Mineral exploration is a craft that has been practiced for many years. Nowadays, there are high-quality professional devices that greatly facilitate the task itself and make the whole process much more efficient and shorter. The device known as Pinpointer is one of them.
What is an Pinpointer?
A precision indicator is a portable metal detector used to determine the exact location of a metal object detected by a larger metal detector. They are small, lightweight, easy-to-use devices that are usually held with one hand and are used to scan areas where a particular metal object is thought to be present.
How does it work?
The process of making this type of device is done by using a small metal coil inside the device to generate a magnetic field known as a coil. When the coil approaches a metal object, the magnetic field breaks off and the pointer detects the change in the magnetic field. This outage is detected by a sensor in the device, which then sends a sound or vibration signal to alert the researcher.
Types of indicators and how to choose the best one for you?
Several types are available on the market, each with its own characteristics and main advantages. Here are some common types, most of which you will find here:
Acoustic indicators – These devices emit an audio signal when metal is detected. It is very popular with beginners and those who prefer some kind of sound to indicate the presence of metal.
Vibration – This type of Pinpointer vibrates when metal is detected, making it ideal for use in noisy environments or for those who prefer silent signal;
Sound and vibration – These models provide an acoustic signal and vibration when metal is detected, providing flexibility in different environments;
Waterproof (underwater) – It is designed to be completely waterproof and can be used in water up to a certain depth. They are suitable for use in rivers, lakes or other bodies of water;
Frequency change indicators – This type of device can change frequencies to reduce interference from other metal detectors, making it suitable for use in densely populated areas;
Multifunctional – This type offers additional features such as LEDs, fine resolution and different levels of sensitivity, providing more flexible functionality.
To choose the best option for your needs, consider the following factors:
Alert type – Select whether you want sound, vibration, or a combination of both alerts;
Water resistance – if you plan to use the device in or near water, choose a model that is completely waterproof;
Sensitivity – Find a model with adjustable sensitivity settings so you can customize the device to your specific needs;
Battery life – Consider the battery life of your Pinpointer, especially if you plan to use it for long periods of time.
What is the difference between a micro indicator and a metal detector?
Pinpointer and metal detector are two different tools used for metal detectors. They have several important differences:
Size and transportability – the indicator is smaller than a metal detector. They are usually hand-held and can be easily carried in a pocket or on a belt, while metal detectors are larger and require more space for storage and transportation;
Accuracy – Some are designed to be used with metal detectors to determine the exact location of a metal object once it is detected. Metal detectors, on the other hand, scan a wider area to detect metal objects.
Usage – Indicators are commonly used to locate small or deeply buried metal objects, such as coins, jewelry, or antiquities. Metal detectors are used in a wide range of metal detection activities, including treasure hunting, gold excavation and archaeological search.
How to use Pinpointer – step by step
Here are the steps to use Pinpointer:
Turn on the indicator and hold it close to the ground to calibrate it.
Move the metal detector over the area you want to search for until you get a signal indicating the presence of metal.
Once you find some type of metal, such as a gold block, using a metal detector, slowly move the pointer over the area where the signal was detected until you hear the pointer sound or vibrate, indicating the presence of the metal.
Gradually move the cursor near the metal object until you find its exact location.
Once you find the metal object, use the precision tool to drill around the object.
Maintenance and storage
Here are some tips for maintaining and storing your device:
After use, wipe the Pinpointer with a soft, dry cloth to remove any dirt or residue;
Avoid using harsh chemicals or abrasive cleaners that can damage them;
Remove the battery from your device when not in use to prevent corrosion;
Store the unit in a cool, dry place that is good and suitable, away from direct sunlight and moisture.
What should you pay attention to when using it?
When using this particular device, it’s important to pay attention to a few basic things that include:
Avoid using it near power lines or other sources of electrical interference, as this may affect its accuracy;
Be careful when placing it on the ground, as hitting a solid object can damage it;
Do not immerse your Pinpointer in water deeper than the estimated depth as this may damage it
Follow all local laws and regulations relating to their use, as some sites may prohibit these tools or require permits for use;
Use your Pinpointer responsibly and respect the environment by filling in any holes you drill and not disturb protected areas or artifacts and cultural remains.
