GTI 2500 replacement...

Anyone got any inside info or good speculation on what/when the next new "GTI2500" will be? Considering the capabilities of some of the current new Garrett detectors, kinda makes me wonder...



It is by caffeine alone I set my mind in motion. It is by the essence of canephora and arabica that thoughts acquire speed, the hands acquire shaking, the shaking becomes a warning. It is by caffeine alone I set my mind in motion.

It's safe to say there are a lot of us waiting to hear that.

Here are a lot of good words for Garrett, and a few that are critical.

No bad-mouthing is intended -- just a view based on experience.

Background:

... I have been detecting for 28 years, and have come up with plenty of silver coins, jewelry items (some returned after finding), and relics including CW bullets.

... Translation: a lot of time in the field.

... All kinds of fields, from New England to Florida. Some salt beaches, but mostly fields, parks, and homesites.

... Detectors: Fisher CZ-7a Pro and CZ70. Teknetics Gamma 6000 and Omega 8000 Version 6. Garrett AT3, GTP1350, and GTI2500.

... Current detectors are two: the Omega 8000 and the GTI2500.

- - -

OK, now to the point.

Of all the detectors I have used, the GTI2500 is my "go-to" detector.

I enjoy the Omega, and won't say anything bad about it. It's sensitive, stable, and accurate as far as the target "numeric ID" is concerned. Frankly, my two Fisher CZs were just as sensitive and accurate.

But there's a limit to every other detector, except for the GTI2500.

And that is because of the GTI2500's target "sizing" during pinpointing.

After showing the metallic ID, it knows the difference between "large-deep" and "small-shallow".

On all the others, can slow or a lid at 6-7 inches will readout like a coin at 2-3 inches. The numeric ID is similar. The pinpointing "sweep size" when centering the coil over the target is similar.

In other words, on the other detectors ... a "larger, deeper" target will ID and pinpoint like a "smaller, deeper" target. You have to dig to figure it out.

If it looked like a coin at 3 inches, and you're already down 6 inches with the pinpointer barely beeping in the hole, you don't have a coin; you probably have a can lid. (It's probably not a silver watch or coin spill.) You can, of course, take the chance and keep digging. But over the course of several hours in the field, you'll pull up lots of large trash.

With the GTI2500, that doesn't happen (unless you want it to). If the target size says "coin-size at 4 inches", that's what it is. If it says "large at 8 inches", that's what it is. Yes, one can go ahead and dig, just to make sure. But with a lot of experience you find out: it's accurate.

The point is this. With the GTI2500, you know if you're going for a large item, deeper down, or for a small item, shallower.

You have the option "up front", to dig or not dig. You can dig, or take the same time to cover more ground. You can always come back later, if you want to. With the others, you didn't have that option.

- - -

Also, the GTI2500 has the "Surface Elimination" mode, which the others do not. If you're at a old site with lots of shallow trash, but you feel there could be older targets down deeper, then you can set the Surface Elimination to only detect those deeper targets. Again, the choice is yours.

- - -

OK, enough rambling. The GTI2500 -- older hardware as it is -- wipes out the others I have tried. No badmouthing intended. They are all good for what they do. It's just that the GTI2500 goes a couple of extra miles beyond those others.

Minus side: It's heavier than the modern detectors. And it would be good to have a real numeric display, instead of the target segments.

But nothing beats the target imaging, depth, and sizing during pinpointing.

- - -

Come on, Garrett.

I will be among the first in line when you bring out an AT with real imaging.

Please don't call any detector a "MAX", when it lacks a major feature that's already found in another one of your detectors.

You already have the imaging principle, and you know how to do it.

You already have the three-element coils (TX, RX1, and RX2).

- - -

OK, off the soapbox.

No hard feelings, I hope. None were intended.

Cheers,

Joe

Great description of the GTI 2500 metal detector. The GTI Series were a great detector release, primarily due to the imaging. And, as (you) a polished GTI 2500 might agree, you would have to learn the imaging features properly, their limitations and when to utilize them. Then and only then could you appreciate the usefulness of that feature. I got so many more silver coins & jewelry, saving much precious time by NOT digging junk, or items which I was not searching for at that time.

