ASSEMBLY: Assembly of this unit is easy and requires no special tools. The only assembly required is to attach the search coil and lower stem to the upper stem and control housing.

1. Depress the button on the upper end of the lower stem and slide it Into the upper stem. Push the lower stem up "O that the button snaps Into the third hole from the end of the upper stem.

2. wind the search coil cable around the stem. 3. Install the coil connector into the mating connector on the control housing.


This detector requires two (2) 9-volt ALKALINE transistor-type batteries.

Access to the batteries Is gained by pulling out on the battery doors located on the bottom of the control housing.

The Low Battery Indicator light will come on and stay on whenever the batteries need replacing. It will always "flash" momentarily whenever the Power Switch is turned off. This lets you know it is working properly and batteries are good.

An audible warning (loud tone that can not be tuned out) will also occur when battery life falls below the usable lever. Turn the detector off and Install new batteries.

BATTERY LIFE The use of Alkaline batteries is specified for the detector.

The following tips will help you to get maximum battery life. 1. Use headphones. Using headphones can be very beneficial. Battery life will be greatly extended. Background noise, such as street traffic, is minimized.

Targets are easier to hear.

2. Switch batteries around. Upon Installing a fresh set of 9 volt alkaline batteries keep track of your operating time. After approximately four or five hours use, switch the two batteries around. Audio draws one battery down slightly faster than the other. Thus, switching them around helps insure equal drain.


Remember 95% of all detector malfunctions are either due to faulty batteries or poor connections at the battery clip. Always check your battery condition if you feel your detector Is not working properly. After you have connected and unconnected your batteries several times the prongs on the clip lead may spread apart or the prongs on the battery itself may be spread. Gently squeeze these prongs together with your fingers to insure a good snug fit. Anytime you are going to store your detector make sure you remove the batteries. Storing the batteries in your refrigerator is the best place for them.






This switch is used to turn the detector ON or


It is also used to select search modes.




PINPOINTING AND MODE TOGGLE SWITCH: This is a three (3) position switch with one (1) 'momentary' and two (2) 'lock' positions. The center 'lock' position is the ALL METALS pinpointing mode. From this center position the momentary position can be used for instant retuning or faster detuning of the ALL METALS auto pinpointing mode. The second 'lock' position (away from center) places the detector into Its normal silent search motion mode.


FOR ALL METAL TUNING always push MODE switch to TUNE, then release to center position. FOR DISCRIMINATE place MODE switch in DISC. position.


SENSITIVITY: This control is used to reduce the detector's sensitivity to conditions that may cause the unit to respond in an erratic manner. Broadcasting antennas, power lines and intense mineralization changes can cause the detector to emit false signals. Very large or multiple, closely spaced small trash targets can cause the detector to emit sounds. Generally these signals will sound chopped and will not be repeatable and you will soon learn to recognize them. Turning down the sensitivity control will help reduce the detector's erratic response if the above conditions should ever occur. There will also be some loss of target sensitivity, 90 always set the sensitivity control as high as you can and yet still maintain smooth operation.


DISCRIMINATION AND NOTCH CONTROL. This variable control allows selective response to targets that are in the foil screw cap range. When the MODE switch is set to 'DISC.' the control functions as a standard variable discriminator. As the control Is increased from Its full counterclockwise position, iron, foil, nickels, pull tabs, screw caps, pennies and dimes will be rejected in that order.



Often It is desirable to eliminate some pull tabs without also rejecting nickels, since many types of gold rings are also rejected along with the nickel.

This can be done by setting the POWER switch to 'NOTCH' DISC/NOTCH control now functions as a variable notch


rejection window. The notch can then be adjusted to reject, or 'notch out,' selected types of pull tabs or other trash.




When using the notch feature, most iron and small foil will be automatically rejected by the discrimination circuits. To set the notch, use a pull tab of the type to be rejected. Adjust the NOTCH control to the point (around the area marked PULL TAB on the control) at which the tab is notched out, or rejected. Now check a nickel to be sure it is still accepted. Note that some pull tabs or tab pieces have nearly the same detection properties as nickels and some gold rings. These items can not be separated. In the AUTO NOTCH position most pull tabs, screw caps, iron and light foil will automatically be rejected. Thus, the detector will generally


respond to COINS.


rejected. accepted.


