BOUNTY HUNTER 'bud lite' AUTOMATIC VLF Discriminator
Treasure Hunter's Code of Ethics; 1. Respect the rights and property of others. 2. Observe all laws, whether national, state or local. Aid law enforcement of officials whenever possible. 3. Never destroy priceless historical or archeological treasures. 4. Leave the land and vegetation as it was. Fill in all holes. 5. Remove all trash and litter when you leave. 6. All treasure hunters may be judged by the example you set. Always obtain permission before searching on private property. Be extremely careful with your probing, picking up and discarding trash, and ALWAYS COVER YOUR HOLES.
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 so that the button snaps into the third hole from the end of the upper stem. 2. Wind the search coil cable around the stem as shown. 3. Install the coil connector into the mating connector on the control housing.
This is a four position rotary switch which basically turns the detector ON and OFF The OFF position cuts off all power to the detector. The BATT position allows the operator to meter the condition of the unit's bat teries. Following the first 10 minutes of operation the batteries should be checked and replaced if the meter needle does not read within the 'Batteries Good' region. The DISC position of the switch, in conjunction with the Variable DISC./ NOTCH control, functions as a stan dard variable GB Discriminator. The NOTCH position of the switch, in conjunction with the variable DISC./ NOTCH control, functions as a rejection NOTCH.
2. Pinpointing & Mode Toggle: This is a three position toggle switch with two 'lock' positions and one 'momentary' position. The 'center' lock position is the ALL METALS pinpointing mode. In this position target strength is automatically reduced (at a very slow rate) to aid in centering the search coil over the target for accurate pinpointing and recovery.
From the center ALL METALS position the toggle can be pressed into the 'momentary' position and released to quickly retune the ALL METALS if needed.
DISCRIMINATION and NOTCH control: This variable control allows the operator selective response to targets that are in the foil to screw cap range.
When the POWER 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, and 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'. The DISC/NOTCH control now functions as a variable notch rejection window. The notch and 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 con trol) 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.
4. Sensitivity: The primary function of this control is to reduce the detectors sensitivity to those influences that could make the operation more difficult for you. There are some things that can cause the response of the detector to become erratic as you are using it. Normally you will not hear any sound from the detector unless you pass the search coil over a good target. Sometimes a multitude of closely spaced smaller rejected trash targets can cause the detector to emit choppy sputtering sounds. CB radios, broadcasting antennas, intense mineralization changes, and other sources of electrical noise can also cause the detector to emit false signals. The false signals will generally sound 'chopped' and will not be repeatable so you will not have any trouble recognizing them. They can be distracting though, and turning down the sensitivity control will help. This will also cause a small loss of target sensitivity, so always set the sensitivity control as high as you can, while still getting smooth operation.
IN THE FIELD
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 Bounty Hunter does not need to be hurried, so go at a pace that doesn't wear you out.
Sweep in a slightly overlapping pat tern 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 areas with well kept lawns, 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. 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. Another method is to switch to ALL METALS 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 the area 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 some good finds, too.
NOTE: The search coil must be moving to detect a target using the DISC or NOTCH system. However, the detector operates very effectively, even at very slow speeds.
The DISCRIMINATION 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 DISCRIMINATION MODE is recommended for areas of heavy sur face trash. Any level in this mode will reject small surface area targets such as wire, nails, tacks, rivets--that to other detectors may look like coins. Larger junk targets are easily identifiable because of their erratic signal or widespread signal area.
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.
Lets take an example: With the detector set in the DISC MODE and DISCRIMINATION level set to reject Pull Tabs.
With the audio signal produced, at first you may be tempted to pass on and forget it. Don't. A situation like this may be worth an investigation.
1. Switch to the ALL METALS (VLF) MODE for pinpointing
2. Sweep the search coil across the target area in both directions to see if you can isolate the signal into more than one target.
3. 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.
ORIGINAL SWEEP ANGLE
REJECTING THE STEEL BOTTLE CAP
While searching in DISCRIMINATION/NOTCH, an iron bottle cap may 'blip', but can be identified quite easily.
Once a target signal has been received, take notice of its audio strength and your sweep direction. Now sweep over the same target at 90° to the first sweep and compare the strength to the first response. If the signal diminishes at all, you may leave it for a bad target (iron bottle cap). However, if it remains strong, it is a good target. With very little practice, this procedure will become second nature and you will begin to experience the real Joy of using your detector.
