I Totally lost track, but I know there have been over a thousand of these detectors built, as of 2008, And I will show more Pictures as I recieve them!All Persons Comments will be posted, Even if they are negative in nature. I am not here to sell this detector, But Just trying to offer a good project to those persons that are interested.
Lots of guys tell me they will send Pictures, but the actual pictures I have recieved is MUCH Less than 0.1%.
MANY THANKS TO ALL, WHO HAVE SENT ME PICTURES!
Newest Submissions are at the TOP Below, The older ones are at the Bottom of the page.
Most of the Pictures I have Recieved As of: "July 31, 2017" {Sorry, Some of the earlier pictures were Lost in a Computer Crash awhile ago.}
David's, Metal Detector, in New Hampshire, USA. David said its working well.James, Metal Detector, in Pa, USA. James put it into an older detector case and it Looks Pretty Good. He says it works now, But he still needs to make a Proper Coil for it. Thanks for the Pictures James and I hope for some Updates when you get a proper coil made.

Video of Kayla's Metal Detector in Operation on this Robot, Overall, Everyone were VERY PLEASED with the Results. Thanks for the Pictures and GOOD WORK to Kayla and all the other Persons involved in this project.
Josh's, Metal Nail Detector, in Texas.I Custom Built this Detector for Josh so he could detect NAILS in Lumber before Cutting or attempting to Plane it. It is powered by a 110vAC Wall adapter, so n batteries. Josh gas tried Many other Detectors, But still getting damaged saw blades, etc from Missing Nails in the Lumber. I just recieved feedback from Josh, and he says it works Fantastic. He is now planning on getting a Second one. Thanks for the Feedback.
Anibal's, Metal Detector, in Uruguay. Anibal built this detector a few years ago, but just sent me these pictures now. He is Searching for Gold Coins and other stuff in old ruins. Thanks for the Pictures and good luck on your hunting.
Juan's, Metal Detector, in Chile. I had a bit of a Language transulation problem and Juan had a few problems with getting it working,
but we worked it all out. Juan says: It is working now and Quite Sensitive. UPDATED: Juan has sent some additional Pictures and Comments. Juan says: "After One hour on the beach at "La Serena in Chile" here are the items I found with the detector". "I am VERY HAPPY with its Sensitivity".Thanks Juan for the ADDITIONAL Pictures and Feedback.
Faraz, Metal Detector, in Canada. QUOTE: I have the charger for the batteries and also a voltmeter circuit that I made without a board that shows whether or not the voltage has dropped below 12V. The sensitivity is very good and the detection depth is almost a foot for a ring sized metal object and of course deeper for larger. I also have the 1000Hz switch, which gives an extra one to two inches of depth sensitivity; good to have as an option for fine pointing. Thank you again for all your help and of course the great circuit design!
Thanks Faraz for the Pictures and your Comment. Nice Unit!
Pete, Another Metal Detector, in England. QUOTE: Here is a pic of the Pulse 1 with a new control box. Gone is the plastic see through lunch box and now has a single cable from coil to box as per. It can detect a 1 pence decimal penny on end at 9" in earth. The pulse 2 I also built has no problem down to 14" for same on boost mode. Used the small meter as supplied, Better and less adjustment than the larger meter for my daughter to use. THANKS Pete, for the Picture and Comments.
Ron's Latest Metal Detector" in NJ, USA. This is the second Metal Detector that Ron has made. Ron's built his First detector in Sept of 2010, But it was distroyed in "Hurricane Sandy". This time he bought a coil from me this time, but he sent me a Picture of the Coil Jig he made when he built his first detector in 2002.
I took the detector out for the first time last week and I thought it worked well. I found a US quarter at about 7 inches and lots old beer caps, nails, and an old hammer head. The place I was searching at was where an old house once stood. I built my detector using the handle and armrest from an old broken bounty hunter metal detector, a 3/4" piece of thick wall PVC tubing, and a 6x4x2 box from Radio Shack. I mounted the coil between 2 pieces of thin plywood and used all plastic hardware. I made a battery pouch, which I wear on my belt. With a small length of wire from the battery, I connect it to the detector box.
