Garrett Electronics is a name that to many is synonymous with searching for and finding lost treasure. For more than 30 years, owner and founder Charles Garrett and his staff have worked to develop the best metal detecting equipment possible for treasure hunters worldwide. Based on the reports received by the factory on a regular basis, this equipment has helped allow its customers to be extremely successful in their searches. I have been an avid Garrett user for a number of years and anxiously awaited the arrival of the newest addition, the GTI 2000 Deepseeker.
Let me start out by saying that while the physical appearance of the GTI 2000 may seem somewhat similar to the GTA series, many of the GTI 2000's features are not found on any other metal detector currently on the market. As with other Garrett models, the GTI 2000 is simple enough so even a novice can take it out and be successful yet powerful and versatile enough to satisfy even the most demanding professional.
Garrett's engineers were intent on designing a metal detector that was not simply just repackaging something that was currently on the market. Given a clean slate to start with by Charles Garrett, Bob Podhrasky and others on the design team took a look at what treasure hunters had said they wanted in a detector.
Realizing that many of the features found on other models in the Garrett line had proven themselves in the field, they started by incorporating the best each model had to offer in the new GTI 2000. These included surface-mount technology to minimize overall size and weight, the highly effective notch discrimination system, the comfortable design of the GTA-series, Garrett's unique TreasureTalk function, and easily accessible touch pad controls.
The first thing you notice when looking at the GTI 2000's control housing is a second display area below the familiar target ID-depth reading LCD display. This is one of the most revolutionary features found on the GTI and is called TreasureVision, which lets you identify buried targets with a higher degree of accuracy than previously possible.
In addition to providing a probable target ID on the upper display (nickel, foil, penny, pull tab, quarter, etc.), the GTI's TreasureVision circuit will provide users with an indication of both the object's size and depth.
As users of target ID detectors often discover, a large object such as an aluminum can will read out like a coin and small shreds of metal tend to read like a nickel or gold ring. So, strictly relying on a target ID indication will result in a fair amount of extra and often unnecessary digging. Designated as A-, B-, G, Dand E-size targets on the Treasure Vision imaging grid, this information will prove invaluable to the user.
- Size A: Targets smaller than coins including small bits or iron and foil.
- Size B: All U.S. coins and most rings.
- Size C: Targets larger than coins yet smaller than 12-ounce cans including large class rings, screwcaps, bottlecaps, whole pull-tabs and smaller relics.
- Size D: Targets similar in size to a 12-ounce can.
- Size E: Targets larger than a 12ounce can such as artillery shells, caches and other large relics.
By combining the indications provided by the GTI's dual displays, you can achieve a much more precise level of accuracy in identifying objects before you dig. For example, on other detectors, even those with target ID capability, you will miss any gold ring that registers the same as a pulltab unless you choose to recover each one.
In many heavy traffic areas such as parks and schools, this would not be feasible. Now, even though the two targets would produce the same target ID on the upper display, the TreasureVision imaging grid would clearly show that there was a difference between the two targets.
This unique feature will greatly increase the number of good targets you will recover in the field, no matter what type of target you are searching for. Additionally, if the TreasureVision circuitry can't accurately interpret the signal received, it displays a series of rings which engineers have called the cone display. This can occur if the target is either too small or deep to identify accurately or if the coil was not centered over the target -just another feature which helps ensure the user is given as much information as possible to accurately identify a target before attempting to recover it.
In addition to those described above, the GTI also includes the following modes and features - all easily adjustable through the convenient touchpads found on the face of the control housing.
- Sensitivity Audio Threshold, Tone and Volume - Quickly customize the GTI's response to your specific preferences.
- Operating Frequency - Great for eliminating interference caused by other detectors or nearby electrical sources.
- Surface Elimination - Lets you ignore shallow, newer targets at depths from 0 to 4 inches while still detecting the deeper, more valuable targets. This is most useful when you have limited time to hunt an area.
- Battery Type - Select either regular or ni-cad so the battery strength indication accurately displays the current battery condition.
- Salt Elimination - Another GTI-exclusive feature, eliminates the interference caused by wet salt conditions.
- Belltone and Bi-Level audio signals - Provides additional information to aid in identifying targets.
- TreasureTalk - A computer voice to talk back to you ' helping you make adjustments and identify targets
- Auto Track - Automatically adjusts the GTI's ground balance setting at one of three different selectable speeds as ground conditions change.
