Material and Build

The detector is constructed from durable plastic and metal components, with the control box housing the speaker, meter, and controls. The 16.5cm waterproof search coil is designed for shallow-water use, but the main control unit is not waterproof and must be kept dry.

The search coil measures 16.5cm in diameter, providing a moderate search area for general-purpose detection. The rod can be adjusted in length to suit users of different heights, allowing comfortable standing use. The unit's compact design makes it easy to pack and transport, whether you are heading to a beach, park, or woodland area.

Uses and Placement

This metal detector is suited for outdoor treasure hunting, archaeological discovery, and hobbyist searching. Its waterproof coil expands its range to shallow water environments like streams and pond edges, where the control box remains safely above water.

Event or Professional Use

For organised treasure hunts, club events, or professional search teams, the MD-4030 offers essential detection functions without complexity. The recognition mode helps filter out unwanted metals, and the audible tone and pointer display provide clear feedback. The headphone jack allows teams to work without disturbing others, and the low battery indicator helps maintain operational readiness.

Everyday Home Use

Around the home and garden, this detector is ideal for finding lost keys, coins, jewellery, or buried pipes and cables. Its lightweight build and adjustable rod make it easy for one person to use in a backyard or local park. The full metal mode is useful for general searching, while recognition mode helps reduce time spent digging up unwanted metal objects.
