The Teknetics 9000 is a remarkably advanced and precision engineered metal detector. It features the very latest advancements in metal detector technology.

The amazing "Coincomputer" 9000 incorporates a unique and ultramodern LCD readout. The crystal display provides a truly phenomenal wealth of information to the TH'er. Just a simple glance at the display after a few sweeps over the target, will tell you the depth of the find and indicate with a great deal of accuracy what the find may be.

In addition, the display indicates the mode of operation and the battery condition.

SURVEYING - Iron stakes established in earlier surveys can be more easily located, especially when overgrown with weeds and covered with debris.

LOGGERS - Nails, insulators, etc., can be easily located before costly damage to an expensive blade and eliminate danger to the operator.

LAW ENFORCEMENT - Using a metal detector to systematically sweep suspected areas for discarded weapons or stolen property is a common practice today.

PIPES AND CABLES - Before causing damage, a metal locator can be used to determine the location of buried pipes and cables prior to digging.

These are just a few of the many possibilities. Areas to search are limited only by your imagination!


Metal detectors are used to locate unseen metallic objects. Such desirable objects include coins, rings, watches, pistols, rifles, relics, etc... Metal detectors will not sense nonmetallic objects such as wood, paper, plastics, or cloth.

The following is a list of uses, but is not limited to these uses exclusively.

COINSHOOTING - A hobby devoted to locating coins in parks, school yards, beaches and other areas where the public is likely to lose money. Some specialize in only digging on week signals increasing the likelihood of finding older, more valuable coins that are usually silver.

RELIC HUNTING - Areas involved in past wars, such as the civil war, Indian campaigns, etc., provide many articles from the past such as cannon balls, mini balls, shells, guns, medals, swords, uniform buttons, knives, etc. Other areas to locate articles of history would include old mining towns and areas occupied by early settlers.

PROSPECTING - Searching washes and gullies or old tailings from mines has often revealed nuggets of gold. From time to time even very large nuggets weighing many ounces are reported being found with metal detectors.

BEACH COMBING - Along beaches visited by people everywhere are to be found coins, watches, rings, bracelets, portable radios, etc. And the digging is easy!


Carefully unpack your detector and check to see that you have all the parts shown.

Assembly the detector by placing the lower rod into the upper rod. Wrap the cable around the rod and connect to the loop plug on the case as shown.

Note: At this time you may need to charge the batteries.


Your new Teknetics detector is equipped with factory installed rechargeable Nickel Cadmium batteries which will save many hundreds of dollars in battery purchases as they may be recharged as many as a thousand times or more.

The batteries will require charging for a period of 14 to 16 hours to bring them to full capacity, as they are shipped in the unit only partially charged. It is not necessary to remove the batteries to recharge them. Simply plug the charger cable into the charger socket on the rear of the instrument and plug the charger into an electrical outlet. Once charged, a minimum of seven hours continuous use can be expected.

Nickel Cadmium batteries can develop a memory pattern limiting their available capacity. If they are used in the instrument, for example, for two hours each time and then recharged, the capacity will be reduced to this amount. Should this happen, recharge the batteries and use the instrument until it will no longer operate and then recharge.

There are two charge modes available. For normal charging set the POWER switch to "Norm". If the batteries are completely discharged, 14 hours of charge time is required to fully charge. For a partial charge a good rule of thumb is two hours charge time for each hour of use.

The second mode of charging is for storage. Once the cells have been fully charged, the Power switch can be set to the 'Store" position. In this mode, the unit will receive a small "Trickle" charge that will keep the batteries at full charge. This way the instrument is ready to use at all times with full capacity available.

The "store" charge is intended for short term storage and should be used no longer than two to three months at a time.


Fourteen (14) 1 1/2 volt AA Penlight Alkaline batteries may be used instead of the NiCad supplied if they are in need of charging and time is not available to wait.

Remove the compartment doors on the bottom of the case and remove the cells being sure to store them so they will not short. Install the Alkaline cells according to the legend for + and -.

CAUTION: DO NOT CONNECT THE CHARGER TO THE INSTRUMENT WITH ANY BATTERIES INSTALLED EXCEPT NiCads. There is danger of explosion which may result in not only damage to the instrument; but also personal injury.


To check the condition of the batteries installed in the detector, turn the "POWER" switch to "ON" and the "Batt. Ck/A.T.I" switch to "A" Batt for the "A" batteries, and to "B" batt for the "B" batteries.

Fully Charged batteries will read full scale on the meter. After the first few minutes of operation, Nl-Cads wlll drop to approximately 70 on the meter scale and remain at that level for the duration of the charge. 1.5 Volt Penlight Batteries Alkalines) wlll show a gradual decline in voltage during their operating life.

