Detectors and pinpointers

Brands: Bounty Hunter, Fisher, Garrett, Minelab, Nokta, Teknetics. Every row comes from a spec page, product page or manual that the maker publishes, read between 16 October 2026 and 17 October 2026. For a few specs a dealer page or an archived copy of the maker's page fills a gap; detector-sources.csv says which. The files hold facts only, in our own words and layout. No maker text, image or logo is copied, and no product price is included.

• A cell is empty when no source we read gives the value. not_published names those fields; nothing is estimated.
• When one maker page gives two different values for the same spec, conflicts shows both (field: first | second) and the main column then holds one of them or stays empty. Nothing is settled.
• status is current or discontinued as the maker shows it. It is empty when we could not confirm it.
• frequencies_khz lists fixed frequencies. frequency_range_khz is used instead for detectors with a user-set range; frequency_note repeats the maker's own wording, such as which frequencies apply in which mode.
• waterproof_part says which part is rated, for example the whole detector or the coil. weight_lb is the figure we use; weight_text is how the maker writes it.
• coils lists the search coils with the maker's own names: size, coil type, shape, and model code in brackets.

Land rules

Each rule is a plain-words summary of one official text: the Code of Federal Regulations on ecfr.gov, or a state code or agency page, read between 16 October 2026 and 17 October 2026. citation gives the section; kind tells what sort of rule it is, such as prohibited, allowed with limits, or removal prohibited. Some texts were read on the copy kept by Cornell's Legal Information Institute because the official site could not be read; land-rules-sources.csv marks them.

This is not legal advice. Rules change, land managers can add their own, and a text read on one date may no longer apply. Check local rules before you dig.

Not covered: Michigan and Oklahoma (no official text could be read), Florida only in part (some official pages could not be read), and every state not listed in the file. A missing state does not mean detecting is allowed there.
