Intermediate Level or “Journeyman” Detectors

Garrett GTI 2500

Although most of you know already that I’m no great fan of multi-purpose detectors posing as gold or nugget-hunting/shooting machines, I do believe that Garrett’s GTI 2500 ($940.00-$1400.00) is one multi machine that has the potential to deliver the goods when it comes to finding nuggets and gold ore. And, for those of us who can’t afford 3 or 4 separate machines tailored for specific functions (nugget hunting, coins, relics, underwater hunting, etc.) the GTI 2500 provides a reasonable solution.

Graphic Target Imaging

Unlike most other comparable metal detectors that can only determine a target’s depth and metal composition, the GTI 2500 employs Garrett's patented Graphic Target Imaging (GTI) technology which allows you to "see" targets buried beneath your feet. In this context “seeing” means that the GTI 2500 can reveal a target's actual size and true depth via a unique graphic display that is easy to use and decipher.

Gold Concentrators

This type of specific information can prove invaluable out in the field in certain treasure hunting contexts, especially when you find yourself scratching your head trying to determine the type and/or size of a given target. However, this graphic analyzer may not have quite the same significance or usefulness to hard-core nugget hunters who depend more on a trained ear and loads of experience to get the gold.

One Potential Drawback

The GTI 2500’s operation is based on Garrett’s Power Master digital signal processing chip and a 9 1/2" deep-imaging search coil. The entire unit operates at the relatively low frequency of just 7.2 kHz, atypical for most “hot” nugget machines which usually operate at the very high frequency (VHF) or ultra-high frequency (UHF) ranges. Thus, one potential drawback for the GTI's capability as a nugget hunting machine is that it may not be able to “see” some of those tinier pieces of placer gold that a higher frequency machine (e.g., Fisher’s Gold Bug 2) would.

Major Features

Here are some major features of the GTI 2500:

• Size and depth matrix
• 24-notch discrimination
• Sharp audio target response
• Ramrod stem with armrest
• Battery pack hip mount (Note: this can really save wear and tear on your arm. J.R.)
• Waterproof elastomeric control touch pad
• Automatic pinpointing (non motion)
• True depth reading
• Six operating modes (non motion/all metal, coins, jewelry, relics, zero, and custom)

So there you have it my friends. If you’re a Garrett fan or user (which I have been for many years) the GTI 2500 may be just what the treasure doctor ordered.

Best of luck out there.

  1. The GTI 2500 hits gold targets very well better than my Minelab Eureka Gold, Garrett just makes a better detector, it just has so many usefull features, esp if you are an older hunter like myself, I really like the voice, I own an older unit, but for low light conditions the 2500 tells you what the target is just by a push of a button, if you learn this detector it has more features than any detector on the market today and it goes deeper than any VLF unit in almetal mode, a real keeper!!

  2. Thanks much for providing your insights on the 2500. I appreciate the info and your comments. Best! J.R.
