Metal detecting has come a long way from simple metal sensors to advanced technologies that allow hobbyists and pros alike to find treasures more efficiently. One of the game-changing innovations in recent years has been the development of multi-frequency metal detectors. If you’re curious about what multi-frequency means and how it can benefit your detecting adventures, this guide is for you.
What is a Multi-Frequency Metal Detector?
Put simply, a multi-frequency metal detector operates on more than one frequency simultaneously. . Traditional single-frequency detectors use only one frequency commonly somewhere between 5 kHz and 50 kHz which can limit their performance in certain ground or target types. Multi-frequency machines blend multiple frequencies to offer better target detection and separation.
Why Choose Multi-Frequency Technology?
Better Ground Adaptability
Different soils affect metal detecting differently. Mineralized soils, saltwater beaches, or highly trashy areas can confuse the detector. Multi-frequency technology helps overcome these challenges by allowing the detector to be optimized for a wider variety of conditions.
Enhanced Depth and Target Separation
Multi-frequency detectors can penetrate deeper and detect smaller targets more accurately, particularly where mineralized soil is encountered. They also do a better job of distinguishing valuable finds from junk metals, saving you time digging up trash.
Versatility Across Target Types
From tiny gold nuggets to relic coins and jewelry, multi-frequency detectors are designed to handle diverse target sizes and metals effectively. This versatility makes them the perfect choice for serious prospectors and treasure hunters.
Garrett Metal Detectors with Multi-Frequency Capabilities
Garrett offers several multi-frequency metal detectors that combine user-friendly features with powerful technology.
- Vortex series: Each of the three Vortex detectors in this family are fully submersible to 16 feet, and offer both single and multi-frequency operation choices.
- ACE Apex: This rainproof detector offers both single frequencies, a true multi-frequency, and a Multi-Salt multi-frequency option for searching saltwater beaches.
- Axiom Series: Garrett’s pulse induction multi-frequency detectors provide deep detection power, especially suited for finding gold highly mineralized environments.
How Does Multi-Frequency Work in Practice?
The detector emits multiple signals that travel differently through the ground. Some penetrate deeper, while others are more sensitive to smaller metals. The detector’s internal processor blends those signals into clearer information about what lies below and whether it’s worth digging.
Accessories to Maximize Your Detector’s Performance
Using the right accessories can enhance the benefits of multi-frequency detectors. Garrett offers a variety of search coils in different sizes and types tailored for specific ground conditions and detection goals. The Z-Lynk™ wireless headphone system helps isolate target signals from ambient noise, giving you a sharper, distraction-free audio experience.

Frequently Asked Questions
Q: Are multi-frequency detectors harder to use?
A: Not necessarily. Many modern detectors, like Garrett’s Vortex VX9 and ACE Apex, offer intuitive controls making them easy for beginners while still appealing to pros.
Q: Do multi-frequency detectors drain batteries faster?
A: They can consume slightly more power, but most come with efficient battery solutions and indicators to help you manage energy use.
Q: Can multi-frequency detectors find gold better?
A: Yes, in highly mineralized soil, multi-frequency operation can provide better Target ID.
Q: Will multi-frequency tech work better on saltwater beaches?
A: Absolutely.Garrett’s ACE Apex and Vortex VX7 and VX9 each have Multi-Salt multi-frequency options that filter out the unwanted effects of salt and other challenges found on wet saltwater beaches and in shallow saltwater.
