- HOW TO DIY ONE OF THE BEST METAL DETECTOR CIRCUITS is a premium Interactive video Tutorial. See bottom of Description for The Gold, Coins And Treasure Ebook. This video is focused on the Goldfinder Metal detectors, and how anyone can make a decent power metal detector for themselves. My Goldfinder XTR Metal Detector has been very popular in the past, so I decided to create a series! As with Gold on the Beach 6 Platinum, and GOLD ON THE BEACH 10, we continue to provide helpful how-to videos and movies, with helpful hints and tips we have learned from our many Treasure Hunting Adventures. See our 10 live gold finds on camera and learn how and where to find Gold nuggets with our video, - how natural Gold occurs. Gold on the beach and finding large Gold nuggets is always exciting, so come watch this show with premium content.
Important: Read this description.
Finding valuable items is all about finding the right spot to detect and not about buying an expensive detector except if you want to find gold nuggets, then you will need every advantage you can get, so you will need to spend quite a lot of money. If you want to build a metal detector with decent performance go to the on line shop and buy a kit or two at ----www.silverdog.co.uk/shop/index...
They are tricky to put together, but if you are careful, you can make a very competitive metal detector for a fraction of the price. This video is accurate and specifically designed to make it work. It is not quite as good as the Goldfinder XTR, but it is none the less very good. You can however use my smaller Goldfinder mono search coil at • HOW TO BUILD THE GOLDF... . With this circuit as it has a similar power output.
Important:-There is a problem with the circuit used in this video. The round silver transistor top left hand of picture in video (2n2222A) is twisted and so the tag should be facing down not up as in the picture.
The people who design these pulse induction circuits are the technical elite. Everything I know about the Barracuda legend metal detector is in this video so don't ask me questions I can't answer. It is a very good detector circuit for water, salt, and normal ground conditions, - even under water. Not good for Australian Goldfields because I believe the balance is far too slow at compensating for highly variable ground conditions. Yes it will find fishing hooks and such but if there is gold you can bet it will not miss that also, it as it responds to gold items with a very clear and loud signal. But above all enjoy the project.To Buy The Gold Coins And Treasure EBook,- Best Price, Click this link,- www.amazon.com/dp/B07YLL9PTR - วิทยาศาสตร์และเทคโนโลยี
Some soldering / board making tips, fix the smallest and closest fitting components on the board first. Use a piece of sponge over the loose components grip tight and invert then they do not fall out, build slowly away from the PCB. IC sockets, tag two opposite corners, invert and check they are flat if OK solder in, if not you only have to unsolder "1" joint.
Great job Freddy, just one tip if I may. I did quite a bit of micro soldering on missile launchers in the US Navy so i've done much of what your doing here and I gatta say, you do great work, to help from soldering two or more posts on you din plugs together it's good practice to start furthest away from you this way the fatter part of your irons tip doesn't get near the previously soldered pin. Probably a tip better suited for the more amature guy who may be watching this. Just a tip from a guy who's soldered 250 pin 24k gold "cannon plugs", the screw in type. Love the project buddy, very nicely done.
I am a true novis however
Good video, thanks, and I would like to add one advice, when adjusting the blue trim pots (variable resistors), make sure you do not use a metal screw driver, it will alter the detected signal and will give you wrong readings, rather use a plastic trim pot adjuster or anything non-metallic. Thank you again mate.
Never thought of that.. Thanks Omar
I know this is an old comment... but is that because of induction?
great done Frederick
nice
, looking forward to your next vid on the Barracuda
After watching this inspired me to build one, unable to 0 volt at pin 6 (mine 3.3 volts lots of turns few Milli-volts of adjustment, what amps does your draw? mine 2.63 amps and mosfet get very hot quickly as well as the battery pack, thanks
hi Frederick. i am totally new to this area. do you have any blue prints which i can print out to build a circuit from scratch using a standard pcb board or breadboard. any help will be much appreciated. thanks!!
Excellent video, how big is the virgin plate where the components go?
Real people keeping it real, thanks guys1
I am just in the process of building a barracuda rev a. The trim pots on this board are not marked for orientation in this kit....so this video helped me in that way.
Takes some skill to get it right....
