History of Fisher Metal Detectors

It was during the late 1920’s a German immigrant by the name of Dr Gerhard Fisher (who studied electronics at the University of Dresden and is founder of Fisher Metal Detectors) obtained the first patent ever to be issued on aircraft radio direction finders while working as a research engineer in Los Angeles. At the time his work had begun to attract the interest of one Dr Albert Einstein who after seeing the equipment demonstrated stated that “radio direction finders would be used world wide both in the air, on land and at sea”.

Although during the early years when direction finders were being used aircraft pilots found that errors would happen to their bearings when a metal object came between the transmitter and receiver or when they passed over certain areas (it was in these areas that highly conductive mineralized formations were found). After carrying out some investigation Dr Fisher found that a portable electronic prospecting instrument could be developed which used the same principles as the direction finders but would instead detect the presence of small buried objects or ore deposits.

He continued carrying out research on this subject and in 1931 he founded the Fisher Research Laboratory (set up in the garage behind his home the infancy of Fisher Metal Detectors). With the assistance of 4 employees he began to produce the “Metallascope”, which was a rugged easy to use metal detector. Although by today’s standards it would have been a very ungainly device consisting of 2 large flat wooden boxes which contained simple copper coils, 5 vacuum tubes and a number of other components. Within a very short period of time not only had it caught the imagination of the people in the USA but also many around the world as well and Fisher Metal Detectors had begun.

In fact by 1936 sales had become so large on the “Metallascope” which had now been nicknamed the “M-Scope” that Fisher Metal Detectors home base, Fischer Research Laboratory, had to move locations and was now being accepted as the standard to which all types of electronic metal detection equipment should be made. Then before the beginning of World War II in 1939 Fisher Metal Detectors moved to an even larger premises and the company was called upon to contribute its technical competence to the war effort both during Word War II and the subsequent Korean Conflict.

Because of the popularity of the M-Scope and because the patent rights Fisher Metal Detectors had on this item was expiring a number of competitors began producing similar pieces of equipment and yet Fisher Metal Detectors managed to maintain their position as they would keep in close contact with clients who used their machines in order to use their wealth of experience to design new models.

In fact over the years Fisher Metal Detectors has designed and produced even more sophisticated products as well as metal detectors such as Geiger counters, Radio Communication Systems, Voltage Detectors and Cable Fault Locators.

Again in 1961 the Fisher Metal Detectors moved once more to a larger production facility in Belmont, California and finally in 1967 Dr Fisher retired from Fisher Metal Detectors after firmly establishing his name in the annals of electronic history. Then because Fisher Metal Detectors continued to grow they moved in 1974 and finally in 1990 Fisher Metal Detectors built their own spacious modern manufacturing plant in Los Banos, California and this is where the world’s oldest metal detector company is now located.

Simplified – how a Metal Detector works

It is believed that the first metal detector was created by Alexander Graham Bell in 1881 in order to locate a bullet that was lodged in the body of the then President of the USA, James Garfield after he was assassinated. However, the first portable version of the metal detectors was in fact patented by a Dr Fischer in 1931 and since then metal detectors have become very common. Below is provided an explanation on the way in which a metal detector works.

1. A metal detector is an electronic instrument which is able to find any instance of metal whether it is in the ground, a human body or inside an object such as a parcel. It is able to pass through, sand, soil, wood or any other non metallic object to find the metal it is looking for.

2. The construction of any elementary metal detector is as follows:- It has an electronic box together with a battery on one side with a handle for the operator to hold it. Then a coil is made from insulated wire which is wrapped around a telescopic shaft and at the end of this is a round plastic disk.

What the operator then needs to do is switch on the power and begin sweeping the ground slowly until an electronic signal sounds or changes frequency. This signal indicates that there is a metallic object or item present under the area where you have just swept with the metal detector.

3. A metal detector works on the principal of using electromagnetism which exerts an effect on metal objects or items. The metal coil on the metal detector is called a transmitter and using the battery power it generates a magnetic field which works on the area surrounding it. When this magnetic field enters the ground it causes any metallic item it comes in contact with to become magnetic and this results in an electronic signal which is detected by the receiver in the coil. The receiver then dispatches the signal it has received to the electronic box which contains a speaker and this in turn emits a beep for the operator to know that metal has been detected.

In each electronic box there is a microprocessor which measures the time lag between charging the area being searched and the electronic box actually receiving the signal. This time lag is known as the phase shift and lets the operator known which metals are present and by using this principle, people are able to configure their high end metal detectors to look for specific metals.

Metal Detecting Treasures Or Trash

Some people think that it takes great skill to operate a metal detector and find treasure buried in the ground. The truth is, it just takes a little practice so that an individual will know whether the object is worth digging or just move because it is just trash.

The metal detector has a built in transmitter, which scans the ground. If something metallic bounces back, the receiver will pick this and send a signal to the user. Since each object has different characteristics, this signal can give the individual an idea of what is underneath.

The first tip that a person should know is how the metal detector works. This device is hand held, so being familiar with the parts and the switches it has will give the treasure hunter a good idea of how to use it.

It would be a good idea to practice using this at home so one will become familiar with the machine before going out into the field.

There are various metal detectors in the market. If the alarm goes off every time, maybe the user should examine the machine being used to determine if it functioning properly. In most cases, there is nothing wrong and the person just forgot to set the notch to only respond to certain objects over a limited area.

The second tip for the avid treasure hunter is to study the manual carefully to understand the type of sounds made by the machine and the meaning of the numbers that appear on the screen.

