Metal Detector Repair Forum- May we have one ?

I would like to ask the people who own and run this forum if they would kindly consider a section :" Detector Repair Forum". I think for those of us interested in the inner workings or detectors and restoring old machines this would be a nice thing to have.
I do a few repairs to detectors as a hobby but find there is absolutely no where to get advice and discuss problems with other repairers. Maybe some one could look into this.
 
Great idea but, unless you have electronics experience, know how circuits work and components work, can read schematics (if you can find one), have proper testing and calibrating, soldering equipment, your more likely to make the situation worse.

I don't think the guys who know, who also repair machines for a living are going to give out free information.

The best an average person might be capable of doing is possibly cleaning an a old machines potentiometers with the proper cleaner spray. Many make an attempt to fix a problem, only to make a bad repair, orig. problem worse and then try to sell it off on ebay etc., where many end up. Eventually the machine becomes a parts machine after attempts to fix and undo fixes made by the previous owner(s).

If anyone wants to play inside a machine or learn more, best bet is to join the Geotech Forums.....that should scare enough "wanna be tinkerer" to send the machine back to the factory for proper repair.

But, hey if you got $20-40 into an old machine that doesn't work, then decide you want to play inside....go right ahead, could be fun......

Be wary of machines on ebay that say "does not work", you want to know if there was an attempt to repair it by an unqualified person. If so, it could now be a real junker.
 
I am new to this Forum but i think this is a great idea from my standpoint I have a 1960's 1970's Metrotech 220 Metal Detector but the brown wire has come detached in the bullet head control box/battery compartment but with a 'Repair Forum' the answer to my problem would probably be answered easily, having said that anyone know where it goes so i can get it up and running instead of it languishing in its case when it should be being used.
There are probably lots of simple faults that could be sorted out on a Repair Forum from other Detector users experiences.
 
Why can't someone, who has a question about a particular machine's repair methods, ........ simply post on the most appropriate forum (like for that particular brand, or in this case a vintage type, etc....) and just simply title it:

"Question to fix a such & such detector repair please"

Because when you start adding scores of suffix venue sub-forums, is the day that there's simply more forums that no one reads (too many to scroll through). If someone is educated/interested in a certain type detector, he tends to read that particular forum, scanning the titles of threads for whatever interests him to chime in on. Certainly he would see the title for that specific question, and simply chime in.

When forums start getting oodles of sub-menu niche categories, you will immediately notice that only the main topics get the traffic, while no one tends to check the niche forums. So simply make your question known in the forum-by-which applies to that machine, with title to fit, and ..... presto.
 
You're going to be in a pickle with that one, no matter how specific forums become. Because it's just going to be a plain fact that the last of those machines were seen in use, in the very early 1970s (maybe mid '70s by a few hold-outs). So the odds of anyone who was detecting 40+ yrs. ago, and being of a tinkerer type, is going to be a rare person indeed.

Anyone from those days, that also used to work on them and tinker is ........ probably long gone. However, there are some collectors that simply have samples of those in their collections. So it would simply be a matter of asking one of them to open theirs up, and take pix, so you can see which wires go where.

So perhaps your thread title could be "anyone else have a metrotech still lying around ?".

Heck, I bet you could even find one on ebay if you watched long enough. And I bet it would sell for a pittance (since there's not a lot of vintage collectors, and the machine is way too outdated to be competitive now). And you could simply buy it up, and then study and compare to yours.
 
Thanks for your Information Tom, I will heed your advice and thanks again for putting me right regarding posting on this brilliant Forum.
 
There should be one on E-Bay still. $450 so not a cheap buy. Last one on Preloved (complete but not working) was £100 ($160) . Lots of vintage detector owners over here but they like original and working models.
 
Thanks for the reply UK Brian, I did see the $450 one on ebay and emailed the guy that was selling it but alas no reply to date.
 
What a price though....on the other hand I've been offered double what I paid for it for my old Deepstar pulse which must be going on 15 years old now so if good condition and working well a detector is not always money down the drain.
 
I have a Metrotech 220, I will get a picture of the wires when I get home. I have the manual and schematics too but would have to find them. I had to re-solder the wires when I got it from my grandpa and got the manuals from the company about 20 years ago. The potentiometer needs cleaning from time to time too but it still works!
 
Posted the pictures on your Metrotech 220 thread.
 
There's already a "modificatations" sub-section here on Findmall. Eh ? I would think that would also imply "... repairs" as well.

I had a Metrotech 220 and the entire electronics was encased in a solid blob of epoxy. Metrotech said they did that to keep the electonics stable.
You couldn't see any electronics or do any repairs unless you wanted to chip away at the epoxy.
Great little detector, found treasures as deep as 3'. (a bag of railroad date nails)
