectors is up to 5 meters. And an underwater metal detector that has the ability to fully submerge in water, 20-30 meters, and is not afraid of salt water. While an amphibious metal detector can flicker into salt water.

Amphibians have an LCD screen, which does not allow them to deeply immerse the bushing, since there is a high probability that there will be damage from water pressure. And many devices drowned themselves in such a search. A new amphibian model appeared in 2012 Minelab CTX 3030, which I described in great detail.

While in a conventional underwater metal detector, you get all the information through headphones, and tuning is done through the rotary knobs.

Just a moment of attention !!! I have an article on our blog already - in it I give simple and clear advice to a beginner when choosing his first device.

The popularity of underwater search with a metal detector ( underwater metal detecting - English) is growing every year. Why? Because, unlike the usual terrestrial search, beaches, coastal areas and the bottom of seas and lakes will never become poorer. Each season, these places are replenished with new and new lost things and jewelry.

City beaches, coastal zone of seas and oceans, bottom soil of seas, lakes and rivers. Could these places be attractive to treasure hunters and underwater metal detectors? Agree, a stupid question. These places hide lost things, coins and jewelry, relics and artifacts in sunken ships, treasures and treasures under a layer of water and sand. The fact is indisputable.

How profitable is the hobby of underwater search and? ..

From unofficial sources of information, it is known that things, coins and jewelry worth about 25 million euros have been lost on the beaches of Italy alone over the past 10 years.

Agree that it is very easy to lose things like a ring, bracelet or chain in water. Try to take off these things yourself in the water, and everything will immediately become clear. Finding a lost item without a metal detector is almost impossible.

It allows professional divers and simple enthusiasts to find jewelry and treasures hidden under the water. Underwater exploration has paid handsome dividends from time to time. Treasure hunters prefer to keep secret the real number and value of the finds. Why? Because a profitable occupation always generates competition and envy.

Depth for underwater search

Thus, for an underwater search at a depth of 2-4m, you only need a mask and a snorkel; for a search at a depth of up to 20m, you will already need scuba gear and some preparation for diving.

Surveying ship wrecks will require diving to a depth of 75 m (there is a certain depth limit for underwater metal detectors). This requires special equipment and a fairly serious training of the diver.

This type of underwater search is considered the most adventurous and dangerous. However, there are treasure hunters who methodically and scrupulously search for shipwreck sites and scan wreck areas with underwater metal detectors.

The adventurousness of underwater search at shipwreck sites is that a treasure hunter can spend years researching and searching and finding nothing of value.

Or, on the contrary, you can find treasures by accident or after several dives. That's it! Nobody knows what will be revealed after the next storm or over time.

Beach Search is probably the only search option where almost anyone can find high-value items a short drive from their home. The most important thing is that you can regularly look for jewelry on the beach: after all, values ​​are also lost with enviable consistency.

The techniques used to find jewelry in fresh water are different from those used in salt water. V this manual we will dwell in detail on the search in fresh water.

Freshwater bodies are usually much smaller in size than salty ones, and there are fewer problem areas here too. There is definitely no soil mineralization. Often, the swimming places are limited by buoys, the very ones for which you "do not swim", so that the search area is conveniently limited by them. You can also lie on the beach and watch where people swim in order to examine the bottom with a metal detector early in the morning.

Metal detector

The two most important factors when choosing a metal detector for beach and spearfishing treasure are waterproofness elements containing electronic circuits, as well as the ability to adjust discrimination. The latter requirement is very important, since the discrimination setting helps to avoid unnecessary time and effort digging out hairpins, corks, aluminum cans, nails and other rubbish.

Salt water speeds up the corrosion process of small iron targets, so the debris disappears after a few months. In freshwater areas, a hairpin, lost in the 1930s, is still waiting for you to find it. True, for sure her appearance will give you a violent bout of frustration if your detector hasn’t rejected the target and you retrieved it.

Metal detectors VLF have established themselves as the best way for freshwater searchers because of their high sensitivity to jewelry and their ability to ignore debris. Multi-frequency detectors such as Minelab and Fisher also a good choice unless you plan on looking for jewelry at sea.

Experienced search engines often "upgrade" conventional metal detectors, making them waterproof, and search in water. But for beginners it is still better to take an underwater waterproof apparatus right away. "MDRegion" can offer such metal detectors from almost every major global brand. Choose from our online store.

Weight and balance may influence the final decision. Remember that a waterproof case and a heavy enough non-buoyant coil add weight to the instrument. For such models, sometimes you need to take care of the mount. Facilitates work if the control unit is removable and the coil is separate.

