Digger Metal Detector

I received a Radio Shack Metal Detector without an instruction book. On the control box is number 63-3006. It has four knobs on the control box titled Mode, Ground, Discriminator and Sensitivity. Also a knob for tone and a red light for Ferrous and green light for Non-ferrous. On the handle is a red button and it has around the button Push Auto Tune. Is this an old model and is there anything like it on the market today? And where would I find an Owener’s Manuel?

How to Identify and Resolve Common Issues ?

Radio reflectometry is the measurement of radiofre- quency electromagnetic (RFEM) waves reflected by an object. It is widely known that metal objects such as airplanes reflect radio waves that can be detected by radar receivers.
Metal detectors create a magnetic field by using a brief pulse of electrical current. The magnetic field will be reflected back to the machine if there are any metal objects present, such as a watch or a belt buckle. The return signal is detected by the machine and a beeping noise is produced to alert the TSA agent.
Metal detectors use electromagnetic fields to passively or actively detect the presence of metallic objects. Passive detection measures the changes in the Earth`s magnetic field caused by an object.
The detector consists of a special center-tapped transformer feeding two diodes in a full wave DC rectifier circuit. When the input transformer is tuned to the signal frequency, the output of the discriminator is zero. When there is no deviation of the carrier, both halves of the center tapped transformer are balanced.
An RF detector monitors or samples the output of an RF circuit and develops a dc output voltage pro- portional to the power at that point. What do you do with an RF detector? RF detectors are used primarily to measure and control RF power in wireless systems.
Radar works by sending out radio waves, a type of electromagnetic wave, in pulses through a radio transmitter. The waves are reflected off of objects in their path back toward a receiver that can detect those reflections.
A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies.
The system works by detecting the movement of metal (ferrous) objects that move between the two sensors.
Airport scanners can see detailed images of your luggage contents such as metallic and non metallic objects, but also organic materials.
A considerable amount of iron can make a metal detector overload. Electrically conductive minerals, soil minerals, and iron underground pipes can also interfere with a metal detectors` signal.
Metals That Can`t Be Detected

Stainless steel has low magnetic permeability, which means it does not produce a signal strong enough to be detected. Other items that metal detectors won`t be able to locate include: Gemstones. Paper.

Most metal detectors can detect coins at an average maximum depth of 10 to 16 inches. Metal detectors transmit radio frequency signals from the search coil to locate the targets from the ground`s surface to a depth of over 20 feet for large deep treasures.
A radio frequency (RF) detector is a device used to detect the presence of RF waves either in a wireless or wired (on RF Cable) physical transmission medium. They are also known as RF power detectors or RF responding detectors and are available as devices or modules.
How Does the Cell Phone Detector Work? The Cell Phone Detectors come with bugs which are meant to detect RF transmission signal. The moment this bug detects the RF transmission signal from an activated cell phone, the LED light started blinking, and it starts making a beep alarm.
But radio waves don`t carry information all by themselves. They need to be altered, or modulated. A signal–a transverse sound wave–overlays the carrier wave, forcing it to change. There are two ways radio stations modulate their carrier waves: amplitude modulation, or AM, and frequency modulation, FM.
The RF Bug Detector is a perfect device for detecting audio bugs. It has a wide detecting frequency range (from 10 MHz to 6.0 GHz).
Inductive proximity sensors can only detect metal targets. They do not detect non-metal targets such as plastic, wood, paper, and ceramic. Unlike photoelectric sensors, this allows a inductive proximity sensor to detect a metal object through opaque plastic.
While the radar can only achieve a conical range of approx. 3 km, the RF Detector achieves a dome range of up to 14 km. An advantage of this method of detection. The system is scalable and can be adapted to the requirements and the budget.
Infrared light and radio waves

We can feel the heat of infrared light because its energy is absorbed mostly by the skin. On the other hand, we cannot feel radio waves because these emit their energy deeper in the body, under the heat-sensitive cells of the skin.

Can you “fool” the metal detector? Some people ask if the metal detector can “be fooled”. The answer is no. Unless one tried to pass a metal object around the walk-through detector, or some other subrosa action, the metal detector will do its job.
They detect metal based on electrical conductivity, not magnetism. And even if they did use magnets, the solid-state storage used in smartphones and most other electronics are unaffected by magnetic fields. In fact, many phones now use magnets to charge their batteries.
These scanners are improved so much that they can detect drugs hidden in cavities or the body`s interior. They can see all kinds of illegal drugs and cigarettes in airport scanners. Similarly, they can scan all kinds of liquids or metals through your body or luggage.
Corrosives such as acids, alkalis, mercury and wet cell batteries and apparatus containing mercury.

ANSWER : It sounds like you could have a bad cuircit panel, but definitely try Brand New Batteries, even check them to make sure they have a good charge. Bad Batteries is the #1 cause of detectors not working properly. If this is not the problem than you should contact the factory (First Texas Products) about repairing it. If it is less than 5 years old they will repair it for FREE, even if you are not sure how old it is they have no serial numbers on their products so they can not tell how old they are so they will still repair it for free if you tell them it is less than 5 yrs old. Call them first before sending it in, 915-633-8354
