Metal detector numbers indicate the strength of the electromagnetic field, helping identify metal objects buried beneath the surface. The numbers on a metal detector show how close and big a metal object is underground. Have you ever been curious about those numbers you see on your metal detector’s screen? You’re not alone!
Metal detectors are tools that help people find treasures or ensure security. But understanding what those numbers mean is really important to use your metal detector well.
In our previous blog, we discussed What does disc means on a metal detector. Which is very helpful to find treasures, not trash.
In this article, we’ll explain what those numbers on your metal detector are all about. Whether you’re just starting or you’re an experienced treasure hunter, this guide will help you understand this important part of using a metal detector. Let’s get started!
What do numbers on a metal detector mean?
The numbers on a metal detector typically represent its sensitivity or discrimination settings, depending on the specific model and manufacturer. Metal detector numbers are like a secret code on the detector’s screen.
They tell you what kind of metal is hiding underground and how deep it might be. Low numbers mean it’s probably iron, while high numbers suggest something more exciting, like coins or jewelry.
These numbers are your treasure map, helping you decide if it’s worth digging. So, when you’re out hunting for hidden treasures, keep an eye on those numbers to unlock the secrets of what’s buried beneath the soil.
How to read your metal detector?
To read your metal detector, first, turn it on and let it calibrate. Adjust the sensitivity and discrimination settings based on your preferences and the type of metal you’re looking for. Swing the detector coil close to the ground in a sweeping motion, listening for beeps and watching the display.
When you hear a consistent signal and see a strong reading on the display, stop and pinpoint the target by moving the coil in smaller circles.
Dig carefully to unearth the metal object, and remember to respect local laws and regulations regarding metal detecting.
The Science Behind Metal Detector Numbers
Metal detector numbers are like a secret code for treasure hunters and archaeologists. These numbers tell us what’s buried underground. When we scan the ground, the detector measures how well things conduct electricity. Some things, like silver or copper, conduct electricity well, giving high numbers on the detector.
Other things, like iron, don’t conduct as well, so they give lower numbers. Understanding these numbers helps us determine if we’ve found something valuable or just some old junk. It’s like a metal detective’s tool to find hidden treasures and ancient things. Those numbers on the detector are like a map of the past!
The Importance of Reading numbers on a metal detector
It’s really important to read the numbers on your metal detector when you’re out looking for stuff. It’s really important to understand the numbers on your metal detector for a few reasons:
- Find out What’s Buried: The numbers can tell you if you’ve found something valuable or just junk. This helps you focus on the good stuff.
- Figure Out How Deep: Some detectors show how deep the object is. Knowing this helps you know how deep to dig.
- Tell Trash from Treasure: The numbers can help you tell if it’s something worth digging up or just something you can ignore.
- Adjust the Settings: You can use the numbers to change the detector’s sensitivity, so it works better for different situations.
- Learn About History: Sometimes, the numbers can give you hints about how old or where the thing came from.
- Stay Safe: Understanding the numbers helps you avoid damaging what you find and helps protect the environment.
- Get Better: Reading these numbers regularly makes you better at finding cool stuff with your metal detector.
So, paying attention to those numbers is super important for having a successful and respectful treasure-hunting adventure.
How to know what metal detector numbers mean?
Metal detectors have numbers on their screens. These numbers show what’s under the ground. Smaller or less conductive things have lower numbers, like nails. Bigger or more conductive things have higher numbers, like coins.
The numbers also show how deep something is. It’s important to learn what these numbers mean, which you can find in the manual. This helps you find valuable stuff and avoid useless things when you’re treasure hunting.
What is the maximum range of a metal detector?
The range of a metal detector varies depending on its type and purpose. Regular handheld or walk-through metal detectors used for security typically have a range of about 6-12 inches (15-30 centimeters). These detectors are meant for close-up scanning to ensure accurate results without detecting objects too far away.
On the other hand, specialized metal detectors, often used for treasure hunting or archaeology, can have much greater ranges. Some advanced models can detect metal objects buried as deep as 10-15 feet (3-4.5 meters) underground.
For instance, the Minelab GPX 5000 is a professional-grade metal detector known for its ability to find valuable relics and treasure buried at significant depths.
In summary, the maximum range of a metal detector depends on its intended use, and different models are designed for various applications with varying detection capabilities.
The metal detector number chart
The Metal Detector Number Chart is a simple tool used in security and industry. It has numbers from 1 to 10, each representing different types and sizes of metal objects:
- 0 – Iron, since you can find it anywhere
- 0-8 – Foil made of regular metal
- 28 – Nickel coin worth 5 cents
- 35 – Gold coin worth $2.50
- 45 – Silver coin worth 3 cents
- 50 – Gold coin worth $5
- 70 – Gold coin worth $20
- 82 – Silver quarter
- 90 – Silver dollar coin
This chart helps people quickly identify what a metal detector is detecting, making security and inspections easier.
