The real hams are not those citizens who want to save their money on the purchase of new equipment, but those who really want to bring all the existing parameters of a particular unit to the maximum performance. This statement applies to those who plan to make their own underwater metal detector. This option is only relevant if the master has the necessary skills. The result of the manipulations will depend on how well the quality materials were prepared in advance.
Description
underwater metal detector to build with their own hands is not only easy, but also financially beneficial. With the help of the finished product can find a variety of items at the bottom of the river, sea or lake. The unit functions perfectly even in conditions of poor visibility and loud noise. Experts highlight the following features of the metal detector:
- The product advantageously differs from the classical unit length under water. Some experts prefer to go up to the throat with a metal detector, because of which it is necessary to take into account the optimal immersion depth of the device. It is necessary to foresee all the nuances.
- To make a high-quality underwater metal detector with your own hands, you need to configure the product to search for non-ferrous metals.
- Accurate recognition of tiny objects: rings, earrings, chains. These products are the main prey for underwater seekers.
These three criteria must be taken into account master during assembly equipment.
The main nuances
To make an underwater metal detector with your own hands, you need to prepare a PETV wire 0.5 mm thick in advance. The master should get 25 turns. You can experiment with wire and coil shape. For a classic product, you need 25 meters of PETV. To build a control unit and a rod, you need to use a tube made of stainless steel or plastic. This requirement must be observed, as other materials under water will be negatively affected by corrosion. If the master builds a stainless steel and plastic structure, the finished product will favorably differ from all analogues in a long service life. The main frame should not be too light, otherwise it will constantly pop up. In order to make a self-made underwater metal detector reliable and comfortable in operation, it must cope with the negative effects of salt sea water.
Necessary tools
Make an underwater metal detector with your hands can be just a few hours, if you comply with all the recommendations of experts. A universal unit can be manufactured if the following tools are prepared:
- electrical tape;
- soldering iron and solder;
- PCB;
- sharp knife and scissors;
- PETV wires with parameters of 0.5 mm;
- basic set of electronic components;
- silicone sealant.
detailed instructions
It’s not so difficult to build an underwater metal detector with your own hands, the main thing is to start with the preparation of the printed circuit board. After that, all the necessary electronic elements are carefully installed on it. Details are best soldered. The wizard will have to connect a power source. It should be a powerful rechargeable battery, not a regular battery. The prepared board with the power supply is installed in a sealed container. If necessary, you need to bring LED bulbs to the surface. All joints must be treated with silicone sealant. The capacity is fixed to a pre-assembled rod. It is necessary to qualitatively wind the search coil. For these purposes, a 3-liter jar is ideal. The enclosure must be plastic. Coiled wire neatly poured silicone sealant. It only remains to solder the leads from the coil to the stranded wire.
Maximum tightness
Experts recommend to fill in all the gaps with silicone sealant. For the control unit and the coil, classic polypropylene pipes of suitable diameter can be used. Build a high-quality rod from an old fishing rod and reliable adapters. For the box of the power supply, you can safely use the tube from the sealant. At the final stage of the wizard will put the waterproof connector ports. Due to this, it will be possible to connect underwater headphones for the metal detector.
With your own hands you can build many interesting and high-quality products. You just need to follow the classic pattern. With the finished metal detector, you can dive to great depths. The unit must have compensated salts, as well as comfortable indication. The use of a classic display in this industry is unjustified. It is best to make the device as an amphibian or underwater detectors. Thanks to this, it will be possible to recognize valuable metal products on the ground and under the water column.