Thanks Ron for the Pictures and you did a VERY NICE JOB on building it.
Rino's Metal Detector Creation" in NB, Canada. I built and assembled the case and all the components in it for Rino. Rino built the Color-full Coil and did all the Final Assembly. Rino says he will supply info on his test results when the weather impoves in his province NICE JOB Rino.
Pete's Latest Metal Detector Creation" in England. Pete supplied his own meters on both these detectors. He says his Assembly time on this Detector was 2 Days. VERY NICE JOB Pete.
Pete's Metal Detector" in England. Pete had a few problems getting it to work, but after Numerous Emails to me for help, the detector is now working good. He has not had time yet to do much searching with it yet. And now he plans to build another one for a friend of his. Update: Pete says he Found 8 new coins in the back garden today not detected by my Garrett 250, Here are the Pictures he sent me and I hope he will update me more on all this later.
Dave's Metal Detector" in Charleston, Sc, USA. Dave initally had a few problems getting it to work, but the detector is now working good. So far he has just found a few coins, but hopes for Better stuff. Here are some Pictures he sent me. THANKS Dave.
Mike's Metal Detector" in Texas, USA. Mike origionally bought my detector kit in Nov, 2012. (His Previous Pictures and Comments are Below.) Now he bought two more kits in March of 2013. Here are Pictures of one of these he built from his second purchase. THANKS Mike.
Dave's Metal Detector" in Australia. Dave's Comments: Gary, Greetings... Attached are some pics of the finished detector. It is a beaut machine. Very happy with the results so far. No "treasure" found but plenty of trash and a few coins. This detector is more sensitive to small items than I thought it would be. Have found tiny fish hooks on the beach and will detect coins down to 8+ inches. I made some small mods like putting a bigger knob on the beep pot so I can use it as a thumb wheel for adjustments on the go. I also soldered the microphone cable directly to the coil and used a mic connection on the other end so I could run a ground connection to the shield of the wire and, if necessary, to a shield on the coil. It appears that no shielded is necessary. I used an old plastic plate as a coil bottom and just covered the top with plastic. The power supply is a small 12v battery I have on my waist to reduce weight. Excellant machine. Thanks Dave - Australia. Nice Work Dave, And THANKS for the PICTURES AND COMMENTS.........Happy Hunting Gary
Mike's Metal Detector" in Texas, USA. Mike's Comments: Hi Gary! Mostly finished my detector today and thought I would send you some pics! This has been a very cool project and it really got me thinking ahead of time how to lay it out and where to put things. As I went some of my plans changed too. Very well designed board and I really liked the test points! The test points gave me a lot of confidence before proceeding that I built the board right. I bought some 1" fiberglass tube for the basic frame and fiberglassed the handle on and then ran my wires through the handle so that I had the board and major connections in one box and the meter and controls in another box on top of the handle. As you can see it turned out awesome! Still have some mods to do with a shielded cable and cutting some handle bolts off but about 95 percent done. I thought about the coil every time I worked on the board and it was one of my biggest concerns as to how to mount it, wire it, etc. In the end I decided to fiberglass it and embed the supports on top of a 1/8" luan disk I made to fit inside the wire circle. I built up the insertion point for the fitting connection with hot glue initially then fiberglassed over it, and finished it off with some epoxy. Even wrote my name in between coats of fiberglass. Not sure about the exact weight but I think it to be light, maybe 16 oz tops. After doing it about the only thing I might do different is to not use the fitting and fiberglass the entire wire inside the coil so that it would be waterproof up to the first box. That and using some really cool special wood like walnut or zebra for the insert since the fiberglass dries so clear. I used a 2.1mm DC jack to provide power from a rechargeable 12v alarm system style battery that I can carry around in a backpack for some extended time in the field. Will say that I thought seriously about that fiberglass tube and how neat it would be to use it for 8 AA batteries end to end inside the tube! After finishing it today I went out to the back yard and among a few other things I found two aluminum cans that had been buried in the dirtwork when we built our house 7 years ago. When I dug them up they were about 15 inches deep and the signal was still crazy strong! In air I am getting about 20 inches or so on a pop can and about 8 inches on a coin. Anyway, great project and thank you for sharing it! Looking forward to building another soon as I get my workbench cleaned up and back in order! Mike in Texas THANKS MIKE.
