Treasure Cove metal detectors are best suited for use by beginner kids as it is really easy to use. It however has more advanced setting that make it more than a detector toy.

Pros of Treasure cove TC-3020 Metal Detector

This LCD makes operation of the machine easier than if it was being operated using knobs. It displays some operations like discrimination and targets.

Three audio tones

Treasure Cove TC-3020 metal detector has three audio tones that distinguish between items.Depending on your notch discrimination settings, you hear low tone for things like nails and nickels, medium tone for gold, copper and zinc and high tone for brass and silver. Knowing how valuable a treasure is before excavating it, enables one decide whether the target is worth the time and effort for digging it up.

Ground control

Ground control is important as it protects the metal detector from giving false signals due to ground mineralization. Having ground balance, this metal detector works well without giving false signals where there is no target.

View meter and pointer with light indicators for ferrous and non-ferrous objects

This metal detector has a view meter and pointer with light indicators that differentiate between steel/iron (ferrous metals) and silver/gold (non-ferrous metals). With this ferrous and non-ferrous metal discriminator, one will also know whether the target they came across is worth digging up for. Most ferrous targets are rusted nails, nickels and other not valuable items.

Very Low frequency (VLF) operation design

Treasure Cove metal detector uses Very Low Frequency (VLF) circuit to detect targets, hence it can detect small deep targets. For instance, it can detect a US quarter buried at 6” deep.

Adjustable sensitivity

The sensitivity of this metal detector can be adjusted when one moves from one place to another

Has all metal mode and discrimination mode

It has two detection modes; All-metal mode and Discrimination mode. With All-metal mode, the detector detects all metals while on Discrimination mode, one can discriminate targets that they are not interested in and in most cases ferrous metal targets.

Pinpoint/ Target mode

With target mode, the machine tells the precise location of the target found. Unlike some other metal detectors where one has to buy a separate pin pointer, this detector has an in-built pin pointer.

Notch discrimination

Notch discrimination enables Treasure Cove TC-3020separate targets from junk.  It is able to ignore items such as scrap metal, aluminum, nails and metal cans and only signal to valuable targets

Waterproof search coil

It has a waterproof search coil, hence can be used in beaches, muddy areas and shallow water, but it should not be submersed.


This metal detector comes with accessories like padded earphones, a durable carrying case and sand sifting scoop. It operates with two 9v batteries.

User friendly

It has an adjustable metal shaft and an arm rest.

It is designed for both right and left handed people, and it is a lightweight machine hence it is not tiresome moving with it around.

Cons of treasure cove TC-3020 Metal Detector

Gives false signals

Not often, but it gives false audio tone signals especially when the target is a combination of more than one metal.

Complex man

Being a beginner’s metal detector, the manufacturer’s manual is a bit too complicated to be understood by a beginner.

To have the metal detector work optimally, it is essential to understand its settings and notch discrimination in order to have the right targets being detected. Practice makes perfect; with time, you will be a Pro at using this and any other metal detectors.