Recharge your NiCads or replace your 11/2 volt cells when the batteries read in the RED zones.


Threshold Tone - Barely audible tone set by the "TUNER" control to achieve the best sensitivity to a metal object.

G.B. - Abbreviated term for Ground Balance. Ground balance is achieved by adjusting the "GND BALANCE" control for a neutral response to the mineral content in the ground.

G.B. Disc - Abbreviated term for Ground Balance Discriminate. This mode al adjusts both ground neutralization and selective discrimination at the same time.

G.B. MAX. - Abbreviated term for Ground Balance Maximum. This mode is the same as the GB Mode but with increased sensitivity.

T.R. DISC. - Abbreviated term for Transmit Receive Discriminate. This is a non-ground neutralizing mode of discrimination.

Target ID - Target Identification is used in conjunction with any mode to identify detected metal objects.

Disc. - Abbreviated term for discrimination. Discrimination allows the detector to selectively reject certain metal objects "junk".

Target - Refers to any object sensed by the detector.

Neutral Response - Indicates no change in threshold tone.

Negative Response - Indicates reduction or loss of tone.

Positive Response - Indicates an increase in tone.


1. Push button - Used for retuning and temporary mode selection.

2. LCD - Liquid crystal display provides target identification and depth. Also displays mode of operation and battery condition.

3. Tuner - Adjusts "Threshold" setting.

4. Mode - Selects primary mode of operation.

5. Target ID - Selects degree of target identification accuracy versus ground mineralization.

6. GND Balance - Adjusts the detector to "balance" out or neutralize ground mineralization.

7. Disc. Adjust - Selects the level of discrimination desired by the operator.

8. Display - Selects display of "A" or "3" battery condition or "operate" mode.

9. Power - Turns the detector on and off

10. Volume - Adjusts loudness of Speaker or Headphone sound.

Charge mode.


Proper tuning and ground balancing is essential in order to achieve optimum performance from your metal detector. "Tuning" means: First, adjust your detector to its "Threshold" and second, adjusting or "balancing" out the ground mineralization at the site to be searched.

Start by setting the "Threshold" as follows: CAUTION: Be sure the loop is at least three feet away from any metal area, and that your batteries are fully charged. Set the controls are shown in figure

Press and hold in the push button on the handle and slowly increase the Tuner clockwise until a barely audible tone is heard. Release the Push Button. The detector is now tuned to it's "Threshold". Passing a coin near the loop will cause an increase in the tone.

Once set, should the threshold change for any reason, other than actually changing the TUNER control, it can be reset by momentarily pressing the push button. Returning to threshold is one function of the push button, the other is mode changing - more on this later.


The objective of "ground balancing " is to adjust the GND Balance control to a point at which the tuning Threshold does not change as the loop is lowered to ground level. Mineralization present in the soil will cause the threshold tone to go up or down until the detector is properly ground balanced.

To ground balance the detector, hold the loop about three feet above the ground. (The detector should be on and adjusted to the tuning "Threshold" as previously instructed). Lower the loop to within one to two inches of the ground. As the loop nears the ground, listen to hear whether the threshold tone increases or decreases in volume.

If the tone decreases, raise the loop back up and increase the GND Balance control (clockwise). If the tone increases, decrease the GND Balance Control (counterclockwise). Press and release the push button to retune after changing the GND Balance control. Lower the loop back to the ground and again listen for a change in tone.

This must be done as many times as necessary until there is no change in the threshold tone with the loop near the ground or in the air.

NOTE: If there is difficulty in making the adjustment, you may be over a hidden metal object. Move to another area and try again.


e GB Disc. Mode is a ground balanced discriminate mode. This mode relies on motion (sweeping the target) in order to function properly.

To use the GB Disc. Mode, start with the instrument tuned and ground balanced as described earlier. Next, set the controls as shown:

Sweep the loop over the search area as shown.

Good objects will respond with a good positive signal tone. Bad objects will cause a negative or broken tone. When the detector responds to a good target, switch the Mode control back to GB for pinpointing. GB can also be selected by pushing in and holding the push button.


Target identification can be used in conjunction with any mode to identify positive target responses.

The Target ID Switch has four (4) positions: Off, Low, Medium, and High. The "Low" position is for use in areas containing very low mineralization. This position requires six or seven sweeps to accurately identify a target.

The "High" position is for use in areas of very heavy mineralization or area where the detector is subject to a lot of interference, such as club treasure hunts. This position may require more sweeps for accuracy.

