treasure metal detector

Coil diameters in the dataset range from small kid/portable coils (about 6.5"–7.4") up to larger search coils around 10". Larger coils provide greater ground coverage while smaller coils are more compact and better for tight or cluttered areas.

Power requirements vary across models: several full-size detectors list 2 × 9V batteries, some kid or compact models use a single 9V, and a few models operate on 2 AA batteries. Packages sometimes include batteries but often list them as required but not included.

Many models include an LCD or backlit display showing signal strength, target ID, estimated coin depth, battery level, and current mode. Common feedback options include multiple audio tones, adjustable volume levels, and modes such as sound, vibration, or both (some handheld pointers combine vibration and sound alerts).

Yes — several detectors list a pinpoint or PP mode to help center targets more precisely. Some pinpointers also provide depth markings and combined vibration/sound alerts to aid close-range locating.

Many listings specify waterproof search coils, with several citing an IP68 rating and at least one referencing 'P68' for the coil. Product notes often state the coil is waterproof while the control box or LCD is not.

Common modes include All-Metal and DISC/Notch plus pinpoint; some models add modes like Sniff, Jewelry, or memory presets. Many detectors use multi-tone audio (often three tones) to indicate metal categories, with target-ID ranges mapped to low/medium/high tone categories.