G'day Fred.
Just purchased a barracuda myself. You have the best cuda vid I've seen. Just wondering why you have a diode/capacitor on the underside of the board.
Great video, thanks Frederick! Your other videos have been incredibly helpful also. I've just started getting in to detecting (this week), but a decent detector is well out of my financial reach at present, so I'm going to give this project a go.
Would you be able to give me an idea of what type and size coil I should build to give me the best chance at finding small gold nuggets in soil with reasonably high mineralisation? I see all sorts of designs floating around, though I don't understand enough to know which will work with this circuit. Would I be correct in saying that this circuit is limited to mono coils?
Would you say this circuit performs better than the Surf PI?
I like Minelab Equinox from what people tell me.
Depends on the size of the gold you may find. small coils are best for small nuggets.
Hi on the site they have the circut board up for sale,, but those the rest of the parts are comming whit it, or it is a separate order, thanks
Hello Frederick! Thanks for the awesome video. I'm planning to get started on my own metal detector but need a little help answering a few questions if you don't mind, it would be highly appreciated.
When purchasing this kit from silver dog, does it come with all the on board components?
Is the barracuda legend considered the "control box" of the metal detector?
Also what are all the parts that make up a metal detector such as coil,headset,etc.?
sam qadd Q1 all components except headphone jack and the rest of the metal detectorQ2 i call it the control boxQ3 coil, adjustable shaft, hand grip, arm rest- a manufacturer would have diferent names and more detailed descriptionsi have videos on how to make the rest of the detector, but my ways are diferent to most others, and it is not an easy project
Thank you much! This is very helpful.
As it is a very cheapest way to make an metal detector basics and principles which are explained with a model illustrations and a very needy kit making methods and materials are very nice to understand better -thanks a lot !
Srinivasa char A V a bit more tricky than it looks but works very well
Hello Frederick, i have a question for you, The surf pi 1.2 (XTR) is better than the Barracuda legend ????
If you got a comparison it would be awesome.
Regards
Both are pulse inductions with 12 volt input but diferent circuits, the surf pi is particular suited to salt water. the baracuda works well on normal ground and salt water.
Thanks for your video, really helpful!
Can you please tell me one thing about those black ic chips: are they out-of-box ready for making a metal detector, or they require additional programming? Also about other parts, do I simply buy them in electronics store and expect my metal detector to work?
Thanks in advance, keep up the good work!
Already programmed but best buy the parts and board from silverdog in england
Baracuda detector doesn't have any microprocessor hence no programming is needed. All parts can be bought in electronics store. Silverdog sell the Baracuda kit as well as the PCB only.
Thank you for this great work
Romania Gold Recovery.This work has interested me so much
I would like to buy as a set if possible😊😊😊
Sorry Ayhan we do not stock the parts , the circuit board featured in the video was a one of proto type . Thank you for your support and best wishes
Hola.Me can you say control model as volume and gain control post.
Thanks and regards.
Really thank you for a great work and a great video, you are a great man, many thanks.
Lots of work but very interesting....
Goldfinders I just tried to get a kit from silverdog but not success :(
Hi
Can you please help me to finding a kit ?
Many thanks
HI Fredrick
Great video well explained on how to do the basics of board and circuit set up and solder.
What Voltage is the unit working on ( 8V 9V or 12V )as there are no instructions or parts list with the Kit I purchased last week.
Also just to confirm the Coil you made was it on a 250mm Diameter former also the wire 0.5 dia x 20 turns is that correctas I have seen another site which gives 250 dia 0.4 wire x 22 turns Thanks
Ron Gill Better off with more winds on thicker wire. in other words go with 22 turns at .4 as it shouldnt damage the board with too much resistance. Any hook up voltage below a solid 11.5 will cause it to become erratic so it is a 12 volt system and very power hungry too.
Your video is good. What is the range it will detect the metal?
The key is to place the correct component in every pcb location and then solder the components to the pcb pads well avoiding the dry joins.
George George best advice here
Hi guys, love your vidz, great inspiration.