ATI-AUDIO TONE IDENTIFICATION: When operating In the DISC, mode, all detected targets will cause an audio response. Through ATI these targets can be ~laced into three tone categories for identification of the detected item.


NO ~r response




Low Medium High tone tone tone


ALL METAL THRESHOLD When using in the ALL METAL Mode, and after pushing the MODE Switch to TUNE, you should hear a slight Threshold hum from the speaker or headphones. The Threshold level is pre-set for headphone use and might not be loud enough to be heard from the speaker alone by some persons. 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 Mode, you must have a slight Threshold hum at all times.


There Is no Threshold hum In the Disc/Notch Mode and the Ground Control becomes automatic. This is also the "motion" Mode and the detector, (or Target, when practicing) must be kept moving to make a detection.






LOUD Threshold Tone

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



Threshold Tone

With the Ground Balance Control correctly set there will be little or no change in 1118 threshold audio as the loop Is moved up or down near tile ground.

The detector is now ready to operate in the All Metals mode. In this mode any metal(ferrous or nonferrous) will be detected

SALTWATER BALANCE: To balance tile effects of saltwater use the procedures as used for ground balancing difference is that the GNU/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 area try again. 

ID READOUT AND CONTROL The Target ID Readout Control allows you to keep the ZD Readout accurate at all times. For instance, when testing the unit merely adjust the ID Readout Control for the correct reading. 

The Target ID will "lock" onto a target and hold for about 3 seconds. After that, it will momentarily flash the target until a new target Is detected and then It will move to, and "lock" onto, that target. If the ID does not "lock", the Sensitivity control setting should be lowered slightly until a satisfactory ID "lock" is achieved. 

The Depth Indicator will give the approximation, in Inches, for coin-sized objects. Depth Indicator does not "lock" as does the Target ID. 

will peak at the approximate depth and then drop back. ALSO PINPOINTING AS IT PEAKS.

DEPTH INDICATOR: approximate depth

This unique Pinpointing will occur both in the all Metal and Disc/Notch Modes. The Depth Indicator also will react to rejected items while discriminating. You can detect Iron objects at great depths in the Dlsc/Notch Mode by using only the Depth Indicator.

The Target ID will not unlock from the previous Target when a Depth only signal is received. However, there will be no audio sound, so you know you have detected a reject item and not repeated the previous lock on Target.


BLANKER CONTROL: The Pro II Blanker features automatic detection of deep coin targets, while at the same time ignoring all shallow surface targets and trash.


Most experienced Th'ers know that the majority of trash targets they encounter are shallow-generally less than three inches deep. They also know that most older coins, rings and other relies are often deeper than three inches.


Until now, the detector sensitivity could be reduced only to deep targets but not to shallow, often less desirable, targets. This is just the opposite of what most experienced th'ers wanted.


The Blanker variable depth control activates an automatic circuit which reduces, and in most cases completely eliminates~, detection of all shallow targets and trash. Yet, maximum sensitivity and discrimination of the deeper targets is still maintained. 

To use blanking, simple set the variable blanker control to the desired depth and have detector In 'Preset' DISC Mode. When the Blanker Is not in use, the control should be turned all the way left until it "clicks" off.

CAUTION: When using the 3 and 4 Inch blanker settings the SENSITIVITY control must be set at maximum, or as near maximum as conditions permit. If the blanker setting exceeds the sensitivity setting nothing can be detected. 

No blanking will occur while in the All Metal Mode. 


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 are. The Bounty Hunter 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. Use as you would any normal detector-the search signal should peak as the 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. This will prevent loss of detection of some deeper targets, since you are putting more distance between the coil and the target on a careless swing. 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 much like a desired target would sound. 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 the 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. The first 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 mode and check the target response. If the response If 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 19 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.

DETECTION TIPS NOTE: The search coil must be moving to detect a target using the DISC or NOTCH system. However, the detector operates very efficiently, even at very slow speeds.

The DISCRIMINATION MODE is not affected by the ground mineralizatlon, and when used at the beach it will go from wet sand to dry and back without changing tune. The DISCRIMINATION MODE is recommended for areas of heavy surface trash. Any level in this mode will reject small surface area targets such as , 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 get a more reliable reading.

 Accuracy: Although your detector is very accurate on finding coins, 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 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. 

CARE AND SERVICING 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.
