Teknetics/Bounty Hunter Hi-Tek Basic Operations Manual


Congratulations on your choice of the Hi-Tek Basic Micro-Processor Powered Treasure Finder. It is truly a remarkable instrument and will give you many years of fine service.

The Hi-Tek Basic is easy to understand and operate, yet delivers top performance and power.

We have eliminated the typical "Menu" system that makes a computer detector difficult to understand and operate. Instead, we have developed a more advanced "Latch" system that does not require a menu to select and display the various features.

The unique LCD Target Readout System will display all functions simultaneously. Target ID, Depth Indicator and Pin Point Bullseye all respond together, with each detection. No flipping switches back and forth to get the total picture. With the Hi-Tek Basic, the information you want and need comes up quickly and completely every time.

The Hi-Tek Basic has two MODES of operation:


The mode selection switch is conveniently located on the handle.

In the Motion-DISC Mode, the Touch Pad can be used to quickly select any combination of targets for Accept or Reject. Trash can be rejected with no loss of sensitivity.

The No Motion ALL METAL THRESHOLD Mode is used to achieve deep penetration of all targets in highly mineralized soil. Target Reject is not used in the ALL METAL THRESHOLD Mode.

The Hi-Tek Basic features Target Identification, Depth Reading and Pinpointing in either Mode.



This detector requires four 9-volt ALKALINE batteries. The batteries are accessed by pulling out on the battery doors located on the bottom of the control housing.

The Battery Strength Indicator is displayed constantly while unit is on. An audible warning (loud tone that can not be tuned out) will also occur when battery life falls below the usable level. Turn the detector off and install new batteries whenever this occurs.

BATTERY LIFE can be greatly extended by using headphones, which consume less power. Switch the batteries from side to side after four or five hours of use to insure equal drain.


Assembly of this unit is easy and requires no special tools. All you have to do is attach the search coil and lower stem to the upper stem and control housing. Then wind the search coil cable from the control housing around the stem to take up the slack.


POWER SWITCH/VOLUME: This switch is used to turn the detector ON or OFF and set the VOLUME level.

SENSITIVITY: This control is used to reduce sensitivity whenever conditions that may cause chatter are present. Always set the Sensitivity Control as high as you can while still maintaining smooth operation.

MODE TOGGLE SWITCH: This is a three position switch with one center and two side positions. The center position is the ALL METALS THRESHOLD Mode. The TUNE position is momentary and used for instant retuning of the ALL METALS THRESHOLD mode. The DISC position (away from center) places the detector into the silent "Motion" Mode.


The Target ID Readout control allows you to keep the ID Readout accurate at all times. For instance, when testing the unit, if a nickel reads as a pull tab, or vice-versa, merely adjust the ID Readout Control for the correct reading.


DISCRIMINATE: Place MODE Switch in DISC position. The TOUCHPAD can now be used to select any combination of targets for Accept or Reject. TUNING and GROUND BALANCE are now automatic and "Motion" is required. The searchcoil (or target, when practicing) must now be kept moving to make a detection. Objects held still under the searchcoil will be tuned out.


1. Push ALL METAL pad to detect all metals.

2. Push PRESET I to reject iron, foil and pull tabs.

3. Push PRESET II to reject iron, foil, pull tabs, screwcaps and zinc pennies.

4. Touch TARGET SELECT pad and targets appear one at a time on the LCD Display for you to accept or reject. Program your own combination of 11 targets

When using TARGET SELECT, you can stop at any point and lock in on what you have by pushing the ALL METAL pad. For example, if you only want to reject TAB, you start by pushing the TARGET SELECT pad. The Target Arrow will come up blinking under IRON. Push the ACCEPT pad and the Arrow will move to foil, and so on. When the Arrow comes up under TAB, you push REJECT. An R, for reject, will appear under TAB and the Arrow will move to GOLD. Since you don't want anymore Rejects, merely push the ALL METAL pad and all other targets are automatically accepted and the unit is ready for detection.

To remove the previous TARGET SELECT selection and make a new one, just push the TARGET SELECT pad again. From any other setting, you can go directly to ALL METAL or a PRESET Mode at any time . When first turning the unit on and placing in the DISC Mode, it will automatically go to ALL METAL until another Mode is selected. Push the pads firmly to assure good contact.



