I made a simple one using a two transistor oscillator with a 5 inch coil of 3/8 inch copper on the head. And in the box was another oscillator and mixer to the phones. The coax fed power to the head, and brought the signal back up to the head. It is a very simple looking device, but it worked fairly well. It had a flaw however as it seemed to be mainly for iron and especially for aluminum. Gold gave a weak and soft response.
Thats amazing : I want to make one to find coins . Its overwhelming to see all the expensive metal detectors out there . I'm an average joe that has some electronics background and I've always thought there has to be a way to metal detect without buying all the expensive bells and whistles for coin hunting
I realize that this is an older video, but if you are still doing these kind of projects, you might want to try building the Russian PIRAT pulse induction detector. Mine detects coins at 8 to 9 inches, and bigger stuff much deeper. It's not good for trashy areas though. Just the nature of the beast. I may have to see about building one of these as well, if I can get more depth out of it. Good video. Rekindled my interest.
Looks like it would be a fun project. Nice work! Do you know how much it would cost to make? Thank you for explaining the circuit so well and clear. That's seams to be somewhat rare and will definitely help me as I take on learning electronics.

10 - 20 yrs ago I'm a junkie of talking electronics.. lol..! They created lots of great quality electronic hobby stuffs.. I did lots of stuffs especially the whole series of fm bug for my kids through fm radio as receiver.. 😁😁😁.. its really fun for them.. also small simple robots like Harbi mouse of USA made.. kids love them.. So, kindly tell me what's the depth range for this metal detector.? God knows, I might wanna try this too at this age.. hihihi.. my hands & fingers are still steady to solder.. 🤭🤭🤭 Thank you for the excellent video.. especially when its schematics are from Talking Electronics..! You'll never go wrong.. ❤️❤️❤️💝💝💝👍👍👍
I like Minelab metal detectors. If you're looking for deep items, then you need to buy a larger search coil for use with the metal detector. Larger coils have trouble detecting very small objects, but have no problem finding items larger than a pencil eraser.
i hope i can build that so that i try to find gold or silver, thanks to you, by the way im in the phillipines, hard to get that items, but thank u, have a good day
Echoing Uncle Doug's comment... but I am interested in knowing/understanding (to a small degree), what is it that Minelab, GB2, etc., companies do to their products allowing them to charge 7G and more? I realize one is PI and the other, I think, is VLF (and no, I don't exactly understand the difference...I should have finished my college degree for Electronics Eng.!). Great video, I will try to build one myself!
This is a BFO type detector where the transmit coil and receive coil are coupled and produce no tone change, except when in the presence of metals when the coupling is reduced and the tone of the oscillator is changed.
Excellent! Could be made more compact into a hand held module for finding screws/nails in timber before machining and hidden cables and metal pipework in walls/floors before drilling. This is on my list of things to make. Thanks.
What a beautiful circuit board and so little on it also! This is more or less the "first" video on metal detectors so I have no direct reference.. but I think your detector looks awesome! =D
+electronicsNmore - Unfortunately I've already put my thumbs up already ;) But I'm checking through more videos, so you will surely get some more thumbs up =D
Have you tried different transmit frequencies such as 2200m, 630m, 160m, 80m, 40m 20m, 10m, 6m, 2m, 1.25m, 70 cm? Have you tested your transmit coil for SWR to verify that it is tuned? Have you tested using different wire thicknesses as that can change bandwidths?

Great video fella, again!!.... One thing... what setting do you measure henry's in? I was under the impression it was ohm's but I might be well off. Thanks again
Hey Martyn, You need a DMM that has an inductance setting for Henries. If you don't have one, you can buy a decent meter at a very reasonable cost on Ebay(Under $35). A good DMM for everything else except inductance would be the Vichy VC99. They are $35 shipped. Thanks For watching. Be sure to share.

Larger coils locate larger objects deeper, smaller coils find smaller objects better but with less depth. You can experiment with a different # of turns, but I do not think much change will occur. Thanks For Watching!
Sir! How many turn do i need when using 0.3 mm wire? Ps: i did the same project using 0.3 wire ( 50 and 70 turns ) but there is a big noise even when i turn the pototiometer it decrease a little bit but thats it
@@electronicsNmore Sir I did but there is always that noise. I tryed without one coil and without both but the same thing happen I dont understand why is that. I added a temporary pototiometer with 10k between one wire from the 70 winding and the ground and the noise decreesed What could cause this problem sir. I need your help because my knowledge about electronics is very limited
Hi sir i watched the video carefully and I m very fond of these projects. plz excuse me to ask you whether you brought this datasheet from the mkll locator or no and thanks a lot sir.
I have a video coming up in 5 days showing how I made a small 10T POT with a knob. If you do not use a 10T POT, the sensitivity adjustment can be very difficult.
ok i will wait until your video is uploaded!! ive been making your projects i 11 project i already done and they were all usefull like inverter pwm,generator,auto cut off for battery charger

how hard would it be to add a pot and circuit for a discriminator, possibly a switch and circuit for switching between all metal or disc modes? ... overall i like the basics of the control box, pipe/shaft. not a big fan of the tiny coil and coil assembly.
HI, great project. Thank you very much. I have a question, how can one change the tone so that is resembles more of the high-pitched typical metal detector sound that I've become accustom to? Thank you!
