This model could be termed a modern remake of the old VLF/TR detector. It looks eerily similar to Bounty Hunter's current "VLF" model. I'd give this unit a close lookover and would probably grab it if I saw it at a yard sale, just on the off-chance that it's functionally related to one of the older venerable BH "Big Bud" models. My "equivalents" list says it might be derived from the Tracker III. It's all descended from the same heritage in any event.
Here's the newer version manual in pdf format

Treasure Hunter's Code Of Ethics
All treasure hunters might be judged by the example you set, Here are a
few basic rules you should follow while using your detector.
Always get permission before searching any site.
Respect the rights and property of others.
Observe all national, state, and local laws while treasure hunting.
Never destroy historical or archaeological treasures. If you are not
sure about an object you have found, contact a museum or historical
society in your area.
Leave the land and vegetation as it was. Fill in any holes you dig.
Use your detector only in safe areas
Dispose of any junk you find, only in approved areas. Do not leave it
for the next treasure hunter to find.
To enjoy your Metal Detector for many years, follow these suggestions.
Keep the metal detector dry; if it gets wet, wipe it dry immediately.
Use and store the metal detector only in normal temperature
Handle the metal detector carefully; do not drop it.
Keep the metal detector away from dust and dirt.
Wipe the Metal Detector with a damp cloth occasionally to keep it
Modifying or tampering with the metal detector's internal components can
cause a malfunction and might invalidate its warranty. If your Metal
Detector is not performing as it should, take it to your local RadioShack
store for assistance.
The search coil supplied with the detector is waterproof and can be
submerged in either fresh or salt water. However, do not let water enter
the detector's control housing. After using the search coil in salt water,
rinse it with fresh water to prevent corrosion of the metal parts.
A Quick Look at Your Metal Detector's operating controls.
MODE - lets you select from OFF, VLF, TR1, TR2. (See
"Turning On the Detector" below.
GROUND - Compensates for false signals from mineralized soil.
(See "Adjusting Ground" below.)
VOLUME - lets you adjust the volume of alert tones.
DISCRIMINATION - lets you adjust the metal detector's ability to
distinguish between different types of metal. (See
"Adjusting Discrimination" below.)
Analog Meter - Shows strength of signals being received by the metal
LOW BATT indicator - lights when the battery is getting low and needs
Sensitivity - lets you adjust the detection depth. (See "Adjusting
TUNING - Adjusts the balance between the receiver and
transmitter. (See "Tuning the Detector" below.)
Your RadioShack Metal Detector distinguishes between ferrous and non
ferrous metals. Ferrous metals contain iron, while non-ferrous metals
such as gold, silver, copper, platinum, aluminum, lead, and zinc do not.
When the detector senses a metallic object, the meter reading changes and
the detector sounds one of three tones. The tone depends on what metal is
detected. The higher the tone's pitch, the stronger the detection.
Preparing The Detector
Turning On the Detector
Hold the detector in a comfortable position, then rotate MODE to the
VLF (Very Low Frequency) - to adjust TUNE and GROUND. (See "Adjusting
Ground" and "Tuning the Detector" below.)
TR1 (Transmit 1) - to detect extreme differences in metals, such
as iron and gold. The difference between iron
and gold shows on the meter (iron in the
ferrous section, gold in the non-ferrous
TR2 (Transmit 2) - to detect finer distinctions between metals,
such as aluminum and gold (see "Adjusting
Tuning the Detector
Tune fine-tunes the balance between the detector's receiver and
transmitter circuitry to provide consistent pointer and tone indications.
Follow these steps to set TUNE.
1. Rotate VOLUME to the 10 o'clock position.
2. Set MODE to VLF.
3. Set GROUND, DISCRIMINATION, and SENSITIVITY to mid-range.
4. Hold the search coil at least 1 foot away from the ground and any
metal object, hold down the red button on the handle and slowly rotate
TUNE until the analog meter pointer resets at or near 0.
As you search, you can fine-tune the detector using the other controls
(see "Fine-Tuning the Detector" below).
Note: Press the red button on the handle at any time during operation to
automatically return the pointer to the center of the analog meter.
Testing And Using The Detector
To learn how the detector reacts to different metals, you should test it
before you use it the first time. You can test the detector indoors or
1. Remove any watches, rings, or other metal jewelry you are wearing,
then place the detector on a wooden or plastic table.
2. Adjust the search coil's angle so the flat part faces the ceiling.
Note: Never test the detector on a floor inside a building. Most
buildings have metal of some kind in the floor, which might
interfere with the objects you are testing or mask the signal
3. Set MODE to TR1.
4. Move a sample of the material you want the detector to find (such as a
gold ring or a coin) about 2 inches above the search coil.
Notes: The search coil will not detect without motion. You must move the
object since you are not sweeping with the detector at this time.
