Multi-Frequency Metal Detector Explained: What It Actually Adds and Who Actually Needs It

by
Multi Frequency Metal Detector Explained

Multi-frequency is not one standardized detector technology. Some machines let you choose one operating frequency at a time, while others process more than one frequency within the same search mode, and those two designs solve different problems. The practical value depends on the ground, the target mix, the search mode, and the quality of the … Read more

Metal Detector Technology Types: VLF, PI, and Multi-Frequency Explained for the Field

by
Metal Detector Technology Types

The main hobby detector technologies are single-frequency VLF, pulse induction, and simultaneous multi-frequency, but none is automatically best. The useful choice depends on the target, soil, conductive salt, trash density, discrimination needs, physical fit, and budget. I treat the technology label as the beginning of the decision, not the answer. By the end, you should … Read more