- Manual Ground Balance -Lets you override the Auto Track feature for specific applications such as electronic prospecting.
The GTI has five independent discriminate search modes: Coins, Jewelry, Relics, Zero and Custom. The first four are preset by the factory, but all five are ad unstable. The GTI also includes a true All-Metal search mode which produces detection depth that must be seen to be believed.
Rather than using the Crossfire coils found on the other models in the Garrett line, the GTI's project team developed an entirely new coil to maximize the accuracy and performance afforded by the TreasureVision circuitry. Measuring 9 1/2 inches across and open in the center, it is extremely light.
It is powered by eight AA batteries, will provide between 20 and 30 hours of use. Ni-cads can be used with no loss of performance. A nice feature incorporated on the GTI is the removable battery pack found on the GTA line. If weight is a factor, simply slide the pack off the armrest and clip it to your belt.
I opted to take the GTI 2000 to a well-hunted Civil War campsite located just north of Atlanta. The ground consisted of mineralized red clay which challenges most detectors used here. Pickings here were few and far between and what remained was either extremely deep or masked by iron trash spread across the site.
Selecting the factory-preset Relics mode, I began hunting near the center of the old camp. I was immediately impressed at how quiet the GTI was even with the sensitivity set at 75 percent. I did not get any false signals even when the coil was bumped against rocks and tree roots, a problem I've experienced on many other detectors. Near a fall of dead trees, the GTI produced a solid signal that registered in the Pulltab region - typically a good sign when relic hunting.
Checking the TreasureVision imaging screen, it showed a C-size target at approximately eight inches. Sure enough, careful digging produced a dropped Enfield bullet at just under eight inches. During the next 2 hours I covered a small portion of the camp and was quite satisfied with my success. Seven bullets, the brass tip of a sword scabbard, a lead poker chip made from a bullet and a Civil War-vintage horseshoe had been recovered from depths ranging from six to 15 inches - not bad from a site that most local hunters had long-since written off as worked out.
I had also found three percussion caps the size of .22-caliber shell casings at depths of 4-5 inches which demonstrated that even with a 9 1/2inch coil, the GTI was still capable of detecting very small targets.
More than what I had found, I was surprised at what I had not found no rusted barbed wire, old nails or other small iron trash that we usually found here. The GTI's discrimination circuitry in conjunction with the TreasureVision feature let me identify a number of good targets among the junk with a high degree of accuracy. One thing that prospective buyers need to keep in mind - the TreasureVision imaging system is unique and does take some time getting used to before you realize the full potential it has to offer.
The next site I went to was an area on a nearby lake that was popular with the jet-skiers in the summer. Since the lake is drawn down some 15 - 20 feet each fall for flood control, the shoreline was exposed and awaiting a detector to find out what had been lost.
Hoping to find some jewelry, I selected the Jewelry mode and made a slight adjustment to the factory settings. I have found that some small 14kt white gold rings (such as engagement rings with diamonds) can readjust below the lowest notch accepted in this mode. By accepting one more notch on the low end of the scale, you will pick up a few more pieces of foil, but you also improve your odds of finding one of these beauties.
Again, I found the combination of the target ID and TreasureVision displays let me accurately identify almost every target before I recovered it. For the purpose of this field test, I recovered every target - even those I knew were junk. Nearly every pulltab registered as C-sized targets. Nickels, even though they registered in the same area on the meter, registered as B-sized targets. The cone indication proved helpful in letting me know that the target was not being accurately analyzed and that the indications were suspect. By taking a moment to center the coil over the target, this cone disappeared and an accurate picture of the target was easily obtained.
Several targets such as spark plugs, tools, a watch and a Matchbox car that my son Paul quickly appropriated were found at depths exceeding 10 inches. Coins registered accurately every time, even those that were right next to a piece of trash. After a few hours at this site I headed home with a pouch full of coins, a small I OKT gold ring and a handful of car keys.
Taking the GTI 2000 to other sites in both Georgia and South Carolina produced similar results. Smooth performance, highly accurate target ID, good balance even after several hours in the field and above-average detection depth allowed me to bring home a nice assortment of coins, relics and jewelry from the sites I visited.
Having a metal detector that identifies targets by name, relative size and depth is a great leap forward in metal detector design. The combination of features found on the GTI 2000 will quite likely change the way treasure hunters look at target ID detectors in the future.
