Features and Construction

The MD4090 combines materials that offer rigidity and lightness. Its construction focuses on practicality for field use without unnecessary complexity.
Material and Build
The detector uses alloy for the main shaft and control housing, giving a sturdy feel without being heavy. Plastic components, particularly the search coil, help keep the overall weight down while still functioning as intended for detecting metal objects underground. The combination of these materials makes the unit easy to carry and manoeuvre across different terrains.
Size and Practical Fit
With overall dimensions of 1070x220mm, this metal detector is sized for comfortable ground scanning. The length allows you to stand upright while sweeping, reducing back strain during long searches. The width of the coil (part of the 220mm measurement) covers a reasonable area per sweep, balancing detail with efficiency.
Uses and Placement

This detector is designed for outdoor environments where buried metal objects may be found. It is suited to archaeological field surveys, hobbyist treasure hunting, and general outdoor metal detection.
Archaeological and Professional Use
For archaeological teams, the MD4090 provides a lightweight tool for initial site surveys. Its ability to locate metal objects underground helps identify potential areas of interest before more detailed excavation begins. The alloy construction withstands regular outdoor use in fields and forests.
Everyday Hobby Use
Hobbyists will appreciate the detector's portability and straightforward operation. It is suitable for beachcombing, park searches, or countryside walks where metal detecting is permitted. The 1500g weight means you can carry it for hours without discomfort.
Benefits and Buying Value

This detector offers a practical balance of weight, build, and size for those who need a reliable tool for metal detection tasks. Its simple material design keeps costs sensible while providing the necessary functionality.
Low Maintenance and Durability
The alloy and plastic build requires minimal care – simply wipe clean after use. With no complex electronics to calibrate, the MD4090 is ready to use straight from the package. This simplicity reduces the need for specialist maintenance.
