Is there a difference between metal detectors?
When you start practicing metal detection, you will always start with a regular all-purpose device. You may want to start with an expensive detector, but most likely, it will still be designed primarily for coins, relics, and some other precious metals… After a while, you will discover that there are other types of devices, called gold detectors, that are specially designed for high value things like gold, so there is a difference.
So, what is the difference between a metal detector and a gold detector anyway? The typical detector is generally designed to operate at low frequency for collecting coins, relics, and metals of large size and conductivity. Gold detectors can operate at high frequencies in difficult ground conditions by picking up gold even in small sizes; It can also do a great job of distinguishing metals.
In this article, we will provide all the details you need to know about the differences between the two devices. We will also give you some practical examples of detectors commonly used by some hobbyists with decades of consistent experience. Thus, you will have a complete idea about it, which not many people who take up this hobby actually have.
Key Differences Between an Ordinary Metal Detector and a Gold Detector
Multipurpose gold and metal detectors have pretty much marketing names! We mean the names remain meaningful, but they are generally used to make it easier to understand the general usage of each.
If you ask the detection experts they will tell you right away that there are two different types of devices:
VLF (Very Low Frequency) detectors – more adapted to coins, relics and general metals.
PI (Pulsed Induction) Detectors – adapts to gold even in harsh soil conditions.
When we say gold machine; It is still a general term to distinguish between a good prospecting machine and a typical coin or jewelry detector. Make sure all metal detectors detect all metals, but some do a better job than others for certain types of exploration.
Frequency and target size:
Gold detectors operate at a higher frequency than their counterparts. It is these high frequencies that gold responds to, and this allows the detector to easily pick up those very small targets of low conductivity.
In general, all detectors can pick up gold, but not like those designed specifically for gold. The higher the frequency, the better to find smaller targets with higher conductivity, and this also includes iron.
Most gold detectors filter iron, but they beep at any other low conductor. You will also discover high conductors.
Gold detectors often use slightly different technology than standard detectors. This makes it great for detecting gold, but not so good for non-gold items. However, since gold is so highly valued, many people are happy to focus solely on it, especially in well-known gold spots.
It is not that other metals cannot be found. AT Gold for example will help you find tons of metals for sure. It is just what suits it best.
On the other hand, regular machines will be useful for those interested in history. Those who wish to uncover coins made of silver and bronze. Also, if you are interested in discovering things like bullets, ammo, copper wire..
In general, the file size of the gold detector is smaller than average! This allows it to be sensitive to small targets which is excellent for gold. The latter usually weighs less than a gram.
In fact, the smaller the coil, the smaller the metal it will detect!
The only problem with the small file in general is the depth! Because this will not allow you to find targets that are too deep underground.
Gold detectors do not have a very high depth, especially if they are equipped with a single-layer coil. But for those with a DD (Double-D) coil, the depth can be a little higher.
The answer to that is very quick and clear, gold detectors are much more expensive than VLF detectors. WE do not really want to talk about some of the specific prices because they vary a lot by country, retailer, and the current season.
Gold machines are generally heavier than normal detectors! But there is not much difference…for example, the Bounty Hunter is less than 2lbs but for a Minelab Gold Monster 1000 it weighs about 6lbs. In general, We can say that PI detectors are 2-3 times heavier than VLF devices.
Just buying machines dedicated to gold “no” means that you will find gold immediately. That’s when the experience comes and it may take years to learn the techniques of hunting small pieces.. Hunting and the skill of a block is completely different in metal detection.
As far as the learning curve is concerned, this depends on how advanced the machine is. There are some VLF detectors with a difficult learning curve.
Do you own a multi-purpose device or a gold metal detector? Which brand exactly? If not, what kind of machine would you like to own in the near future? And why?
Finally, knowing the difference between these two devices is not enough! You also need to know the correct places where you should use your device! This is the key to success and capturing as many discoveries as possible. In addition to patience and nothing but patience!