A question please:
I'm going to build either the Barracuda or Surf PI just for QLD beaches, what size mono coil would you recommend and should it be ROUND or OVAL
Thanks in advance
Carsten
carstenvp 8 inch mono is good but need patience and care to put the board together
Frederick Barnes round or mono
I built one a couple of years ago and had to search for the page to show the values of the components and the numbers of where they go. Can you please tell me where that page is again?
m8 yr the man// love to go out with u 1 day/// detecting lolol
Can this circuit be used for a 2 box metal detector?
hello frederick, time ago I built one barracuda back but I could not run and I have seen in your pcb that has not placed some components, nor is there no jumpers
will that was my problem I guess I could say pcs. sorry for the English use google translator. greetings to you
Esteban Alves lots of things can go wrong on the first try.
schmidtt trigger, 2 jfet opamps , and one I can't see properly. I was thinking of building a pll metal detector using a 565. much simpler, can also differentiate between different ferrous metals. which is better?
If you can find a circuit that can tell the difference between ferrous and non ferrous then it is better
good video ,great done
Thanks Bayu
Hi Frederick, I have built a few Surf PI's from Silver dog (all testing and tuning but never field tested), have you experimented with any other coils ? i found that the basket weave was better than the mono's when it comes to smaller gold. Have you built any other kits ? and which machine do you prefer the surf pi or barracuda ?
Congratulations they are not easy,- i like the Barracuda mainly because i find it easier, i would like to see your basket weave coil . i found mono elliptical works best for the Barracuda
i have to agree, i messed the first one up, the second one i made a water tight tube that wasn't very water tight and lasted a few seconds when submerged, i have a few more boards that i will put into housings when i get back home, I'll get a video of the coil up and will post a link to you, the basket weave is a lot harder. Ill give the Barracuda a try, i have been looking at building something i can use in a gold field, as my go to machine for the beach is a excalibur.
Goldfields are exceptionally difficult, all detectors struggle,. the minelab and whites are the only 2 i would trust to find Gold.
I'm not from Australia and I'm not sure what do you mean by "goldfields" and "gold". You're saying you wouldn't trust Baracuda from your tutorial to find any gold, or just gold in "Goldfields"? Excuse my stupidity :D
probably he meant Victoria Goldfields
Thank you Frederick for this awesome video like alway good stuff ;)
Do you will make a video test with it ???
You can How to build the Goldfinder XTR videos as it has a similar power output
Frederick Barnes Ok thank you.
Not the most powerful output, but power works as a paradox... Seams to be better but is really not true.
hi I have got a goldenmask detectector , powers up but can't increase sensitivity, works well , but no change from zero to full sensitivity, any help would be appreciated thanks, Stuart
I would not normal recommend taking apart a detector and i am no expert but it sounds like the turn pot or part near it has failed.or the batteries are failing...
Very nice video, a complete tutorial, 2X thumbs up, Is there a newer model or an upgraded version, since this video is several years old, esp,. since electronics are always being upgraded? thanks again, great work!
Cool Thanks..
Started soldering this board today then got stuck,The delay pots(Blue ones with adjusters)are
different.Both have 3 pins,but on one the middle pin is offset,On the board were they fit both places have 4 holes.Does it matter which way they go.Any ideas.
There is a little circle on the board for the brass adjust screw. one is towards the outside one inside, follow my picture in video.
Hi,The board looks slightly different to the one in your video,I can just see the one on yours,But nothing on mine,Might have to fit them and see what happens,50% chance it will be right.Your videos are really helpful...Big thanks.
Think I found,On silverdogs web site it says" 3/8" multiturn Cermet 100K offset legs" So the other one must be 20K.Right were's me soldering iron.Thanks
GDAY I'm from Adelaide SA interested in building the detector shown by you guys my question is where do I purchase the barracuda board mentioned in the video any help would be much appreciated
Yours sincerely Thomas LaRoche
thomas laroche I cant put the address of Silverdogs shop in England here.it is in the video.keep in mind that is not easy project but i have as much as i know in the description and video to make it easy for the layman.

Hi . what is 4001 zener diodes i can't find. What is it names ?
Hello sir,,!!!have a nice day,,can i have a complete detials about this detector frpm you sir,,thnx..
