Hi! IVCONIC


I was very interested in MINELAB GS 15000 and would like to know if you succeeded the list of ICs ; coil and PCB.
You knew something about the characteristics and performances of this detector ?

Thanks in advance

Hello , The schematic is in a PDF file . And pretty good photos of the PCB circuit board have also been posted . The next question is where in the Archives are they ???? I am searching now , but maybe Ivconic or another Geotech Member has information and photos saved already !!! ..................Eugene

DIRCEU , I am still looking , because I found the pdf schematic and it is identical to what was posted 1 page ago or so . And I am still searching for the PCB circuit photos. Maybe someone else will see this post , and attach everything you need..........I will keep searching for anything on Goldseekers 15000.......I thought W. Lahr had a 100% complete schematic drawn up years ago ?????....Eugene

Hi! All

I was searching in the net and I found this

So... who can tell us more details on those 2 unknown ic's?

Hi! MAX.

You are wellcome in this topic.
Please! We need very much of yor help. This is ideal VLF project for me because of high mineralization present here.

is this picture made by you?
i see some screws on box!
if you have screwdriver maybe you can open it!!!!!!!

Hi! PERDICA.

No! I found it at Net. Don't remember the site, sorry.

GOLDSEEKERS 15000 MINELAB

Hello to all in this thread with interest on the 15000
I have one and is incredible on mineralization or black iron soil
It was the first put out by Minelab,to compete against the big brands
And it has an excellent Ground balance so good that in mine
I have pulverized a rusty old nail and mixed it with black soil in a small glass jar.And you put that over the coil and is able to ground balance
it off.While going at the same time with a small 1gram gold nugget and get a nice signal.
Just wondering is their an update of the schematic with all the I.C numbers.I have asked Eugene recently,waiting on his reply.
Mine was a later model when they fixed all the bugs,and one of few made specially made for Hipmount with the small and large coil.
Here are the pics.Cheers

Hi! Mikebg

I'm still interested in this machine unfortunately Mr Lahr when sketch this one, he omitted information about some CI's (intentionally ???).

Can You try to identify these components based on their knowledge?
As hobbyist I believe it is possible and I willing to make this detector.

Perhaps Ivconic made some progress.
Anyway I'll do an experiment with my knowledge.

Best Regards
Dirceu.

I still haven't seen it "in vivo", that 15000.
Last winter i had FT16000, but it is quite another story.
I can open new topic and post few things that i kept from FT16000.
Would like to see more details on 15000 and possibly to make it as hand made.

Hi Dirceu.
This is too old design. I will analyze the functions of ICs and will post suitable models.

Hi again.
I prefer to use in my experimens old opamps type TL06x, TL07x and TL 08x because they are very cheap in Bulgaria and operate enough fast. The sign "x" means number 0, 1, 2 or 4.
In my opinion, the Goldseekers 150000 circuit will operate if you experiment it with following ICs:
IC1 - TL072 or similar
IC2 - TL072
IC3 - two ICs which are different type. The left one IC3 has no supply leads. That forced me to think it is a transistor array. The right one IC3 operates as changeover switch like CD4053. May be the operation of this part of circuit is described in an old Minelab patent of Bruce Candy.
IC4 - according pin numbers, IC4 are two separate ICs. In this case they can be TL061, TL071 or TL081. However in my opinion, Bill Lahr made mistake and IC4 is a double opamp IC.
IC5 - TL082
IC6 - TL084
IC7 - operates as powerful voltage follower with output impedance 2.5 ohm. I think TL084 will do the job.
IC8 - TL072.
However my advice is not to vaste time with such obsolete design.
