Garrett Electronics has been a family-run business since Charles Garrett originally founded the company in 1964. The primary goal for the new company established by Charles and Eleanor over their dining table which remains the focus for the company 40 years later was a simple one - "To develop and manufacture the best possible multi-purpose metal detectors based on the most advanced technology available".
My family and I have used many Garrett detectors over the years and as a matter of fact, my first "real" metal detector I bought after using a number of low cost or home built units was a Garrett Hunter BFO which served me and my brother well for years. More recently, my wife's detectors-of-choice have been Garrett GTA's based on their simplicity and performance in the type of hunting she prefers (and since she's found 4 gold coins with them, who can argue with the results!). Having used both the GTA and GTI models around the country for several years, I was interested to see how the new GTP 1350 performed since it appeared to be a cross between the two in terms of features.
The GTP 1350 is the result of considerable research & development time by Garrett's engineering team. Based on feedback from users worldwide as well as Garrett's continual improvement program, the engineers strived to produce a detector that provided features not found on other detectors in its price range yet remained simple to operate.
At first glance the GTP 1350 looks like a GTA or even a GTI 1500 based on its control housing. Not wanting to change a proven design, the 1350 utilizes the same shaft / control housing that Garrett has fine tuned over time and has proven to be ergonomically well-suited for users of all sizes.
Before getting into the search modes and other features of the GTP 1350, the unique target sizing feature deserves to be covered. Several years ago Garrett introduced target imaging on their GTI-series which provided users with target information not found on any other detector. For those of you that are not familiar with the target sizing / imaging system on the GTI series, the benefit of providing this piece of information in addition to the ID and depth found on many detectors today is worth discussing. Target ID information is based on the conductivity of targets so there are times when a large (or small) piece of trash will provide a solid signal indicating the detected target is a coin or some other "keeper". A good example is a soda can on the beach which typically reads like a coin. After digging 12"+ to recover a few of these, its easy to get frustrated. Well, by combining the target ID with the target size, you can determine if a target is worth recovering. In the case of the soda can, even though you will get a solid coin indication, the imaging or sizing feature will show you that the target is larger than a coin and you can keep searching for that next GOOD target. It is a feature that has proven itself to me numerous times coin hunting, beach hunting and relic hunting with the GTI 1500 & 2500.
The GTP or Graphic Target Profiling gets its name from its ability to not only display target ID and depth via the LCD display but also target size; however, in a slightly different form as displayed on the GTI models. There are three target sizes that will be indicated when the profiling search mode is activated - small, medium and large. Coin-sized objects register as SMALL, targets up to 4" in diameter register as MEDIUM and bigger targets will read as LARGE. NOTE: While these indications are sweep-distance dependent (but independent of sweep speed), it becomes second nature after a short time in the field.
A unique feature of the GTP 1350 is that it provides target sizing or profiling with ANY search coil unlike the GTI series which requires special Imaging coils to provide that information. Not only does this save money when purchasing additional coils but it allows you to use any GTA coil you may have such as the Crossfire II or DD coils while providing profiling data via the LCD screen.
Another feature which further enhances the 1350's versatility is the ability to turn Profiling ON or OFF. As covered in the instruction manual, the combinations of Profiling and Tone ID will produce different audio responses to targets. Users can easily select the combination that best suits the conditions of the specific area they are hunting and their personal preferences.
Once the GTP is turned on, all adjustments can be easily made through the MENU option and the touchpads on on the face plate of the control housing. The options include:
Tone and Volume
Battery Type (rechargeable or regular)
The GTP has five independent discriminate search modes: Coins, Jewelry, Relics, Zero and Custom. The first four are preset by the factory, but all five are adjustable. Adjustments made to the Custom mode are retained when the detector is turned off allowing users to tweak the GTP to fit their specific needs without any complicated programming.
