On behalf of jan w I'm attaching a schematic from above. The previous link is dead.

Hello Sid,
I appreciate your attention, but here in Brazil there is no such search coils and the detector itself or to sell.
I tried various ways to purchase and get the search coil on websites, but they are not sold separately.
Unfortunately, I got the detector stopped, waiting and always trying to get you to buy this reel ...
If these detectors Chinese manufacturing assistance would have had more credibility, because until that work reasonably well within its category and price.
I am grateful for the attention, and I'll be enjoying the posts regarding this issue whenever possible ...
A big hug!

Hello everybody!
I've been following this topic because I am most interested in and without the search coil to solve my problem, because I have a detector but without the coil ...
I even propose to make a proposal, I paid for the making of a search coil, and paid the freight, just trying to get a coil for my detector is stopped here at home.
If you have someone expert, and can confection it for me I would appreciate it immensely.
I leave a big hug to all, anxious and waiting for the results of this topic.
Thank you!

Hi gaucho1961. I am fairly certain that most Chinese Metal Detector Coils will work on your detector.
If they operate on the same frequency, there is a good chance it will work on your's.

I have used the MD3030 detector coil on a MD1023/GC1023 and works great if not better.

If you can find any Chinese made coil in your Country Brazil, you can easily wire it up for your detector.

Cheers Sid

Here is the New link to the schematics file 1018-f.sch file for to download: http://speedy.sh/AGfKh/1018-f.sch
The older one at post #16 don't work any more
With this file you use it in ExpressPCB or similar programs who can read this file and then make your own PCB

I sold this detector a few months ago, so this is all there is from my site, i can not take any measurements at this PCB again

The only one with the original PCB file and the parts list is the manufacturer and i don't think that someone will get a copy off that

You did not understand me, I asked: Do you have mounting board (PCB) FOR PRINTING AND DESIGN IN PDF OR Eagle

[technos]

I wouldn't call this detector's performance stellar imho;

But I like the analog meter.

[technos]

Dose anyone have PCB and part list

Also R80 thru R83 need to be assigned values.

Dose anyone have PCB and part list

Upload the schematics again with some bug corrections, I believe it is correct now.

Hello Sido,
I want to thank your attention.
Yes, I have a GC1018, in fact, believe that these models should work identically equal to one another, whatever the Famous Trails MD9300 Advance, Titan GC1018, Gold Century, finally, I think their design electronics are identical and should work the anyway.
I've posted some time ago on this coil, and hoped to have solved the problem, but I ended up not being able to buy the coil.
There it is:

http://www.geotech1.com/forums/showthread.php?17792-Where-can-I-get-the-search-coil&highlight=1018

I'm needing a detector that has the power to detect objects at greater depth, because I have only 3 of the Bounty Hunter with the search coil Magnum 10 ".
I thought about buying a search coil BLUE MAX 15 "(6.59 kHz) of WHITES, operating at this frequency, and adapt the wiring plug Din, for my detector, or try to buy an old search coil used in 6000DI Whites and pro were 18 "in size, and thus have this detector only for use search objects buried deeper. What do you guys think of this idea?
I know that there is also a search coil Blue Max Loop 950 (6.59 kHz), which has the same size as the original GC1018, but if it is to do something different, so I'd like to do something I'm needing a tracker detector that detects objects deep.
Sido, I believe you understand my placement, I understand that, and is an expert in the area of electronics, so I would rather that you help me assemble this coil, or maybe two of them one of the other larger proportions of the original size detector.
From now on I will be grateful.

Hi gaucho1961, I know as much as the average person here. Always learning.......I do not own the GC1018, but if you follow Jan's coil parameters for this detector.....you will be able to produce a larger coil......but please understand the larger the coil, more problems may be introduced in the detector due to the larger coil perimeter causing a larger "Ground Effect" due to design limitations.

Some adjustments to the detector may need to be done?

Why not try to make the same coil size (first) with the data above and then move to a larger coil or smaller?? A larger coil will cause you more problems. Experiment with different wire size, but stick to the size that does work for your detector as above.

I cannot tell you what will work....just experiment with the data above.....And dont forget to null the coil and Faraday shield it, so to have any chance of working ok.

Other commercial coils in the same frequency range may work, but i have no idea which ones. The whites may be suitable as Carl gives a mention, but i am leaning to smaller coils as the Bounty Hunter coils work in the same frequency.

I do not have all these coils here to try, so can only speculate.

Cheers Sid

P.S I dont have the same detector, but same operational frequency as any other Chinese V.L.F Detector.

Another thing,
I commend the wonderful work they are doing, I think it should have more threads like this, because I certainly would remedy the many community members!

I agree with you. What Detector do you have?
Model?....pictures? PCB?.....The more Pictures/photographs will help?

The imported Chinese detectors seam to operate on a uniform frequency of around 6.5khz, but vary in coil Inductance parameters and capacitance resonant Frequency selection.

Your question about Bounty Hunter Coils is a relevant one as i believe may work, but post your Metal detector photos and working frequency of your detector (if you know) and then can determine if a commercial available coil may work.

So far i see that the BHIV 4 inch coil may work and waiting to purchace one to try it out now.
It is easy to build your own and Faraday shield it to work okay.

The Specifications look similar, but TX oscillator may be different design with the TX Capacitors and oscillator components may be different, which may or not work with your Detector with BH Coils.

Do you have the GC1018??

If you do then i can provide you with the details to build your own.....providing the data supplied so far from Jan is close to original and accurate coil parameter measurement supplied for GC1018.

Dear friends,
I'm watching with great expectation of you posts.
I have an equal detector that had an accident, and the search coil broke.
I'm trying to buy another so I can retrieve this detector is stopped and unused. If anyone knows where I can buy a new search coil for it, please kindly inform me.
I take this opportunity to ask if the search coil Magnum 10 "Bounty Hunter detector that can be used? The frequency of operation appears to be the same as the 1018, or am I mistaken?
If so, how to connect the plug Din in relation to the detector 1018?
Could someone make me a design that facilitates the link to my work?
Thank you in all the attention they can give me.
Thankful!!