· The Digital Readout gives targets a numerical value. It is accurate enough to tell the difference between clad and silver coins. Silver coins will have a higher number than the same coin in clad.

· The ID Arrow locks on when targets are detected.

· R indicates Reject selections.

· Depth locks on for coin-sized objects.

· Battery Indicator lets you know the actual condition of your batteries at all times.

· Pinpoint Indicator comes on full when you are over the target.

· "TARGET" stays on when using any Target Mode.

(graphic goes here illustrating readout correlations of silver, clad, etc.)


The most accurate Target ID will occur from four to eight inches deep. On targets reading less than four inches, raise the searchcoil a few inches and sweep the target again, for a more accurate ID. On deeper targets, over eight inches, be aware that the ID might not be accurate. It is a good idea to always dig a deep, repeatable, target.


The Depth Indicator will give the approximate depth, in inches, for coin-sized objects.

Bullseye Pinpointing will occur both in the ALL METAL THRESHOLD and DISC Modes. The Bullseye will also respond when Reject targets are passed over. This will give you an indication of the amount of trash you are encountering.


When operating in the DISC MODE, detected targets will have three distinct tone categories for helpful identification of the detected item.

For ALL METAL THRESHOLD TUNING always push MODE switch to TUNE, then return to center position. Set GROUND BALANCE as described in GROUND BALANCE section. When using in the ALL METAL THRESHOLD Mode, and after pushing the MODE Switch to TUNE and returning it to center, you should hear a slight Threshold hum from the speaker or headphones. The Threshold hum is easily adjustable by moving the Ground Balance control slightly, one way or the other. The movement required is slight and will not affect the Ground setting. This should be done while setting the Ground Control for proper Ground balancing, as a slight threshold hum is necessary to determine if you are losing or gaining signal from ground conditions. By the same token, if you are getting too loud of a Threshold hum, either through the speaker or headphones, it can be reduced with a slight movement of the Ground Control.

For Maximum Sensitivity in the ALL METAL THRESHOLD Mode, you must have a slight Threshold hum at all times.

There is no Threshold hum in the DISC Mode, and the Ground Control becomes automatic.


To adjust the Ground Control, hold the unit with the searchloop at least three feet above the ground. Then adjust the Ground Control knob to the new position, and before lowering the searchloop to the ground, push the toggle switch to TUNE and then release back to ALL METAL. Now lower the searchloop to about one foot above the ground. The Threshold should be steady as described above. If necessary, adjust the Ground Control knob very slightly at this time to get a moderate threshold hum. Now drop the searchloop to within 1/2 inch of the ground. If the Ground Control setting is correct, the threshold tone should not change significantly. If it does change, either gaining or losing tone, repeat the above until the correct setting is found.

As you move about, while searching, the Threshold tone may vary up and down slightly due to soil changes. This usually does not affect the sensitivity of the unit and should not require further adjustment. If the Threshold tone does change a significant amount, readjustment might be necessary. Before adjusting the Ground Control knob, try raising the searchloop one foot from the ground and pushing the tune switch again and then lowering the searchloop back to the ground. Sometimes the change in Threshold Tone is due to reasons other than ground conditions and can be easily corrected in this manner. If not, then repeat the full procedure.



If the Ground Balance Control is not correctly set, moving the loop up and down will cause a significant change in the threshold audio.


With the Ground Balance Control correctly set, there will be little or no change in the threshold audio as the loop is moved up or down near the ground.

The detector is now ready to operate in the ALL METAL THRESHOLD MODE.

In this MODE any metal (ferrous or nonferrous) will be detected.

Saltwater Balance: to balance the effects of saltwater use the same general procedures as used for ground balancing. The difference is that the GND/Salt control will balance salt around the counterclockwise area of its range, near the word 'Salt'.

