The Buki metal detector from the Nature product line accompanies young explorers aged eight and over in their search for hidden metal objects such as coins or keys. Equipped with an illuminated digital display and an adjustable audio function, the device is ready for use even at dusk. The handle length can be individually adjusted, while the detection sensitivity can be variably set. Illustrated instructions make it easy to get started with the treasure hunt. A 9V battery, available separately, is required for operation.
