Hello friends. How he does it? He sees plastic pipes and wood and all kinds of metals. How the GD216 metal detector from GVDA works, see the video.

Today we will conduct a series of tests through a 10 mm thick Plexiglas sheet.
We glue the device with our own hands on double-sided tape directly to the plexiglass and first check in what modes what materials the metal detector will see.
Let's turn it on and start with the wood search mode. Let's see how he does it. He sees plastic pipes and wood and all kinds of metals. The closer the wood is to the center of the sensor, the higher the percentage value. Once in the very center, a symbol in the form of a cross is displayed on the screen. Agree. The device sees wood quite well and quite accurately.
A smartphone emits electromagnetic waves. Therefore, the GD216 metal detector sees it in all modes.
A copper two-wire wire also sees in the wood search mode, but the fact that it is really a wire and it understands under voltage when switching from a deeper to a more accurate mode.
I talked about how to change modes, calibrate, lower sensitivity, etc. in the first video. If the metal detector is switched to the hidden wiring search mode, then he immediately realized that the wire was live.
Wood in the wiring search mode can be said not to see.
In the metal search mode, it does not react to wood at all, because it works like a metal detector.
In the mode of searching for wood, the device reacts to metal, as well as to wood. If the device is switched to the metal search mode. That signal quality improves. In addition to the percentage scale, the device began to show the distance to the metal in centimeters. 1 centimeter is the depth, in our case the thickness of the plexiglass. The horseshoe symbol indicates that the metal he noticed is magnetic.
In the hidden wiring search mode, the metal detector practically does not react to metal.
As you can see, there is no universal mode for all cases. That is why to search for electrical wiring, select the electrical wiring mode, to search for metal, the metal mode, and to search for wood and other materials, select the wood search mode.
Other materials include plastic. Here we will check. Can a metal detector see plastic pipes?
Polypropylene water pipe - the device does not react. Sewer PVC pipe - also does not react. The instructions say that he sees plastic pipes and wood and any metals. Maybe it reacts to water. Let's check in the metal search mode. There is water in the hose, but the device does not react.
Let's switch the metal detector to the mode of searching for wood, and lo and behold! The device sees a hose with water.
In addition, it does it with good accuracy.
Especially for this experiment, I soldered one edge of the sewer PVC pipe.
Let's fill it with water. And again a miracle! The pipe became visible. The GD216 metal detector reacts quite accurately.
So, dear friends, water pipes and heating pipes filled with water can be easily found by the GD216 metal detector in walls, floors and ceilings. Since the metal detector reacts not to plastic but to water, it will also react to other objects inside walls with higher humidity. The metal detector in terms of price-quality ratio turned out to be really sensible and will be indispensable for those involved in repairs. This device can be safely recommended. At the end of the video, we found out who will get the GD216 metal detector from GVDA.
In the next video, we will play a chic digital microscope.

Now you know how the GD216 metal detector works. And how he sees plastic pipes and wood and any metals