Now, as to new technology coming from Garrett......you just wait and see. Garrett had some good home runs with the ACE Series and the AT Series. The introduction of ACE Series package included such options as notching, different programs and decent depth, available at half the price of the current competitors at that time. Did Garrett farm out there production to China? Heck no! There were built in USA by Americans. And, also included an excellent warranty......one of the best! The accessory coils were also readily available upon the new ACE Series release. And at affordable prices.

Next came the AT Series.......again, great options in a metal detector at a decent price. But........what made these machines such a success was that a person could now include water hunting, at an affordable price. Water machines always cost more, and rightfully so, as the chance of a malfunction due to water leakage risk is considerably high! But, Garrett again, made a wonderful package affordable to the masses.

Now what is next in the new line up? I have no direct inside information as to what they are planning. And, anyone who does, won't speak up. However, based on past released lines of metal detectors, I would expect some new equipment, with all the latest technology, lots of wireless, water proofing at a very affordable price to all. And.....inclusive of great warranty and affordable accessories such as search coils, covers, extra rods......etc. I would again expect different models available, to those who specialize in gold, coins, relics and/or water hunting.

Garrett has been producing metal detectors for a very long time! Garrett is responsible for much technology introduced into all metal detectors today.





Now about that imaging........wouldn't it be great to re-introduce it into a new yet to be released line?

Yesterday I took the GTI2500 to an old park.

It's a large circular park. It used to be the "turnaround" terminal for streetcars. Each car would come down a long, straight street and stop in the turnaround area, and guys would literally turn it around to go back the other way. There's another circular park at the other end of the line. That was about 100 years ago.

I've already detected the place several times, and so have other guys. I've come up with Indian Head cents and a V nickel. As it's a modern park now, I've found modern coins also.

But ... there's a lot of trash. Pulltabs, bottle caps, can slaw. I do mean a _lot_ of it.

- - -

OK, now to the point ...

The trash and modern coins are usually 1 to 3 inches down.

Yesterday, I set the GTI2500 "Surface Elimination" to 3 inches. It only detected targets deeper than 3 inches.

Came up with a ladies' antique button with a floral design at 7 inches, and a Wheat Cent at 6 inches. The target ID and image sizing were perfect.

The only "trash" stuff was some deep copper fragments left over from the old construction.

And there were no distractions from trash. Just quiet sweeps, looking for the deeper stuff.

I'll go back there again and sweep for the shallow targets, no problem there. But now I already know I've covered a lot of ground for the deep targets.

Humble opinion, the GTI2500 gets a lot of work done the right way.

Cheers,

Joe

I do know the imaging depended on the construction of the coil. Perhaps there's tweaking needed with the new technology. If it can discern a small vs large targets at depths it's sorely needed.

You got it right there.

The coil on most detectors has two windings: one Transmit winding, and one Receive winding. They make a "cone" pattern in the ground. The pattern is shaped like an ice-cream cone: wide at the top, and narrowing down to a point at the bottom. If you have a large "deep" target, or a small "shallow" target, about the same amount of signal comes back. There isn't any "size" information in the signal, so the user has to take more actions to try to find more "size" information. That means, take wide sweeps back and forth, making an "X" in both directions, and try to figure out what's there.

The coil on the GTI2500 has three windings: one Transmit winding, and two Receive windings. The two Receive windings are of different diameters: one large, and one small. So in effect, the GTI has put two cones into the ground. One cone is large and deep, and the other is small and shallow. The GTI's electronics has two "target" signals coming back -- one coming from the "large and deep" cone, and the other come from the "small and shallow" cone.

So in effect, the GTI can compare the two signals, "large/deep" and "small/shallow", and estimate the target's size and depth.

For sure, the GTI technology has to cost more than a "regular" detector design, both for the enhanced coil and and for the additional circuits processing the signals.

Garrett's challenge would be to convince prospective users that the additional cost of the detector is worth it, for getting the targeting accuracy. You pay more up front for your detector, but then you can dig less junk, and you cover more ground for the kind of targets you're looking for.

I think that would appeal to experienced users, but it's an open question as to whether it would mean anything to newcomers.

Personally, I am ready to buy one tomorrow.

Cheers,

Joe

I always have my eyes peeled for a 2500,, with me its why I do this I was reading about the guy who found the roman hourde I think it was and he had a GTI2500,, plus it was the color of my favorite dirtbike the KX.... why not have one in the collection someday. now as for the large vs small target that's pretty cool because I'm a sucker for digging past the pinpoint depth and struggling to find that coin.