Accuracy: Although your detector is very accurate on finding coins it is not perfect and certain items that read 'good' on other detectors will also read 'good' on ours. An example of this would be a pull tab that detects like a large gold ring.
Halo Effect: 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 oxida tion surrounds the coin and not only make the coin appear larger to the detec tor but also makes the coin appear more conductive than normal.
Some nails, nuts and bolts and other iron objects such as old bottle caps ox idize very much and the halo effect around these iron objects make them hard to reject. Try sweeping the loop at 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.
Insensitive detectors are very easy to use. However, you may not find much with them because generally they do not respond to much of anything. By contrast, the Bud lite is a very sensitive deep seeking detector. It will loudly res pond to many weak signals that most detectors will not even sense or at best only whisper on, signals that if missed may mean lost valuable treasures.
This unit can be assembled in either of two configurations or easily converted from one to the other. The electronic control housing can be mounted on the arm rest pole, or can be body mounted.
To body mount:
1. Remove the delta bolts from the bottom of the control housing. Remove the housing from the pole.
CAUTION: DO NOT REINSTALL THE DELTA BOLTS INTO THE HOUSING BOT TOM WHEN USING THE UNIT AS A BODY MOUNT THE CIRCUIT BOARD CAN BE DAMAGED IF THE BOLTS ARE TIGHTENED WITHOUT THE POLE IN PLACE. THEY CAN BE SAFELY INSTALLED ONLY WHEN THE CONTROL HOUSING IS POLE MOUNTED.
2. The control housing is equipped with two holes at the rear of the case which accommodate the spring clips of the shoulder strap.
3. Attach strap to case. Unwrap just enough cable from around the stem to allow good freedom of use.
This detector requires two (2) 9 volt ALKALINE transistor type batteries. (Customer furnished). Such as: Duracell #MN1604 Radio Shack #23-553
Eveready Energizer #522 or any equivalent to these. Access to the batteries is gained by pulling out on the battery doors located on the bottom of the control housing.
The use of Alkaline batteries is specified for the detector. Alkaline batteries can supply the power needed for the many features and powerful performance packed into the sleek lightweight bud case. 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. (3) Make complete use of the batteries. The 'Battery Good' region of the meter is like a fuel gauge--it tells you when the batteries are getting low. However, like the fuel gauge on a car--'Empty' does not always mean you're completely out of fuel. There is usually some reserve. The battery check is like the fuel gauge of the car--there is some reserve. To discover how much reserve your particular unit has simply. run it until it no longer functions, like running the car completely out of fuel, to know how long you can go after the gauge shows empty. (4) Carry a fresh set of batteries. Once you have established where the batteries actually go dead you will know when to install a fresh set. When the battery check shows the batteries are getting low, start carrying a fresh set so you will have them for ready replacement.
To test your batteries, switch power switch to BAT check. The needle must fall within the 'Bat teries Good' on the meter.
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 bat teries. Storing the batteries in your refrigerator is the best place for them.
The following is a picture of all the controls and switches on your unit and a brief statement of their functions.
(1) Power / Disc.
(2) Disc / Notch adjust
(5) Headphone Jack
(4) Pinpointing / Mode /Toggle
1. Power Switch: This switch is used to turn the detector ON or OFF It is also used to check the batteries and select search modes. In the DISC. position the DISCRIMINATION control is activated. The operator can adjust the DISCRIMINATION control to accept or to reject nonferrous targets that fall into the iron to screw cap range. This range includes some larger gold rings and gold coins in addition to zinc pennies and some older pennies. In the NOTCH position most pull tabs can be notched out. Iron, and light foil will automatically be rejected.
2. DISCRIMINATION / NOTCH: Allows variable rejection or notching of nonferrous trash items.
3. Sensitivity: This control is used to reduce the detectors 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 detectors erratic response if the above conditions should ever occur.
4. Pinpointing & 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. This position activates the discrimination / notching circuits.
Your new detector has been designed with simplicity and optimum perfor mance in mind. There are several 'automatic' features that will aid the operator in maintaining top performance from this detector. In fact the most troublesome controls found on standard detectors, the ones that if not proper ly adjusted will result in greatly reduced performance, have been automated on this unit.
