We also like the depth reading - it can detect items at 6”-8” deep, or up to 9” in the right soil conditions.
The metal detector is also built to allow you to set your own tones plus it has non-volatile memory saves settings for ease of use.

How To Choose The Most Accurate Metal Detector?
This feature refers to the ability of a metal detector to detect conductive materials from a specific distance. Each sensitivity level is perfect for certain applications, so it is important to determine what you’d like to detect – a relic, coins, gold, or jewelry – and the desired depth.
Take note that the required sensitivity level might need to be changed due to the mineral content in the search area.
Find a metal detector with adjustable sensitivity levels is better for you to hunt on different soil conditions.
Discrimination & Target identification
Discrimination is a function that helps a metal detector distinguish between various material types (such as between bottle caps and coins), and it affects the accuracy of the tool.
Meanwhile, target identification boosts that function to the next level. It can tell you exactly what the object is (usually distinguishing between coins of different denominations, gold, jewelry, and junk) within a certain range.
Note: Discrimination function might not come in handy for relic hunters.
Only some metal detectors have a ground balance feature – which helps reduce false alarms due to interference of metals and metal alloys in the soil on the tool’s ability to locate conductive materials.
There are four types of ground balance:
Multiple ground balance – the feature that allows for either manually or automatically setting the ground balance level.
Manual ground balance – the feature that allows you to change the ground balance level due to the desired target
Preset ground balance – the feature that allows you to choose between pre-programmed settings to adjust the ground balance level due to your needs and desired target.
Automatic ground balance - the feature that automatically adjusts the ground balance level to detect and adjust for interference.
Which Brands Make The Most Accurate Metal Detector?
In metal detection, this is one of the most trustworthy names. It was established in 1931 and through the years, they have developed a wide range of lines using their own technology and innovation – which is the reason for their outstandingly quality products.
Founded in 1964, Garrett is another reliable brand in manufacturing metal detectors and selling them at highly competitive prices. They also set a new standard on unparalleled customer satisfaction.
Quest was set up by a group of professional and experienced detectorists. They are dedicated to providing metal detectors and related accessories that use cutting-edge technology.
Are cheap metal detectors any good?
Yes, they are. Low-budget, cheap metal detectors are made mostly for beginners but rest assured, they can give great performance and quality.
Are Garrett metal detectors any good?
Yes, they are. Garrett metal detectors are deemed some of the best picks for people who intend to get into the hobby due to their top-notch quality, accuracy, and performance.
Is Minelab better than Garrett?
While they are both well-known metal detector manufacturers, their products are aimed at different groups of users.
Minelab metal detectors are mostly for pro relic hunters while Garrett’s are well-loved by beginners and intermediate-level relic hunters.
How deep can a metal detector detect?
A metal detector mostly can detect objects from 4” to 8”. While some specialized models can go deep to 65’ underground - especially in ideal conditions, the mid-range ones can reach 12” to 18”.
Can you find diamonds with a metal detector?
No, you can’t. Diamonds don’t contain metal. But if you want to find diamond rings, a metal detector can help you.
Purchasing the most accurate metal detector is a challenging yet fun task. It is an essential piece of gear that will make or break your relic hunting game. Whether it’s the ease of use, decent discrimination function, or weatherproofing, we have got the best options to help you find the right one.