This might be my next project. I do have a question on a different detector. The Twin Loop Treasure Seeker. A P.I. detector by Robert and David Crone. I built one and haven't got it to detect anything! I own 4 detectors and have made 3 others. 31 year old magazine article about the Twin Loop T.S. left out that the circuit board needed top side jumper wires and a discrepancy of coil winding #, 24 or 30. If you have any info on this Treasure Seeker circuit, please let me know. Thanks. Robert and David might be pretty old by now. If this detector in the video above has trouble in Australia, it might have trouble in New Mexico. Any feedback from people in New Mexico that have built the detector in the video? The Garrett Infinium works out here, I dug a hole 3 feet deep, 2 feet wide only to find expanded mesh screen. Good exercise.
Can't get the parts now and it is a complex problem to say the least.
where can i find this kit to buy it?
I have to boards one is half done I need parts I got the surf pi 1.2 Longboards to
Hello, fellow! Where can I find one of these kits for purchase? Silverdog does not seem to be online. Thanks.

i take a bib sound lol can you recomend me what battery to bye??? now im using 10 aa batterys
and the problem no is i have all the time the bib sound doens stop what you recommend?
Vagelis Vog not AA batteries as they will run down very soon. need lots of power and at least 11.5 volts otherwhise it will run erratic. li ion are best
Frederick Barnes thnxx a lot one more question what cable you use from the coil to barracutta electronic system??
Vagelis Vog I use any insulated wire that is larger than the coil wire, and it works well.. just remember that any metal around the coil when you connect the power will cause it to temporarly shut down.also careful you dont connect the power wrong as it will damage the board. some one told me that one of the large black diods in the top right hand corner is in the wrong spot in the picture.it will work but it is not protected from wrong power hook up.
I like your video I have made it but I have a problem please help me in the special audio section the sound is small and the transistor gets hot, I hope to get a solution🙏
I have provided support for you too🙏
sounds like the coil output wires touched and have shorted and burned a part. or the back of the circuit board has not been cleaned with alcohol. (silicone chip short)
Wooho 10 thowed you
y.r great man th y
Which of the kits listed on silverdog is best for finding steel parts deep underground lets say up to 1,5m
i don't know.. usually the largest coil will pick up deepest, but that means it will loose sensitivity to small pieces. recommend Whites TDI with Minelab 18 in coil or similar.
Better still, old GPX with 24 in coil
Goldfinders ok i understand the coil size but what about the three kits that are offered on silverdogs webpage. What is the better kit?
The Baracuda is a 12 volt kit that will not be powerful enough to support a large,- coil i think. however it will pick up a beer can 2 feet with 8 in coil. i would ask the supplier as i haven't tried large coils with another circuit May be a higher voltage system will work. The people who design these circuits are in a league of their own.
Gaday mate, the link to Silverdog no longer works so do you know if the kit can still be purchased? Cheers
great idea and so much fun is disappearing silverdog was the last to sell the kits.
@@GoldfindersAu My name's Nakhon I'm from Thai land If I need to order the kit can you tell me about the price how much all together?.
@@user-ci7wo2is1n Can't get them any more.
@@GoldfindersAu Thank you so much.
how much does it cost for your metal detector pcb only, and were can i buy one
+ganga j Our detector is a one off prototype.You can buy a subsitute circuit from silver dog in England. Baracuda or surf pi. They are very tricky to put together right but
Hi bro where did you buy pcb and accs?
They are not available any more
Please help me get a diagram for making the detector at 6 m depth and thank you
Need Ground penetrating radar.
Thank . Can you help me make a powerful device for good distances from 3 to 4 meters
Hello sir can I order this pcb main board?
nice work.... but this circuit doesn't have anything in the way of discriminator. Great for beach, sand.... not so good inland...
i think you should try PIM-2 detector
????
Goldfinders pim2 is a pi detector based on microcontroller and it has a lcd
You can search on youtube. Building part a bit hard. Producers earn money from this job but older versions of this circuits, they post to forums. Result is awesome. It reflect a coin from 40-50cm.
Sorry my bad language.
checked it out and it sounds very good. large coil capabilities means better performance. overcoming ground conditions is a major problem however.