If you are using a coin, the detector detects it more easily if you
hold it so a flat side (not the edge) is parallel with the flat
side of the search coil.
If the detector detects the material, the pointer moves to FERROUS or NON
FERROUS while the detector determines the type of metal it is detecting.
If it detects non-ferrous metal, it also sounds a tone.
If the detector does not detect the material, check the LOW BATT indicator
and verify that the search coil is properly connected. Also you might need
to fine-tune the detector. See "Fine-Tuning the Detector" below.
Outdoor Testing and Use
1. Find an area on the ground outside where there is no metal.
2. Place a sample of material you want the detector to find (such as a
gold ring or a coin) on the ground. (If you are using valuable metal
such as gold to test the detector, mark the area where you place the
item, to help you find it later. Do not place it in tall grass or
3. Set MODE to TR1.
4. While holding the search coil level about 1-2 inches above the ground,
slowly move the search coil over the area where you placed the sample,
sweeping the search coil in a side-to side motion.
Search Coil Sweeping Hints:
Never sweep the search coil as if it were a pendulum. Raising the search
coil while sweeping or at the end of a sweep causes false readings.
Sweep slowly; hurrying makes you miss targets.
If the detector detects the item, it sounds a tone and the pointer moves
to the type of metal it found. When you detect metal, switch MODE TR1 to
TR2 to determine the quality of the metal.
If the detector does not detect the material, make sure you are moving the
search coil correctly.
Notes: The detector responds with a strong signal when it detects most
valuable metal objects. If a signal does not repeat after you
sweep the search coil over the target a few times, the target is
probably junk metal.
False signals can be caused by areas containing large amounts of
trash, electrical interference, or large irregular pieces of junk
metal. False signals are usually broken or non-repeatable.
5. Try finding other metal in the area. When you find a metal item, wait
a few seconds after the tone stops before continuing to allow the
detector time to reset (or, press the red button on the handle to
return the pointer to the center of the analog meter).
Fine-Tuning The Detector
After you become familiar with how your detector works, you can fine-tune
it to make it less sensitive to interference and more selective in what it
To adjust the search coil's ability to detect objects at different depths
in the soil, rotate Sensitivity between MIN and MAX. For maximum detection
depth, leave SENSITIVITY set as high as possible. If the detector makes a
"chattering" noise, decrease SENSITIVITY until the chatter stops.
Setting GROUND takes a little time but is critical for accurate operation.
GROUND tunes out false signals from mineralized soil. Follow these steps
to set GROUND.
1. Set MODE to VLF and lower the search coil to 1/2 to 2 inches above the
2. If the pointer swings to the right (Non-ferrous), turn GROUND to
NORMAL. If the pointer swings to left (Ferrous), turn GROUND to
3. Raise the search coil about 1 foot from the ground and press the red
button on the handle. The pointer returns to the center.
4. Repeat Steps 1-3 until the pointer stays close to the center each time
you lower the search coil to the ground.
After you set GROUND, the detector is set for the soil type at that
particular site. Do not reset it until you use the detector at a different
Discrimination is the detector's ability to differentiate between types of
metal. The detector's DISCRIMINATION setting determines whether the
detector will distinguish between different types of ferrous and non
If MODE is set to TR2, start with DISCRIMINATION set to mid-range. While
you use the detector, adjust DISCRIMINATION to the best position. As you
set DISCRIMINATION higher, the detector becomes more sensitive to the
differences between large aluminum and gold pieces, for example, but some
small valuable pieces such as coins and small rings, might be overlooked.
As you set DISCRIMINATION to higher levels, the detector first does not
detect small places of silver paper, then thick foil, and finally metal
objects like pull tabs from aluminum cans.
Note: Each time you use the detector in a different area you must readjust
DISCRIMINATION. Each search location presents new challenges.
Because your detector is extremely sensitive, trash-induced signals and
other sources of interference might cause signals that seem confusing.
The key to handling these types of signals is to dig for only those
targets that emit a strong, repeatable signal. 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
To reduce false signals when searching areas containing large amounts of
trash, scan only a small area at a time using slow, short overlapping
No detector is 100 percent accurate. Various conditions influence metal
detection. The detector's reaction depends on a number of factors:
The angle at which the object rests in the ground.
The depth of the object.
The amount of iron in the object.
The size of the object.
Pinpointing A Target
Accurately pinpointing a target makes digging it up easier. This takes
practice, and we suggest you practice finding and digging up small metal
objects on your own property before you search other locations.
Sometimes, targets are difficult to accurately locate due to the sweep
direction. Try changing your sweep direction to pinpoint a target.
1. When the detector locates a buried target, continue sweeping the
search coil over the target, in a narrowing side-to-side motion.
2. Make a visual note of the exact spot on the ground where the detector
3. Stop the search coil directly over this spot on the ground. Then move
the search coil straight away from you and straight back toward you a
couple of times.
