This junior metal detector can be used to locate metals like iron, silver, copper, etc. on the beach, in the garden, on the floor, or in shallow water. The metal detector can detect coin-sized objects up to 10 cm deep and larger objects up to 120 cm deep. The search coil is waterproof, so you can detect objects in shallow water. When a metal object is detected, the LCD screen will show an arrow and the detector will generate buzzer sounds. Thanks to the lightweight construction, you can go treasure hunting without fatigue for hours. The shaft length can be adjusted for improved comfort. The detector also has a non-slip grip for a comfortable and secure hold. The metal detector is powered by a 9 V battery (not included). Note: The use of a metal detector might require permission, a permit or a license. The location where a metal detector can be used might also be restricted. Familiarise yourself with all local, state, and national laws related to metal detecting. Follow these laws.