To use the Target ID, start with the detector properly tuned and ground balanced in the GB mode. Turn the Target ID Switch to the position most suited to the area being searched. In most cases the "Medium" position will work best - use it if you are not sure of the mineralization in the area.

Proceed to search the area. When a target is located simply sweep the loop back and forth over the target six or seven times - stop - and look at the top bar graph of the LCD. The probably target will be indicated on the chart above the last lit segment of the bar graph. The marked off areas of the chart are for general reference - there may be some overlapping of targets into adjacent areas. NOTE: The Target ID Mode is equipped with Target Signal overload alarm. When swinging the loop over a target if the audio tone should momentarily drop in frequency, this is a warning, the circuits have been overloaded by a too strong signal. The Target Identification reading will not be accurate if this happens.

Slow the sweep down or sweep the loop at a higher distance above the target. The overload signal functions only when the Target ID is on.

The Target ID reading on the LCD will remain unchanged until a new target is checked.


The Bottom bar graph of the LCD indicates the depth of a single coin up to six inches deep.

Once a good target has been located, press and release the push button to reset the depth scale. Then place the loop on the ground directly over the target (you will be centered over the target when the bar graph shows the closest distance to the target).

The depth reading works in all modes.

The TR Disc mode can be used on beaches, in houses, or other areas where mineralization is not present. The TR Disc mode will not cancel the effects of mineralized soil

To use the Tr Disc mode set the controls as shown in figure

With the loop in the air, adjust the threshold as described earlier.

Lower the loop to the ground. Press and release the push button to retune. Keep the loop level and at the same light above the ground while searching. Good targets will cause a sharp positive signal while bad targets will cause a negative response.


As mentioned earlier the push button is used to "Retune" by momentarily pressing it. The push button can also be used to change modes.

As an example if the mode switch is set to the GB Mode, pushing in on the push button and holding it in will switch the detector to it's G Sc Mode until the button is released. The LCD will display which mode you are in.

The push button can also be used as an aid in pinpointing. As the loop is moved nearer the target, pressing & releasing the Push button detunes the target signal making it easier to pinpoint. NOTE: When detuning to pinpoint, the depth reading will not be accurate.


COIN HUNTING: Coin hunting, or coinshooting as it is sometimes called, is the use of a metal detector to locate coins and small jewelry wherever people have been and may have lost such items.

The Teknetics 9000 is an excellent coinshooting detector. To coin hunt, adjust the detector for normal outdoor use at the hunt site. Adjust the discrimination control to the trash rejection desired.

CAUTION: High discrimination settings will reject Nickels and Small gold rings and gold coins. However, with the 9000 LCD a very low discrimination setting can be used. When the discriminate audio tone signals a good target, the Target ID can be used to identify the target.

Once it has been determined the target is good, it's depth can be checked.

Carefully remove the target taking care not to damage the object. In lawn areas, caution should be exercised so as to not damage the grass or leave unsightly and dangerous holes.


Old homesteads, ghost towns, and battle fields are some of the areas that may yield interesting and valuable old relics. Since most any item may be of interest, you might want to hunt these areas without using any discrimination or a minimum discrimination setting. In fact for the greatest depth possible, you may want to use the GB Max mode.

To use the GB Max, set the threshold and ground balance as described earlier, except do so with the Mode switch set to GB Max.


The 9000 can be used to locate gold nuggets, silver and copper nuggets, and black sand pockets.

To hunt for nuggets adjust the detector for operation in the GB or GB

Max Mode and search known gold or silver bearing regions. The loop can be submersed underwater for searching shallow streams. The instrument case is not water proof - protect it from water or rain.


Beach combing is a lot like coinshooting except the digging is usually easier. A simple scoop with a screen or holes to allow the sand to escape works quite well.

Wetted beach sand is usually so conductive that maintaining ground balance may be difficult. You may find that it is best to ground balance over dry sand (if mineralization is present) and then switch to GB Disc for searching over wet salt sand.

If the sand is non-mineralized the TR Disc. mode can be used. By adjusting the Disc. Adjust the wet salt sand can actually be "Tuned" out.

Display Reading


The liquid crystal display used in your instrument is rugged and reliable. With proper care, it will give you years of satisfactory service. The chemicals that make this advanced type of display possible require certain practices. To extend the life of the display and to make sure that the display will be ready to operate at a moment's notice, observe the following practices:

1. Protect the display from extended exposure to bright sunlight.

2. Keep the instrument out of high temperature and high humidity environments such as the dashboard of a car on a hot, sunny day.

3. Keep the instrument out of low temperature environments. Operation or storage at temperature below -15? C (5? F) may result in the display being sluggish until the instrument is returned to normal operating temperature.
