QUICK START GUIDE FOR YOUR NEW TREASURE HUNTER METAL DETECTOR.

CONGRATULATIONS ON YOUR NEW TREASURE HUNTER METAL DETECTOR, YOU HAVE CHOSEN ON OF THE FINEST METAL DETECTORS AVAILABLE IN THE USA AND UK TODAY.  BELOW ARE SOME OF THE "PITFALLS" AND WAYS TO UNDERSTAND YOUR TREASURE HUNTER METAL DETECTOR BETTER.

Be sure you are not using it indoors because light bulbs, microwaves, cell phones, cordless phones and many other house hold items can cause interference with the units magnetic field because these items have a electromagnetic field of there own causing the metal detector  to "churp" or beep erratically.
Many users put a quarter on the floor of there house and find that they receive false readings.  This is due to the electrical lines under the floor (metal and magnetic field produced), nails in the floor crossing the magnetic field of the metal detectors search coil.
Do not use your new Treasure Hunter around power lines or on concrete, concrete has rebar in it, a metal that will cause the detector to beep.  Also keep the detector clear of chairs, walls and tables as these objects can also contain certain metals (even the side of the coil can give a reading, which is why the part that attaches the coil is made of plastic).
 
In order to test your unit, have someone hold the unit no less than 3 feet off of the ground, take a nickel  in your hand and move it in a constant motion across the search coil, again, do this outside the house and outside of any possible interference.  Be sure that the quarter  is flat with the search coil, which is how your new treasure hunter metal detector is programmed to detect those objects.  If an object, such as a quarter, is moved over the search coil in a position other than flat, it can cause false readings as well, the motion must be constant, this is a fell that will be developed over time.  Treasure Hunter has given your metal detector a powerful program that allows the detector to “see” or detect and object in a certain position, the detector will detect that object in its flat position.  In the field, that is how the object will be found 99% of the time.

Size, shape and oxidation can cause the processors program to read certain ways, or even read an object incorrect.  Recently buried coins might not respond the same as coins buried for a long period of time because of oxidation.
Some nails, nuts, bolts and other iron objects oxidize and create a "halo" effect.  A halo effect is caused by a mixture of naturally occurring elements in the ground and the oxidation created by different metals.  Because of the metal mixtures, targets signals might not be n a "fixed" position that the computer program given your detector is programmed to "see" or detect that kind or shape item.

(For Digital Treasure Hunter LCD models only) When using your treasure hunter metal detector to identify objects such as gold, or silver, use the strip across the top/bottom, depending on the unit you are using (notice this feature is for digital LCD treasure hunter metal detectors only)

Sample strip below:

Notice they will be different depending on the model you have.  If you do not have a LCD readout, such as the navigator Plus or the Voyager, you will not have this strip.

You will notice that the strip goes from iron to gold to silver.  you may also note that there is a coin listing on that strip as well, however, the coin strip is only a size indicator, do not use the readings on the LCD at this point except for a reference between the iron, gold and silver. 
Gold can register anywhere on the left side depending on its size and purity.  for example, when reading a large watch, the detectors program will read nail, penny, quarter, etc., that is because the program of the unit is reading the gold, silver, iron and other metals in that object, that is why the indicator will jump around sporadically.  The same thing applies with a gold ring.  A gold ring will read generally between the iron and gold depending on how pure the gold is and what item is mixed with the gold to make it (for example 14 k) the purity it is, 24k being solid gold and 14k being the less amount of gold mixed with other metals (some precise, some not).  The largest reading for gold will be .05 to .25 in the correct iron to silver strip at the top within the gold.  The reading of the LCD has little to do with material, but will give some idea to size, the kind of material by the way the detector behaves will be identified when the user is an experienced user.

The pinpoint is the 2 lines you see come close together at the bottom of the LCD read out. (for Treasure Hunter metal detectors that possess this feature only) ,   The closer the lines become, the more on top, or on target you are.
When you find the object, it is a good idea to step right and swipe the coil in an "x" motion. Right to left (south to west), and then right to left (north to east).  This will help in pinpointing as well.
Sweep the detectors search coil holding the search coil level (do not use like a pendulum raising at the end of the stroke), use many angels to better pinpoint the target.

 
When in the field, swipe the coil in a constant motion, be sure that the coil is swinging level (see manual).  Although this seems simple enough, this is a feel that takes some time to develop.

 
Be sure you are detecting an object of one kind of metal, for example, a watch or a piece of gold jewelry contains many kinds of metals generally.  The detector is programmed to detect certain kinds of metals, but when a piece of metal contains several kinds, it confuses the detector when "sniffing" the metals at one time.  A penny made before 1982 is made of copper, a penny made after 1982 is made of zinc (a less expensive metal) and will read different for each of the post and pre 1982 penny's.
 
Be sure the discrimination knob is not turned all the way up to display all objects in the LCD (only on Treasure Hunter models that have this feature), if every metal is being discriminated, it will not beep even if it is moved over metal.  That is the job of the discriminator.  It is better not to use this feature until you have become familiar with the machine and have used it extensively in the field, not just a few “test” preformed.
 
Automatic Ground balance:

Be sure, if you are receiving false readings, re adjust the ground balance, turn the unit off, turn it on again (in a place with no interference and far from the house) holding the coil 3-4 inches from the ground so the detector can ground balance itself.  Even with the ground balance function, if the soil is highly mineralized, it is difficult for any self ground balancing machine to balance itself.
It is very important to swing the coil parallel, do not lift the search coil at the end of the swing like a pendulum.  Keep the coil in constant and consistent motion the whole time as you sweep the ground.  The z-processor is measuring the soils content and averaging its calculation over time consistent coil speed at a constant height helps the z-processor in your detector scan accurately and discriminate against the earths naturally occurring minerals.  Remember to adjust the detectors sensitivity when beeping "out of control".  Having sensitivity levels up will give beeping sounds no matter what or the position of the detector.

BELOW IS FOR TREASURE HUNTER METAL DETECTORS WITH SPIDER COILS ONLY:

The outside loop of the spider coil creates a magnetic field.  The inside loop of the spider coil gives the reading of the LCD.  Different characteristics of metals, size of objects disrupt or reflect the magnetic field given off by the outer ring.
The inner ring (the inside loop) detects the LCD reading.  The object must pass over the range of the smaller inner ring of the coil.  Treasure Hunter metal detectors with disk coils work the same way, but the inside loop is impossible to see with disk coils.

Because your detector is extremely sensitive, trash-induced signals and other sources of interference might cause signals that seem confusing.  The key to handling these types of signals is to dig for only those targets that generate a strong, repeatable signal.  As you sweep the search coil back and forth over the ground (level), learn to recognize the difference between signals that occur at random and signals that are stable and repeatable.
To reduce false signals when searching very trashy ground, scan only a small area at a time using slow, short, overlapping sweeps.

 

Detection Hints that will effect readings:

1. Always check the batteries; only use a new quality alkaline batteries (Very Important).
2. The angle at which the object is positioned in the ground.

3. Depth of the object
4. The amounts of iron (or other metals) combined in the target.
5. Size, shape and oxidation of the target object.

6. The search coil should be level; picking up the search coil at the end of a swing will produce false readings.

7. Light bulbs, microwaves, cell phones, cordless phones and many other house hold items can cause interference with the units magnetic field causing the metal detector  to "chirp" or beep erratically.  If this happens, move to an area that does not have this interference, or eliminate the item in the area by turning it off until the object that is interfering is identified.
