Understanding Multi Frequency Metal Detectors


Understanding Multi Frequency Metal Detectors


by Michael Bernzweig

Multi-frequency metal detectors are the best for most users, as they offer greater versatility and sensitivity than single-frequency models. These devices can switch frequencies, which helps discriminate between different types of metal. This is especially useful for prospectors searching for a specific type of metal, such as gold.

The difference between single frequency, multi-frequency, and pulse induction metal detectors is the technology they use to identify metal objects. Single-frequency metal detectors emit a single pulse of electromagnetic energy into the ground and then analyze the reflection of metals. Single-frequency devices like VLF detectors usually function at 10 kHz per second or lower and 30 kHz per second or higher.

Multi-frequency or simultaneous multi-frequency models also emit pulses, but they do so at multiple frequencies. This helps to better discriminate between types of metals. Pulse induction metal detectors or PI detector work by emitting short bursts of energy into the ground and then measuring the time it takes for the reflections to return. This article will focus on the best multi-frequency metal detectors on the market.

The Best Multi Frequency Metal Detectors

Metal detecting is a great hobby that can be enjoyed by people of all ages. It's a great way to get outdoors, explore new places, and find hidden treasures. One metal detecting tip is to use a multi-frequency metal detector. There are many different types of metal detectors on the market, but the best metal detector type for most users is the multi-frequency metal detector. These devices offer greater versatility and sensitivity than single-frequency models.

There are many different brands and models of multi-frequency metal detectors on the market, so it can be tough to know which one is right for you. To help you decide, we've compiled a list of the best multi frequency metal detectors currently available.

1. Nokta Makro Legend

The Nokta Makro Legend is one of the best metal detectors and Nokta's first VLF detector, which is a simultaneous multi frequency detector. It is loaded with features that make it the best multi-purpose detector, adaptable for all types of targets and ground conditions.

Not only does the Nokta Makro Legend have silence and stability in operation as an underwater metal detector and on the beach with a waterproof search coil, but it can also sift through trash easily to get what you're looking for. In addition, this device is great for gold prospecting as it can pick up small nuggets of gold in densely mineralized areas and has 60 target IDs & harmonic tones.

2. Garrett Ace Apex

The Garrett Ace Apex is a new multi-frequency waterproof metal detector that offers ultimate versatility. Apex's waterproof dd search coil means you can use it in the rain or shallow water. Waterproof coils are great for beach hunting as well.

Garrett's Multi-Flex technology uses a cutting-edge, broad-bandwidth digital platform to give you more versatility with the Apex than any other detector in its price range! You can choose from powerful single frequencies or select one of Apex's simultaneous multifrequency modes for excellent detection across all targets and soils.

For large and highly conductive metal objects like silver coins, a lower frequency mode is often more effective. On the other hand, a higher operating frequency mode is generally better at detecting smaller pieces of metal that aren't as conducting, such as hammered silver coins or gold nuggets. The Garrett Ace Apex is also compatible with Garrett's wireless headphones (sold separately), so you can hunt in noisy areas without missing a beat.

3. XP Deus II

The XP Deus II is a top-of-the-line simultaneous multi frequency metal detector that offers excellent performance and versatility. It features an LCD, wireless audio capability, and a waterproof search coil.

Metal detection with the XP Deus II offers:

  • Ergonomic & lightweight machine
  • Fully wireless experience
  • 4 > 45 kHz multi-frequencies
  • Waterproof up to 66 Feet (20 Meters)
  • Notch discrimination
  • Advance ground balance features
  • Waterproof coil, LCD display, and coil cover

XP offers related products like wired headphone options, the first bone conduction headphones designed for metal detecting, known as BH-01. There are also multiple wireless low latency headphones, including WSA II and WSA II XL. The technology used in the wireless headphone is patented.

The DEUS II is great for use on the beach or in the water, but it's also excellent as a gold metal detector. It is a multi frequency metal detector perfect for finding small nuggets of gold in densely mineralized soil. The DEUS II discriminates between a metal object like iron and stainless steel that is detected at lower frequencies to objects like gold jewelry and nuggets that register at higher frequencies.