Ed's Metal Detector" in Richmond Virginia, USA. Ed says it works really well, "good strong reading with a Soda can at 20 inches in Air". Ed used 1 1/2 inch PVC water pipe, a 1.5 A/H battery in the Control box, Frisbee for the coil base and Green Paint Ed is now considering ordering another detector, so both him and his Grandson can search together. THANKS Ed. Roland's Metal Detector" in California, USA. Roland is still working on making his 4 Foot Coil, But sent me these 2 Pictures for a start. His intentions are to find Meteorites and pull this Large Coil behind his vehicle. So Far, it is LOOKING GOOD, THANKS Roland.
Steve's Metal Detector" in the UK. Steve's Comments: Hi Gary, Well its all built tried and tested and works well went on the beach Saturday for a couple of hours, and to try it out and I found 2 x 1p 1x 2p and lots of trash,, but hey good fun ..my 2 boys (men now) had ago with there detectors (bfo), mine, yours ran circles around them. I can hear a change in tone off a 1p coin at about 9 inches in air. So don`t know how that compares with others that have built your p1.. I would just like to add that without your patience and under standing this would have never been built, and any body thinking about building this pulse induction detector go for it.if you are like me with little knowledge, although I do know which end of the soldering iron to hold I learnt this very early ?????. As I have said Gary is helpful and very patience ......................cheers. THANKS STEVE.
Paul's Metal Detector" in Calgary, Canada. Paul Bought most of the parts from me but he supplied his own meter. Paul says it works Very Well and he shows some of the Roofing Nails that he found in his back yard. He also said: "it did a great job picking up small staples, Twist Ties and even a few pennies". THANKS PAUL For these Pictures.
Chris's Metal Detector" in Pa USA. Ted Bought the kit of parts and is making his own coil. These are Just Two Preliminary Pictures, Chris says More are Coming.
Ted's Metal Detector" in Lawndale California USA. Ted Bought the kit of parts and an 8" coil from me, Quite Awhile Ago. I Forgot to Post his Pictures. Ted seems Quite Happy with the Detector. Sorry I Forgot, But there here now.
John's Metal Detector" in Arizona, USA. John Bought the kit of parts and an 8" coil from me and says he can detect an Aluminum can at about 18 inches. He said he replaced the TL081's with AD711's. and got a slight improvement in sensitivity. ** I Also tried these AD711 IC's with somewhat Poorer Sensitivity than the TL081's. ** "Definately didn't justify the cost difference". He Also tried a Different fet for Q3, as he initally had poor sensitivity. Sometime Q3 can be a problem, But I Batch test all the 2N3819's, before using them in my kits so they should be good. Update: John has now purchase two 6" coils from me to try to detect Smaller Objects. One for my PI Detector and the other for a Commerical made detector. He was surprized as to how much more sensitive it now is to Smaller stuff. Thanks John, for the Revised pictures and other info.
Randy's Metal Detector" in the Belview Mi, USA. Randy actually built this detector in 2008, but just sent me these pictures in Dec 2010. Randy uses this detector for Testing Coils that he makes. He says: the better the coil, the better the sensitivity on this detector and presently he is expermenting with "Dual Field" Coils. He has a Cell Phone battery pack and a Built in charger in his detector case. Thanks Randy, for the pictures and other info.
Bill's Metal Detector" in Telford, PA. Bill made this detector a few years ago, but recently he reversed the battery causing some damage, so he returned it to me for repairs and now its working again. His Previous Picture are "Bill" lower down on this page. Here are some more pictures of it now. Happy Uunting a Thanks Bill.
