Right now, only own a small arsenal of VLF detectors that get used. Since building my PI's, there has been a tendency to grab it and go hunting. PI detectors are more or less are niche specialty machines. Used mostly for gold prospecting, gold jewelry hunting in the water and beach, relic hunting.
the project was to develop a man-portable neutron detection system that has the ability to determine the direction of the source from the detector. The efficiency of GaAs detectors for different sizes of polyethylene layers and different angles between the detector and the neutron source were determined. Preliminary measurements with a

A typical metal detector used for detecting buried coins, gold, or landmines consists of a circular horizontal coil assembly held just above the ground as shown in the figure to the right. Other uses of more specialized metal detectors include usage in medicine, security etc. Metal detectors have been used for diagnostic purposes since 1881.
For this metal detector project, we will be using an Arduino to process the oscillation signal instead of offsetting the oscillation with a second tank circuit. The Arduino will store the fixed frequency and continuously compare the incoming frequency of the detector circuit with the stored frequency (more on the Arduino program below).
Metal detector is a device used to detect the presence of a metal in its proximity without touching it. This project explains the concept of detecting the presence of a metal using the method of inductive sensing.The basic concept used is that the presence of a metal can vary the inductance value of …

In this project we are going to design a simple metal detector circuit. There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 Timer IC.
Jul 22, 2013· Diy Arduino based metal detector. UPDATE: Try using BC547 as transistor people have reported problems with 2n2222. Me and my son decided to go treasure hunting with a metal detector that we have but we couldn't find it anywhere.
The typical amateur treasure-hunting metal detector can only detect metal objects one or two feet below the surface. and the wand detector. antipersonnel mines are harder for metal detectors to locate because they are often made of plastic. prospecting for gold and/or silver.
Best Underground Metal Detector Professional gold and diamond metal detectors headphone charger individual box package Hot Sell under ground gold detector/long range metal detector with discrimination and LCD Display Underground Metal Detectors Can Be Distinguished From Copper And Silver Gold Pattern Selective Detector
Feb 03, 2013· My detector was designed for general purpose hunting with the ability to find small gold normally found with PI's in the 10us range. The base platform used was Carl Morelands Hammerhead PI. The Hammerhead PI was designed to be used as a learning platform that could be modified to any number of configurations for those willing to experiment.
be varied by a metal detector operator varying the controls of the metal detector. Most discriminating metal detectors also have a visual display which indicates properties of a detected metal target. Figure 1. Transmit signal, receive X and receive R at the receive coil, X magnitude, R magnitude.
The GPA 3000 set contains the GOLD SCAN II gold detector, which also is newly developed. The device comes with a waterproof 25 cm (9.8") searchcoil, the 1 x 1 m searchframe and the fitting charger. The gold detector GOLD SCAN II discriminates gold from other metals and indicates the scanned metal type on the display.
7. The Velleman K7102 Metal Detector Project. To build this DIY metal detector, you need Velleman K7102 kit, solder, a buzzer, a 9V battery, and some tools. There are instructions to help you solder the components in place and do everything from making the coils to testing the detector.
Here are some Metal Detector Projects that are quite interesting for the purpose of education and experiments in the Art of electronics. This site may be as old as Y2K, but the url / …
Home Made Metal Detector Interested in building an extremely difficult project to help you find more gold nuggets and still save some significant money in the process?If you know what you are doing, do it right and plan well, it is possible that you really can save a lot of money.
Carefully place the gold in a pile on a clean sheet of paper in a location where there is no other metallic object reading on your detector. Scan the gold with your detector from varying distances to get an idea of your distance-capabilities when scanning a concentrated gold deposit.
Technology and design issues relating to metal detectors and other treasure hunting instruments, includes projects and a discussion forum.
Most gold prospecting detectors feature manual ground balance controls. This feature will allow the machine to be adjusted to filter out the general iron content of the ground. Don't be intimidated by the need to ground balance, after you have done it once or twice, it will become second nature.
Jan 11, 2010· To build a metal detector, start by getting a portable AM/FM radio and a Then, tune the radio to the highest band on the AM setting. Next, turn on the calculator and …
The smart metal detector is a device that used to detect metallic material such as coins, gold and other metal items. It can move and change the direction of movement in certain situation to scan the underground metal.
Turn your radio on, and try the metal detector out on any type of metal. You will notice that the calculator beeps whenever you get close to metal. It beeps even faster the closer you get to the metal.