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


The detector should be held in a position that is comfortable for you. Sweep the detector from side to side in about a three foot arc. The unit does not need to be hurried, so go at a pace that doesn't wear you out. Sweep in a slightly overlapping pattern as shown. The search signal will peak as a target center is passed. Try to keep the search coil parallel to the ground at all times and avoid lifting the coil off the ground at the end of each swing. Since you are putting more distance between the coil and the target on a careless swing, this will prevent loss of detection of some deeper targets. In flat areas, sweep the coil as close to the ground as possible without touching. Hitting the ground or rocks may cause a false signal similar to the sound of a desired target. Sweeping the coil too high above the ground results in a loss of depth.

When operating the detector, some false signals may occur at the end of your swing. At this point, where the coil reverses direction, the detector is most susceptible to trash-induced noise. There are ways to tell whether these noises are deep good signals or trash. One way is by repeatability. Trash-induced signals will not be repeatable as you swing the coil over the suspected target several times, while a good target response will be repeatable. You may also want to use the Blanker to ignore the surface targets.

Another method is to switch to ALL METALS THRESHOLD Mode and check the target response. If the response is weak, it may well be a deep good target, but if it is very strong, it is probably trash.

If the trash in an area is so heavy that you are getting a lot of choppy sounding false signals, you can get better results by slowing down your sweep speed and using shorter sweeps. It is also helpful to hunt areas twice, the second time at right angles to the first time. This will allow detection of some targets that were hidden by trash the first time due to the sweep direction.

If there is any doubt whether a target is good or not, DIG IT.

If you don't dig any junk at all, you are surely passing up good finds too.


NOTE - The search coil must be moving to detect a target using the DISC system. However, the detector operates very efficiently, even when swung at very slow speeds.

The DISC Mode is not affected by the ground mineralization, and when used at the beach, it will go from wet sand to dry and back without changing tune. The DISC Mode is recommended for areas of heavy surface trash. This Mode can reject small surface area targets such as wire, nails, tacks and rivets that to other detectors may look like coins. Larger junk targets are easily identifiable because of their erratic signal or widespread signal areas.

Often you will receive a signal from a target that is difficult to read to really determine what it is. What may seem to be a bad target because of the signal pattern, may be a combination of targets.

If you do determine that there is more than one target present, try sweeping the coil over it at a more favorable angle in the DISCRIMINATION or NOTCH MODE to receive an improved reliable reading.

Accuracy: Although your detector is very accurate on finding coins and other valuable metals, it is not perfect.

An example of this would be a pull tab that detects like a large gold ring.

Halo Effects: Gold and silver coins don't oxidize much so they have very little halo effect. However, nickels and pennies do oxidize quite a bit and this oxidization surrounds the coin and not only makes the coin appear more conductive, it also makes the coin appear larger than normal.

Some nails, nuts and bolts and other iron objects (such as old bottle caps) oxidize very much and the halo effect around these iron objects makes them hard to reject. Try sweeping the loop different directions over the target. A good target will have a fairly stable reading; whereas, a bad target will usually not.

Freshly buried coins may not respond exactly the same as coins buried for a long time.

Waterproof: the searchcoil on your Hi-Tek is waterproof, and may be submerged up to the instrument cabinet for searching stream edges, etc.


PROPER CARE FOR YOUR DETECTOR... Metal detectors are sensitive electronic instruments. Although it does not have to be babied, reasonable care must be taken to help insure a long trouble-free life for your detector.

KEEP IT CLEAN... Take a few minutes after each use to remove dirt and dust. Wipe the housing and wash the coil--especially if it has been dipped in saltwater. A plastic bag over the control box at the beach will help protect the unit from sand and prevent corrosion due to salt air.

KEEP IT COOL... Never store your detector in an extremely hot environment, such as an automobile trunk in the summer, for extended periods of time. The prolonged heat will not only shorten battery life considerably but can cause electronic components to break down.

KEEP IT SAFE... Never transport your detector in such a manner that will subject it to extreme vibration or shock. The unit may be cushioned by wrapping it in a blanket or by putting it in a carrying bag or case designed for that purpose.

COIL... The coil is waterproof and may be submerged in either fresh or saltwater. Caution should be exercised to prevent water from entering the chassis. After the coil is used in saltwater, the coil should be rinsed with fresh water to prevent corrosion of the metal parts.