Stefan's Metal Detector" in Silicon Valley, California USA. Stefan etched the board himself and built this detector using his own parts. His coil is 34 Turns 20 AWG wire, 5.8" ID & 8.25" OD, Coated in Epoxy and covered with Medium Density 1/8" thick Fiberboard. He says it detects a US, 25 Cent coin at 8 to 10 inches and a Car at about 3 feet. Using his back yard as as test field, he says he is finding dozens of bits of old iron, but No false readings. Now Stefan plans to build another Pulse-1 and a Pulse-2 for his family members to use. Thanks Stefan for the GOOD Pictures and your Comments on the detector.
Vytautas's Metal Detector" in Prienai, Lithuania. Vytautas built this detector from his own parts, in an attempt to find his Ring that he lost, And the Ring was found! Thanks Vytautas for the GOOD Pictures and glad you got your ring back.
Tony's Metal Detector" in Portsmouth, England. Diego built his detector from my kit and made a Seperate Recieve/Transmit Coil for it. His large, Transmit coil is 19 turns of 14 strands insulated wire, 20" * 6.5". And the inside Recieve coil is 70 turns of 24 SWG wire, 17" * 4". He is using a 1 Khz frequency and he because of this, he reduced R26 to .047. With this coil, a pulse width is 80 us, delay time of 40 us and recieve time of 80 us, works best. Tony only uses the Audio, No Meter and says: "It gets a positive detection depth of 5.5 to 10" in wet sand for coins and typical wedding rings". (But not for the Small 5 Pence Coin.) (Personally I find my Expanded meter, More Sensitive than the Audio.) He was trying to get the best detection of both Small and Large objects over a 30 inch area, but now is considering a smaller coil also, for Smaller coins and jewerly. Presently he is using Ten, NiMh "D" Batteries, but is now considering using the"AA" ones to reduce weight. Thanks Tony for all the GOOD Pictures and other Info.
Diego's Metal Detector" in Spain. Diego built his detector from Scratch and made two coils. His 5.2" coil detects a 1 Euro Coin at 10" and a Pop Can at 17". His 9" Coil detects a 1 Euro Coin at 11" and a Pop Can at 18.5". Thanks Diego for finished picture.

Dean's Metal Detector" in Australia. More Pictures from Dean. He says he can detect a 5mm Screw head at 160mm, But dissapointed in only detecting a Pure, one ounce Gold bar at only 190mm. He is using a Tesla coil. (That might be his problem on that gold bar.) Thanks Dean.
Dean's Metal Detector" in Australia. Dean says he has not found any gold yet, But numerous other Items. Thanks Dean.
Augustin's Metal Detector" in Sibiu, Romania. He Made the PCB and bought the parts himself. Nice work.
Fabrizio's New Metal Detector" in Toscana, Italia. Fabrizio built this Second detector and he did a good job on the coils. The Coil is a Seperate Recieve/Transmit (Tesla Wound) Coil. He says it detects a Small coin at 20cm and a larger can at greater than 50cm. Nice Work.
Ken's Metal Detector" now in South Sweden. Ken built this detector himself and used IRF740's for the Output. He also used a Factory made coil with 1200uH Inductance and 10 Ohms resistance. He says it works Great, but I think he would do better with Less Inductance, Especially on Small Objects. I'm now waiting for his Country and Pictures of Finished unit, as well as more comments on this coil. Thanks Ken.
Maurice's Metal Detector" in Canada. Maurice bought Two kit from me, and built one for a typical detector and the other for a Conveyer Belt. Maurices Comments: Here are some pix of my conveyor belt tramp metal detector. (NOTE: The following only applies to his application and with his additional circuitry.) This is a slightly modified version of your pulse 1. I reduced the value of "R26 to 1 k". This allowed sampling without saturating IC 10, right up to the point where D3 and D4 come out of conduction. That increased the sensitivity considerably. I can reliably detect a dime at 12 inches. The output of IC 10 feeds some signal conditioning to look for a pulse that matches the belt speed, and a latch circuit. The coil is 4" x 20" square with 20 turns #22 enameled, came in at 380 uH. Your circuit works great Gary, Nice job on the boards too, thanks a lot and have a great holiday. Maurice.