OLA. Este projeto parece ser muito bom. Como posso conseguir este projeto aqui para o brasil.? A empresa Silverdog não fornece este kit aqui para o Brasil. alguém ai teria os arquivos e como fazer este PCB. Obrigado. HELLO. This project looks pretty good. How can I get this project here to Brazil.? The company Silverdog does not supply this kit here in Brazil. someone there would have the files and how to make this PCB. Thanks.
There is no listing for this kit at that site???
Brad Haas i just got the word that the baracuda boards are in high demand but a new shipment will arrive very soon. leave a message at the site if you wish
hello How do i get the circuit board schematic?
Which Coil did you used? Is there a tutorial how to build a Coild for this KIT?
22 winds of .45 copper at 8 in dia wire works good.
Variety channel shows how, see how to build My crazy invention.
@@GoldfindersAu thanks. Could you provide a link for me please?
th-cam.com/video/iZkjKn_GyPY/w-d-xo.html
but keep in mind that i am a novice at electronics
I see the black goes on one terminal of the pot, Does the positive go on the other pot terminal ?
+patprop74 Stop the video and note the time, commemt to me and i will try to answer you accuratly
+Frederick Barnes //\\ time index 14.44 //\\ you have the negative alligator clips on the green pot wire, my question is, the positive connected to the pot ?
+patprop74 Positive (red) and negative Black) is hooked to pos and neg which is marked on the board
I use different color wires for the pot and audio out so I don’t get confused and hook the power wrong. If the pot is wrong it won’t work, -hook power to it and all your work is destroyed
When do you think you might have more kits for sale?
i dont sell them
what DIY kit would you recommend for use in the gold fields?
It would be great if you can use it on the beach too.
Phreaker The hammerhead has control over its operation.However detector companies which solve that problem ask a premium for their detector because it is the most dificult problem to overcome.Goldfield areas are often full with conductive material, especialy in Australia. it is like finding iron through iron. in other words most detectors see the goldfields as one big iron field
hi barne very good your video but can you help me with the conection of batery and on off botton where i put the cables??
Vagelis Vog Look on the front of the board and put a pin through the positive then negitive hole , same with the audio, mark them somehow as you dont want to get any wrong. hope this helps.
Frederick Barnes solder small pins or bits of coloured wire so you dont get confused
hi barnes again can i make coil from 0.4mm or i need 0.5mm and how many turn???
i bought the wrong one lol
Vagelis Vog if you are using the baracuda with .4 copper insulated wire i would use try 25 turns at 8 in diameter coil. you can experiment so long as you dont short something out or hook the bateries up wrong.if the coil wire is too short it will heat up the circuit and damage it. i have never tried .4 wire and i am not an expert, but but my experience tells me that it should work well as . 5 wire is what i use and it works so long as i dont use too little and damage the board.
first try i turn it on and i see smoke FAIL
Where can I buy this Board?
Should be able to pick up one from silverdog england.. in video description. easy to make a mistake but
Beware I had a circuitboard that look same for a diff. purpose, and found a invisible short circuit between traces. Not completely etched I presumed.

hello how can i get one
until what depth do this work?
The Baracuda is a average 12 volt pi. how deep it will pick up a small gold ring in the dirt with a 8 in coil is around 11 in. all depends on how well it works however ?
thanks I think it is the small turn pot , thanks
Gold rings are on most coin shooting sites. The skill level is high. Most read as junk! they really do..
+Gary Hunter yes- Unfortunatly most detectors see gold rings as aluminium pull tabs
+Frederick Barnes Which is why I dig pull tab signals ;)
Discriminators are useful for finding coins in trashy areas i find

Do you have the schematic for this, I am an electronics person so if you were to give me the schematic it would be easier for me to understand? Do you have it if not could you tell me the name of the board?
No only Anchor Electronics can supply that i think.

are you sure your 2n2222A transistor is in correctly? the Emitter is the pin closest to the tab and therefore should be down the bottom not up the top in yours
Mk2Brett that one worked fine,- but the large black diodes may be incorrect
Frederick Barnes may be the transistor was twisted
Frederick Barnes I thank you and give you credit for your observation i will modify description
Frederick Barnes Thanks, i only noticed it as im building one myself today. Is the input voltage 12v?
11.5 to 13 volts. below 11.5 it beeps
