When hand held metal detectors are mentioned, most people immediately think of something used for security purposes. While the security field does use them extensively to check for hidden metal objects such as guns, knives, and drug-paraphernalia, an increasing number of hobbyists have discovered that hand-held detectors are extremely useful in many treasure hunting-related endeavors as well.
FEATURES
The first feature of the Pocket Probe that becomes apparent after removing it from the shipping box is its overall size. The sensing coil and electronics are built into a single housing which measures only 3-1/4 inches wide by 6-1/4 inches long by 1 inch thick. The entire unit only weighs 8 ounces which makes it well suited for applications where size and weight might be a concern such as when hiking in to a remote location or searching a cramped crawl space in an old house.
The Pocket Probe uses a T-R or transmit receive circuit that allows for fully automatic operation while providing maximum sensitivity at all times. The sensing coil is the same size as the control housing which results in the ability to scan a given area in less time than other types of hand-held detectors. The Pocket Probe is extremely simple to operate. With the unit in one's hand, the small button located on the left hand side is pressed and held. This turns the unit on and no other adjustments are required to begin searching. The Pocket Probe should be held just above the surface being checked to ensure maximum detection depth is obtained. A nice feature of the ON/OFF switch is that when it is released, the detector turns itself off which eliminates having a dead battery when you are miles from the nearest store.
There is a small red indicating light on the face of the detector which comes on when the target is detected. The intensity of the light will also provide the user with an indication of the relative signal strength which helps determine the size and depth of the target.
In addition to the indicating light, the Pocket Probe features a built-in speaker that also provides an audio signal when passing over a target. Next to the ON/OFF switch is a mini headphone plug which accepts the optional earplug offered by the factory on most light weight headphones such as those used on portable radios and CD players. The use of headphones or the earplug is recommended for high noise areas and times when you might not want to attract any undue attention.
The Pocket Probe uses one 9 volt transistor battery which is located in a small compartment on the back of the control housing. Battery life averages 50 to 60 hours, and a ni-cad battery can be used with no loss of performance. The audio response will change from a clear tone to a "warble" when the battery needs to be placed.
FIELD TEST AND USAGE TIPS
Before I actually took the pocket probe into the field, I checked its sensitivity and signal response by passing it across various items such as coins, a nail, jewelry, a mason jar partially filled with coins, and a piece of electrical wire.
For a lightweight, hand-held detector, the depth at which it could detect the different targets was quite impressive. I found that it would even produce a repeatable signal when a coin was passed along the side of the Pocket Probe on edge.
The first site to which I took the Pocket Probe was a nearby school yard. I had also brought along one of my target ID metal detectors and hoped that the Pocket Probe would help me recover targets once they had been located with the other detector.
I began searching near the backstop of the ball field, and quickly received a signal that indicated "DIME" at a depth of one inch. Laying the detector on the ground, I cut a three-sided plug and folded it back. Rather
than using the detector to Pinpoint where the target was, I removed the Pocket Probe from my coin pouch, pressed the button on the side, and passed it over the plug. It produced both an audio and visual signal, and carefully scraping some dirt away revealed a 1967 dime.
The next good signal that I received indicated "PENNY" at just over 6 inches. Pinpointing the target, I cut a plug and then checked both the plug and the hole with the Pocket Probe. Neither produced a signal so I broke some dirt free from the bottom of the hole and placed
it on a piece of cloth. This time when I checked the pile of dirt, the Pocket Probe gave a sharp signal and I quickly found a 1944 wheat penny that had been caked with dirt.
I spent about two hours at this site and found that by using the Pocket Probe in conjunction with the conventional metal detector, pinpointing and recovering targets were considerably easier and quicker than just using the metal detector by itself
Another facet of treasure hunting in which the Pocket Probe excels is searching for lost or hidden valuables inside of older homes. There are literally tens of thousands of homes that were built prior to the 1930s, and some reports have stated that 2 or 3 out of every 5 of these homes contain a hidden cache of some sort.
It may have been some loose coins stashed by the wife for groceries, a small sack of silver dollars put away by the husband as "drinking" or "gambling" money, or a larger container filled with the life savings of a recluse or miser.
In addition to intentionally-hidden caches; there are coins and other artifacts that were lost over the years just waiting for a treasure hunter with a little ingenuity and perseverance to retrieve them.
Before searching any home, even if it appears to have been abandoned for many years, find out who the current owner is and obtain permission to search it. If possible, sign a search agreement with the owner to ensure anything you find will not be taken away after you have recovered it.
The Pocket Probe is the ideal tool to search the interior of a house as it is much more maneuverable than a conventional metal detector. There are several good books on the market that discuss possible hiding spots, however, some of the more productive ones include the following:
1) Around door and window frames.
2) Under baseboards - over the years coins have been pushed under the crack between the baseboard and the floor. The sensitivity of the Pocket Probe will allow you to quickly locate any of these long-lost coins.
3) In back of closets - check for secret compartments.
4) The steps - often treads were removed and valuables hidden in the openings beneath them.
With a little thought and a bit of luck, users of the Pocket Probe just might find some of these valuables that have lain hidden for many years and previous treasure hunters have overlooked.
The Pocket Probe can even be used around the house for such tasks as locating studs, nails, and even electrical wires before cutting into a wall. It is small enough that it can be left in the glove compartment of your car or in the carrying case of your detector to be used whenever the opportunity arises.
SUMMARY
The Garrett Pocket Probe has been designed to provide treasure hunters with a metal detector that is compact and light weight yet sensitive enough to allow it to be used for a wide variety of treasure hunting applications.
The factory offers a durable carrying case for the Pocket Probe along with the optional earplug. Both of these accessories are available directly from Garrett or from your local dealer.