The discrimination circuitry allows one to selectively accept or reject specific targets without any loss of sensitivity as typically occurs on most other non-notch detectors and aids in minimizing the amount of trash one recovers from a trashy site. Selecting what targets you want to accept or reject is extremely easy and is one of the most highly-rated features of the Garrett GTA & GTI series by their owners (and is now found on the GTP). The GTP 1350 is powered by eight AA batteries which will provide approximately 25 hours of use. Nicad batteries can be used with no loss of performance. A nice feature incorporated on the GTP is the removable battery pack initially introduced on the GTA line. If weight is a factor, simply slide the pack off the armrest and clip it to your belt to drop the weight of the detector to less than 2.75 pounds!
After spending some time in my test garden getting used to the GTP's response to known targets & operations of the Profiling circuitry, I visited a few local schools and parks to see how it performed in the field. Combining the notch discrimination feature along with the visual target ID, depth & target size indications, I recovered close to 100 coins with virtually none of the trash typically found at these types of sites.
Early one Saturday morning I met up with three fellow club members and headed towards the center of the state (SC) for some coin hunting as well as hoping to find a Confederate campsite. Temperatures were already in the 90's by 9AM as we pulled into the first site - a house that dated back to the 1840's. Chuck Smith was the first one to come up with a keeper - an 1875 Seated Dime - with the Garrett GTI 2500 he was using. A few minutes later I heard the unmistakable Bell-Tone audio indicating a probable coin and pressed the PINPOINT touchpad to activate the profiling circuitry. The display indicated "DIME" and a SMALL target size which was a positive sign. Cutting a plug, I recovered a nice 1939 Mercury dime from just over 6 inches (OK, not quite as impressive as Chuck's find but it was silver!), Over the next 45 minutes I picked up several more coins and some yet-to-be-identified artifacts at depths up to 9 inches deep. The most noticeable aspect of the GTP 1350 was its stability and lack of false signals which occur on many detectors when the coil is bumped against roots, stubble grass or rocks. The new "Rhino Tough 7"x10" PROformance" elliptical epoxy coil that comes with the GTP performed as Garrett claimed it would and eliminated the need to continually check if a "beep" was really a target or simply a false signal.
On the way home, we stopped off in several small towns to do some yard hunting. It was tough to stay motivated after spending all day in the SC heat & humidity but coins turned up with enough frequency to retain our interest. A number of coins and other "goodies" were added to my pouch thanks to the GTP 1350 and considering how dry the ground had been, the GTP had performed well in terms of detection depth and target ID accuracy.
Just before this report was due, I had the opportunity to hunt some of the beaches near Charleston, SC with my family. Due to the wave action, sand had been brought in so any finds would be recently lost items. My son Paul & I started hunting along the edge of the dunes and immediately began recovering coins from depths of up to 7". As we walked towards the wet sand area we began to get some falsing so I went into the Options Menu and activated the Salt Elimination circuit. This change, combined with a slight reduction in Sensitivity resulted in a noticeable improvement in the GTP's stability and allowed us to pick up several more coins as far down as the surf line. Some "beeps" required rechecking; however, for the most part actual targets were easily discernible from the occasional false signal.
I used the optional 10"x14" DD coil at some sites that contained extremely mineralized ground which gave virtually any detector a hard time in terms of detection depth and overall stability. The difference between the standard coil and the DD coil was quite noticeable and it allowed me to recover targets that would have otherwise remained undetected. Just a point to keep in mind - if you find yourself experiencing overload conditions in more than an isolated spot or two (resulting from ground conditions rather than large trash targets), the DD coil will open up areas that most of the competition has probably avoided in the past.
The new GTP 1350 offers treasure hunters an easy-to-use detector with features not found on any other detector in its price range. Garrett has always instructed his engineering staff to provide performance while keeping the detector SIMPLE to operate and the GTP is no exception. All of the adjustments can be made with a minimal number of keystrokes and no complicated programming is required to obtain maximum in-field performance. Additional details & field test results are available in the field test section of the Lost Treasure web site (http://www.LostTreasure.com).
The GTP 1350 lists for $699.95 and comes with a 5-year warranty to commemorate Garrett's 40th anniversary. Several optional search coils are available in addition to the new 7"x10" PROformance coil to further expand the GTP's versatility including a 4.5", 8.5" or 12.5" Crossfire II concentric coil and the 10"x14" Double-D coil.
