This versatile metal detector can be used to find metals such as iron, silver, copper, etc., whether on the beach, in the garden, in the floor, or in shallow waters. The metal detector is suitable for all metal types and has a DISC function (discrimination function) that excludes the detection of trash. The metal detector can detect coin-sized objects up to 18 cm deep and larger objects up to 300 cm deep. The search coil is waterproof, so you can even find objects in shallow waters. When a metal object is detected, the detector emits summery tones. The headphone jack and adjustable volume allow you to connect headphones, which provides more privacy and helps you hear all the summery tones more clearly during treasure hunting. Thanks to the lightweight construction, you can spend hours treasure hunting without getting tired. The length of the carrying strap can be adjusted for more comfort. The metal detector is powered by a 9 V battery (not included). Note: The use of a metal detector may require a permit, approval, or license. The location where a metal detector can be used may also be restricted. Familiarize yourself with all local, state, and national laws regarding metal detection. Follow these laws. This product may not be disposed of with other household waste in the European Union.
