How deep can a metal detector detect?

A metal detector penetrates the earth’s magnetic field to detect metals. Different metal detectors have different depths in which they can detect. This is dependent on so many factors, which may be classified as internal and external factors.

1. Internal factors

There are factors related to the detector itself. The size of the coil is one of the internal factors that significantly affect the depth of detection. Detection depth is directly proportional to the size of the coil. A larger coil will, therefore, detect deeper.

Note: a coil that is too large compromises accuracy and sensitivity.

The type of technology used in detecting metal determines how deep you can catch. Some

detectors have beat frequency, while others have pulse induction. Pulse induction detects deeper. The effect of mineral salts is also minimized.

The frequency of the detector – different detectors come with varying frequencies. The lower the frequency, the deeper it detects and vice versa.

Note: low-frequency compromises sensitivity

2. External factors

These are factors not related to the detector itself. Ground terrain is one feature that you cannot ignore if you want to detect deep. The slope affects how much the metal target is buried, which affects the distance between the detector and the target.

The depth of the metal that is being detected also affects how deep the metal detector can detect. In addition to depth, the size of the treasure is also important. Bigger objects are detected deeper.

Different metals have different conductivities. More conductive metals are detected deeper. Where the ground is deeper, the chances of objects being buried deeper are higher.  Soil compatibility is of the essence. The amount of minerals present is of effect.

Though the manufacturers give certain depth guides for each detector, it is clear that they are not guaranteed due to the external factors that detection depth depends on.

How to repair a metal detector?

When using any machine, learning how to fix it is very important. Repairing a metal detector is an essential skill that will help you avoid additional expenses of repair. It also ensures a frustration-free search.

1st Step

Non-functioning search heads – in most cases, search heads fail to function when mud and dirt are sticking on them. WD40 is a very effective solution in which, when applied, it becomes easier to remove the dirt.

Failing to switch on and off – ensure that the batteries are put in the right way. It is also good to try other batteries to ensure that the problem is not in the battery. Where the search head is removable, ensure that it is plugged in properly.

Note: remove the batteries when the detector is not in use to avoid battery-related problems.

2nd Step

No sound – first, check to see that the volume is turned on and the adapter of the headphones is not left in the detector after unplugging. If it does not work, wipe the jack and the headphone plug with a swab dipped in distilled alcohol.

3rd Step

False signals and Noisy detector – this is most of the time caused by electrical interference. First, try searching for the metals around 200 m from where you are. If it is still noisy and is not blocking false signals, reduce the sensitivity using the knob. (where applicable)

4th Step

Wet metal detector – most metal detectors are partially waterproof. However, it may accidentally be immersed in water. The first step is to remove the batteries immediately.

This is because water is a good conductor of electricity and will short circuit the components. If the detector is immersed in freshwater, keep it warm for a few days, and it will begin functioning.

Note:  if it is accidentally immersed in salty water, contact the customer service of the detector if you are unable to open the control box to dry it manually. This is because saltwater is corrosive.

5th Step

Non-functioning LCD – this may be due to static charges on the surface. Using a damp cloth, wipe the screen twice.

Most of the problems that arise when using metal detectors do not need any technical repair. They result from simple mistakes, mix-ups, misunderstandings, or inaccuracies by the user.

How to choose a metal detector under 100 dollars?

How to choose a metal detector under 100 dollars

They say cheap is expensive in markets, but this is not the case in metal detectors. Contrary to the phrase, you can still get a very efficient metal detector with quality and necessary features.

With the advancement of technology in the manufacturing sector, so many models of metal detectors have emerged in the market. Most of them have been equipped with features aiming to improve competency but, on the other hand, compromising affordability.

When selecting a metal detector, there is some crucial feature that one should put into consideration.

Search for the best

With one hundred dollars or less, one can get a metal detector not damaged by water. The waterproof feature allows you to use your detector in wet places like beaches, streams, and other shallow areas.

It also allows you to search for treasure when it is raining. The 8-inch coils ensure that high accuracy and hardly miss any details. On the other hand, a detector that is not partially waterproof is very limiting in harsh weather conditions.

In some cases, there are those metals you want to find and those you don’t. This is where the two-mode feature comes hand in hand.

This setting enables you to eliminate targets that you do not want to find. For instance, you can eliminate zinc and iron. There is also the all-metal mode whereby all metals are detected.

This saves time and ensures that you do not dig with excitement only to find a metal that you are not interested in.

Ground control is a feature that minimizes interference from external signals. This ensures that the metal detector does not raise false alarms due to detecting other metallic minerals in the soil.

It is, therefore, an essential feature as it saves you from getting excited when you have not found what you are looking for. The tone in metal detectors alerts you when the signal is detected.

It should have a high volume to ensure effectiveness even in noisy environments. Some metal detectors are installed with LCD screens which are not necessary, especially for kids, as they may be difficult and unnecessary to read.

With the two-tone mode, the detector produces the high and low signal for precious and non-precious metals, respectively. Too small a search coil reduces the ability of the metal detector to find the target.

On the other hand, when the search coil is too large, accuracy is compromised. It is therefore vital for you to ensure you find a metal detector with a standard search coil. The ground balance also complements the ability of the sensor to see its target as it blocks unnecessary signals.

The adjustable stem is a feature that ensures that either kids or adults can use the metal detector. It allows you to adjust the length by the height of the user. One is therefore comfortable as you do not have to bend too much or strain with the size of the handle.

Final Verdict

As we have seen above, metal detectors can be found at different prices. Users can easily find the best metal detector under $100. This detector is incredible and offers almost all the functions that you could find in other metals.

With all features, your metal detector will work just as well as that expensive metal detector. It can detect a gold ring, copper, and silver. It is, therefore, possible to find an efficient but also affordable metal detector.

Moreover, there are some cases where buying expensive metal detectors would be unnecessary. With a cheap metal detector, you will not lose a lot of money.

Secondly, beginners prefer this metal detector as they do not have complicated features that will course difficulty using it.

Also, when you need to use the detector once, this metal detector is economical. You, therefore, do not need to spend more than a hundred dollars on metal detectors.
