The FinePower GMD121 metal detector is designed to locate metal objects in the ground at depths of up to 45 cm, utilizing the VLF low-frequency detection method. Thanks to the built-in discriminator, it can accurately identify the size and material of the detected item, allowing users to configure the device to respond specifically to copper, silver, or gold objects. For scanning, the metal detector uses a round concentric coil with a waterproof design, allowing operation even in rainy conditions.
Comfort during prolonged treasure hunting with the FinePower GMD121 is provided by an integrated armrest and a low weight of 900 g. Audio signals are output via the built-in speaker, and a headphone jack is also provided. The device operates fully autonomously from two 9 V Krona (PP3) batteries.
