Garrett GTI 2500

[Wild Bill]

I had a Garrett GTI 2500 for a while and it was a pretty interesting detector.  I think it was one of the longest produced but not real popular.  The ability to size targets worked very well and I don’t recall any errors but that feature didn’t move on to other models that I know of.  I remember a review about a year into its production that found it detected coins deeper than about ninety other detectors at that time but I don’t recall anything else in the review.  Someone gifted me the Treasure Hound Eagle Eye two coil attachment and I did a humorous air test getting a signal on my truck at about 40’ away.  I also was evaluating two placer deposits and someone told me you can use the Treasure Hound to locate deep black sand deposits.  I did and it worked.  One at a depth of 2’ and the other at 4’ and both had fine gold.  I also thought If I was looking for a metal object the mineralization would interfere.  The Nel Big coil also picked up the black sand.  I was doing some pipe welding in an area and used it once to trace another pipeline so we knew to be cautious trenching near it.  The GTI in my opinion was actually a pretty good detector.  It would air test at huge distances.  Heavy by today’s standards but balanced well.  I suspect most on this forum didn’t really like it.  I sold it as I just wasn’t using it.  My first prospecting detector was the first Fisher Gold Bug.  It was a great design and worked well.  A prospecting partner I had years ago also used one.  He moved to the southern coast of Oregon and later passed away.  His brother sent me his detector and said it didn’t work.  I sent it to Fisher and it was beyond hope.  Salt air corrosion had destroyed the circuits so I kept the rod and coil.  I don’t really see much use in it though.  Something to be said for waterproof detectors in a constant salt air environment.  Thanks, interesting older technical specs.  Has anyone compared the new Garret 24k with the original Whites?  Since Garrett boosted coil signal (I think) did it improve performance?

Forgot Garret 🙂 yes i read somewhere that the 2500 was a machine of her own...........but no youtube at the time....

GTI 2500 was made from 1999 to 2024, so it was a long time, but the Fisher Gold Bug 2 beats it in that regard (1995 and still in production).

Garrett did not "boost" anything. The coil was remade to Garrett's manufacturing standards is all (I tested it). The White's and Garrett versions of the 24K are for all intents the same detector, just different colors.

I inherited a GTI 2500 from my Dad about 6 years ago. Tried it a few times, pretty cool the way it worked and was able to tell target size, but it didn't do well in my mineralized ground so I sold it. It had the big 2 box attachment, about 4 coils and a hard case. I don't remember him ever using it and it looked like it was almost new. I think I remember him saying he got it at a detector shop that was going out of business, so he probably got a real good deal on it. For me there were just so many more metal detectors at the time that worked better in my ground, I just couldn't see myself ever using it.

Ah! I remember it well. The first one had white coils prone to failure, mine did. But the plus was the sizing on screen quite accutate, and a pretty good AM mode. Nicely built and with an option for 'treasure talk'. "Quarter dollar" or the like.

First field outing resulted in a 10th century Saxon coin.

I replaced it within a year as I moved onto other models .

The Garrett GTI 2500 was one detector I never had my hands on for testing. Pretty innovative sizing technology along with the  "Treasure Talk" feature at that time. But, I was never someone who enjoyed heavier, chunky detectors and that is why it never appealed to me. Good to remember the old days for sure. I'm glad I still can!

I guess I’ve mixed up the Whites models?  As far as boost to the 48Kh coil voltage.  I’m not very familiar with them.  The Whites GMT is a different model, correct?

[Wild Bill]

I think I got it, they’re two different models of 48Kh operating frequency.  The 24K has higher coil voltage over the other GMT model.  If that information is correct.

GTI 2500 cool for it’s time….. I bought one, didn’t care for it’s enormous size

And that modern pull Tabs and clad Nickels ID The same, drove me nuts in The Parks.
