Garrett GTI 1500

[ivconic]

I apologize for starting a new topic and maybe I already posted some pictures somewhere, but I can't find that topic, maybe I didn't, maybe the topic doesn't exist.
In any case, from recently I have a GTI 1500.
I used to have 3 pieces of GTI 2500, over a period of 15-20 years, so I would sell them and then regret it!
Yesterday I went out into nature with the GTI 1500, to remember the good old days.
I have a dozen or more detectors.
But I wanted to take the GTI 1500 with me.
In the room for short tests, it showed no flaws.
But yesterday on the field... a cold shower!
It worked fine for a few minutes and then it started to "bug" and "freeze".
The ON/OFF soft button sometimes worked and sometimes it didn't.
Taking the batteries out and putting them back in was the only thing that managed to turn it off.
But after taking the batteries out and putting them back in, sometimes that didn't help either.
Then I found that I had to wait at least a minute before putting the batteries back in, for the capacitors to discharge.
And so with a dozen or more interruptions in work, I managed to search for a couple of hours.
I even found an ancient Roman coin.
Today in the workshop I opened the detector and inspected everything. Everything seems perfectly fine.
I even replaced the spiral cable from the pcb to the batteries (it's the same as from the phone receiver on the old phones).
Long story short; in the end it turns out that the flat cable from the keyboard chirp and broke at the very end, about half a millimeter.
I shortened it by 1mm with scissors and now the detector works fine.
For 20 minutes I turned it on, turned it off, "tortured" it in various ways... it showed no flaws.
We'll see. I hope the problem is solved.
But I have not been able to correctly determine which soft button goes to which pin on the flat cable connector.
It's too complicated and I don't have much focus.
It would be good, for future eventualities, if someone posted here a "schematic" of that keyboard with flat cable leads.
There are 8 strips. It may need to be reworked in the future.

The GIT1500 came to me without the battery covers.
I know from before that they are often lost or damaged.
My poor drawing skills... it didn't turn out perfect but it turned out well enough.

I always say that you are a very smart person, Ivconic....

[ivconic]

It is more accurate to say "committed hobbyist". But sure thanks!
The GTI series is not to be underestimated even today.
From last year until a few weeks ago, I had some "euphoria" about Deus 2, ML Vanquish, Equinox and since a month or two ago my friend has Manticore.
We go sporadically to the fields and search together.
All in all ... these newer models are NOT ONE LITTLE more successful on the field than the older models, especially the GTI, 1266XB, CZ6... Deus 1.
Since last year, Serbia has been full of Deus 2 and ML Equ and Manticore models. General frenzy and madness.
There is a popular proverb in our country: "a mountain shook - a mouse was born".
I look at all that and come to the conclusion that it is much smarter for me to collect old legendary models, make a collection, enjoy working with them;
rather than chasing fashion and buying what everyone is buying today.
Because these new toys will be present on the market next year, and a couple of years after, and the price will be significantly lower.
While the legendary models age... they are getting harder to find in good condition, if at all.
A friend with a Manticore and two friends with a Deus 2... they didn't do any better on the fields than me with an "old" detector.

Ivconic... I have a question for you..how would you compare Deus 2, Manticore and GTI in terms of the number of good non-ferrous targets dug...vs unwanted iron..?

[ivconic]

I have no experience with Deus 2 and Manticore.
A couple of friends have these models... who (among us) are serious ignoramuses, so it made me reluctant to even get interested in the details.
I can't give an objective comparison because my knowledge of Deus 2 and Manticore is ZERO.
I know one thing for sure; I will never have either Manticore or Deus 2.
Not because of money (money comes and goes, that's not a problem) but out of some kind of whim.
Many others bought those models before me, I had the opportunity to indirectly see what and how they work.
I feel like I'm not getting anything useful with those machines that I don't already have with the machines I have in my collection.
One day (probably I won't be alive in such distant future) when those two models become "old legends"... maybe, just for fun, I'll add them to the collection!
Kidding aside. I have no experience, I can't say a word without it being accurate and objective. And I don't have the slightest urge to buy those models.
Like I said, I can't see these people doing any better on the sites than people using even the most modest DIY. I'm not kidding this time.
The point is that all the famous sites have long since been devastated and empty, there is nothing to be found. So why waste money on new expensive toys that offer no advancement?
The only point of having such a detector, as far as I can see, is if the hobbyist wants to play on the prepared training ground in the yard behind the house.
That's why from last year until now, I've "slowed down" a lot and I don't have any desire to buy a detector anymore.
Except the old models for the collection if by chance and unplanned they turn out to be very cheap.
Going to the real ancient sites is now a total mental relaxation for me, without the ambition to find something.
Even the weakest detector from the collection is just as good and successful as the most expensive one.
A lot has changed from last year to now. I lost my motivation. I turned to other aspects of electronics.
Detectors are just toys for collecting and building a collection. There is no other use for them.