He made own Rectangular Coil for under the conveyer belt And he also created additional circuits to interface it for his system. Thanks Maurice for your Pictures and Comments.
Sergio's Metal Detector" in Brazil. Sergio bought the kit from me, Without a coil or meter and built it up without any problems. (He made his own simple coil.)

Better late than never and It "ALL Looks Very Professional". THANKS Vladis!
Adrian's Metal Detector" in Kent, UK. Adrian built this detector himself using his own parts. He just bought the Circuit board from me. He used two 6 volt Gel cells in series to get 12 volts as it was Cheaper for him to do this. The Batterys are in a seperate box, Not shown. A Quote, One of his Comments: "Absolutely Bloody Marvellous little design!!, Not only boffo performance but idiot-proof too!! (and boy..... I've tested that aspect to its limit!!!) Adrian also made a very Favourable Comment on the performance of my flat coil design. but there was a lot of swearing as he tried to make it. However he is Very happy with the final results using it. He says, Quote: "I can clearly detect a "Bean Tin" sized aluminum light fitting at over 27 inches". Nice Nice Pictures Adrian.
Plamen's Metal Detector" in Bulgaria. Plamen built this detector himself, including making his own circuit boards. On One of the circuit boards Plamen used a "TS1117" which is just a Larger Package of the REG1117. Nice Job and Nice Pictures.
Don's Metal Detector" in Lakewood, Colorado. Don bought the PCB from me, but got the rest of the parts elsewhere to Built this detector. Here are his Comments as in his Email.
From: Don, Sent: September 10, 2006
Hi Gary: Just finished the PI metal detector electronics circuit assembly along with a less than perfect 8 inch test coil. So far am very impressed with the outcome when I know full well that my test coil is not perfect.
Attached are some pictures of the assembly along with pictures of gold and silver items used to test the detector.
First though, I opted to build the detector electronics unit to have a detached power supply that plugs into the circuitry via banana plugs. I also added a DC voltmeter to provide assurance that input voltage from the detached power supply was sufficient and correct. I also added an ear phone plug as an option.
The only issue I have is with the VR2 control to obtain a beep null. The first VR2 I installed was a single turn component and it was very difficult to find a click tone in the range that would be useful (by that I mean just an infinitesimal adjustment would go from a click to a steady shriek). I then purchased a 20 turn VR thinking that would solve the problem. It is improved but still way to sensitive. Any ideas you may have on this will be greatly appreciated. Other than that I am very pleased with the detector and looking forward to experimenting with better wound search coils of various configurations.
** My Note: I have never had this Problem. I think he has an error somewhere.
I'm planning on using a two coil ground cancelling configuration and will probably go for elliptical or rectangular setups.
Here are my results for the test items shown in the photos:
GOLD ITEMS -------------
Gold 1 OZ Australian coin = 12.5 inches flat side and 7.00 inches standing vertical
1/10 OZ U.S. gold coin = 8.0 inches flat side and 2.75 inches standing vertical
3/4 OZ 14K class ring = 10.0 inches
46.1 Gram gold ore sample = 9.5 inches
1.29 Gram nugget = 2.5 inches
1.00 Gram nugget = 2.5 inches
SILVER ITEMS ----------------
5 OZ silver bar = 11.0 inches flat side or 8.50 inches standing vertical
1 OZ silver bar = 10.5 inches flat side or 7.50 inches standing vertical
1883 U.S. silver dollar coin = 10.5 inches flat side or 7.50 inches standing vertical
0.20 OZ silver & turquoise ring = 7.5 inches
ALUMINUM CAN --------------
Slim Fast with ingredients inside = 23.0 inches long dimension or 19.00 top side.
These tests were done with the detector built with the parts as listed in the parts list. I would assume that my unit can be optomized to detect gold nuggets better than this, now that I have pure gold to use for setting it up. And I will be doing so this coming winter.
Thanks, Don
