TEKNETICS 7700 OPERATING INSTRUCTIONS

Teknetics Inc., "dedicated to quality and performance"

FOREWORD

Teknetics is a corporation formed by individuals who are dedicated to the premise that the pro ducts they manufacture should have lasting quality, the latest in design technology and the maximum range of features that can be obtained for your money.

With these goals in mind, from its first inception, your detector was designed by an engineering group which has many years invested in the field of detectors, having already designed the major innovations in use by other manufacturers.

By carefully reading the instructions in this manual, you will obtain all of the advantages designed into your instrument, but the best performance can only be achieved by practice until you are proficient enough to be able to identify even the slightest variation in target response.

GOOD HUNTING!

IMPORTANT

Protect your investment - Record the serial number (located inside the "A" Battery compartment) of the unit and the purchase date in the space below. Always reference this information in any correspondence.

Model No. Serial No. Purchase Date

Please retain your shipping carton. In the event your detector should ever require repair this package will afford the best possible protection for shipping. (Also good for storage of detector).

W A R N I N G

This TEKNETICS instrument is sealed at the factory to protect your warranty rights. Any evidence of tampering with the seals will automatically void any warranty rights you may have. Return the instrument to the factory or your nearest authorized service station.

ASSEMBLY

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

Assemble 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.

The 7700 requires fourteen (14) 1 volt "M " penlight batteries. Batteries are available from most local dealers.

To install the batteries - remove the compartment doors on the bottom of the case. Install the cells according to the legend for + and -.

A fresh set of batteries will give 7 to 10 hours of continuous use. Battery life can be prolonged with intermittent use and by use of headphones equipped with volume controls.

Note: This detector is not equipped with battery check, therefore, you should keep track of total operating time per set of batteries.

Caution: Never attempt to recharge standard M or Alkaline batteries.

Your new Teknetics detector can be equipped with re chargeable Nickel Cadmium batteries which vill save many hundreds of dollars in battery purchases as they may be re charged as many as a thousand times or more.

The optional rechargeable NiCad kit (retail price $39.95) is available through your local Teknetics dealer.

Caution:

The Nickel Cadmium batteries will require charging for a period of 14 to 15 hours to bring them to full capacity, as they are shipped only partially charged. Once installed - It is not necessary to remove the batteries to recharge them, Simply plug the charger into the charger socket on rear of detector and connect to an electrical outlet. Once charged, a minimum of seven hours continuous use can be expected per charge.

Nickel Cadmium batteries can develop a memory pattern limiting their available capacity. It 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 on the 7700. 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 that 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 or three months at a time.

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.

OPERATION

Your new 7700 has been designed with simplicity and optimum performance in mind.

To operate:

(1) Flip the toggle switch (Handle) to the right.

(2) Turn the "Power" switch fully clockwise to "On".

(3) Sweep the loop over the search area as shown. All metal objects, except iron, will respond with various positive signal tones.* Iron objects will cause a negative (quiet) or broken tone.

NOTE:

This detector relies on motion to activate the GB Disc. mode

SWEEPING LOOP OVER TARGET

(4) To pinpoint a good object -flip the toggle switch to the left. slowly "X" the target.

Note: The 7700 uses A.T.I. (Audio Target Identification) as an aid in determining "Good" Targets from "Bad" targets. Nonferrous metal objects will cause the 7700 to respond with a certain audio pitch (frequency) that will almost always be the same for a particular target. For example, foil causes a positive audio response of about 350 Hz and a Dollar is about 1,100 Hz.

TIPS FOR OPERATION

This detector relies on motion to activate the GB Disc. mode circuitry.

SWEEPING LOOP OVER TARGET

POSITIVE RESPONSE

HOLDING LOOP Motionless

NO RESPONSE

2. Interpreting different types of responses: With A.T.I. you can tell many things about a target just by the sound response of the detector. As an example, using the detector in the GB Dix. mode you can expect the following results.

3. Sometimes targets close together will cause a confusing signal - Try sweeping from different angles to help isolate Targets.

Toggle switch Mode change with electronic pinpointing:

The 7700 is equipped with electronic pinpointing, simply Flip the toggle switch to the left and very slowly "x" the target as shown:

The detector will automatically reduce target signal strength thereby making it easier to pinpoint the target.

Your TTO can tell you many things about a particular target that can be helpful in determining whether or not to dig. Make use of all the information available as an example:

The sound response can tell a lot - a coin usually gives a good solid sound regardless of sweep direction. when checking a target, listen to the "Size" of the sound in the GB Pinpointing mode - a large target produces sound over a greater area than does a single co in .

Hot Rocks: On all motion type detectors, you will find some targets that read "good" in the "motion discrimination" mode but when you switch to the "All Metal" mode to pinpoint, you find that the target had "nulled out" or caused the All Metal Mode to "go quiet" when directly over this target. This is because you have located what people call "Hot Rocks". The hot rocks are objects that are less conductive than the ground you are hunting.

Respect the rights and property of others. Check local laws and ask permission to hunt. Always fill all holes and avoid damage to lawns .

FIELD APPLICATIONS

COIN HUNTlNG

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.

In lawn areas, caution should be exercised so as to not damage the grass or leave unsightly and dangerous holes

RELIC HUNTING

Old homesteads, ghost towns and battle fields are some of the areas that may yield interesting and valuable old relics

BEACH COMBING

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

GLOSSARY OF TERMS

1. Threshold Tone - Barely audible tone set by the factory to achieve the best sensitivity to a metal object.

2. Neutral Response - Indicates no change in threshold tone.

3. Negative Response - Indicates loss of tone.

4. Positive Response - Indicates an increase in tone.

5. G.B./A.T.I. - Abbreviated term for Ground Balanced audio Target ID. This mode allows both ground neutralization and Target Identification.

(Requires Motion Over Target)

6. Target - Refers to any object sensed by the detector.

7. Mineralization - Refers to soils containing ferric oxides or magnetic particles.

8. Halo Effect - Certain metals, when buried for long periods, oxidize and leech into the surrounding soil. This results in a "metallic Halo" around the buried object.

9. A.T.I. - Abbreviated term for Audio Target Identification. A certain audio pitch identifies the type of metal object located.
