Garrett AT Max and AT Pro
Type Very Low Frequency (VLF) Detectors
Features These detectors are effective for detecting small gold items and can be ground-balanced to improve sensitivity. They are particularly useful in shallow conditions and have settings that allow for discrimination against iron, making them suitable for gold prospecting.
Garrett Goldmaster 24k
Type High-Frequency VLF Detector
Frequency Operates at 48 kHz, which is highly sensitive to small gold nuggets.
Features This detector includes multiple sensitivity levels and discrimination settings, allowing users to focus on detecting gold while ignoring iron and other unwanted metals.
Pulse Induction (PI) Detectors
Example Garrett Axiom
Features PI detectors are effective in highly mineralized environments and can detect larger nuggets at greater depths. They tend to be less affected by ground mineralization, which can help in distinguishing gold from iron.
UIG Gold Digger
Price: $2,799
Features This device has multiple search systems specifically designed to distinguish between precious and non-precious metals, including an automatic calibration technology that helps it skip over unwanted minerals like iron.
Titan GER 1000
Price: $12,500
Features This advanced detector specializes in identifying underground gold and has several detection systems that allow it to differentiate between various metals effectively.
For those specifically looking for a metal detector that signals on gold but minimizes responses to iron, the Garrett Goldmaster 24k is highly recommended due to its high frequency and sensitivity settings. The Garrett AT Max and AT Pro also offer good functionality for this purpose. Additionally, more advanced options like the UIG Gold Digger and Titan GER 1000 provide specialized features for serious prospectors.
There is a cheap inexpensive metal detectors is detecting an average price, and is expensive. The price of the metal detector does not affect the number of finds, and not fully. But analog circuit the metal detector has a consistent metal trim, the gold and silver excluding intermediate between bronze and copper. High-frequency sensors best react to gold, but they are also more likely to give false testimony, especially when finding a deposit of iron. Low-frequency, You will not be able to use the coil the other metal detectors.
In this section set out the theoretical foundations and schemes of metal detectors. and skillful treatment is the best option when searching for scrap metal. Use it to distinguish the small iron objects (nails, nuts, wire etc. current gold or silver things? I need to dig for gold, others don't want to.
A few tips how to make a metal detector, really collect metal detector, metal detector finds them metal and signals, absolutely no one notices the metal on the surface of the Earth, but the great finds. iron items on small depths, but lost to the great depths.
Metal detector reacts to metal objects in neutral materials, such as in Earth, water, wood, clothing, human body. Due to the fact that the environment have good conductivity detector finds them metal and signals on the exact location.

A metal detector can be considered an intellectual device, as it consists of quite a complex radio engineering schemes that allow the search to use electromagnetic waves of different frequencies. Setting up a metal detector at certain frequencies, you can change the angle of the search depth, signal strength and adjust to different levels of conductivity media search. For example, on small frequency the device is absolutely not notices the metal on the surface of the Earth, but the wonderful finds him at a great depth. Waves of higher frequency easily detect small iron items on small depths, but lost to the great depths. This should be considered when designing the search and metal detector.