A very popular version of the metal detector with straight barbell. The S-bar is not comfortable underwater, but the straight line is balanced and easier to move. Therefore, the straight boom allows you to search more long time(the search engine does not get tired as much as with an S-shaped one.

The size search coil will depend on where you search. Large coils, as usual, cover large areas and give great depth detection, but in the water they move slowly, moreover, in trashy areas they can miss standing targets. Small coils also have their pros and cons.

Accessories

After choosing a metal detector, you will need to decide on the accessories. Your arsenal may include: digging tools, mesh bag or lost bag, sand sifter. If you are planning to wander along the shore, then buy a fishing overalls with boots, and for an underwater search you will need either a swimming mask with a snorkel or scuba gear.

When searching in dry sand, a scoop will be needed. It can be either metal or plastic. Plastic is convenient to bring directly to the metal detector coil and check for a target.

A sand sifter with a long handle is required for searching in shallow water. This is a special device like a metal net.

You can capture on searches search magnet... It will help clean up rusty debris.

Search location

You are now ready. The question is where to go to look. Well, the first thing that comes to mind is the municipal beaches and, in general, all the famous beaches in the city / town. Then there are the private beaches. Then the quarries for the extraction of sand - here, too, people love to swim.

You can also ask all your friends where they prefer to swim and if they know any "wild" or abandoned beaches.

Here is a rough list of the areas on the beach to look for first:

• Places where mothers splash with their children ("paddling pool", shallow water). It is known that ladies love to use sunblock or sunblock. In combination with water, these creams do their "dirty" job - rings and bracelets slide off.
• Places where people "walk". Those who cannot swim usually enter the water up to their waist.
• Dry sand. It is clear that sometimes when unfolding and folding blankets, towels and blankets, the rings catch on and "sink" in the sand.

After you have established discrimination, do not increase its level. Remember that plugs give the same signal as jewelry.

Outcome

If you want to rejoice in successful finds, then searching in fresh water and on the beach is just for you. This exciting hobby can be enjoyed anywhere in the country. Of course, with the right equipment from MDRegion.

Search for coins, jewelry and artifacts underwater - effective method increase your chances of finding more goals. Also, combining search on land and in water is especially pleasant in summer, when you have the opportunity not only to do your favorite hobby, but also to plunge or swim.

Underwater search is different from normal detecting and can be more difficult than you thought. You also need to buy a waterproof metal detector. When you have the right detector and follow these rules, you are guaranteed interesting finds.

1. Plan ahead.

It is very important to properly plan your search so as not to waste your time and energy. The first thing to consider is the time of year when you go to dig. It is logical that you need to look for something in the water when it has already warmed up. Of course, if you have a reliable wetsuit, you can search during the cold season as well. Consider also weather reports. Searching underwater in a rainstorm or hurricane is not safe.

2. Choose where to search.

To increase your chances of making good finds, you need to figure out where the most popular areas on the beach are. This also applies to underwater search. Usually, most of the finds are where people "walk on water", that is, the depth where they do not swim yet. Also good for finding the docks of pleasure boats, catamarans and the like. If the beach is touristy, it is worth checking out the areas around water attractions or water sports facilities (diving towers).

3. Learn underwater search techniques.

When you are just starting out, you need to become familiar with the methods and techniques for instrumental search. You can, for example, follow a line along the coast, moving at meter intervals. Check all natural depressions and pits in the bottom as they may contain anything of value. Also, underwater search engines sometimes use special scoops - narrow so as not to pick up mud, and if they are looking shallowly, then scuba (sieve on a stick) and floating rafts with an improvised sieve, which help to separate targets from dirt.

4. Search during the daytime.

Instrumental search in water is already quite difficult. At night, everything becomes much more complicated, since the visibility under water is much worse than in the air, and even strong flashlights do not always help well. So if you are aiming for an underwater search, then start in the early morning or when the day is already in full swing.

5. It is not necessary to practice underwater diving.

Before starting an underwater treasure hunt, many recommend taking a few scuba diving lessons. But for this you must have special equipment, for the purchase of which you do not always have the money. However, judging by the experience of many search engines, it is not necessary to take diving lessons. Most of the targets are hidden at a depth of 1-1.5 meters, and in order to find them, you do not need to buy scuba gear.

