SUGGESTIONS FOR OPTIMIZING YOUR DETECTION EXPERIENCE

With my Deepers I am getting the deeply buried older and more valuable targets!  I have a lot of faith in this powerful and reliable treasure hunting tool!

A word about the height of the detector coil:

Maintaining proper height of the coil from the ground is very important.  Using a VLF detector with the coil too close to the ground will produce erratic and unstable operation signaled by excessive false signals and audio tones where there is no target.  This worsens if the ground is exceptionally mineralized or humid.  When using a pulse induction detector it is important to tune the coil while holding it approximately 4 inches from the ground and maintain that height throughout the hunt.  This is easily and quickly learned with a little practice and maximizes the depth and minimizes false signals.  A good distance to maintain on even ground is about 4 inches, trying not to vary too much up or down.  On uneven or rough ground the coil can be operated over rocks and rubble at about 6 inches.  The important thing to remember is to maintain the height from the ground that you used to tune the detector.  Another fantastic technological breakthrough from our Deepers engineers and found on the Deepers MF Multi Frequencies is the AT (auto tune function) which allows the detectorist to vary the detector coil height depending on changing ground conditions without having to retune the detector.  The detector automatically senses the change in coil height and ground conditions and auto tunes the detector to the original setting in an instant. 

Detecting around oxidized iron objects (large rusty iron objects)

Quite often during detecting or prospecting we find an area that causes erratic and intense responses from the detector and indicates a very large metallic object under the coil.  When using a VLF detector, it is almost impossible discriminate this out and one is obligated to excavate in order to see the target that produced the response.  In a lot of these cases we find the presence of oxidized iron, a rusty old container, a chain, a roll of wire, or a piece of oxidized scrap metal. Why does this phenomenon occur? The answer is simple; the oxidation spreads out from the target and creates a halo in the ground that makes the target seem far bigger than it really is to the detector.  This tricks the detector and as a result the detector does not discriminate the iron out.   When using a Deepers metal detector the interaction of metal and oxidization is completely analyzed by the advanced circuitry and the target can either be easily pin pointed for recovery or if desired completely rejected using the adjustable REJECT function to ignore iron in the first 12 to 20 inches of the surface.  When passing over iron in the REJECT zone, the red REJECT LED will illuminate signaling to you that the target can be passed up.  Remember that Deepers MF can locate a target at a depth up to 4 ft with just the PLANAR MONO coil and more than 12 feet  depth with the square detection coil that measure 40 x 40 inches…you don’t miss anything.    

How to conveniently adjust the sensitivity of your detector (SENSI knob)

Sensitivity is the basic detector adjustment that must be understood and taken into account by the detectorist.  Some detectors do not have this capability and the ones that do are very misunderstood by the user.  Most confuse increased sensitivity with increased depth but fail to understand that depending upon ground conditions a reduction in sensitivity will allow the signal to go deeper into the ground as a higher sensitivity causes the signal to reflect back much like using high beam headlights in a fog bank, lower the intensity of the beam to low beam and your light penetrates deeper into the fog.  The same concept applies to metal detector sensitivity as it applies to highly mineralized ground.  The well made VLF detectors incorporate a GROUND balancing feature that helps to overcome stability issues and is comparable to sensitivity adjustment.

On the Deepers detector we find the SENSI knob (for sensitivity). With the knob set on the red dot (at 11 o’clock position) the detector is at maximum sensitivity.  Turning the knob counter clockwise reduces the sensitivity and the further we turn the less the sensitivity.  When detecting over neutral or non mineralized ground we can use the detector at maximum sensitivity (SENSI knob on red dot).  If we notice erratic or unstable operation in the case of mineralized ground then simply turn the SENSI knob to the left or counter clockwise until the operation stabilizes.  Slight mineralization can be stabilized normally at the 9 o’clock position (SENSI knob at 9 o’clock).  If the terrain is very reactive (highly mineralized) we should turn the SENSI knob closer to 6 or 7 o’clock position. (SENSI knob adjusted to 6 or 7 o’clock position) Adjusted this way your Deepers is able to transmit the signal at maximum depth and detect the deepest of targets.  You can see how reducing the sensitivity based on ground conditions can actually improve detection depth.     

What to do in the presence of mineralized ground?  Our solution!

In order to meet the needs of our clients that prospect or treasure hunt in highly mineralized ground, we have incorporated into the new Deepers MF a system that permits the usage of the PLANAR DD Litz winding coils, the newest and most advanced in detecting technology.  These coils act like a filter that cleans up interference from mineralized ground or ferrous (iron) objects.  This allows smooth and stable operation of the detector and extreme depth capabilities on gold and silver.  For example: We conducted a test using a small leather bag with a mixture of 15 gold, silver, and bronze coins buried in the highly mineralized soil of our test bed it was easily detected at a depth of more than 28 inches using our new Deepers MF with the Planar DD Litz coil.  (The DD mono coil was unable to detect it….Litz technology solved the problem)  Try that with your high end expensive VLF detector!

The standard target for testing a pulse detector is 14 grams of non-ferrous metal.  The Deepers MF Multi Frequency detects it with great ease at a depth of 28 inches with the MONO PLANAR coil in normal ground conditions; in mineralized terrain it will detect the target from 18/20 inches. With the PLANAR DD Litz coil you can detect this same target at a depth of 22/24 inches in hard highly mineralized ground, an improvement of 20%;   This performance is unparalleled by other Pulse Induction PI detectors on the market and we won’t even consider the VLF detectors that can only detect the same target at a depth of 7 inches in difficult terrain.

Again we want to remind you of the technological breakthrough of our (REJET) capability that allows for elimination of iron objects up to the first 20 inches of detection depth and let us not forget our AT feature, the Auto Tune system that automatically maintains your settings over changing ground conditions.  …Yes the Deepers MF is truly the vanguard of detectors, the standard by which all others should be judged. 

A variety of 15 gold, silver, and copper coins…used for testing

IMPORTANT TO KNOW WHEN DETECTING: “Sweep” the ground (coil swing) by moving the coil from left to right while maintaining the coil at least 4 inches above ground.  Advance slowly, about 20 inches each time you move forward to thoroughly cover the ground.  Be careful not to lift the coil at the end of the swing.  Keep it steady throughout and maintain constant height from the ground.  Always keep the coil parallel to the ground and at the height where you tuned the detector to the ground conditions at the beginning of your search.  This is the secret for maintaining a stable operation and in recognizing a signal that indicates the presence of a target.   In rough or rocky terrain or where there are trees or shrubs the coil of choice is the Hypersensitive coil by Deepers.   This coil sends out a wide adjustable signal that can detect targets in the periphery of the coil and does not have to be exactly over the target to get a signal.  It can pick them up from the side.   

Some Final Words of Advice: Search around rocks, groups of trees, mountainous places, ruins, lake shores, forests, old mines, wells, caverns or any other place where if you had to hide something and find it later without forgetting the place.  Put yourself in the mind of someone needing to hide gold, silver or other treasures.  Go over places where other detectorists have had success with their detectors…everything below the level they reached is open for you to discover.  Relic hunters, those hunted out fields are now virgin territory, hunted out beaches just got a new breath of life breathed into them.  Gold is where you find it and more importantly where it has already been found.  Go to the places where others have found nuggets with their detectors let the Deepers MF surprise and please you with its extreme depth capability.  Thousands of hidden treasures that are waiting to be brought to light.
