How to adjust a metal detector? Are you struggling to adjust your metal detector? In this article, you will get a comprehensive guide to adjust your metal detector easily.

You might need some help to get your journey underway using a metal detector. New technologies make for more seamless hunting in recent model metal detectors with customizable configurations.

However, it can be frustrating if you’re not used to these environments. We will provide you with a brief description of all the setups you probably find mostly on a metal detector and instructions on the approach to using metal detector configurations.

How do metal detectors function?

Before know how to adjust a metal detector at first you have to acknowledge that how it functions. Metal detectors operate by transferring a check spindle electromagnetic field to the soil. Any metal object (target) in the electromagnetic field is energetically energized and transmits its own electromagnetic field.

The searching coil of the detector collects the retransmitted region and notifies the user to just an input signal. Most of the metal detectors can distinguish between different target types and therefore can set undesirable priorities to be overlooked.

Pre-set Programs Learning for Adjusting a Metal Detector

Whenever you simply start, your metal detector might include pre-set programs as one of your lifesavers. It is best to leave it up to pre-set programs if you do not want to bother with the hassle of having to fidget all settings.

These applications have been developed for beginners and make switching between modes quick without changing manually any of the parameters. These programs have varying degrees of discrimination and include other sensors to eventually change the system to identify certain object types and metals.

These programs can be tailored to your tastes, but pre-set programs are more often helpful without adjusting the setup. However, you can need to change the settings yourself if you are searching for unique types of metals.

Don’t feel uneasy if you still understand, as we’ll give you a full summary of each parameter. Let’s know how to adjust a metal detector easily.

1.  All-metal-Mode

The all-metal mode could also be used to detect any form of metal, as the name implies. This fits well if you don’t want to separate objects and love hunting instead. That said, if you want to dig up more than waste or don’t want to waste your time searching for a coin, you may want to skip this mode.

When you want to experience various kinds of metal, use the all-metal mode also works well. You will easily say the iron in Gold if you learn how to change the tones, as iron provides a lower tone while gold noises more when it is heard.

2. Corner Fashion

Coin mode can also be used for a preset environment. It does as it looks and works to detect coins by high discrimination.

The iron, foil, nails, and some other small items can record high discrimination. You must note, though, that even this feature will easily make you forget other secret discoveries.

3. Mode of Jewelry

Some devices also have a search feature for jewelry and coins that contains less bigotry, but you also can accumulate some waste that is not useful. Like that, if you start and want to get accustomed to using the system, you would have this mode. We wouldn’t advise it to use it otherwise.

4. Relic Mode

Relic mode is another common mode since it provides you with several discriminatory readings. The mode won’t tell you if small objects are detected and instead shows that a larger object is detected. We will suggest only if you are looking for or recovered artifacts or other items.

5.  Prospecting Mode

A scanning mode for gold is the last form you can see on metal detection.

You would not have to take this mode unless you are in an environment of natural gold. So, if you’ve ordered the metals detector solely to locate gold, we recommend this to no novice.

Settings for the proper adjustment of a metal detector

Possibly a combination of buttons is available, but be careful not to make all metal detectors the same. Although we may not be able to mention those choices your metal detector has, we will do our utmost to explain the options.

Mode: The button mode can be switched to various preset programs.

Sensitivity or Advantage: The sensitivity refers to how much energy the search coil focuses on. 

Key Concepts of Detecting


One of the key features that determine how effectively targets are detected is the frequency of a metal detector. In general, a single frequency detector that sends at higher frequencies becomes more receptive to small objectives and a single frequency detector that sends at low frequencies provides a larger depth to major targets. The VLF and VFLEX innovations of user’s specific frequency.

The world-leading BBS, FBS, MPS, and new groundbreaking Multi IQ platforms from the users simultaneously communicate several frequencies and hence are adaptive to small and large targets simultaneously.

Ground Balance:

Land Balance is a variable setting that improves the depth of detection for mineral soil. Salt, such as in the damp sand of the beach or small iron particles like red earth, may have been in this dirt. These minerals behave similarly to the target to just the transmit field of a detector. The effect of mineralization will effectively cover small objectives due to an over greater landmass relative to a buried objective. The ground balance configuration reduces the reacting earth signals such that target indicators are easily understood and not disturbed by ground noise.

The metal detector consists of three major types:

1. Manual Ground Balance – The ground balance setting is changed manually, ensuring that the least volume of ground signal is heard.

2. Automatic Ground Balance: The detector decides the optimal Earth Balance configuration automatically. This is quicker, smoother, and precise than a ground balance set by hand.

3. Ground Balance Detection – The detector changes continually when you are monitoring the ground balance. The Land Balance is always the correct one and it is ensured.

For superior soil balancing functionality which cannot be matted by any other detector, like many other advanced detectors, minelab detectors are using advanced technology only.

Discrimination is the ability of a metal detector to identify approaching targets based upon their leading and/or iron characteristics. You may opt to dig it up or believe it to be garbage and continue to search by correctly assessing a buried target. Minelab detectors generate target ID numbers and/or aim tones to determine the type of target observed.

In most of the detectors, there are four major modes of discrimination:

1. Vector discrimination – the easiest form of discrimination to adapt the degree of discrimination with a control knife.

2. Iron Mask/Iron discrimination – Used mainly for iron junk gold prospecting detectors.

3. Notch discrimination – Enables the approval or exclusion of particular goal groups.

4. Smartfind – Segregation in the most sophisticated manner. Goal ID is outlined on a two-dimensional (2D) display depending on both iron and conductive characteristics. In order to reject undesirable targets, individual segments or wider screen areas can be shaded.


Metal detector’s most popular question is: How deep are they?

The basic reply is “as deep as that of the diameter of the coil” Thus bigger detectors are sensed deeper.

The detection depth depends, however, both on detector technology and numerous environmental variables. Usually, ‘It depends…’ begins a more complicated response.

I hope this comprehensive guide helped you and now you know how to adjust a metal detector.