1. Place the pinpointing/mode toggle to the 'lock' position that is away from the toggle's center position.
2. Set 'Sensitivity' to it's normal range.
3. Set DISCRIMINATION fully counter clockwise.
4. Turn 'Power' switch to DISC. setting. The unit will now be ON and all controls set for beginning search conditions.
5. Sweep the loop over the search area as shown. Remember: good objects will respond with a GOOD Repeatable POSITIVE signal tone. Bad objects will not respond or will have a broken tone.
6. Refer to 'DETAILED CONTROL FUNCTIONS' for additional operating information.
NOTE: This detector relies on motion to activate the DISC.' mode.
When a target is located generally with a side-to-side sweep, the exact location may be determined by also passing the coil in a forward and back sweep as shown at the right.
By using the AUTO PINPOINTING MODE the detector will automatically reduce target signal strength thereby making it easier to pinpoint the target.
The Bud lite combines efficient electronic pinpointing with a unique 'Quick Check' depth reading circuit. To use simply place the search coil on the ground next to the target, flip the mode toggle to its 'center' setting, and move the coil directly over the target while at the same time noting in which depth block the meter needle peaks. The needle will only 'peak' for a moment as the electronic pinpointing pro cess almost immediately starts detuning the detector for easier pinpointing. With a little practice, you will soon be able to make quick effective depth measurements on coin-sized targets.
However, this also means increased response to trash-induced signals and other sources of interference. At first these responses may seem confusing. One key to handling high sensitivity settings is "signal repeatability." As you sweep the search coil back and forth over the ground, learn to recognize the difference between signals that occur at random and signals that are stable and repeatable. When searching very trashy ground, it is best to scan small areas with slow, short overlapping sweeps. At first, concentrate your efforts only on the well defined, easily repeated, stable signals. As you gain proficiency you will then be able to better evaluate the more questionable signal responses. Some trash items may have the same detection properties as the coins and rings you are searching for. A metal detector looks at the electrical properties of a target, not at its value. Learn to recognize the "good" repeatable target signals from the often chop ped or non-repeatable signals that may occur when sweeping the search coil over very trashy ground. Check suspect targets from different sweep directions to determine the most reliable reading. When in doubt, recover the target and always check for any additional targets.
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 ensure 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 salt water. 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 breakdown.
KEEP IT SAFE . . . Never transport your detector in such a manner that will sub ject 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 the purpose.
COIL. . . The coil is waterproof and may be submerged in either fresh or salt water. Caution should be exercised to prevent water from entering the chassis. After the coil is used in salt water, the coil should be rinsed well with fresh water to prevent corrosion of the metal parts.
EARPHONES. . . The use of earphones will benefit you in two ways. Most ear phones will very effectively block out most of the ambient noise, such as traffic noises and wind noise --- better hear the fainter signals caused by the deeper tones --- will greatly extend the battery life ---
Any good 8 or 16 ohm set with 1/4 inch plug will work.
The following service tips may help if trouble is encountered:
1. The detector will not operate (dead):
a) Check battery condition.
b) Check controls for intermittent operation.
c) Check the loop cable connection to case.
2. Erratic Operation:
a) Check battery condition.
b) Check to see that the loop cable is wrapped snugly around the rod and properly connected.
c) SENS set too high.
3. Constant Oscillating Tone:
a) This effect can be caused by external electrical sources such as: power lines, television sets, CB radios, and/or other nearby detectors.
4. The detector 'drifts' or slowly changes in tone:
a) Sudden temperature changes can cause 'drift' - allow time to stabilize.
b) Component failure can cause rapid steady drift.
5. No sensitivity or poor accuracy:
a) The Disc & Notch modes rely on motion to produce a sufficient signal for activating these circuits.
b) Heavy mineralization can reduce the accuracy of the NOTCH rejection circuits.
c) Check battery condition.
6. Meter needle remains too far down or upscale when unit is turned OFF: This condition may be due to a static charge on the meter face. The charge can be removed by use of a product such as STATIC GUARD and a lint free lens cloth.
7. One or two hour battery life:
a) Use of standard 9 volt general purpose or 9 volt transistor type nickel cadmium batteries may result in very short battery life & diminished performance.