4. Make a visual note of the exact spot on the ground where the detector
5. Repeat Steps 1-3 at a right angle to the original search line, making
an "X" pattern. The target will be directly below the "X" at the point
of the loudest response.
Notes: If trash in an area is so heavy and you get false signals, slow
your sweep speed and use shorter sweeps.
Recently buried coins might not respond the same as coins buried
for a long period of time because of oxidation.
Some nails, nuts, bolts, and other iron objects (such as old bottle
caps) oxidize and create a "halo" effect. A halo effect is caused
by a mixture of natural elements in the ground and the oxidation
created by different metals. Because of the metal mixtures, target
signals might not be in a "fixed" position. This effect makes these
objects very hard to detect accurately. (See "Fine-Tuning the
Assembling The Detector
Assembling your detector is easy and requires no special tools. Just
follow these steps.
1. Turn the stem's lock nut clockwise until it loosens.
2. Lengthen or shorten the stem so when you stand upright with the
detector in your hand, the search coil is level with and about 1/2 to
2 inches above the ground with your arm relaxed at your side.
3. Turn the stem's lock nut counterclockwise to lock it in place.
4. Unscrew the knobs on the search coil and remove the knobs and
connector. Insert the stem and align the holes on the search coil
bracket and the stem. Push the connector through the holes, then
replace and tighten the knobs.
5. Wind the search coil cable around the stem. Leave enough slack in the
cable to let you adjust the search coil when you are hunting on uneven
6. Insert the search coil's plug into the search coil jack on the
detector's control housing so the pins on the plug are aligned with
the holes in the jack.
CAUTIONS: The search coil's plug fits into the connector only one way. Do
not force the plug or you could damage it.
To disconnect the search coil's cable from the detector, grasp
the plug and pull it out of the connector. Never pull on the
7. Loosen the knob at the search coil's end, then adjust the search coil
to the desired angle. (The search coil should be parallel with the
ground.) Tighten the knob just enough to keep the search coil from
rotating or wobbling.
CAUTION: Do not over-tighten the search coil or use tools such as
pliers to tighten it.
8. Loosen the knob at the base of the handle, insert the arm support, and
tighten the knob.
Your detector requires two 9V alkaline batteries (not supplied) for power.
For the best performance and longest life we recommend RadioShack alkaline
CAUTIONS: Use only fresh batteries of the required size and recommended
Do not mix old and new batteries, different types of batteries
(standard, alkaline, or rechargeable) or rechargeable batteries
of different capacities.
1. If the detector is on, turn MODE to OFF.
Note: When you turn the mode switch to OFF, the LOW BATT indicator
2. Press the right battery compartment cover's tab and slide the cover
off in the direction of the arrow.
3. Place a 9-volt battery into the battery compartment on top of the
ribbon, matching the polarity symbols (+ and -) marked inside.
4. Replace the right battery compartment cover.
5. Press the left battery compartment cover's tab and slide the cover off
in the direction of the arrow.
6. Place a 9-volt battery into the battery compartment on top of the
ribbon, matching the polarity symbols (+ and -) marked inside.
7. Replace the left battery compartment cover.
WARNING: Dispose of old batteries promptly and properly. Do not burn or
CAUTION: If you do not plan to use the detector for a week or more, remove
the batteries. Batteries can leak chemicals that can destroy
Notes: For better life, exchange the two batteries periodically.
You can extend battery life by using headphones, which require less
power than the built-in speaker. See "Using Headphones," below.
If the LOW BATT indicator lights during normal use or the detector does
not function properly, replace the batteries. If it still does not
function properly, you might need to reset the detector.
You can connect a pair of stereo headphones (not supplied) to the detector
so you can listen to it privately. Using headphones also saves battery
power and makes it easier to identify subtle changes in the sounds you
hear, for better detection results. Your local RadioShack store has a wide
selection of headphones.
To connect headphones to the detector, insert the headphones' 1/8-inch
plug into the PHONE jack on the side of the control housing.
The detector's internal speaker disconnects when you connect headphones.
To protect your hearing, follow these guidelines when you use headphones.
Set the volume to the lowest setting before you begin listening. After
you begin listening, adjust the volume to a comfortable level.
Do not listen at extremely high volume levels. Extended high-volume
listening can lead to permanent hearing loss.
Once you set the volume, do not increase it. Over time, your ears adapt
to the volume level so a volume level that does not cause discomfort
might still damage your hearing.
Do not wear headphones while operating a motor vehicle or riding a bicycle
This can create a traffic hazard and could be illegal in some areas.
Even though some headphones let you hear some outside sounds when
listening at normal volume levels, they still can present a traffic

see if you can eliminate the problem. If you can't, take the detector to
your local RadioShack store for assistance.