Scientists and other experts call this method discrimination. This is because it is based on the sound heard, the numeric readout or the meter indicator, enabling the hunter to tell if the object is treasure or trash.

The third tip for metal detecting is that it would be better to conduct a search in a group. This will allow everyone to focus on an item of value so that the focus will not be diverted to anything else. This will lessen the time it takes to scan an area so that the members can move on to something else if nothing was discovered.

Metal detecting can be both fun and challenging. By knowing how the machine works and doing the search in a group, the chances of finding something of value are much higher as more ground is covered.

How to Find Treasure in Your Own Back Yard

You just bought your very own metal detector and you are itching to use it to find some interesting treasures. The only problem is, you don’t have the funds to go to a particular metal detecting hot spot, as there aren’t any within your immediate vicinity. To go metal detecting, you are going to have to wait for the next long weekend, plan the trip, and gather enough funds to spend on it.

The truth is, however, that the answer to your metal detecting woes is already in front of you – or rather, behind you, because you can actually go metal detecting right in your very own backyard. This works particularly well for those who are only starting out with metal detecting and have yet to get a good grasp on the activity. The backyard of your very own home is a great place to practice and learn metal detecting. Plus, it’s the best feeling in the world when you find a treasure right on your own property!

The backyard is best for beginners in metal detecting because usually a backyard is not as overloaded with signals as a lot of other metal detecting places are. It does, however, have enough items and materials hidden in its depths to allow you to learn the signals that your metal detector gives out for particular pieces or types of metals.

Metal detecting in your own backyard is also much cheaper, because it’s practically free! Your backyard also allows you to go metal detecting as often as you want, whatever time or day it is.

Furthermore, metal detecting in your own backyard gives you privacy. Often other metal detecting places will be swamped with tourists or other metal detecting hobbyists. If you are not yet confident with your metal detecting techniques and are only beginning to get the hang of it, the backyard is the best place to start, because no one will see you mess up!

Here are some other tips when you go metal detecting in your own backyard:

1. Go metal detecting after it has rained, when the ground is soaked. The wet soil will enable your metal detector to absorb signals from deeper parts of the ground.

2. With metal detecting, patience is very important. For every treasure or valuable item you find, you would’ve stumbled upon a dozen other items that are totally useless. It’s all about being patient and looking really hard.

So start metal detecting now! Who knows what kind of treasures you’ll find in your own backyard?

Best Gold Metal Detector Review

Gold mining must have been a nightmare in the 1800’s, where people panned for gold for months only to find small flakes of gold or give up before finding any. In this age of advanced technology, gold prospecting technologies using gold metal detectors have come a long way in ensuring that before embarking on mining, gold miners know exactly the amount of gold they will get.

A gold metal detector is specifically made for gold prospection. They are exclusive to gold detecting and do not pick signals for other metals, unlike regular metal detectors. The standard gold metal detector uses Very Low Frequency (VLF) or Pulse Inductioncircuits to detect gold and filter out all the other metals in its magnetic field.

The major investment you make in gold prospecting is purchasing a quality gold metal detector. Having a good gold metal detector is a great stride towards success. There a variety of gold metal detectors and some review of those detectors will have you well informed before purchasing one.

Types of gold metal detectors

They are generally two types of gold metal detectors, based on their mechanism for detecting gold;

  • Very Low Frequency (VLF) gold metal detectors
  • Pulse Induction (PI)gold metal detectors

Very Low Frequency fold metal detectors

As the name suggests, these detectors use very low frequency circuits to detect gold nuggets. Some of the popular models in this category are

  • Fisher Gold Bug Pro
  • Fisher Gold Bug 2
  • White’sGoldMaster GMT
  • Garret AT Gold
  • Tesoro LoboSuperTra
  • Minelab Eureka Gold

VLF gold metal detectors greatly pride in their ability to detect very minute nuggets of gold. In hands of an experienced user, these detectors beat their Pulse Induction counterparts in detecting small sized nuggets.

VLF gold metal detectors are quite affordable compared to pulse induction detectors. It is possible to find a new VLF detector for less than $ 1000, or even a second hand but in-shape detector for a few hundred bucks.

They are relatively light, which makes carrying them around less of a hard task.

On the other hand, VLF gold metal detectors have their shortcomings, the main of them being their inability to detect gold nuggets lying deep. They can only detect gold nuggets at a maximum depth of 12”, a factor that greatly cripples their success if the nuggets are lying deeper than that.

VLF gold metal detectors cannot detect nuggets in highly mineralized ground and very hot rocks, the common surrounding of gold nuggets. This problem is solved by proper tuning, reducing sensitivity to a point it can only detect a very limited depth.

Here is a quick review of each of the VLF gold metal detectors;

Fisher Gold Bug 2metal detector

It has an easy mount system, with a single button push firmly mounting the control box to the stem. It also has easy to access rechargeable batteries, making recharging them easy.

It is a lightweight weighing 2.6 lbs.

Pulse Induction gold metal detectors

Some of the common PI gold metal detectors are

  • Minelab GP and SD metal detector models
  • White’ TDI Pro
  • White’s TDI

Pulse induction gold metal detectors are considered superior to VLF detectors, due to their ability to detect gold nuggets at great depths. They can detect small to medium sized nuggets but not small flakes.

They are also able to detect gold nuggets on hot rocks; hot rocks do not tamper with their efficiency.

Pulse induction detectors have superior ability to ignore conductive and non-conductive ground mineralization and still maintain high sensitivity to target metal/metals and in this case gold.

Gold metal detectors in this category are quite pricey, going for well over $5000, which most likely screams quality.
