Detection of 3 Types of Metals: The MMD02 detects ferrous metals with a low-tone alarm, low conductivity non-ferrous metals with a medium-tone alarm, and high conductivity non-ferrous metals with a high-tone alarm.

Fantastic Disc Button: By pressing the DISC button, you can toggle between detection modes: once for ferrous metals, twice to exclude low conductivity non-ferrous metals, and three times to return to normal detection. This feature helps you locate metals more efficiently, with different icons displayed on the screen based on detection depth.

Adjustable Detection Rod: The rod can be adjusted from 61 cm to 90 cm in length, making it suitable for both adults and children. It also includes a non-slip strip for easy handling and a waterproof coil for shallow water detection (note: the detector itself is not waterproof).

Fun for Everyone: The adjustable length and various features make the MMD02 ideal for treasure hunting enthusiasts of all ages.
