Excellent product comes with batteries and a doc in French! We had fun in the garden with the children. We found a bunch of metal objects. We even hid a piece of 2 the device has detected in the earth. Amazing !!!!! And it makes the difference between coins and old nails or capsules of beer! I highly recommend this product !!! Attention circulates false aircraft of this type (not necessarily of this brand!) I read that in a magazine specializing ... Have fun and knows discover a treasure !!!!! ;-)
