If calibration is needed, the instructions say to hold the probe in the air, press the button once and wait about 10 seconds. They also advise having the battery well charged.

Listing details to confirm

The listing’s power claims conflict: it describes an internal rechargeable battery charged by USB-C with over eight hours’ runtime, but the details also say “1 AAA batteries required. (included)”. Its title gives a 7.36-inch coil and a 24–35-inch handle, while the details list 18.7 centimetres for the coil and 35 inches as extended length. Dimensions also appear as both “40L x 5W x 17H centimetres” and “40 x 5 x 17 cm; 910 g”. Confirm the selected listing’s configuration and measurements before purchase. The waterproof claim applies to the search coil, not necessarily the full detector. The seller describes detection beyond four inches for coins, keys and jewellery, but this is a performance claim rather than an independently verified result.

Who is it for?

A good fit for

Children looking for a simple detector for supervised beach or outdoor treasure-hunting activities.
Families who want an adjustable shaft and LCD target display, subject to confirming the battery and coil details.

Less suited to

Buyers who need a confirmed whole-detector waterproof rating or verified detection performance.
Buyers who require a clearly established battery type, charging arrangement or exact dimensions without checking the listing.

Aggregate ratings lean positive, with ratings represented in the four- and five-star categories. This is a small rating sample and includes no comment-level feedback, so it does not establish what buyers liked or how the detector performs. For a child’s introductory detector, the adjustable shaft and LCD are relevant stated features, while the conflicting battery and size details remain practical points to resolve.

Frequently asked questions

Is the Flashseen MD-3012 rechargeable?

The feature text claims an internal rechargeable battery and USB-C charging, while the product details say one AAA battery is required and included. Confirm which configuration applies to the selected listing.

Can the detector be used underwater?

The listing calls the search coil waterproof, but does not establish that the entire detector is waterproof. Do not assume the display or handle can be submerged.

How long is the shaft?

The title and feature text describe a shaft adjustable from 24 to 35 inches. The details also list 35 inches as the extended length, so check the selected listing if exact measurements matter.

What does the detector do when it finds a target?

The listing says the signal strengthens and the beep becomes faster and louder as the detector gets closer to the target. It also lists an LCD display, without specifying exactly what information it shows.
