Adult Waterproof Underwater Handheld Gold Metal Detector

Product Introduction

‍‌‍‍‌‍‌‍‍‌Built to be dependable both outdoors and underwater, this gadget uses a frequency of about 20 kHz in order to give a consistent signal when picking up the usual metal items like coins and small pieces of jewelry.

In normal soil, it is capable of spotting a coin-sized metal item as deep as 50 mm. Thanks to the IP68 waterproof rating, the strong ABS body, and a battery life of 12-15 hours, it is capable of being used for a long time in the field (such as at the beach, river, or in wet ‍‌‍‍‌‍‌‍‍‌sand).
