Single Frequency vs Multi-Frequency Metal Detectors (+ Best Value Picks for 2026)
Choosing the right metal detector can make the difference between finding treasure and going home empty-handed. One of the biggest decisions is whether to go with a single-frequency detector or a multi-frequency detector.
In this guide, we’ll compare three excellent options available now at Big Boys Hobbies — including a great budget choice — so you can decide which one is right for your hunting style.
What Is a Single Frequency Detector?
Single frequency metal detectors transmit and receive at a fixed frequency or a selected frequency band. These machines are great in specific conditions, but they often force you to choose between depth or sensitivity to small targets.
Lower single frequencies (like 5–8 kHz) dig deeper on large, conductive targets and work well in mineralized soil, while higher frequencies (15 kHz+) are better for small items like gold nuggets and thin jewelry.
What Is a Multi-Frequency Detector?
Multi-frequency detectors send and receive many frequencies at once. This lets them simultaneously handle:
- Large, deep targets
- Small, low-conductive items
- Mineralized ground and saltwater beaches
- Trash and iron unmasking
They are more versatile out of the box and require fewer setting tweaks in varied conditions.
