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