Underwater treasure hunt: exploring new horizons

Hello dear readers. I have not posted reports on treasure searches for a long time, and I explain why. I went to the sea to rest, and also mastered new horizons of treasure hunting. In general, there was no time for forest trips, nevertheless, he expanded the aura of his knowledge and practical experience in such a matter as ... underwater search! I tell you in detail ... your YouTube diary, I made friends with many comrades and like-minded people ... Somehow I was intrigued by one friend who looking for coins, artifacts and relics under the water! After contacting him, I told him that I was intrigued by the underwater search, and would not mind trying it in practice. Our conversation dragged on for a couple of hours. I asked a lot: what is the best way to start, how to make your device underwater, what to wear, how to look underwater ... pretty tired of the interlocutor with answers.

Underwater search is also carried out underwater with a metal detector.

How to start an underwater search

An underwater search begins with an audit of the main equipment - a metal detector. The first thing I had to do was send my E-Track for an upgrade, which took as long as two weeks. Much was altered, only the "brains" remained, which were placed in a box that does not allow moisture to pass through. We changed the battery box, and replaced the native battery with three AA batteries. To search underwater, I had to buy an 8-inch coil, which will make it easier to find the target.

"Underwater E-Track" searches underwater

I also had to remove mine and change them to wired underwater... All cable entries to the unit have been redesigned so that no water can enter. In turn, in order to search outside the water, two rods were made to the upper shaft: a short one for searching underwater, and a long one for a standard one. . I also had to send a standard coil to remake the plug.

From wireless headphone had to refuse

Hook system for underwater search

While the instrument was being redesigned, I had to start assembling the Hook system for underwater search. For this I bought: 3 food pipes with a diameter of 150 mm. two meters each, and 4 knees, so that in the end result I got a rectangle 120x70 cm. I planted all the pipe joints on moisture-resistant glue - sealant, and glued this whole structure on a sheet of foam plastic, 5 cm thick, and with a density of 30. When the glue dried up, I got an air receiver.

DIY Hook system

On one side of the tube, I drilled two 13mm holes so that the fittings used in tubeless car wheels could be inserted, and another hole on the other side. Also, on four sides, I attached small rings with puffs so that a rope or various devices could be attached to them.

Inside the structure, I bought a sealed food box for 10 liters, in order to accommodate a low pressure compressor of 105 l / min, and a helium accumulator for 33 Amps. After talking with a friend and asking for advice, I bought two batteries and Charger to them. I connected the compressor and the receiver with a food-grade flexible tube, at the outlet from the receiver I attached a five-meter-long tube, at the end of which I attached a lung tube that scuba divers use.

Underwater search equipment

To be in the water for several hours and dive to a depth of 4 - 5 meters, I had to buy wet wetsuit 7 + 7, with the expectation that I will dive in the fall and spring. To swim normally underwater, you need loading, so I bought belt with weights of 14 kg... To see well and swim normally, I had to buy mask and fins.

When testing the system, I encountered such a problem as a hard bottom cover, for this I had to buy a garden shovel. Also, in order to explore the coastline, I purchased for a beach search.

The first finds under water

It took me two (2) months to collect all the gear! Much had to be altered, improved, learned, learned and learned. And, having learned to confidently swim underwater and have tested all systems and components in every possible way, I decide to make the first underwater searches. I choose the place to look for the Southern Bug river, or rather, the old beach, where life once raged.

The place of my first underwater searches was the Southern Bug River

One morning, I load all the equipment into the car and go to the search site. Having gone to the beach, I realized that local shepherds were already waiting for me. But, it doesn't matter, after answering all their questions, what I want to do, I unload everything from the car and get ready for the underwater search.

I just went into the water and turned on the device, and the whole earth beeps, where I don't put the device everywhere the signal! So many ... beer caps and cans lids with jars, I did not even lift in places where people used to celebrate the May holidays 🙂 For several decades, the bottom of this beach is simply covered with metal products. I think this is bad, both for the ecosystem and for the people themselves.

Along with this rubbish, coins, late tips and modern walkers are also common. I don't want to describe each of these goals, since there were a lot of them. Also, in a few hours of underwater search, I became the owner of 300 grams of cargo, from different types fishing tackle.

Loads from fishing tackle - how without it under water?

But, most importantly, for all my labors, Grandpa Neptune opened to me ... gold earring and chain... At the end of the day, I also managed to raise the underwater watch by Casio.

In addition to the finds, there is something to rejoice under the water: the underwater element is very beautiful, albeit littered with. Several times fish swam up to me, wondering what I was looking for here and who I was. I didn’t tell them, but having dived a lot and planted two batteries, I stopped my water campaign. As always, I upload my findings and take pictures.

The final finds of the day in one photo

I think that my first underwater search was a success, I also discovered another type of rest and good time, finally making my metal detector friends with water! Satisfied with my first dive with MD under water, I suggest you dive with me into the abyss of water ... Watch my video report:
