Treasure Cove 3020 Metal Detector Kit with Accessories

The Treasure Cove 3020 is a metal detector sold as a complete kit for adults hunting beaches, parks and other ground above the waterline. The coil is the waterproof part, not the machine, so this is a tool for wet sand and the shallows rather than anything you take under with you.

Who this suits

Someone who wants to start on a beach this weekend without reading a manual first. The controls are digital with no dials or knobs, and the kit already contains the headphones, bag and scoop you would otherwise buy separately, so the first outing needs nothing added.

Treasure Cove list the detector as suitable for beginner through to professional users, which in practice means the settings are adjustable enough to grow into rather than being locked to a single preset.

Skip it if you want to detect underwater. Only the coil is listed as waterproof, so the control box stays dry, and that rules out wading past your knees or anything resembling a dive.

Three detection modes, and the one that saves your afternoon

The 3020 runs three modes: All Metal, Target and Discrimination. All Metal signals on everything conductive, Target narrows to what you have asked for, and Discrimination is the one that decides whether a beach session is worth it.

Discrimination filters by target type across iron, silver and gold. On a public beach the ground is mostly bottle caps and rusted nails, both of them iron. Filtering iron out is the difference between digging every signal and digging the ones worth digging.

Six readouts on one screen

The LCD shows six things at once: detection mode, sensitivity level, battery condition, volume level, object depth and probable metal type.

Object depth is the one that changes how you dig. Knowing whether a target sits shallow or deep tells you whether to reach for the scoop or walk on, and combined with the probable metal type it lets you skip a signal before you have touched the sand. Pinpoint accuracy is listed as within inches, so the hole stays small.

Feedback comes both ways, audio through the headphones and visual on the screen, which matters on a windy beach where the tone alone is hard to read.

Ground control for beaches and mineralised soil

Salt water and mineral-rich ground throw false signals at any detector, and beaches are where that problem lives. The 3020 has an auto ground-control feature and lists false signal elimination as handled by the machine rather than by you.

Ground balance is the setting a beginner is most likely to get wrong by hand. Having it handled automatically is what makes the shoreline usable on the first outing rather than the tenth.

The waterproof coil covers wet sand and the water's edge. Treat the shaft and control box as dry equipment.

What the kit covers

The title names a kit, and this page covers that complete version. The listed accessories are padded headphones with a 6-foot cord, a carrying bag and a sand-sifting scoop.

The 6-foot cord is longer than it sounds necessary; it is what lets you set the detector down and dig without unplugging. The scoop is the accessory that decides whether you keep going after an hour, because sifting wet sand by hand is how beach hunting stops being fun.

The bottom line

A complete, adjustable beach and land detector with the three settings that matter already automated: ground balance, discrimination and depth read-out. The kit removes the usual second purchase.

It is not underwater equipment, it is not a machine for a specialist chasing deep or faint targets, and the coil being the only waterproof component is a hard limit rather than a caution. Within the shoreline it is built for, it is a sensible first detector.
